[PATCH] added typechecking ot sparc64 ioremap()
ioremap() made inlined function on sparc64; that had caught one bogosity in
drivers, actually - cpwatchdog.c passed sizeof(structure that was never
declared) as the second argument to ioremap(). It went unnoticed since
that argument was never used in the body of macro, so it disappeared without
a trace...

[PATCH] smbfs protocol fixes
From: <Urban.Widmark@enlight.net>
The memset is because it was previously possible to send always the same CIFS
fragment and use this to increase the data counters. When the data counter
"exceeds" the amount of bytes expected this will return the buffer only
partially initialised... With findfirst etc requests this should allow
leaking kernel memory content.
The other thing is that the data is only returned when data_tot and parm_tot
both "exceed" the expected values. Previously it was possible to create a
sequence of CIFS fragments that allowed exceeding the counters. The calling
functions then would believe they received a number of bytes that does not fit
into the allocated buffer.

In ia32 emulation, the amd64 kernel refuses the ioctls TIOCSBRK and

compatibility list.
Since all architectures have these ioctls ("m68knommu" inherits them from
"m68k", "um" from its host) and use the same code, I think adding them to
compat_ioctl.h is the correct choice (as opposed to adding them to
arch/x86_64/ia32/ia32_ioctl.c).

[PATCH] ppc64: fix XICS startup function to enable as well
When the generic IRQ patch went in, it changed the behaviour of setup_irq
(compared to the previous ppc64 version) in that we now don't call the
handler's enable function if it has a startup function. The XICS interrupt
controller has a startup function, and so we weren't getting any interrupts
through the XICS because they never got enabled. This patch adds a call to
xics_enable_irq to xics_startup and fixes the problem.

MTD: NOR flash chip driver updates
Mostly from Eric Biederman for supporting BIOS flash.
- Move support firmware hub style lock and unlock into fhw_lock.h (from cfi_cmdset_0002)
- Move cfi_varsize_frob into cfi_util from cfi_cmdset_0001.c and cfi_cmdset_0002.c
- reduce gen_probe probe failuers to a debug level message
- Modify cfi_fixup to take a struct mtd_info instead of a struct map_info
So that the fixup routines can modify the mtd functions.
- Modify cfi_cmdset_0001() to allocate and initialize the mtd structure
before calling cfi_fixup.
- Modify cfi_cmdset_0002() to allocate and initialize the mtd structure
before calling cfi_fixup.
- Refactor the hard coded fixups in cfi_cmdset_0001 and cfi_cmdset_0002
so the improved cfi_fixup infrastructure.
- Rewrote amd76xrom and ichxrom.
They now report their starting physical address in their name.
They now both handle multiple bankwidth configurations
They both can create multipe mtd devices.
They both now assume the rom windows are properly opened by the BIOS
or whatever runs previous to them.
Their code is now synchromized so it is almost identical,
and could be a starting point for a x86_rom_probe.

Shared Reed-Solomon ECC library
The attached patch contains a shared Reed-Solomon Library analogous to
the shared zlib.
(N)AND FLASH is gaining popularity and there are a lot of ASIC/SoC/FPGA
controllers around which implement hardware support for Reed-Solomon
error correction. As usual they use different implementations
(polynomials etc.). So it's obvious to use a shared library for the
common tasks of error correction.
A short scan through the kernel revealed that at least the ftape driver
uses Reed-Solomon error correction. It could be easily converted to use
the shared library code.
The encoder/decoder code is lifted from the GPL'd userspace RS-library
written by Phil Karn. I modified/wrapped it to provide the different
functions which we need in the MTD/NAND code.
The library is tested in extenso under various MTD/NAND configurations.
The lib should be usable for other purposes right out of the box.
Adjustment for currently not implemented functionality is an easy task.
I'm willing to take the maintainership of the library.

[IA64-SGI] sparse cleanups & misc fixes for sn2
This is a big patch mostly because I trimmed shub_mmr.h down from 17M to 11k
or so. It fixes a number of things sparse discovered and removes some dead
code, fixes up some prototypes, etc. Of note:
o sn_proc_fs.c was directly dereferencing user pointers, fixed
o sn_hwperf.c was missing an include and was using asm-ia64 directly
o the I/O routines were all missing proper sparse annotations
o dead code in prominfo_proc.c has been removed
o fix generic build by putting numionodes into asm/sn/io.h
With this patch applied, the check build is pretty clean. The sn_console bit
depends on some of the other changes, so it's included here.

Sometimes, it's useful to have locking. Especially when we're
talking about time keeping.
It would appear that shemminger's patch of 5th February 2003
completely missed updating _ANY_ ARM timer implementations and,
because linux-arch didn't exist at the time, there appears to
have been no notification to any architecture developer that
maybe, just maybe, some work was required.
One wonders how many other changes are in the kernel which

[IA64] top level scheduler domain for ia64
Some have noticed that the overlapping sched domains code doesn't quite work
as intended (it results in disjoint domains on some machines), and that a top
level, machine spanning domain is needed. This patch from John Hawkes adds
it to the ia64 code. This allows processes to run on all CPUs in large
systems, though balancing is limited. It should go to Linus soon now
otherwise large systems will only have ~16p (depending on topology) usable by
the scheduler. I sanity checked it on a small system after rediffing John's
original, and he's done some testing on very large systems.
Nick, can you buy off on the sched.c change? Alternatively, do you want to
send that fix separately John? Nick did indeed ACK this change, but it isn't
dependent on this ia64 specific part ... so it's going to be submitted
separately.

[PATCH] ext3 directio block leak fix
The orphan list holds inodes that need to be truncated on recovery. In the
O_DIRECT case, it's used if we extend the inode --- the truncate on recovery
means we'll recover the newly-allocated disk blocks if we crash after the IO
starts but before i_size is updated on disk.
Now, the orphan list is *also* used to delete inodes that are unlinked but
still-open. Those get truncated but also deleted on recovery.
The orphan list is held both in memory and on disk. So the rules are that the
inode can't be reclaimed while on the orphan list. There are only two cases
--- either the inode is actively being written(O_DIRECT) or truncated (in
which case the inode is by definition not going to be reused), or it's
unlinked but still open (again, non-reclaimable).
But in the case where you're truncating or write(O_DIRECT)ing a file that is
*ALSO* unlinked, there's a problem --- the final unlink would put the inode on
the orphan list, but the write/truncate would try to add/remove it. End
result is that the inode disappears from the orphan list while it's still
unlinked-but-in-use.
That's just a leak-on-crash, it's not going to be detectable in normal use.
But it's still a bug, and the way we fix it is for direct-IO and truncate not
to do the ext3_orphan_del if the file is unlinked (ie. i_nlink==0).

[PATCH] nfs4 lease: add a lock manager copy lock callback
The following patches provide an interface to the lease subsystem in the
current VFS locking code. NFSv4 delegations and Samba op-locks share most
architecture features. The version 4 NFS server delegation implementation
should use leases to co-ordinate behavior between local, Samba, and NFS
access.
The main design points are
- Seperate the fcntl interface from the file_lock FL_LEASE processing in
fcntl_setlease, creating __setlease() called by fcntl_setlease()
- Add new lock_manager callbacks to enable lease properties to be set,
leases to be broken, and leases to be cleaned up: with default callbacks
preserving the current fcntl_setlease properties.
- Add a new interface, setlease() which also calls __setlease(), and
remove_lease() for kernel lease managers (e.g. the v4 NFS server)
This patch:
Add a lock manager copy lock callback to locks_copy_lock() so that nfsd can
set lease properties.

This patch adds a REISERFS_UNSUPPORTED_OPT flag to denote when a mount

[PATCH] transmeta efficeon support and cpuid update
This patch adds efficeon as a cpu option, and makes a small update to the
transmeta cpuid code. (i wasn't sure if the various doc files are UTF-8...
if they are, then the e should be a U-275 ;)
The compile options may not be ideal, but they're probably close. i used
-march=pentium3, but -march=pentium4 would have been good enough too.
The cpuid update teaches transmeta.c about the extended processor revision
present in cpuid level 0x80860002... the external documentation does not
indicate how to break apart this field, and instructs only that the 32-bit
value should be printed in hex (alas).

[PATCH] "console=" parameter ignored
I've noticed that under specific circumstances the "console=" kernel
parameter is ignored. This happens when EARLY_PRINTK is enabled and the
serial console is the only available. In this case unregister_console()
when called for the early console sets preferred_console back to -1
replacing the value that was recorded by console_setup() -- the order of
calls is as follows:
1. register_console() -- for the early console,
2. console_setup() -- recording the console index for the real console,
3. unregister_console() -- for the early console, erasing the console
index recorded above,
4. register_console() -- for the real console, picking up the first device
available, instead of the selected one.
I've observed this problem with a DECstation system using ttyS3 -- its
default console device from the firmware's point of view.
The solution is to restore the setting of "console=" upon
unregister_console(). This made a snapshot of 2.4.26 work for me. I
wasn't able to test the changes with 2.6 because DECstation drivers don't
support it yet, but the code responsible for console selection appears
functionally the same. So I've concluded it needs the same change. Here's
a patch.

[PATCH] lockd: remove hardcoded maximum NLM cookie length
At the moment, the NLM cookie length is fixed to 8 bytes, while 1024 is the

Therefore we need to make the length dynamic (which I set to 32 bytes).

to patch properly (also added some stylish NIPQUAD fixes).
From: Neil Brown <neilb@cse.unsw.edu.au>

[PATCH] slab: reduce fragmentation due to kmem_cache_alloc_node
Attached is a patch that fixes the fragmentation that Badri noticed with
kmem_cache_alloc_node.
kmem_cache_alloc_node tries to allocate memory from a given node. The
current implementation contains two bugs:
- the node aware code was used even for !CONFIG_NUMA systems. Fix:
inline function that redefines kmem_cache_alloc_node as kmem_cache_alloc
for !CONFIG_NUMA.
- the code always allocated a new slab for each new allocation. This
caused severe fragmentation. Fix: walk the slabp lists and search for a
matching page instead of allocating a new page.
- the patch also adds a new statistics field for node-local allocs. They
should be rare - the codepath is quite slow, especially compared to the
normal kmem_cache_alloc.

Without this patch, commands sent to ide-floppy devices without media

ide-floppy: ide: I/O error, pc = 0 key = 2, asc = 3a asq = 0
ide-floppy: ide: I/O error, pc = 1b key = 2, asc = 3a asq = 0
ide-floppy: ide: I/O error, pc = 23 key = 2, asc = 3a asq = 0
ide-floppy: ide: I/O error, pc = 1e key = 2, asc = 3a asq = 0

[PATCH] EDD: use EXTENDED READ command, add CONFIG_EDD_SKIP_MBR
Some controller BIOSes have problems with the legacy int13 fn02 READ
SECTORS command. int13 fn42 EXTENDED READ is used in preference by most
boot loaders today, so lets use that. If EXTENDED READ fails or isn't
supported, fall back to READ SECTORS.
This hopefully resolves the three reports of BIOSes which would either
long-pause (30+ seconds) or hang completely on the legacy READ SECTORS
command.
This also adds CONFIG_EDD_SKIP_MBR to eliminate reading the MBR on each
BIOS-presented disk, in case there are further problems in this area.

[PATCH] hvc_console fix to prevent oops and late hangup and write operations
This patch prevents execution of hvc_write() and hvc_hangup() after the tty
layer has executed a final hvc_close() against a device. This patch
provides a better method than was previously used. tty->driver_data is no
longer invalidated so we'll no longer get oopses when the tty layer allows
late hangup() and write() operations.
- Removed silly tty->driver_data = NULL; from hvc_close which prevents
possible oops in hvc_write() and hvc_hangup() due to improperly acting
ldisc close ordering.
- Added hp->count <= 0 check to hvc_write() and hvc_hangup() to prevent
execution of these function after hvc_close() has been invoked by the tty
layer. Same tty ldisc issues as above are the reason.
- Added some comments to clarify the situation.
- Awaiting a forth coming patch from Alan Cox which should clean up the
close ordering and prevent the late hangup and write ops from happening.

ChangeSet@1.2010.2.87, 2004-10-20 08:31:19-07:00, clameter@sgi.com
[PATCH] Posix compliant cpu clocks
POSIX clocks are to be implemented in the following way according
to V3 of the Single Unix Specification:
1. CLOCK_PROCESS_CPUTIME_ID
Implementations shall also support the special clockid_t value
CLOCK_PROCESS_CPUTIME_ID, which represents the CPU-time clock of the
calling process when invoking one of the clock_*() or timer_*()
functions. For these clock IDs, the values returned by clock_gettime() and
specified by clock_settime() represent the amount of execution time of the
process associated with the clock.
2. CLOCK_THREAD_CPUTIME_ID
Implementations shall also support the special clockid_t value
CLOCK_THREAD_CPUTIME_ID, which represents the CPU-time clock of the
calling thread when invoking one of the clock_*() or timer_*()
functions. For these clock IDs, the values returned by clock_gettime()
and specified by clock_settime() shall represent the amount of
execution time of the thread associated with the clock.
These times mentioned are CPU processing times and not the time that has
passed since the startup of a process. Glibc currently provides its own
implementation of these two clocks which is designed to return the time
that passed since the startup of a process or a thread.
Moreover Glibc's clocks are bound to CPU timers which is problematic when the
frequency of the clock changes or the process is moved to a different
processor whose cpu timer may not be fully synchronized to the cpu timer
of the current CPU. This patchset results in a both clocks working reliably.
The patch also implements the access to other the thread and process clocks
of linux processes by using negative clockid's:
1. For CLOCK_PROCESS_CPUTIME_ID: -pid
2. For CLOCK_THREAD_CPUTIME_ID: -(pid + PID_MAX_LIMIT)
This allows
clock_getcpuclockid(pid) to return -pid
and
pthread_getcpuiclock(pid) to return -(pid + PID_MAX_LIMIT)
to allow access to the corresponding clocks.
Todo:
- The timer API to generate events by a non tick based timer is not
usable in its current state. The posix timer API seems to be only
useful at this point to define clock_get/set. Need to revise this.
- Implement timed interrupts in mmtimer after API is revised.
The mmtimer patch is unchanged from V6 and stays as is in 2.6.9-rc3-mm2.
But I expect to update the driver as soon as the interface to setup hardware
timer interrupts is usable.

The following patch will have the committed memory limit (per the current

It's presently somewhat difficult to use the strict memory overcommit

[PATCH] v4l: cx88 driver update
This is a major update of the cx88 driver. Main new feature is support
for the MPEG PCI function of the cx2388x chips. The changes in detail:
* A bunch of code restructions, to allow multiple modules (one per PCI
function) work on top of the core module.
* Add a new module with common code for the mpeg PCI function.
* Add a new module to support mpeg encoder cards (connexant
"blackbird" reference design). That one is not much tested yet and
may have bugs. They can be easily workarounded by not loading the
module through, it isn't needed to capture uncompressed video.
* Add a new module to support DVB cards. That one is better tested
than the blackbird one, but it needs additional cutting-edge stuff
from the dvb project, thats why it is disabled in Kconfig for now.
* Several cleanups along the way: use kthread, use msleep(), drop some
2.4.x compatibility code, move insmod options to 2.6 style, ...
* adapt code to the video-buf changes.
* suspend fixes.
* as usual some new tv cards.

[PATCH] v4l: avoid using struct file ptrs in video-buf
This patch makes the video-buf helper module pass through a void pointer
instead of a struct file pointer, that makes the code also usable when no
file pointer is available. This is needed for when using the video-buf
infrastructure to manage DMA buffers for DVB cards.
The file pointer was used by the videobuf_queue_ops callbacks to get the
drivers private data via file->private_data, now a pointer to the drivers's
private data can be passed directly.
Adaptions of the drivers follow with separate patches.

[PATCH] lighten mmlist_lock
Let's lighten the global spinlock mmlist_lock.
What's it for?
1. Its original role is to guard mmlist.
2. It later got a second role, to prevent get_task_mm from raising
mm_users from the dead, just after it went down to 0.
Firstly consider the second: __exit_mm sets tsk->mm NULL while holding
task_lock before calling mmput; so mmlist_lock only guards against the
exceptional case, of get_task_mm on a kernel workthread which did AIO's
use_mm (which transiently sets its tsk->mm without raising mm_users) on an
mm now exiting.
Well, I don't think get_task_mm should succeed at all on use_mm tasks.
It's mainly used by /proc/pid and ptrace, seems at best confusing for those
to present the kernel thread as having a user mm, which it won't have a
moment later. Define PF_BORROWED_MM, set in use_mm, clear in unuse_mm
(though we could just leave it), get_task_mm give NULL if set.
Secondly consider the first: and what's mmlist for?
1. Its original role was for swap_out to scan: rmap ended that in 2.5.27.
2. In 2.4.10 it got a second role, for try_to_unuse to scan for swapoff.
So, make mmlist a list of mms which maybe have pages on swap: add mm to
mmlist when first swap entry is assigned in try_to_unmap_one (pageout), or
in copy_page_range (fork); and mmput remove it from mmlist as before,
except usually list_empty and there's no need to lock. drain_mmlist added
to swapoff, to empty out the mmlist if no swap is then in use.
mmput leave mm on mmlist until after its exit_mmap, so try_to_unmap_one can
still add mm to mmlist without worrying about the mm_users 0 case; but
try_to_unuse must avoid the mm_users 0 case (when an mm might be removed
from mmlist, and freed, while it's down in unuse_process): use
atomic_inc_return now all architectures support that.
Some of the detailed comments in try_to_unuse have grown out of date:
updated and trimmed some, but leave SWAP_MAP_MAX for another occasion.

[PATCH] FAT: Fix the race bitween fat_free() and fat_get_cluster()
This patch fixes the race condition
| fat_free | fat_get_cluster
+------------------------------+-----------------------
fat_cache_lookup()
(get the copy of cache)
fat_cache_inval_inode()
(invalidate caches on inode)
fat_cache_add()
(update/add the getted cache)
The above race has possible that invalidated cache is added.
This patch fixes the race condition by adding the cache-id to copy of cache.

[PATCH] FAT: rewrite the cache for file allocation table lookup
This rewrites the cache stuff for file allocation table (FAT).
This cache stocks the more pieces of FAT-chain by counting the number
of contiguous data blocks. And if cache hit, since a block number can
calculate without looking FAT-chain up, fat_get_block() become more
fast.
But if data blocks was fragmenting, unfortunately this cache is unuseful.

[PATCH] module_param_array() should take a pointer
module_param_array() takes a variable to put the number of elements in.
Looking through the uses, many people don't care, so they declare a dummy
or share one variable between several parameters. The latter is
problematic because sysfs uses that number to decide how many to display.
The solution is to change the variable arg to a pointer, and if the pointer
is NULL, use the "max" value. This change is fairly small, but fixing up
the callers is a lot of (trivial) churn.

[IA64] Avoid a rare deadlock during unwind
There is a rare deadlock condition during unwind script creation. If
build_script() is interrupted in the middle of creating the script, it
holds the script write lock. If the interrupt handler needs to call
unwind for some failure condition, unwind will try to read the
incomplete script and will deadlock on the script lock.
The fix is to disable interrupts while building the script, so
interrupt handlers never see partial scripts.
Promoting spin_lock_irqsave() from script_new() to find_save_locs()
changes the indentation, so the patch looks bigger than it really is.

[PKT_SCHED]: CBQ; Destroy filters before destroying classes.
CBQ destroys its classes by traversing the hashtable and thus classes
are not destroyed from root to leafs which means that class Y being
a subclass of class X may be destroyed before X. This is a problem
if a filter is attached to class X (parent) classifying into class Y
(result). In case Y gets deleted before X the filter references an
already deleted class while trying to unbind (cbq_unbind_filter).
Therefore all filters must be destroyed before destroying classes. An
additional BUG_TRAP has been added to document this not so obvious case.
The BUG can be triggered with the following commands:
qdisc add dev root handle 10:0 cbq bandwidth 100Mbit avpkt 1400 mpu 64
class add dev parent 10:0 classid 10:12 cbq bandwidth 100mbit rate 100mbit allot 1514 prio 3 maxburst 1 avpkt 500 bounded
class add dev parent 10:12 classid 10:13 cbq bandwidth 100mbit rate 100mbit allot 1514 prio 3 maxburst 1 avpkt 500 bounded
filter add dev parent 10:12 protocol ip prio 10 u32 match ip protocol 6 0xff flowid 10:13
qdisc del dev root
The deletion ordering in the above case is: 10:0 -> 10:13 -> 10:12

[PATCH] I2C: Fourth auto-fan control interface proposal
Here comes my fourth (and hopefully last) sysfs interface proposal for
implementing auto-fan control in 2.6. Previous proposals have been
discussed here:
[1] http://archives.andrew.net.au/lm-sensors/msg07517.html
[2] http://archives.andrew.net.au/lm-sensors/msg08049.html
[3] http://archives.andrew.net.au/lm-sensors/msg18008.html
The interface is still made up of two parts: per fan temp channels
selection, and trip points selection. Changes from the third proposal:
pwm[1-*]_enable value 2 is now used to explicitely state the auto pwm
mode. This was proposed by Mark D. Studebaker [4].
[4] http://archives.andrew.net.au/lm-sensors/msg18011.html
Temp channels selection
=======================
Renamed files from fan[1-*]_auto_channels to
pwm[1-*]_auto_channels_temp. The change from fan tp pwm is to match the
recent renaming suggested by Mark M. Hoffman [5]. The "_temp" suffix is
to leave some room for a "_fan" suffix at a later time if new chips
drive auto pwm according to fan speeds instead of temperature.
[5] http://archives.andrew.net.au/lm-sensors/msg18797.html
Trip points
===========
Trip points are now numbered (point1, point2, etc...) instead of named
(_off, _min, _max, _full...). This solves the problem of various chips
having a different number of trip points. The interface is still chip
independent in that it doesn't require chip-specific knowledge to be
used by user-space apps.
The reason for this change is that newer chips tend to have more trip
points. the LM63 has 8, the LM93 has no less than 12. Also, I read in
the LM63 datasheet that ideal pwm vs temperature curve were parabolic in
shape. Seems hard to achieve this if we arbitrarily lock the number of
trip points to 3 ;)
I also introduced an optional hysteresis temperature for trip points.
The LM63 has this. Since it makes full sense I'd expect other chips to
propose this as well.
As before, there are two sets of files, each chip driver picks the one
matching its internal model: trip points are either temperature
channel-dependent (ADM1031...) or pwm channel-dependent (IT87xx...). If
we ever come accross fan speed-driven pwm outputs where trip points are
fan channel-dependent we may have to offer a third set of files. We'll
see when/if this happens.
I hope I have taken everyone's comments and advice into account and we
can make this interface proposal part of the sysfs interface standard
now. I'm sorry it took so long. Comments welcome.

[IA64-SGI] Double spin_unlock in bte.c
If all bte interfaces are in use, the current code will leave the
bte pointer set when exiting from the loop trying to locate an
interface to use. This results in two processes using the same
interface and both trying to free the same one. With a
premptible kernel, this results in the preempt count getting
off.

[ARM] Sanitise Footbridge machine class.
Footbridge was suffering from a little lack of care and attention;
it still had the nasty arch.c file with all the associated #ifdef
gross-ness that entailed.
Re-jig footbridge support so that each machine type contains all
the necessary support code, with a separate common implementation
which they all share.

[ARM] Rehash iwmmxt signal handling.
In the near future, VFP will want to save state onto the user stack.
Therefore, separate out the iwmmxt specific parts, and implement

This is necessary because iwmmxt and VFP both use special CPU
instructions to load and/or save their state.

[PATCH] profile: 512x Altix timer interrupt livelock fix
I've been informed that /proc/profile livelocks some systems in the timer
interrupt, usually at boot. The following patch attempts to amortize the
atomic operations done on the profile buffer to address this stability
concern. This patch has nothing to do with performance; kernels using
periodic timer interrupts are under realtime constraints to complete
whatever work they perform within timer interrupts before the next timer
interrupt arrives lest they livelock, performing no work whatsoever apart
from servicing timer interrupts. The latency of the cacheline bounce for
prof_buffer contributes to the time spent in the timer interrupt, hence it
must be amortized when remote access latencies or deviations from fair
exclusive cacheline acquisition may cause cacheline bounces to take longer
than the interval between timer ticks.
What this patch does is to create a pair of per-cpu open-addressed
hashtables indexed by profile buffer slot holding values representing the
number of pending profile buffer hits for the profile buffer slot. When
this hashtable overflows, one iterates over the hashtable accounting each
of the pairs of profile buffer slots and hit counts to the global profile
buffer. Zero is a legitimate profile buffer slot, so zero hit counts
represent unused hashtable entries. The hashtable is furthermore protected
from flush IPI's by interrupt disablement.
In order to flush the pending profile hits for read_profile(), this patch
flips betweeen the pairs of per-cpu profile buffer by signalling all cpus
to flip via IPI at the time of read_profile(), followed by doing all the
work to flush the profile hits from the older per-cpu buffers in the
context of the caller of read_profile(), with exclusion provided by a
semaphore ensuring that only one caller of profile_flip_buffers() may
execute at a time, and using interrupt disablement to prevent buffer flip
IPI's from altering the hashtables or flip state while an update is in
progress. The flip state is per-cpu so that remote cpus need only disable
interrupts locally for synchronization, which is both simple and
busywait-free for remote cpus. The flip states all change in tandem when
some cpu requests the hashtables be flipped, and the requester waits for
the completion of smp_call_function() for notification that all cpus have
finished flipping between their hashtables. The IPI handler merely toggles
the flip state (which is an array index) between 0 and 1.
This is expected to be a much stronger amortization than merely reducing
the frequency of profile buffer access by a factor of the size of the
hashtable because numerous hits may be held for each of its entries. This
reduces what was before the patch a number of atomic increments equal to
what after the patch becomes the sum of the hits held for each entry in the
hashtable, to a number of atomic_add()'s equal to the number of entries in
the per_cpu hashtable. This is nondeterministic, but as the profile hits
tend to be concentrated in a very small number of profile buffer slots
during any given timing interval, is likely to represent a very large
number of atomic increments. This amortization of atomic increments does
not depend on the hash function, only the sharp peakedness of the
distribution of profile buffer hits.
This algorithm has two advantages over full-size per-cpu profile buffers.
The first is that the space footprint is much smaller. Per-cpu profile
buffers would increase the space requirements by a factor of
num_online_cpus(), where this algorithm only requires one page per cpu.
The second is that reading the profile state is much faster, because the
state that must be traversed is exactly the above space consumers, and the
relative reduction in size concomitantly reduces the time required for a
read operation.
I also took the liberty of adding some commentary to the comments at the
beginning of the file reflecting the major work done on profile.c in recent
months and describing what the file implements.
The reporters of this issue have verified that this resolves their timer
interrupt livelock on 512x Altixen. In my own testing on 4x logical
x86-64, this patch saw a rate of about 18 flushes per minute under load, or
about one flush every 3 seconds, for about 38.4 atomic accesses to the
profile buffer per second per cpu in one of the algorithm's worst cases,
about 3.84% of the number of atomic profile buffer accesses per second per
cpu as a normal kernel would commit. This represents a twenty-six-fold
increase in the scalability on SMP systems with 4KB PAGE_SIZE, i.e. with a
4KB PAGE_SIZE, the number of atomic profile buffer accesses per second per
cpu is reduced by a factor of 26, thereby increasing the number of cpus a
system must have before it would experience a timer interrupt livelock by a
factor of 26, with the proviso that cacheline bounces must take the same
amount of time to service. This increase in the scalability of the kernel
is expected to be much larger for ia64, which has a large PAGE_SIZE,
because the distribution of profile buffer hits is so sharply peaked that
doubling the hashtable size will much more than double the amortization
factor. In fact, only 19 flushes were observed on a 64x Altix over an
approximately 10 minute AIM7 run, and 1 flush on a 512x Altix over the
course of an entire AIM7 run, for truly vast effective amortization
factors.
A prior version of this patch, which did not include the node-local
hashtable allocation and bounded collision chains has been successfully
tested on 64x and 512x ia64 vs 2.6.9-rc2, 8x ia64 vs. 2.6.9-rc2-mm1, 4x
x86-64 vs. 2.6.9-rc2-mm1, and 6x sparc64 vs. 2.6.9-rc2-mm1. This patch
minus the hashtable initialization fix has been successfully tested on 2x
ppc64, 2x alpha, 8x ia64, 6x sparc64, and 4x x86-64, all vs.
2.6.9-rc2-mm1. This precise version of the patch has been successfully
tested on 8x ia32 against 2.6.9-rc2-mm1 and 6x sparc64 vs. both
2.6.9-rc2-mm1 and 2.6.9-rc2-mm2.

[PATCH] SELinux: allow all filesystems to specify fscreate mount option
The patch below allows all types of filesystems to specify the fscreate
mount option (which is used to specify the security context of the
filesystem itself). This was previously only available for filesystems
with full xattr security labeling, but is also potentially required for
filesystems with e.g. psuedo xattr labeling such as devpts and tmpfs.
An example of use is to specify at mount time the fs security context of a
tmpfs filesystem, overriding the default specified in policy for that
filesystem.

[PATCH] Remove d_bucket
Tested using dcachebench and hevy rename test.
http://lse.sourceforge.net/locking/dcache/rename_test/
While going over dcache code, I realized that d_bucket which was introduced
to prevent hash chain traversals from going into an infinite loop earlier,
is no longer necessary. Originally, when RCU based lock-free lookup was
first introduced, dcache hash chains used list_head. Hash chain traversal
was terminated when dentry->next reaches the list_head in the hash bucket.
However, if renames happen during a lock-free lookup, a dentry may move to
different bucket and subsequent hash chain traversal from there onwards may
not see the list_head in the original bucket at all. In fact, this would
result in the list_head in the bucket interpreted as a list_head in dentry
and bad things will happen after that. Once hlist based hash chains were
introduced in dcache, the termination condition changed and lock-free
traversal would be safe with NULL pointer based termination of hlists.
This means that d_bucket check is no longer required.
There still exist some theoritical livelocks like a dentry getting
continuously moving and lock-free look-up never terminating. But that
isn't really any worse that what we have. In return for these changes, we
reduce the dentry size by the size of a pointer. That should make akpm and
mpm happy.

[PATCH] Fix dcache lookup
__d_lookup() has leftover stuff from earlier code to protect it against
rename. The smp_rmb() there was needed for the sequence counter logic.
Original dcache_rcu had :
+ move_count = dentry->d_move_count;
+ smp_rmb();
+
if (dentry->d_name.hash != hash)
continue;
if (dentry->d_parent != parent)
continue;
This was to make sure that comparisons didn't happen before before the
sequence counter was snapshotted. This logic is now gone and memory
barrier is not needed. Removing this should also improve performance.
The other change is the leftover smp_read_barrier_depends(), later
converted to rcu_dereference(). Originally, the name comparison was not
protected against d_move() and there could have been a mismatch of
allocation size of the name string and dentry->d_name.len. This was
avoided by making the qstr update in dentry atomic using a d_qstr pointer.
Now, we do ->d_compare() or memcmp() with the d_lock held and it is safe
against d_move(). So, there is no need to rcu_dereference() anything. In
fact, the current code is meaningless.

[PATCH] pidhashing: enforce PID_MAX_LIMIT in sysctls
The pid_max sysctl doesn't enforce PID_MAX_LIMIT or sane lower bounds.
RESERVED_PIDS + 1 is the minimum pid_max that won't break alloc_pidmap(), and
PID_MAX_LIMIT may not be aligned to 8*PAGE_SIZE boundaries for unusual values
of PAGE_SIZE, so this also rounds up PID_MAX_LIMIT to it.

[PATCH] Add VIDIOC_S_CTRL_OLD to matroxfb
For several months I'm receiving complaints from matroxfb users that v4lctl
suddenly stops working for them on kernel upgrade.
Problem is that VIDIOC_S_CTRL was renumbered, but all distros still use old
VIDIOC_S_CTRL value (f.e. even xawtv-3.94 in Debian unstable still uses
old VIDIOC_S_CTRL definition).
So let's add this old VIDIOC_S_CTRL value (now named VIDIOC_S_CTRL_OLD) to
matroxfb's v4l handling.

[PATCH] Remove big-endian mode from matroxfb
One of the PowerPC developers, Kostas Georgiou, pointed out to me
discussion back from 2001 that they would prefer little endian mode as
majority of users runs XF4.x and not Xpmac. And apparently nobody runs
Xpmac now, so we can safely remove big-endian mode from matroxfb
completely.
So let's simplify matroxfb a bit:
Accelerator and ILOAD fifo is now always in little endian mode. This is
what XFree does. Due to this change all #ifdefs based on endianness was
removed from driver - except one which selects framebuffer endinaness (but
there is no code in matroxfb which writes to framebuffer directly).
It seems that while I was not looking m68k got ioremap, and all
architectures now offer ioremap and ioremap_nocache. Let's kill code which
mapped ioremap_nocache to ioremap, and ioremap to bus_to_virt for
architectures which did not provide them.
And this also fixes small typo - M_C2CTL should be 0x3C10 and not 0x3E10.
Apparently Matrox notes about need to program this register during
initialization are not so important...

[PATCH] fbcon unimap fix
fbcon doesn't set a unimap at boot time, so special characters come out
wrongly.
This is the code sequence in take_over_console().
newcon->startup()
oldcon->deinit()
newcon->init()
The previous console driver (ie, vgacon), via its deinit method, may release
the unimap allocated by fbcon in fbcon_startup. This is the reason why
calling con_set_default_unimap() in fbcon_init() works, but not in
fbcon_startup().
Check if the default display has an allocated unimap, and if it has none,
call con_set_default_unimap(). And if the target display has no allocated
unimap, then call con_copy_unimap(), where the source unimap is from the
default display.

[PATCH] VGA console font problems on 2.6 kernel
From: Egbert Eich <eich@suse.de>
I would like to utilize kernel ioctls to save/restore console fonts
in VGA text mode when running X. So far the Xserver takes care of this
however there more and more problems with this:
1. On some platforms (IA64) we need to POST the BIOS before
we even have a chance to access the hardware ourselves.
This POSTing will usually undo any changes to the graphics
hardware that the kernel may have done.
2. More and more drivers fully rely on BIOS support however
the BIOS functions which could be used to save/restore
register settings may be broken so the only way of mode
save/restore is getting/setting the BIOS mode ID.
I've hacked up some code for X however I ran into two problems:
1. con_font_get() in linux/drivers/char/vt.c seems to be broken as
the font parameters (height, width, charcount) are never reported
back. Therefore this function seems to be pretty useless.
The fix is simple (please see below).
2. fb consoles seem to allow to install fonts per vt so that the user
can have a different font on every console. The text console driver
doesn't support this: the font is downloaded to the video card
and will be used for all systems. Still the vga_con driver stores
the font parameters per console with the effect that setting a
font with different parameters on one console will result in the
wron values when this font information is read back from another
console.
Appearantly this broken feature has been introduced in 2.6 as
in the 2.4 kernel the vga_con font information is stored in one
single global variable.
The IA64 platform at least still heavily relies on the VGA text console.
To be able to fix some VT switching issues with X on this platform I
need these two issues resolved.

[PATCH] fbdev: Add Tile Blitting support
Hopefully, this patch fixes one last major regression for one particular
driver, namely matroxfb. This drier has 2 versions, one for the kernel and
another as a '2.4 backport' patch.
This patch adds a tileblitting extension to fbcon. This extension, in
summary, is basically a forward-port of the 2.4 fbdev/fbcon framework to 2.6
but without the fbcon dependency. Tile blitting is similar to bitblit, except
that the basic unit is a tile (a bitmap of x-by-y dimensions). The display,
instead of being described in terms of pixels and scanlines, are described as
a region further subdivided into rectangular sections. In fbcon parlance, a
tile is a character.
Besides a possible fix for matroxfb, tileblitting can be advantageous for
hardware that supports some kind of fontcaching mechanism. Also, in the
unlikely chance that the console begins supporting multicolored fonts,
tileblitting is probably more optimal than bitblitting because bitblitting
will need to push more data through the bus.
To enable support for this extension, a driver needs to:
- enable CONFIG_FB_TILEBLITTING
- set FBINFO_MISC_TILEBLITTING in info->flags
- set the required function pointers in struct fb_tileops. The required
operations are:
- void (*fb_settile)(struct fb_info *info, struct fb_tilemap *map);
tells driver about the tile characteristics (dimensions, bitdepth) and
about the tilemap which is an array of bitmaps: display->fontdata
- void (*fb_tilecopy)(struct fb_info *info, struct fb_tilearea *area);
move a rectangular section of tiles (bmove)
- void (*fb_tilefill)(struct fb_info *info, struct fb_tilerect *rect);
fill a rectangular section with a tile (clear)
- void (*fb_tileblit)(struct fb_info *info, struct fb_tileblit *blit);
copy an array of tiles to a rectangular section (putcs)
- void (*fb_tilecursor)(struct fb_info *info, struct fb_tilecursor *cursor);
cursor function
Changes:
Addition of this extension necessitates cleanup of fbcon.c. The basic drawing
functions in fbcon are bmove, clear, putcs and cursor (the fbcon_* set). The
fbcon_* set are just wrappers to accel_* set. However, usage is not
consistent, some functions call the fbcon_* set, others call the accel_* set.
With this patch, a new fbcon-specific structure (struct fbcon_ops) is created.
Depending on the setting of the hardware, this struct contains pointers to
either the tileblitting set or the bitblitting set (formerly the accel_* set).
The tileblitting set is new in this patch.
The vast majority of functions in fbcon will need to only call the fbcon_*
set. In turn, it calls functions in struct fbcon_ops. Knowledge of the
blitting type is not required.
The accel_* set is renamed to bit_* and is moved into a separate file,
bitblit.c. The tile blitting set is in tileblit.c.
In my case at least, the cleanup did produce an unexpected but beneficial
side effect, a little more speedup. Not much, < 5%.
Petr, if you have comments, suggestions, or you think this is a bad idea,
let me know.

- add struct device *device to struct fb_info
- store struct device in framebuffer_alloc()
- for drivers not using framebuffer_alloc(), store the struct during

This patch fixes the 'fbcon=map:<option>" of fbcon. (This option has been

tty2 = fb1
tty3 = fb1
tty4 = fb0
(sequence repeats for the rest of the consoles)

Right now it is 140 bytes on 64-bit and 72 bytes on 32-bit. Thats just a

[PATCH] cfq-v2 I/O scheduler update
Here is the next incarnation of the CFQ io scheduler, so far known as
CFQ v2 locally. It attempts to address some of the limitations of the
original CFQ io scheduler (hence forth known as CFQ v1). Some of the
problems with CFQ v1 are:
- It does accounting for the lifetime of the cfq_queue, which is setup
and torn down for the time when a process has io in flight. For a fork
heavy work load (such as a kernel compile, for instance), new
processes can effectively starve io of running processes. This is in
part due to the fact that CFQ v1 gives preference to a new processes
to get better latency numbers. Removing that heuristic is not an
option exactly because of that.
- It makes no attempts to address inter-cfq_queue fairness.
- It makes no attempt to limit upper latency bound of a single request.
- It only provides per-tgid grouping. You need to change the source to
group on a different criteria.
- It uses a mempool for the cfq_queues. Theoretically this could
deadlock if io bound processes never exit.
- The may_queue() logic can be unfair since it fluctuates quickly, thus
leaving processes sleeping while new processes are allowed to allocate
a request.
CFQ v2 attempts to fix these issues. It uses the process io_context
logic to maintain a cfq_queue lifetime of the duration of the process
(and its io). This means we can now be a lot more clever in deciding
which process is allowed to queue or dispatch io to the device. The
cfq_io_context is per-process per-queue, this is an extension to what AS
currently does in that we truly do have a unique per-process identifier
for io grouping. Busy queues are sorted by service time used, sub sorted
by in_flight requests. Queues that have no io in flight are also
preferred at dispatch time.
Accounting is done on completion time of a request, or with a fixed cost
for tagged command queueing. Requests are fifo'ed like with deadline, to
make sure that a single request doesn't stay in the io scheduler for
ages.
Process grouping is selectable at runtime. I provide 4 grouping
criterias: process group, thread group id, user id, and group id.
As usual, settings are sysfs tweakable in /sys/block/<dev>/queue/iosched
axboe@apu:[.]s/block/hda/queue/iosched $ ls
back_seek_max fifo_batch_expire find_best_crq queued
back_seek_penalty fifo_expire_async key_type show_status
clear_elapsed fifo_expire_sync quantum tagged
In order, each of these settings control:
back_seek_max
back_seek_penalty:
Useful logic stolen from AS that allow small backwards seeks in
the io stream if we deem them useful. CFQ uses a strict
ascending elevator otherwise. _max controls the maximum allowed
backwards seek, defaulting to 16MiB. _penalty denotes how
expensive we account a backwards seek compared to a forward
seek. Default is 2, meaning it's twice as expensive.
clear_elapsed:
Really a debug switch, will go away in the future. It clears the
maximum values for completion and dispatch time, shown in
show_status.
fifo_batch_expire
fifo_batch_async
fifo_batch_sync:
The settings for the expiry fifo. batch_expire is how often we
allow the fifo expire to control which request to select.
Default is 125ms. _async is the deadline for async requests
(typically writes), _sync is the deadline for sync requests
(reads and sync writes). Defaults are, respectively, 5 seconds
and 0.5 seconds.
key_type:
The grouping key. Can be set to pgid, tgid, uid, or gid. The
current value is shown bracketed:
axboe@apu:[.]s/block/hda/queue/iosched $ cat key_type
[pgid] tgid uid gid
Default is tgid. To set, simply echo any of the 4 words into the
file.
quantum:
The amount of requests we select for dispatch when the driver
asks for work to do and the current pending list is empty.
Default is 4.
queued:
The minimum amount of requests a group is allowed to queue.
Default is 8.
show_status:
Debug output showing the current state of the queues.
tagged:
Set this to 1 if the device is using tagged command queueing.
This cannot be reliably detected by CFQ yet, since most drivers
don't use the block layer (well it could, by looking at number
of requests being between dispatch and completion. but not
completely reliably). Default is 0.
The patch is a little big, but works reliably here on my laptop. There
are a number of other changes and fixes in there (like converting to
hlist for hashes). The code is commented a lot better, CFQ v1 has
basically no comments (reflecting that it was writting in one go, no
touched or tuned much since then). This is of course only done to
increase the AAF, akpm acceptance factor. Since I'm on the road, I
cannot provide any really good numbers of CFQ v1 compared to v2, maybe
someone will help me out there.

[PATCH] switchable and modular io schedulers
This patch modularizes the io schedulers completely, allowing them to be
modular. Additionally it enables online switching of io schedulers. See
also http://lwn.net/Articles/102593/ .
There's a scheduler file in the sysfs directory for the block device
queue:
axboe@router:/sys/block/hda/queue> ls
iosched max_sectors_kb read_ahead_kb
max_hw_sectors_kb nr_requests scheduler
If you list the contents of the file, it will show available schedulers
and the active one:
axboe@router:/sys/block/hda/queue> cat scheduler
[cfq]
Lets load a few more.
router:/sys/block/hda/queue # modprobe deadline-iosched
router:/sys/block/hda/queue # modprobe as-iosched
router:/sys/block/hda/queue # cat scheduler
[cfq] deadline anticipatory
Changing is done with
router:/sys/block/hda/queue # echo deadline > scheduler
router:/sys/block/hda/queue # cat scheduler

[PATCH] jbd wakeup fix
Processes can sleep in do_get_write_access(), waiting for buffers to be
removed from the BJ_Shadow state. We did this by doing a wake_up_buffer() in
the commit path and sleeping on the buffer in do_get_write_access().
With the filtered bit-level wakeup code this doesn't work properly any more -
the wake_up_buffer() accidentally wakes up tasks which are sleeping in
lock_buffer() as well. Those tasks now implicitly assume that the buffer came
unlocked. Net effect: Bogus I/O errors when reading journal blocks, because
the buffer isn't up to date yet. Hence the recently spate of journal_bmap()
failure reports.
The patch creates a new jbd-private BH flag purely for this wakeup function.
So a wake_up_bit(..., BH_Unshadow) doesn't wake up someone who is waiting for
a wake_up_bit(BH_Lock).
JBD was the only user of wake_up_buffer(), so remove it altogether.

[PATCH] move waitqueue functions to kernel/wait.c
The following patch series consolidates the various instances of waitqueue
hashing to use a uniform structure and share the per-zone hashtable among all
waitqueue hashers. This is expected to increase the number of hashtable
buckets available for waiting on bh's and inodes and eliminate statically
allocated kernel data structures for greater node locality and reduced kernel
image size. Some attempt was made to look similar to Oleg Nesterov's
suggested API in order to provide some kind of credit for independent
invention of something very similar (the original versions of these patches
predated my public postings on the subject of filtered waitqueues).
These patches have the further benefit and intention of enabling aio to use
filtered wakeups by standardizing the data structure passed to wake functions
so that embedded waitqueue elements in aio structures may be succesfully
passed to the filtered wakeup wake functions, though this patch series doesn't
implement that particular functionality.
Successfully stress-tested on x86-64, and ia64 in recent prior versions.

[PATCH] TIOCCONS security
The ioctl TIOCCONS allows any user to redirect console output to another
tty. This allows anyone to suppress messages to the console at will.
AFAIK nowadays not many programs write to /dev/console, except for start
scripts and the kernel (printk() above console log level).
Still, I believe that administrators and operators would not like any user
to be able to hijack messages that were written to the console.
The only user of TIOCCONS that I am aware of is bootlogd/blogd, which runs
as root. Please comment if there are other users.
Is there any reason why normal users should be able to use TIOCCONS?
Otherwise I would suggest to restrict access to root (CAP_SYS_ADMIN), e.g.
with this patch.

[PATCH] kallsyms data size reduction / lookup speedup
This patch is an improvement over my first kallsyms speedup patch posted about
2 weeks ago.
It changes scripts/kallsyms as to produce a different format for
kallsyms_names and extra data to speedup lookups. The compression algorithm
is quite simple: it uses all the char codes not actually used in symbols to
build a lookup table that translates these codes into small strings. For
instance, in my test runs the code 0xFE was being translated into "acpi_"
giving a 4 byte save on every translation.
The advantage of this algorithm is that to translate a symbol we only require
information that is stored on that symbol position, and never need to go back
on the compressed stream to get information from other symbols.
To give an idea about the benefits of this algorithm here are some benchmark
results on a P4 2.8GHz with a symbol table with 10000 entries:
kallsyms_lookup average time:
vanilla 1346.0 us
speedup 14.4 us
with this patch 0.5 us
total data produced by scripts/kallsyms:
uncompressed 169 Kb
vanilla 134 Kb
with this patch 91 Kb
(speedup was my latest patch, that only changed the way kallsyms_lookup worked
and not the data format)
I removed a cond_resched() from the proc/kallsyms handling code path, because
using stem compression, if the current position went backwards, the hole
stream would be uncompressed up to the current position. It seemed that by
removing this loop it would be safe to remove the conditional reschedule
altogether.
There is just one catch with this patch: the time it takes to compile the
kernel goes up just a bit (about 0.8s on a P4 2.8GHz with defconfig). If this
delay is not acceptable I can change the compression algorithm so that it can
use the previous table (calculating a new table is what consumes most of the
time, and not doing the actual compression) and check to see if it obtains a
similar compression ratio. If it does, then this is a sign that the symbol
patterns haven't changed that much and this table is still good to use. This
would not only cut the time down to half on any compilation (because of the 2
pass symbol build method), but in frequent cases where a developer is
compiling a single file and linking everything over and over again, the table
optimization process would never run.
I'm CC'ing Brent Casavant on this email, because last june he sent a patch
trying a different approach that used a 32 entry symbol cache, because there
was a problem with the time "top" took to read "proc/<pid>/wchan". I was
hopping he would be willing to test this patch and comment on the results.

[PATCH] Create nodemask_t
The idea behind this patch is to create a nodemask_t as a node analog of
cpumask_t. As NUMA machines become more common, the need for a standard,
cross-platform bitmap of both online & possible nodes becomes more
apparent. We believe we've worked out most of the kinks of the variable
length bitmap types with the recent cpumask_t patches. Nodemasks are also
currently far less widespread than cpumasks. Further, inclusion at this
point in the kernel would mean consistency in node handling between 2.6 and
2.7.
Future goals would be to get rid of the 'numnodes' variable used to count
the number of online nodes, and replace with node_online_map. This would
allow arbitrary node numbering and facilitate node hotplugging.
(Nothing actually uses this yet, but several projects need it, and it does

[PATCH] cdrom: buffer sizing fix
The problem is that some drives fail the "GET CONFIGURATION" command when
asked to only return 8 bytes. This happens for example on my drive, which
is identified as:
hdc: HL-DT-ST DVD+RW GCA-4040N, ATAPI CD/DVD-ROM drive
Since the cdrom_mmc3_profile() function already allocates 32 bytes for the
reply buffer, this patch is enough to make the command succeed on my drive.

[PATCH] sched: fix SCHED_SMT & numa=fake=2 lockup
This patch fixes an interaction between the numa=fake=<domains> feature,
the domain setup code and cpu_siblings_map[]. The bug leads to a bootup
crash when using numa=fake=2 on a 2-way/4-way SMP+HT box.
When SCHED_SMT is turned on the domains-setup code relies on siblings not
spanning multiple domains (which makes perfect sense). But numa=fake=2
creates an assymetric 1101/0010 splitup between CPUs, which results in two
siblings being on different nodes.
The patch adds a check_siblings_map() function that checks the sibling maps
and fixes them up if they violate this rule. (it also prints a warning in
that case.)
The patch also turns SCHED_DOMAIN_DEBUG back on - had this been enabled
we'd have noticed this bug much earlier.

[PATCH] sched_domains: Make SD_NODE_INIT per-arch #2
Here's yet another version of a patch to implement per-arch SD_*_INITs.
This follows the same basic idea of my last patch, but
1) defines an arch-specific SD_NODE_INIT for the 4 NUMA arches (i386,
x86_64, IA64 & PPC64),
2) defines *default* SD_CPU_INIT & SD_SIBLING_INIT for *all* arches,
with the possibility of them being overridden by simply defining an
arch-specific version in include/asm/topology.h.
The motivation behind the third version of this patch is that Martin feels
that there should be no "default" NUMA initializer because NUMA
characteristics are *very* arch/platform specific, and hence a "default"
NUMA initializer can only lead to confusion. I agree with most of that,
but don't quite see as much harm in having a default as he does.
Nevertheless, to keep him quiet, I've run up this version of the patch.
Martin, please run this through your magic test suite and make sure I
didn't break anything trivial.

[PATCH] CPU Scheduler: fix potential error in runqueue nr_uninterruptible count
Problem:
In the function try_to_wake_up(), when the runqueue's nr_uninterruptible
field is decremented it's possible (on SMP systems) that the pointer no
longer points to the runqueue that the task being woken was on when it went
to sleep. This would cause the wrong runqueue's field to be decremented
and the correct one tp remain unchanged.
Fix:
Save a pointer to the old runqueue at the beginning of the function and use
it when decrementing nr_uninterruptible.

[PATCH] sched: fixes for ia64 domain setup
Still having some trouble with ia64 domain setup on the Altixes. Jesse
hasn't had much time to look into it, and I'm lacking an Altix, so I'm not
sure if this is right or not...
Anyway, it again does the right thing on the NUMAQ, and fixes some real
bugs, so can you include it please?
* Increase SD_NODES_PER_DOMAIN to 6 from 4 to better match Altix's
topology. A setting of 4 will include this node, the other one
in the brick, and the 2 nodes in the next closest brick, while 6
will catch 2 other bricks. Probably it could be increased even
more.
* Work correctly with sparse and not completely full node maps.
* Nasty typo fixed in find_next_best_node:
- val = node_distance(node, i);
+ val = node_distance(node, n);
* Ensure all nodes are themselves a member of their numa balancing
domain. This is more a precaution against creative implementations
of node_distance.. but it makes the setup easier to verify without
having to look at a table of node_distance's, which is possibly
generated at runtime.
So again, I'm not too sure if this will fix the Altix setup or not. But if
you do a release, it will surely be less broken than it was before.

[PATCH] sched: integrate cpu hotplug and sched domains
Register a cpu hotplug notifier which reinitializes the scheduler domains
hierarchy. The notifier temporarily attaches all running cpus to a "dummy"
domain (like we currently do during boot) to avoid balancing. It then calls
arch_init_sched_domains which rebuilds the "real" domains and reattaches the
cpus to them.
Also change __init attributes to __devinit where necessary.

Alterations from Nick Piggin:
* Detach all domains in CPU_UP|DOWN_PREPARE notifiers. Reinitialise and
reattach in CPU_ONLINE|DEAD|UP_CANCELED. This ensures the domains as
seen from the scheduler won't become out of synch with the cpu_online_map.
* This allows us to remove runtime cpu_online verifications. Do that.
* Dummy domains are __devinitdata.
* Remove the hackery in arch_init_sched_domains to work around the fact that
the domains used to work with cpu_possible maps, but node_to_cpumask returned
a cpu_online map.

[PATCH] sched: trivial sched changes
The following patches properly intergrate sched domains and cpu hotplug (using
Nathan's code), by having sched-domains *always* only represent online CPUs,
and having hotplug notifier to keep them up to date.
Then tackle Jesse's domain setup problem: the disjoint top-level domains were
completely broken. The group-list builder thingy simply can't handle distinct
sets of groups containing the same CPUs. The code is ugly and specific enough
that I'm re-introducing the arch overridable domains.
I doubt we'll get a proliferation of implementations, because the current
generic code can do the job for everyone but SGI. I'd rather take a look at
it again down the track if we need to rather than try to shoehorn this into
the generic code.
Nathan and I have tested the hotplug work. He's happy with it.
I've tested the disjoint domain stuff (copied it to i386 for the test), and it
does the right thing on the NUMAQ. I've asked Jesse to test it as well, but
it should be fine - maybe just help me out and run a test compile on ia64 ;)
This really gets sched domains into much better shape. Without further ado,
the patches.

resultant filesystem can be safely umounted, and checked via normal

[PATCH] ReiserFS: Cleanup access of journal (cosmetic)
This patch cleans up fs/reiserfs/journal.c such that repeated uses of
SB_JOURNAL(p_s_sb) are removed in favor of a local journal variable. The
compiler won't care, and it makes the code much easier to read.

[PATCH] m32r: fix sys_tas system call for m32r
This patch fixes a sys_tas system call for m32r.
- This patch fixes an Oops at sys_tas() in case CONFIG_SMP && CONFIG_PREEMPT.
> Unable to handle kernel paging request at virtual address XXXXXXXX
It is because a page fault happens at the spin_locked region in sys_tas()
and in_atomic() checks preempt_count, but spin_lock() already counts up
the preemt_count.

- sys_tas() is used for user-level mutual exclusion for the m32r,
which is prepared to implement a linuxthreads library.
The above problem may be happened in a program, which uses
pthread_mutex_lock(), calls sys_tas().
The current m32r instruction set has no user-level locking
functions for mutual exclusion.
# I hope it will be fixed in the future...
- This patch fixes the problem by using _raw_spin_lock() instead of
spin_lock(). spin_lock() increments up preemt_count, on the contrary,
_raw_sping_lock() does not.
# I think this fix is just a temporary work around, and
# it is preferable to be rewrite to make it simpler by using
# asm() function or something...

[PATCH] m32r: SIO driver
Here is a patch to support the M32R SIO (serial IO) driver.
This driver supports the M32R serial ports.
- Supports two types M32R serial interfaces; M32R_SIO and M32R_PLDSIO.
- With SMP safeness.
Currently the M32R_PLDSIO serial interface, which is implemented on a PLD
on the M3T-M32700UT evaluation board, has slightly different specification
from the integrated peripheral SIO (M32R_SIO). Now we can select them by
CONFIG_ option.
It is a serial-core based driver, based on drivers/serial/8250.c. Any
comments or suggestions will be appreciated.

[PATCH] Fix show_trace() in irq context with CONFIG_4KSTACKS
- valid_stack_ptr() erroneously assumes that stack always lives in
task_struct->thread_info.
- the main loop in show_trace() does not recalc ebp after stack
switching. With CONFIG_FRAME_POINTER every call to print_context_stack()
will produce the same output.
With this patch, show_trace() does not use task argument in the main loop.
Instead, it converts stack to thread_info* context, and passes it to
print_context_stack() and (implicitly) to valid_stack_ptr().
valid_stack_ptr() now does bounds checking against proper context.

[PATCH] ppc32: fix cpu voltage change delay
This patch fixes a problem where my new powerbook would sometimes hang or
crash when changing CPU speed. We had schedule_timeout(HZ/1000) in there,
intended to provide a delay of one millisecond. However, even with
HZ=1000, it was (I believe) only waiting for the next jiffy before
proceeding, which could be less than a millisecond. Changing the code to
use msleep, and specifying a time of 1 jiffy + 1ms has fixed the problem.
(When I looked at the msleep code, it appeared to me that msleep(1) with
HZ=1000 would sleep for between 0 and 1ms.)
Ben also asked me to remove the code that changes the AACK delay enable,
after looking in the Darwin sources and seeing that Darwin does not change
this in its corresponding code.

[PATCH] generic irq subsystem: core
The main goal of this patch is to consolidate all the different but still
fundamentally similar arch/*/kernel/irq.c code into the kernel/irq/ subsystem.
There are 4 new files in the kernel/irq/ directory:
- handle.c: core bits: __do_IRQ() and handle_IRQ_event(),
callable from arch-specific irq.c code.
- manage.c: the main driver apis
- spurious.c: the handling of buggy interrupt sources.
- autoprobe.c: probing of interrupts - older code but still in use.
- proc.c: /proc/irq/ code.
- internals.h for irq-core-internal interfaces not visible to drivers
nor arch PIC code.
An architecture enables the generic hardirq code by defining
CONFIG_GENERIC_HARDIRQS in its arch Kconfig. People doing this conversion
should check out the x86/x64/ppc/ppc64 patches for details - the conversion is
quite straightforward but every converted function (i.e. every function
removed from the arch irq.c) _must_ be matched to the generic version and if
there is any detail that the generic code should do it has to be added to the
generic code. All of the currently converted 4 architectures were converted
like that, and the generic code was extended/fixed along the way.
Other changes related to this patchset:
- clean up the irq include files (linux/irq.h, linux/interrupt.h,
linux/hardirq.h) and consolidate asm-*/[hard]irq.h. Note, to keep all
non-touched architectures in an untouched state this consolidation is
done carefully and strictly under CONFIG_GENERIC_HARDIRQS.
Once the consolidation is done we can do a couple of final cleanups
to reach the following logical splitup of 3 include files:
linux/interrupt.h: driver-visible APIs and details
linux/irq.h: core irq and arch-PIC code, internals
asm-*/irq.h: arch PIC and irq delivery details
the following include files will likely vanish:
linux/hardirq.h merges into linux/irq.h
asm-*/hardirq.h: merges into asm-*/irq.h
asm-*/hw_irq.h: merges into asm-*/irq.h
Christoph would like to do these once the current wave of
cleanups gets in.

Take a process P1 that spawns a thread T (aka. a clone with CLONE_FILES).
If P1 forks another process P2 (aka. not a clone) while T is blocked in a
open() that should return file descriptor FD, then FD will be unusable in
P2. This leads to strange behaviors in the context of P2: close(FD)
returns EBADF, while dup2(a_valid_fd, FD) returns EBUSY and of course FD is
never returned again by any syscall...

from truncation, and although tmpfs swizzles page_mapping(page) between tmpfs
inode address_space and swapper_space, there's sufficient stabilization while
here in __set_page_dirty_nobuffers that the mapping after we locked

mapping->tree_lock i.e. the lock we hold is the right one.

[PATCH] exec: fix posix-timers leak and pending signal loss
I've found some problems with exec and fixed them with this patch to
de_thread.
The second problem is that a multithreaded exec loses all pending signals.
This is violation of POSIX rules. But a moment's thought will show it's
also just not desireable: if you send a process a SIGTERM while it's in the
middle of calling exec, you expect either the original program in that
process or the new program being exec'd to handle that signal or be killed
by it. As it stands now, you can try to kill a process and have that
signal just evaporate if it's multithreaded and calls exec just then. I
really don't know what the rationale was behind the de_thread code that
allocates a new signal_struct. It doesn't make any sense now. The other
code there ensures that the old signal_struct is no longer shared. Except
for posix-timers, all the state there is stuff you want to keep. So my
changes just keep the old structs when they are no longer shared, and all
the right state is retained (after clearing out posix-timers).
The final bug is that the cumulative statistics of dead threads and dead
child processes are lost in the abandoned signal_struct. This is also
fixed by holding on to it instead of replacing it.

[PATCH] softirqs: fix latency of softirq processing
The attached patch fixes a local_bh_enable() buglet: we first enabled
softirqs then did we do local_softirq_pending() - often this is preemptible
code. So this task could be preempted and there's no guarantee that
softirq processing will occur (except the periodic timer tick).
The race window is small but existent. This could result in packet
processing latencies or timer expiration latencies - hard to detect and
annoying bugs.
The fix is to invoke softirqs with softirqs enabled but preemption still
disabled. Patch is against 2.6.9-rc2-mm1.

[PATCH] fix PTRACE_ATTACH race with real parent's wait calls
There is a race between PTRACE_ATTACH and the real parent calling wait.
For a moment, the task is put in PT_PTRACED but with its parent still
pointing to its real_parent. In this circumstance, if the real parent
calls wait without the WUNTRACED flag, he can see a stopped child status,
which wait should never return without WUNTRACED when the caller is not
using ptrace. Here it is not the caller that is using ptrace, but some
third party.
This patch avoids this race condition by adding the PT_ATTACHED flag to
distinguish a real parent from a ptrace_attach parent when PT_PTRACED is
set, and then having wait use this flag to confirm that things are in order
and not consider the child ptraced when its ->ptrace flags are set but its
parent links have not yet been switched. (ptrace_check_attach also uses it
similarly to rule out a possible race with a bogus ptrace call by the real
parent during ptrace_attach.)
While looking into this, I noticed that every arch's sys_execve has:
current->ptrace &= ~PT_DTRACE;
with no locking at all. So, if an exec happens in a race with
PTRACE_ATTACH, you could wind up with ->ptrace not having PT_PTRACED set
because this store clobbered it. That will cause later BUG hits because
the parent links indicate ptracedness but the flag is not set. The patch
corrects all the places I found to use task_lock around diddling ->ptrace
when it's possible to be racing with ptrace_attach. (The ptrace operation
code itself doesn't have this issue because it already excludes anyone else
being in ptrace_attach.)

[PATCH] make rlimit settings per-process instead of per-thread
POSIX specifies that the limit settings provided by getrlimit/setrlimit are
shared by the whole process, not specific to individual threads. This
patch changes the behavior of those calls to comply with POSIX.
I've moved the struct rlimit array from task_struct to signal_struct, as it
has the correct sharing properties. (This reduces kernel memory usage per
thread in multithreaded processes by around 100/200 bytes for 32/64
machines respectively.) I took a fairly minimal approach to the locking
issues with the newly shared struct rlimit array. It turns out that all
the code that is checking limits really just needs to look at one word at a
time (one rlim_cur field, usually). It's only the few places like
getrlimit itself (and fork), that require atomicity in accessing a whole
struct rlimit, so I just used a spin lock for them and no locking for most
of the checks. If it turns out that readers of struct rlimit need more
atomicity where they are now cheap, or less overhead where they are now
atomic (e.g. fork), then seqcount is certainly the right thing to use for
them instead of readers using the spin lock. Though it's in signal_struct,
I didn't use siglock since the access to rlimits never needs to disable
irqs and doesn't overlap with other siglock uses. Instead of adding
something new, I overloaded task_lock(task->group_leader) for this; it is
used for other things that are not likely to happen simultaneously with
limit tweaking. To me that seems preferable to adding a word, but it would
be trivial (and arguably cleaner) to add a separate lock for these users
(or e.g. just use seqlock, which adds two words but is optimal for readers).
Most of the changes here are just the trivial s/->rlim/->signal->rlim/.
I stumbled across what must be a long-standing bug, in reparent_to_init.
It does:
memcpy(current->rlim, init_task.rlim, sizeof(*(current->rlim)));
when surely it was intended to be:
memcpy(current->rlim, init_task.rlim, sizeof(current->rlim));
As rlim is an array, the * in the sizeof expression gets the size of the
first element, so this just changes the first limit (RLIMIT_CPU). This is
for kernel threads, where it's clear that resetting all the rlimits is what
you want. With that fixed, the setting of RLIMIT_FSIZE in nfsd is
superfluous since it will now already have been reset to RLIM_INFINITY.
The other subtlety is removing:
tsk->rlim[RLIMIT_CPU].rlim_cur = RLIM_INFINITY;
in exit_notify, which was to avoid a race signalling during self-reaping
exit. As the limit is now shared, a dying thread should not change it for
others. Instead, I avoid that race by checking current->state before the
RLIMIT_CPU check. (Adding one new conditional in that path is now required
one way or another, since if not for this check there would also be a new
race with self-reaping exit later on clearing current->signal that would
have to be checked for.)
The one loose end left by this patch is with process accounting.
do_acct_process temporarily resets the RLIMIT_FSIZE limit while writing the
accounting record. I left this as it was, but it is now changing a limit
that might be shared by other threads still running. I left this in a
dubious state because it seems to me that processing accounting may already
be more generally a dubious state when it comes to NPTL threads. I would
think you would want one record per process, with aggregate data about all
threads that ever lived in it, not a separate record for each thread.
I don't use process accounting myself, but if anyone is interested in
testing it out I could provide a patch to change it this way.
One final note, this is not 100% to POSIX compliance in regards to rlimits.
POSIX specifies that RLIMIT_CPU refers to a whole process in aggregate, not
to each individual thread. I will provide patches later on to achieve that
change, assuming this patch goes in first.

[PATCH] parport_pc superio chip fixes
This patch fixes some troubles that somebody reported me with the superio
chips.
In short rmmod parport_pc && cat /proc/iomem was good enough for crashing
the box hard on some machine (and hwscan --printer was doing just that).
The way the oops triggers is that iomem tries to vsprintf the p->name, but
the p->name was a static string in the module address (now unloaded).
The reason is that the superio chip scanning leaves up to two persistent
ranges claimed. But the second (legacy) pass has no way to notice the
resources are already reclaimed. Plus if the superio->io was different
than the "io" variable (the range to scan for superio chips) the "io" range
would generate a leak of the original "io" range too.
I simply make sure to always release the requested space during the superio
scan, and I make sure not to istantiate new ranges in the p->base that
would cause the later parport scan to fail too (plus leaving up to leaked
resources).
The previous code that was returning values and was leaving garbage in
there made no sense to me. My best guess (assuming I didn't misread it ;)
is that probably somebody added the request_region without realizing
they're pointing to the very same address that would be requested later
(and nobody does accesses on those ranges until later, so it was very safe
to claim it later).
Disclaimer: I don't have the specs of the winbond and smsc at hand, I just
guessed what they do from the code (nothing checks superio->io except
get_superio_dma get_superio_irq, which made the thing enough self
explainatory to fix it without specs)

[PATCH] add sys_setaltroot()
Add a new system call setaltroot(2).
Currently, using the altroot feature is accessible only via the
set_personality() system call. It is accessible to user space only if there
is more than one exec domain in the system. This patch allows using the
altroot feature on systems where there is only one exec domain.
It is possible to work around the issue by adding a dummy exec domain, but it
was rejected for not being very elegant.
If this feature is implemented in userspace, it adds a 16% overhead on a test
case which greps for a single word in the kernel source tree.

pcmcia_get_{first,next}_region are tricky: they're used

wrappers are needed (for the moment). However, match_region()

but wait:
while (list != NULL) {

(strcmp(handle->dev_info, list->dev_info) == 0)) {
*match = list->info;
return CS_SUCCESS;
}
list = list->info.next;
}
as ds.c's handle doesn't have INFO_MTD_CLIENT, the if always
succeeds -- allowing is to simplify it for ds.c. However, this
means we need special functions for ds.c. It's not too large,
fortunately.

pcmcia_lookup_bus is only called from ds.c, and doesn't need to know
about a handle -- just about the struct pcmcia_socket.

[PATCH] cciss: fixes for clustering
This patch changes our open specifically for clustering software. We must
allow root to access any volume or device with a LUN ID. We also modified
our revalidate function for this reason.
If a logical is reserved, we must register it with the OS with size=0. Then
the backup system can call BLKRRPART after breaking the reservation to
set the device to the correct size.
We also must register a controller with no logical volumes for the online
utilities to function. This is the way we've done it since the 2.2 kernel.
Which doesn't neccesarily make it right, but we have legacy apps to consider.

[PCMCIA] 06-Kconfig_PCMCIA.diff
After noting three things, namely
1.) CardBus cards work without ds a.k.a. pcmcia loaded,
2.) ds a.k.a pcmcia cannot be built as module if pcmcia_core is
built in, and
3.) some commenting in drivers/pcmcia/Kconfig was obsolete
[to use 32-bit cards, you don't need pcmcia-cs],
I wrote this patch which introduces more config options for fine-
grained tuning of what to built as what and what not to built. In
future, 16-bit-specific code in pcmcia_core may be surrounded by
CONFIG_PCMCIA. Also, I'll try to remove the dependency of
yenta_socket on cardbus.

[PCMCICA] 05-obsolete_parts_of_cs.diff
Some parts of cs.c are not used by any PCMCIA socket or card driver
or the PCMCIA subsystem itself. Mark them CONFIG_PCMCIA_OBSOLETE.
Also, define pcmcia_get_window static as it was supposed to be.
