[PATCH] s390: SCLP device driver cleanup
From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>
sclp: core driver cleanup
Details:
- moved signal shutdown (quiesce) handling into a separate file
- cleanup of SCLP core driver:
. introduced driver states instead of bits
. introduced request retry count and retry limit
. sclp_add_request now returns an error code if a request couldn't be started
. introduced separate request structure for init_mask requests to simplify
code
. request timer is now manually checked in sclp_sync_wait because timer
interrupts are disabled in this context
. removed busy timer - request timer now handles both cases
. split up sclp_start_request into __sclp_start_request and sclp_process
queue
. removed sclp_error_message (unused)
. introduced sclp_check_handler function to split up initial init mask
test from standard init mask request processing
. introduced sclp_deactivate and sclp_reactivate for simplified reboot
event handling (and potential use in suspend/resume scenario)
. added protection against multiple concurrent init mask calls
- minor changes in SCLP core driver:
. updated comments
. renamed functions to be consistent with "function name starts with __ =>
needs lock"
. renamed internal functions for consistency reasons
. introduced inlined helper functions to simplify code
. moved EXPORT_SYMBOL definitions next to function definition
- changes in sclp console driver
. removed callback recursion to prevent stack overflow
- changes to CPI module
. added check for sclp_add_request return code
. changed printks to specify a message level
- changes to generic sclp tty layer
. removed timed buffer retry after error (timers may not work in some
situations)
. introduced return code for sclp_emit_buffer
- changes to sclp tty driver
. removed callback recursion
- changes to sclp vt220 driver
. removed callback recursion
. removed timed buffer retry after error
- modified sclp_init_mask to prevent problems with some compiler versions

[PATCH] uml: Fix setting of TIF_SIGPENDING
From: Bodo Stroesser <bstroesser@fujitsu-siemens.com>
My older patch, that sets TIF_SIGPENDING after an ptrace-interception
in syscall_trace() is wrong.
Some syscalls want to be called without any signal pending. If a signal
is pending on syscall-entry, they immediately return with -ERESTARTNOINTR.
Thus, on return to user, the pending signals can be processed and the
kernel will lower eip by 2 to have the syscall restarted after that.
Since my change sets TIF_SIGPENDING on the entry and exit interception,
stracing such a syscall looped! Try "strace ls" to see what happens.
Fix: set TIF_SIGPENDING on the exit interception only. This avoids the
loop and is enough for security.

[PATCH] uml: system call restart fixes
From: Bodo Stroesser
The implementation of sys_sigreturn() and sys_rt_sigreturn() in UML
must be changed.
This is necessary, since the return value of sys_*_sigreturn()
is the value of eax in the thread, that was interrupted by the
signal handler. If accidentaly eax contains -ERESTART_*, orig_eax
*must* be -1 to avoid syscall restart processing in kern_do_signal().
If orig_eax is >=0, eip might be lowered by 2, the process will fail.
In UML PT_REGS_SYSCALL_NR() or UPT_SYSCALL_NR() have to be used
instead of orig_eax.
While writing and testing an exploit for this, I saw that for most
interrupts, the syscall number is undefined. So even on a return from
interrupt a wrong syscall restart handling could happen.
And also: UML resumes a process with ptrace(PTRACE_SYSCALL/SYSEMU/SINGLESTEP
when a syscall in UML in SKAS mode has been processed. But since there
is a valid syscall number in the host's orig_eax, the host could do
a wrong syscall restarting if the syscall in UML was a sigreturn() returning
-ERESTART* To avoid this, in SKAS -1 should be written to regs.orig_eax
before restore_registers().

[PATCH] uml: kill host processes properly
This patch changes how UML kills ptraced processes in order to be more
correct in the presence of the ptrace changes in 2.6.9. It used to be that
ptrace stopped processes could simply be killed and they would go away. Now,
there's a new run state for ptraced processes which doesn't receive signals
until they are PTRACE_KILLed or PTRACE_CONTinued. So, this patch kills the
process, as usual, then PTRACE_KILL and PTRACE_CONT. This is done in
os_kill_ptrace_process() for use from skas mode, and in tracer() when it
sees a child process getting a SIGKILL.

[PATCH] uml: make vsyscall page into process page tables
From: Bodo Stroesser
To make the vsyscall-page available for copy_from_user() and
ptrace(), we should use kernel's "gate-vma" mechanism.
Therefore we need a valid page structure. To have this, one
page (or more) is allocated at boot time, the contents of the
vsyscall-page is copied into this page and the page's pte is
inserted in swapper's pagetables.
Now it will be copied into the pagetables of all processes.
Note: this alone doesn't work, since FIXADDR_USER_START and
FIXADDR_USER_END are not yet defined correctly. Also
access_ok_skas() does not yet grant read accesses to
pages not in the normal user area.
Risks:
Please check the first hunk! I don't know, whether this change is OK.
Maybe fixrange_init() is wrong anyway with 3-level-pagetables?
Here access_ok_skas() and FIXADDR_USER_XXXX are fixed.
Now everything should work fine, while the processes are
running. But if a process crashes, the vsyscall-page will
not be dumped.

[PATCH] uml: add elf vsyscall support
From: Bodo Stroesser
This is the first patch of a series of four.
These patches allow the use of sysenter-systemcalls in UML
if the host support sysenter.
Some facts have to be noted:
- the sysenter instruction does not save anything, not even the
return address. Thus the host-kernel builds a stackframe with an
fixed return address for the backjump to the vsyscall-page. All
kernels that support sysenter thus must have a vsyscall-page
- The hosts vsyscall-page is visible in all memory-contexts on the
host, even in those of the processes running on UML. This cannot
be changed.
So the best way to implement sysenter is to integrate the host's
vsyscall-page into UML, if available.
This patch creates a new source file containing an UML
initialization function. The function scans the Elf-auxiliary vector
that is prepared by the host for relevant information about:
- vsyscall elf-header
- vsyscall entry
- machine type (called "platform", e.g. "i586" or "i686")
- hardware capabilities
These informations are inserted into the Elf-auxiliary-vector that is
generated if an UML process calls "execXX()". If the information from
the auxiliray-vector is not complete, UML uses the previos default
values, with one exception: if the host has no vsyscall-page, UML now
does no longer insert AT_SYSINFO or AT_SYSINFO_EHDR elements. (I think,
that's better than writing dummies)
Since the host's vsyscall-page is always visible to UML processes, this
change is enough to let UML with an i686-compiled glibc use sysenter.
what's missing:
- is_syscall() in SKAS cannot access the code in the vsyscall-page via
copy_from_user(), thus singlesteppers still could break out. (Note:

[PATCH] uml: finish fixing run_helper failure path
Fix some bugs left in the failure path of run_helper by the previous patch:
it was missing one
os_close_file(fds[1])
which is conditional. To use the goto handling model, I set the fd to -1
if it's already closed (I don't want to check if keeping one more pipe-end
open is no problem).
Also do some cosmethic cleanup:
* "err" was what we returned even on success, so just use a neutral "ret".
* use tabs, not spaces.
* a little more comments.

[PATCH] uml: terminal cleanup
This is a major cleanup of the uml terminal drivers and console handling
(console as in "where the kernel messages go to", not as in "linux
virtual terminals"). The changes in detail:
(1) There is a new console driver calles "stderr" which (as the name
implies) simply dumps all kernel messages to stderr. That one
is registered very early in the boot process via console_initcall()
and will print every almost kernel message instantly: Both very
early in the boot process and very late in shutdown.
Note that this is not enabled by default, see below for details.
(2) Ditched the early-console-init hackery in stdio_console.c
(open_console(NULL) + related stuff) into the waste basket, not
needed any more as you can use the new stderr console driver to
get the kernel messages if your kernel crashes very early in the
boot process.
(3) Handle console initialitation for the uml stdio console and
virtual serial lines the normal way using the console->setup()
function. Now all kernel messages appear on your console device
once it is initialized without any dirty tricks.
(4) The (2) changes allow a number of further cleanups: As we don't
open a line without a tty_struct any more we can ...
* hook struct line into tty->driver_data
* pass around tty_struct instead of struct line everythere
* get rid of some trivial wrappers in ssl.c and stdio_console.c
because we can get struct line via tty_struct all the time now.
(5) Change the ordering in the arch/um/drivers/Makefile and thus
the link and initialization order to make sure the stdio console
and not the virtual serial line is the default console device.
(6) Fixed a number of Documentation/CodingStyle issues within the
code (not systematically, but usually just the places I was
touching anyway or where it bugged me while browsing the code
because it was hard to read).
Looks like that cleanup also fixed some strange tty issues I've seen in
the past (like console getty not responding to input sometimes, suse's
/sbin/blogd causing trouble).
Finally some usage notes for using the new stderr console:
If the stderr console is enabled, then it is the default console device
because it registeres very early in the boot process. But as it isn't
linked to a tty device this makes init unhappy, you'll see "can't open
initial console" error messages. Because you usually don't want that
the stderr console is turned off by default. That also maintains the
behavior that /dev/tty0 is the first console device registered and thus
the default console.
There are basically two useful use cases for the stderr console:
(1) Your kernel dies before the normal console device is initialized
and thus you don't see any messages. Just enable the stderr
console to see them by adding "stderr=1" to the kernel command line.
(2) You want to have the kernel messages on both stderr and your
console terminal device. Try something like this:
$ ./linux stderr=1 console=stderr console=ttyS0 ssl0=xterm
This example sets up the console on a virtual serial line and
pops up an xterm for that.

[PATCH] hostfs: uml: add some other pagecache methods
This is a follow-up to my previous "hostfs - uml: set .sendfile to
generic_file_sendfile" patch. I was asking whether other methods should have
been added, and comparing with ext3 I found some more ones.
However, I have not specific clues about them: I know they use the pagecache,
which relies on *page methods, which are defined by hostfs. So I think it
could work.
I have a doubt, whether hostfs needs the commented out method below:
static struct address_space_operations hostfs_aops = {
.writepage = hostfs_writepage,
.readpage = hostfs_readpage,
/* .set_page_dirty = __set_page_dirty_nobuffers, */
.prepare_write = hostfs_prepare_write,
.commit_write = hostfs_commit_write
};
Hostfs does not have a underlying device (and I have some rough idea that
buffers cache block devices data), so I wonder if that is needed or not.

[PATCH] uml: unregister signal handlers at reboot
From: Bodo Stroesser <bstroesser@fujitsu-siemens.com>
In most cases reboot failed on my system. After "Restarting system.", UML
exited without further messages. I found an SIGIO being processed by
sig_handler() resp. sig_handler_common_skas(). Don't know, why this exits,
maybe the context is no longer valid at this time. So, I changed the sequence
in the reboot part of main() to stop the timers and disable the fds before
unblocking the signals. Since this wasn't enough, I also added
set_handler(SIGXXX, SIG_IGN) calls to disable_timer() and
deactivate_all_fds(). Now reboot works fine in SKAS and it still works in TT.

[PATCH] uml: redo the signal delivery mechanism
This patch rips out the old signal delivery mechanism and replaces it with a
sane one.
Specifically, UML used to capture a host signal frame and use it as a template
for its own signal frames. This was a worthy idea, because it promised a
degree of architecture-independence for this part of UML, but impractical.
There are some environments, notably 32 bit emulation on a 64 bit box, where
you can't use the host signal frame as a template for your own. Plus, this
code is as complicated, even to someone who understands what it's doing, as
the standard fill-in-a-structure-and-write-it-to-the-stack. For everyone
else, it is incomprehensible.
So, this reimplements signal handling in the way that everyone else does. It
gives up on architecture independence, and moves this code into the
x86-specific stuff.

I've excluded the hottest part, i.e. the ubd symlink, while removing the

of people using the symlink rather than the preferred name. That part will be
merged later, I think.
Since now we have evidence of less and less users using devfs, we think that
it will not cause too much problems.

[PATCH] m32r: Make kernel headers for mutual exclusion
Here is a patch to update kernel headers for mutual exclusion,
atomic.h, bitops.h and semaphore.h of m32r.
This patch is for making these headers publishable to userland.
* include/asm-m32r/assembler.h (M32R_LOCK, M32R_UNLOCK):
Define M32R_LOCK and M32R_UNLOCK macros. For SMP configuration,
these macros are expanded to m32r's LOCK and UNLOCK instructions.
While, for UP configuration, these are simply expanded to m32r's
LD(load) and ST(store) instructions, respectively.
* include/asm-m32r/atomic.h, include/asm-m32r/bitops.h,
include/asm-m32r/semaphore.h:
- Change macros from LOAD and STORE to M32R_LOCK and M32R_UNLOCK,
respectively. It is because LOAD and STORE are too generic words.
- Change inline to __inline__.
Retrieve __inline__ modifiers for functions which are placed
outside of __KERNEL__ region in these headers, because those
functions might be included and used from ISO C program in
userland.
Currently, it seems that these headers are allowed to be included from
userland. Indeed, they are kernel stuff, but these headers provide
useful definitions and functions even for userland applications, I think.

[PATCH] typeof(dev->power.saved_state)
arch/arm/common/sa1111.c: In function `sa1111_suspend':
arch/arm/common/sa1111.c:816: warning: assignment from incompatible pointer type
This is a rather annoying, and IMHO pointless warning. First question:
what is the reasoning for using an array of unsigned bytes here? Are we
expecting to power manage devices which only have byte wide registers?
In reality, devices have half-word and word sized registers as well, which
means that dev->power.saved_state actually points to device specific data
(or even device driver specific data) for the device. As such, it makes
far more sense for this to be a 'void *'.
I'd rather not go around the ARM kernel tree adding pointless casts to 'u8
*' and back again because the wrong type for this was picked in the
structure definition, so here's a patch which changes this to void *.

[PATCH] x86_64: Add SRAT NUMA discovery to x86-64.
Add SRAT NUMA discovery to x86-64.
Previously the NUMA nodes on Opteron systems were directly read from the
hardware registers of the northbridge.
This version also supports reading it from the more generic ACPI SRAT table.
This allows to support NUMA on all kinds of systems and in general gives more
flexibility, but needs a bit of BIOS support.
This implementation was not done before because the SRAT specification had a
bad license from Microsoft that didn't allow to implement it on other OS. Now
that ACPI 3.0 is released and SRAT is part of it that isn't a concern anymore.
One side effect of this is that holes not described in SRAT (e.g. usually the
640K DOS and 4GB PCI memory holes) will not included in the nodes and won't
get mem_map entries allocated. This may have side effects for some drivers.
Some support for handling dual core AMD CPUs is included.
SLIT parsing is done in a later patch. Depends on earlier patches to split up
the ACPI boot parsing and to add better CMP support on x86-64.

[PATCH] x86_64: Split ACPI boot table parsing
Split ACPI boot table parsing
Split ACPI boot table parsing into two parts. First a acpi_boot_table_init()
call that initializes the basic ACPI table parsing machinery and discovers the
RSDP, and then another call to actually parse the various boot tables.
This is needed for a followon patch that implements SRAT support, because
nodes need to be set up before the other ACPI tables can be parsed.
On x86-64 I moved the early initialization very early because that is needed
for the SRAT parser.
On i386 it should be a nop.

careful to handle the NX bit correctly.
A previous slightly different version of this broke the X server on some RH
systems. I hope this version will be better, but if you have X server
problems please revert this one.

[PATCH] /proc/sys/kernel/bootloader_type
This patch exports to userspace the boot loader ID which has been exported
by (b)zImage boot loaders since boot protocol version 2.
It is needed so that update tools that update kernels from vendors know which
bootloader file they need to update; eg right now those tools do all kinds of
hairy heuristics to find out if it's grub or lilo or .. that installed the
kernel. Those heuristics are fragile in the presence of more than one
bootloader (which isn't that uncommon in OS upgrade situations).
Tested on i386 and x86-64; as far as I know those are the only
architectures which use zImage/bzImage format.

[PATCH] x86: remove data-header and code overlap in boot/setup.S
The setup.S data and code is not cleanly separated. The current space
reserved for setup header is not enough to fit the complete header. As a
result, part of the header (EDDBUF) will overwrite the initial code.
I haven't seen any negative impact of this bug. As, by the time the setup
code is overwritten, we would have finished executing it anyway. But, I
think it is better to separate the header and code and prevent this
data_overwriting_the_code condition.
The atatched patch adds some space in the header to fit all the data listed
in Documentation/i386/zero-page.txt for both i386 and x86_64 (and updates
zero-page.txt).

[PATCH] ppc64: tweaks to ppc64 cpu sysfs information
Currently the ppc64 sysfs code registers an entry for each possible cpu in
sysfs, rather than just online cpus. That makes sense, since the sysfs
entries are needed to control onlining of the cpus. However, this is done
even if CONFIG_HOTPLUG_CPU is not set, or if it is not a hotplug capable
(DLPAR) machine, which is a bit misleading. Secondly it also registers all
the other sysfs entries (mostly performance monitoring controls) on all
possible cpus, although they are quite meaningless on non-online cpus.
This patch alters the code to only register sysfs directories at boot for
cpus which are either online or could be onlined (cpu is possible, and
CONFIG_HOTPLUG_CPU and an lpar machine). Furthermore, the entries apart
from 'online' itself and 'physical_id' are only registered for online CPUs
(and deregistered again if a cpu goes offline).

[PATCH] ppc64: kprobes implementation
Kprobes (Kernel dynamic probes) is a lightweight mechanism for kernel
modules to insert probes into a running kernel, without the need to modify
the underlying source. The probe handlers can then be coded to log
relevent data at the probe point. More information on kprobes can be found
at:
http://www-124.ibm.com/developerworks/oss/linux/projects/kprobes/
Jprobes (or jumper probes) is a small infrastructure to access function
arguments. It can be used by defining a small stub with the same template
as the routine in kernel, within which the required parameters can be
logged.

[PATCH] PPC debug setcontext syscall implementation.
Add a debugging interface for PowerPC that allows signal handlers (or any
jump to a context, really) to perform debug functions. It allows the a
user program to turn on single-stepping, for instance, and the thread will
get a trap after executing the next instruction. It can also (on supported
PPC processors) turn on branch tracing and get a trap after the next branch
instruction is executed. This is useful for in-application debugging.
Note that you can enable single-stepping on x86 processors directly from
signal handlers. Newer x86 processors have the equivalent of a
branch-trace bit in the IA32_DEBUGCTL MSR and could have similar function
to this syscall. Most other processors could benefit from a similar
interface, except for ARM which is extraordinarily broken for debugging.
Future uses of this could be adding the ability to set the hardware
breakpoint registers from a signal handler.

[PATCH] Fix broken RST handling in ip_conntrack
Here's a patch that fixes a pretty serious bug introduced by a recent
"bugfix". The problem is that RST packets are ignored if they follow an
ACK packet, this means that the timeout of the connection isn't decreased,
so we get lots of old connections lingering around until the timeout
expires, the default timeout for state ESTABLISHED is 5 days.
This needs to go into -bk as soon as possible. The bug is present in
2.6.10 as well.

[PATCH] alloc_large_system_hash: NUMA interleaving
NUMA systems running current Linux kernels suffer from substantial inequities
in the amount of memory allocated from each NUMA node during boot. In
particular, several large hashes are allocated using alloc_bootmem, and as
such are allocated contiguously from a single node each.
This becomes a problem for certain workloads that are relatively common on
big-iron HPC NUMA systems. In particular, a number of MPI and OpenMP
applications which require nearly all available processors in the system and
nearly all the memory on each node run into difficulties. Due to the uneven
memory distribution onto a few nodes, any thread on those nodes will require a
portion of its memory be allocated from remote nodes. Any access to those
memory locations will be slower than local accesses, and thereby slows down
the effective computation rate for the affected CPUs/threads. This problem is
further amplified if the application is tightly synchronized between threads
(as is often the case), as they entire job can run only at the speed of the
slowest thread.
Additionally since these hashes are usually accessed by all CPUS in the
system, the NUMA network link on the node which hosts the hash experiences
disproportionate traffic levels, thereby reducing the memory bandwidth
available to that node's CPUs, and further penalizing performance of the
threads executed thereupon.
As such, it is desired to find a way to distribute these large hash
allocations more evenly across NUMA nodes. Fortunately current kernels do
perform allocation interleaving for vmalloc() during boot, which provides a
stepping stone to a solution.
This series of patches enables (but does not require) the kernel to allocate
several boot time hashes using vmalloc rather than alloc_bootmem, thereby
causing the hashes to be interleaved amongst NUMA nodes. In particular the
dentry cache, inode cache, TCP ehash, and TCP bhash have been changed to be
allocated in this manner. Due to the limited vmalloc space on architectures
such as i386, this behavior is turned on by default only for IA64 NUMA systems
(though there is no reason other interested architectures could not enable it
if desired). Non-IA64 and non-NUMA systems continue to use the existing
alloc_bootmem() allocation mechanism. A boot line parameter "hashdist" can be
set to override the default behavior.
The following two sets of example output show the uneven distribution just
after boot, using init=/bin/sh to eliminate as much non-kernel allocation as
possible.

While not perfectly even, we can see that there is a substantial improvement
in the spread of memory allocated by the kernel during boot. The remaining
uneveness may be due in part to further boot time allocations that could be
addressed in a similar manner, but some difference is due to the somewhat
special nature of node 0 during boot. However the uneveness has fallen to a
much more acceptable level (at least to a level that SGI isn't concerned
about).
The astute reader will also notice that in this example, with this patch
approximately 256 MB less memory was allocated during boot. This is due to
the size limits of a single vmalloc. More specifically, this is because the
automatically computed size of the TCP ehash exceeds the maximum size which a
single vmalloc can accomodate. However this is of little practical concern as
the vmalloc size limit simply reduces one ridiculously large allocation
(512MB) to a slightly less ridiculously large allocation (256MB). In practice
machines with large memory configurations are using the thash_entries setting
to limit the size of the TCP ehash _much_ lower than either of the
automatically computed values. Illustrative of the exceedingly large nature
of the automatically computed size, SGI currently recommends that customers
boot with thash_entries=2097152, which works out to a 32MB allocation. In any
case, setting hashdist=0 will allow for allocations in excess of vmalloc
limits, if so desired.
Other than the vmalloc limit, great care was taken to ensure that the size of
TCP hash allocations was not altered by this patch. Due to slightly different
computation techniques between the existing TCP code and
alloc_large_system_hash (which is now utilized), some of the magic constants
in the TCP hash allocation code were changed. On all sizes of system (128MB
through 64GB) that I had access to, the patched code preserves the previous
hash size, as long as the vmalloc limit (256MB on IA64) is not encountered.
There was concern that changing the TCP-related hashes to use vmalloc space
may adversely impact network performance. To this end the netperf set of
benchmarks was run. Some individual tests seemed to benefit slightly, some
seemed to be harmed slightly, but in all cases the average difference with and
without these patches was well within the variabilty I would see from run to
run.
The following is the overall netperf averages (30 10 second runs each) against
an older kernel with these same patches. These tests were run over loopback
as GigE results were so inconsistent run to run both with and without these
patches that they provided no meaningful comparison that I could discern. I
used the same kernel (IA64 generic) for each run, simply varying the new
"hashdist" boot parameter to turn on or off the new allocation behavior. In
all cases the thash_entries value was manually specified as discussed
previously to eliminate any variability that might result from that size
difference.
HP ZX1, hashdist=0
==================
TCP_RR = 19389
TCP_MAERTS = 6561
TCP_STREAM = 6590
TCP_CC = 9483
TCP_CRR = 8633
HP ZX1, hashdist=1
==================
TCP_RR = 19411
TCP_MAERTS = 6559
TCP_STREAM = 6584
TCP_CC = 9454
TCP_CRR = 8626
SGI Altix, hashdist=0
=====================
TCP_RR = 16871
TCP_MAERTS = 3925
TCP_STREAM = 4055
TCP_CC = 8438
TCP_CRR = 7750
SGI Altix, hashdist=1
=====================
TCP_RR = 17040
TCP_MAERTS = 3913
TCP_STREAM = 4044
TCP_CC = 8367
TCP_CRR = 7538
I believe the TCP_CC and TCP_CRR are the tests most sensitive to this
particular change. But again, I want to emphasize that even the differences
you see above are _well_ within the variability I saw from run to run of any
given test.
In addition, Jose Santos at IBM has run specSFS, which has been particularly
sensitive to TLB issues, against these patches and saw no performance
degredation (differences down in the noise).
This patch:
Modifies alloc_large_system_hash to enable the use of vmalloc to alleviate
boottime allocation imbalances on NUMA systems.
Due to limited vmalloc space on some architectures (i.e. x86), the use of
vmalloc is enabled by default only on NUMA IA64 kernels. There should be
no problem enabling this change for any other interested NUMA architecture.

[PATCH] collect page_states only from online cpus
I noticed the function __read_page_state() curiously high in a q-tools
profile of a write to a software raid0 device. Seems this is because we're
checking page_states for all possible cpus and we have NR_CPUS possible
when CONFIG_HOTPLUG_CPU=y. The default config for ia64 is now NR_CPUS=512,
so on a little 8-way box, this is a significant waste of time. The patch
below updates __read_page_state() and __get_page_state() to only count
page_state info for online cpus. To keep the stats consistent, the
page_alloc notifier is updated to move page_states off of the cpu going
offline. On my profile, this dropped __read_page_state() back into the
noise and boosted block write performance by 5% (as measured by spew -
http://spew.berlios.de).

[PATCH] mark_page_accessed() for read()s on non-page boundaries
When reading a (partial) page from disk using read(), the kernel only marks
the page as "accessed" if the read started at a page boundary. This means
that files that are accessed randomly at non-page boundaries (usually
database style files) will not be cached properly.
The patch below uses the readahead state instead. If a page is read(), it
is marked as "accessed" if the previous read() was for a different page,
whatever the offset in the page.
Testing results:
- Boot kernel with mem=128M
- create a testfile of size 8 MB on a partition. Unmount/mount.
- then generate about 10 MB/sec streaming writes
for i in `seq 1 1000`
do
dd if=/dev/zero of=junkfile.$i bs=1M count=10
sync
cat junkfile.$i > /dev/null
sleep 1
done
- use an application that reads 128 bytes 64000 times from a
random offset in the 64 MB testfile.

As expected, with the read-page-access.patch, the kernel keeps the 8 MB
testfile cached as expected, while without it, it doesn't.
So this is useful for workloads where one smallish (wrt RAM) file is read
randomly over and over again (like heavily used database indexes), while
other I/O is going on. Plain 2.6 caches those files poorly, if the app
uses plain read().

wherever there used to be a highmem_start_page comparison. Then, kill off
highmem_start_page.

[PATCH] mm: overcommit updates
Alan made overcommit mode 2 and it doesnt work at all. A process passing
the limit often does so at a moment of stack extension, and is killed by a
segfault, not better than being OOM-killed.
Another problem is that close to the edge no other processes can be
started, so that a sysadmin has problems logging in and investigating.
Below a patch that does 3 things:
(1) It reserves a reasonable amount of virtual stack space (amount
randomly chosen, no guarantees given) when the process is started, so
that the common utilities will not be killed by segfault on stack
extension.
(2) It reserves a reasonable amount of virtual memory for root, so that
root can do things when the system is out-of-memory
(3) It limits a single process to 97% of what is left, so that also an
ordinary user is able to use getty, login, bash, ps, kill and similar
things when one of her processes got out of control.
Since the current overcommit mode 2 is not really useful, I did not give
this a new number.
The patch is just for playing, not to be applied by Linus. But, Andrew, I
hope that you would be willing to put this in -mm so that people can
experiment. Of course it only does something if one sets overcommit mode
to 2.
The past month I have pressured people asking for feedback, and now have

[PATCH] Simplified readahead
With Ram Pai <linuxram@us.ibm.com>
- request size is now passed into page_cache_readahead. This allows the
removal of the size averaging code in the current readahead logic.
- readahead rampup is now faster (especially for larger request sizes)
- No longer "slow read path". Readahead is turn off at first random access,
turned back on at first sequential access.
- Code now handles thrashing, slowly reducing readahead window until
thrashing stops, or min size reached.
- Returned to old behavior where first access is assumed sequential only if
at offset 0.
- designed to handle larger (1M or above) window sizes efficiently

[PATCH] quota umount race fix
Fix possible races between umount and quota on/off.
Finally I decided to take a reference to vfsmount during vfs_quota_on() and
to drop it after the final cleanup in the vfs_quota_off(). This way we
should be all the time guarded against umount. This way was protected also
the old code which used filp_open() for opening quota files. I was also
thinking about other ways of protection but there would be always a window
(provided I don't want to play much with namespace locks) where
vfs_quota_on() could be called while umount() is in progress resulting in
the "Busy inodes after unmount" messages...
Get a reference to vfsmount during quotaon() so that we are guarded against
umount (as was the old code using filp_open()).

[PATCH] Fix of quota deadlock on pagelock: quota core
The four patches in this series fix deadlocks with quotas of pagelock (the
problem was lock inversion on PageLock and transaction start - quota code
needed to first start a transaction and then write the data which subsequently
needed acquisition of PageLock while the standard ordering - PageLock first
and transaction start later - was used e.g. by pdflush). They implement a
new way of quota access to disk: Every filesystem that would like to implement
quotas now has to provide quota_read() and quota_write() functions. These
functions must obey quota lock ordering (in particular they should not take
PageLock inside a transaction).
The first patch implements the changes in the quota core, the other three
patches implement needed functions in ext2, ext3 and reiserfs. The patch for
reiserfs also fixes several other lock inversion problems (similar as ext3
had) and implements the journaled quota functionality (which comes almost for
free after the locking fixes...).
The quota core patch makes quota support in other filesystems (except XFS
which implements everything on its own ;)) unfunctional (quotaon() will refuse
to turn on quotas on them). When the patches get reasonable wide testing and
it will seem that no major changes will be needed I can make fixes also for
the other filesystems (JFS, UDF, UFS).
This patch:
The patch implements the new way of quota io in the quota core. Every
filesystem wanting to support quotas has to provide functions quota_read()
and quota_write() obeying quota locking rules. As the writes and reads
bypass the pagecache there is some ugly stuff ensuring that userspace can
see all the data after quotaoff() (or Q_SYNC quotactl). In future I plan
to make quota files inaccessible from userspace (with the exception of
quotacheck(8) which will take care about the cache flushing and such stuff
itself) so that this synchronization stuff can be removed...
The rewrite of the quota core. Quota uses the filesystem read() and write()
functions no more to avoid possible deadlocks on PageLock. From now on every
filesystem supporting quotas must provide functions quota_read() and
quota_write() which obey the quota locking rules (e.g. they cannot acquire the
PageLock).

Make all architectures include the fallback header, except i386, because that

[PATCH] convert Linux to 4-level page tables
Extend the Linux MM to 4level page tables.
This is the core patch for mm/*, fs/*, include/linux/*
It breaks all architectures, which will be fixed in separate patches.
The conversion is quite straight forward. All the functions walking the page
table hierarchy have been changed to deal with another level at the top. The
additional level is called pml4.
mm/memory.c has changed a lot because it did most of the heavy lifting here.
Most of the changes here are extensions of the previous code.

[PATCH] replace clear_page_tables with clear_page_range
Rename clear_page_tables to clear_page_range. clear_page_range takes byte
ranges, and aggressively frees page table pages. Maybe useful to control
page table memory consumption on 4-level architectures (and even 3 level
ones).
Possible downsides are:
- flush_tlb_pgtables gets called more often (only a problem for sparc64
AFAIKS).
- the opportunistic "expand to fill PGDIR_SIZE hole" logic that ensures
something actually gets done under the old system is still in place.
This could sometimes make unmapping small regions more inefficient. There
are some other solutions to look at if this is the case though.

[ide] propagation of error code in PCI IDE setup
- Change the return value and the prototype of do_ide_setup_pci_device
Due to lack of appropriate return status code, the current clients of
do_ide_setup_pci_device() can not distinguish a failing invocation
from a successfull one. The patch modify do_ide_setup_pci_device() so
that it can propagate some of the errors from the lower layers.
- Make ide_setup_pci_device() aware of the change and propagate the news
itself. I only gave a quick sight to create_proc_ide_interfaces() (and
ide_remove_proc_entries()) but they do seem sane and it should not matter
if it fails or not.
- ide_setup_pci_devices(): mostly the same thing than ide_setup_pci_device().

[ARM PATCH] 2327/1: Thumb ld/st alignment fault fixups
Patch from George G. Davis
Adds support for Thumb ld/st alignment fault fixups via conversion of
Thumb ld/st instruction forms into equivalent ARM instructions and
reusing ARM alignment fault handler for Thumb instructions. This
implementation was inspired by and initially based on the algorithm
found in gdb/sim/arm/thumbemu.c.
I've backed out the silly 'T' suffix on PC in this version as requested
by RMK. At this point, I prefer to avoid making any of the other changes
discussed, e.g. dump_instr() for bad instruction cases, in order to get
the basic Thumb support change committed.

[PATCH] zatm fix
Repairs the breakage introduced in gcc4 fixes. Original had expanded
to
((struct zatm_dev *)(dev)->dev_data) = zatm_dev;
and that's what gcc4 had complained about (cast-as-lvalue). Proper fix is,
of course,
dev->dev_data = zatm_dev;
What we have in 2.6.10 is
dev = (struct atm_dev *)zatm_dev;
which doesn't cause complaints, but doesn't do anything good (leak + corruption
at the very least).

Patch from George G. Davis
Convert ARM proc files to use manifest constants defined in pgtable.h
and domain.h. This is a prelude to allow renumbering domains. The
domain renumbering is required to implement support for ARMv6 MMU
super sections where domain 0 is implied. Although this is technically
only required for ARMv6, it seemed reasonable to clean up all proc
files while here.
I did a test build with and without this patch applied and confirmed
that all proc file binaries are unchanged when this patch is applied.

[INFINIBAND]: Add IPoIB (IP-over-InfiniBand) driver
Add a driver that implements the (IPoIB) IP-over-InfiniBand protocol.
This is a network device driver of type ARPHRD_INFINIBAND (and
addr_len INFINIBAND_ALEN bytes).
The ARP/ND implementation for this driver is not completely
straightforward, because InfiniBand requires an additional path lookup
be performed (through an IB-specific mechanism) after a remote
hardware address has been resolved. We are very open to suggestions
of a better way to handle this than the current implementation.
Although IB has a special multicast group join mode intended to
support IP multicast routing (non member join), no means to identify
different multicast styles has yet been determined, so all joins by
the driver are currently full member joins. We are looking for
guidance in how to solve this.
The IPoIB protocol/encapsulation is described in the Internet-Drafts

[libata] verify ATAPI DMA for a given request is OK
After some testing, it seems that some PATA host adapter (ex. pdc20275) cannot
work reliably with specific request buffer sizes under ATAPI DMA mode.
Detailed test result:
4096, 2048, 1024, 512, 256: OK
384, 257, 255, 128, 96, 64, 32: failed (irq lost)
It seems multiple of 256 bytes are the safe ATAPI DMA buffer sizes to use.
Attached please find the patch to fix the pdc2027x ATAPI DMA problem.
Changes:
1. Add a callback function "check_atapi_dma()" to ata_port_operations such that libata core
can ask the driver: "Can this command be processed in ATAPI DMA mode safely? "
when the the command is received.
2. ATAPI DMA is off by default if the callback function is not provided by the driver
If the callback function is not provided by the driver, the ATAPI DMA should be as is.
The ATAPI DMA is already controlled by dev->flags.
BTW, the patch isolates the ATAPI DMA workaround to the pdc20275 driver itself,
not impacting libata core .

[libata] PIO error handling improvement
Tested burning CD-RW with libata-dev-2.6 and cdrecord:
1. ATAPI DMA mode - tested OK
2. ATAPI PIO mode - test failed when cdrecord finishes burning and issues MODE_SELECT to the device.
After checking the log, it showed that MODE_SELECT caused ata_pio_complete() to return error.
However, the error is not handled by ata_pio_task().
Attached please find the patch for ata_pio_task() error handling for your review.
(The patch is against the libata-dev-2.6 tree. )
Changes in the patch:
1. End the PIO task when PIO_ST_IDLE state is entered
2. End the PIO task after PIO_ST_TMOUT and PIO_ST_ERR state handled by ata_pio_error()
3. Remove the first "if" statement to handle the error condition returned from
ata_pio_block(), ata_pio_complete() and ata_pio_poll().
Change #2 is not so necessary since ata_pio_error() will put the cmd to PIO_ST_IDLE state
after the error condition is handled. The change just saves a function call to queue_work().
Tested OK on on my machine with pdc20275 and ASUS CD-RW drive.

[ARM PATCH] 2264/1: Move platform-specific code out of entry-armv.S
Patch from Deepak Saxena
This patch borrows from the uclinux source where they have moved
the per-platform code for get_irqnr_and_base, disable_fiq, and
irq_prio_table out of entry-armv.S. However, instead of putting the
macros in arch/arm/mach-$(MACHINE)/entry-header.S, we just have
it in the machine's incdir. This means we don't need the extra
complexity of creating symlink at build time. The patch also removes
the irq_prio_table as a requirement for all machines and makes it
specific to IOC/IOMD machines.
This patch drastically shrinks entry-armv.S and allows us to delete
and add machines without having to touch generic code (there were two
dead machines laying around in entry-armv.S).
Tested on IXP4xx and test-built for just about every defconfig.

[PATCH] quiet scsi ioctls warnings
SCSI ioctls can ask for a lot of memory and fail. We don't need to vomit
in the log file for this case. Again taken from the Red Hat minor
patches applied for FC3.

[PATCH] Paul Laufer CREDITS address update
Paul Laufer informed the list that he had changed address and his change
of address had been ignored so CREDITS was still wrong although other
files had been updated.

[PATCH] make microcode text less confusing
Red Hat got some confused customers due to this message. The confused
user case is when they update the BIOS and all of a sudden we have "no
suitable data" yet we did before. We (Arjan van de Ven) thus changed it
to "No new microcode" which is much much clearer.
