[PATCH] fixes to ColdFire/5407 startup code
Correct the cache setup bits for the 5407. This enables the write
buffers properly (despite what the previous comment said). This
combined with fixed cache flushing code provides a nice performance
boost on the 5407.
Also fix the ROMfs setup to only move the ROMfs region if it is actually
configured.

[PATCH] mark ftape un-removable
From: Christoph Hellwig <hch@lst.de>
I've just grepped over the tree for reamining MOD_INC_USE_COUNT users, and
ftape is a really horrible one, it relies on MOD_{INC,DEV}_USE_COUNT in the
most horrible places + it's own bookkepping and the <= 2.4 may unload
hooks. And although I don't have the hardware I can guarantee it doesn't
work as expected.
So let's just remove the module_exit handler and mark it unremovable, if
someone wants to fix up ftape later it's fine with me, but it's a really
scary driver..

[PATCH] tuner driver fixes
From: Gerd Knorr <kraxel@bytesex.org>
"options tuner type=2" is just there for historical reasons and should
only be used/needed if the main driver doesn't allow to configure the
tuner type. I'm not sure whenever I can remove that altogether without
breaking anything. There are several users of the tuner module, some
outside the standard kernel tree ...
> > if (type < TUNERS) {
> > + t->type = type;
> > printk("tuner: type forced to %d (%s) [insmod]\n",
> > t->type,tuners[t->type].name);
> > set_type(client,type);
That is wrong, it will break in other corner cases, it may cause the
set_type() function not doing the initializations.
The prink can also be dropped because set_type does that too. The patch
below removes that. It also makes the kernel messages a bit more verbose
and adds support for two new tuners.

[PATCH] Fix sprintf modifiers in usr/gen_init_cpio.c for cygwin
From: Pragnesh Sampat <pragnesh.sampat@timesys.com>
The file initramfs_data.cpio is slightly different when generated on
cygwin, compared to linux, which causes the kernel to panic with the
message "no cpio magic" (See Documentation/early-userspace/README).
The problem in cpio generation is due to the difference in sprintf
modifiers on cygwin. The code uses "%08ZX" for strlen of a device node.
printf man pages discourages "Z" and has 'z' instead. Both of these are
not available on cygwin sprintf (at least some versions of cygwin). The
net result of all of this is that the generated file literally contains
"ZX" and then the strlen after that and messes up that 110 offset etc. The
file is 516 bytes long on the system that I tested and on linux it is 512
bytes.
The fix below just uses "%08X" for that field.

[PATCH] Inefficient TLB flush fix
From: Martin Hicks <mort@wildopensource.com>
This is a patch based on one that Jack Steiner sent to the ia64 list in
November. The original thread can be found at:
http://marc.theaimsgroup.com/?l=linux-ia64&m=106869606922555&w=2
I created the little wrapper function that was requested. I think the only
other arch, other than ia64, that doesn't at least include asm-generic/tlb.h
is arm.
Something appears broken in TLB flushing on IA64 (& possibly other
architectures). Functionally, it works but performance is bad on systems
with large cpu counts.
The result is that TLB flushing in exit_mmap() is frequently being done via
IPIs to all cpus rather than with a "ptc" instruction or with a new
context..

[PATCH] ide-tape: remove obsolete onstream support
From: Willem Riede <wrlk@riede.org>
The onstream drives, be they scsi, atapi, ieee1394 or usb, are supported by the
osst driver. When the drives were new, code was introduced in ide-tape
independently, but never really maintained since. There are issues with the
drives I found and dealt with in osst, that ide-tape doesn't address.
So this code in ide-tape is both redundant and imperfect. I assumed from
http://marc.theaimsgroup.com/?l=linux-kernel&m=107550547613846&w=2 that there
was buy in for removing it.
When this patch is applied, ide-tape will refuse to attach to an onstream DI
drive, and will write to syslog to use ide-scsi + osst instead.

[PATCH] Fix race in epoll_ctl(EPOLL_CTL_MOD)
From: Davide Libenzi <davidel@xmailserver.org>
A potential race can happen in epoll_ctl(EPOLL_CTL_MOD) where an event can
happen in between f_op->poll() and the lock on ep->lock (we cannot call
f_op->poll() inside a lock, and the f_op->poll() callback does not carry
any info at the current time - missing wake_up_info() already ;). In that
case the event would be removed. We can easily leave the event inside the
ready list and have the ep_send_events() logic do the job for us at later
time. (Thanks to david.lee@teracruz.com for reporting the thing, since it
shouldn't have been a nice one ;)

[PATCH] Fix __release_region() race
From: MAEDA Naoaki <maeda.naoaki@jp.fujitsu.com>
I am testing PCI hot-plug in 2.6.2 kernel, but sometimes a struct resource
tree in kernel/resource.c was broken if multiple hot-plug requests are
issued at the same time.
The reason is lots of drivers call release_region() on hot removal, and
__release_region(), which is invoked by release_region() macro, changes the
tree without holding a writer lock for resource_lock.
I think __release_region() must hold a writer lock as well as
__request_region() does.
A following patch fixes the issue in my environment.

[PATCH] off_t in nfsd_commit needs to be loff_t
From: Neil Brown <neilb@cse.unsw.edu.au>,
From: Miquel van Smoorenburg <miquels@cistron.nl>
While I was stress-testing NFS/XFS on 2.6.1/2.6.2-rc, I found that
sometimes my "dd" would exit with:
# dd if=/dev/zero bs=4096 > /mnt/file
dd: writing `standard output': Invalid argument
1100753+0 records in
1100752+0 records out
After adding some debug printk's to the server and client code and some
tcpdump-ing, I found that the NFSERR_INVAL was returned by nfsd_commit on
the server.
Turns out that the "offset" argument is off_t instead of loff_t. It isn't
used at all (unfortunately), but it _is_ checked for sanity, so that's
where the error came from.

[PATCH] drivers/char/vt possible race
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
I falled again on the crash in con_do_write() with driver->data beeing
NULL. It happens during boot, when userland is playing open/close games
with tty's, I was intentionally typing keys like mad during boot trying to
trigger another problem when this one poped up.
Looking at the code, I'm not sure how protected we are by the above (tty)
layer, paulus told me to not rely on anything like locking coming from
there, so I decided to extend the scope of the console semaphore one more
bit to cover races between calls to con_open, con_close and con_write.
Note that in con_do_write, I intentionally drop the semaphore to avoid
keeping it held when waiting on the local buffer, and I added some sanity
checks on tty->driver_data with some printk's in case we still have an open
race by the tty layer. At least, now, the couple vc_allocated &
tty->driver_data should be protected though.

[PATCH] /proc thread visibility fixes
From: Kingsley Cheung <kingsley@aurema.com>
Is is possible to examine the data of tasks currently existing in the system
which are not threads of the same thread group.
For example, the only task in the group where init is group leader is itself:
gen2 02:50:44 ~: ls /proc/1/task
1
However, I can then read the contents of 'stat' for any other task in the
system:
gen2 02:49:45 ~: cat /proc/1/task/$$/stat
1669 (bash) S 1668 1669 1669 34816 1730 256 1480 6479 12 4 8 5 5 17 15 0 1 0
+8065 3252224 451 4294967295 134512640 134955932 3221225104 3221222840
+4294960144 0 65536 3686404 1266761467 3222442959 0 0 17 0 0 0
I had a look at fs/proc/base.c and found that the 'lookup' functions for
these directories were checking that the task in question existed, but
overlooked the following:
1. In the function proc_pid_lookup, a check is required to ensure that
the task in question is a thread group leader. Without the check, any
task can have its data retrieved accordingly. Consider the following.
There is a multithreaded process 1777.
gen2 23:22:47 /proc/1777: ls task
1777 1778 1779 1780 1781 1782 1783 1784 1785 1786 1787 1788
However, I can read the stat file for its thread 1778 as follows:
gen2 23:22:50 /proc/1777: cat /proc/1778/stat
1778 (multithreadtest) T 1777 1777 1672 34816 1672 64 0 0 0 0 14 17 0 0 15 0 12 0 8871 24727552 104 4294967295 134512640 134515104 3221222496 1077365276 4294960144 0 0 0 0 3222479248 0 0 -1 1 0 0
But 1778 is not meant to show up in /proc/, as intended right?:
gen2 23:22:56 /proc/1777: ls /proc/
1 1365 1661 1793 881 dma kcore scsi

12 1658 17 807 devices irq net version
13 1660 1777 810 diskstats kallsyms partitions vmstat
2. The other part of the bug is in the function proc_task_lookup. Here
there needs to be a check that the task X is indeed a thread of the
thread group Y when we read /proc/<Y>/task/<X>.
Right now, this check does not exist, which allows for any existing
task to have its data read from another thread group directory. The
following reads the stat directory of my bash shell from the thread
group 1.
gen2 23:28:07 ~: cd /proc/1
gen2 23:28:10 /proc/1: ls

[PATCH] defer panic for too many items in boot parameter line
From: Werner Almesberger <werner@almesberger.net>
When passing too many unrecognized boot command line options (which become
arguments or environment variables), the 2.6 kernel panics (unlike 2.4,
which just ignores the extra items). Unfortunately, this happens before
the console is initialized, so all you get is a kernel that dies quickly,
for no apparent reason.
This is particularly irritating if using UML with
init=something wi th a lot of ar gu men t s
The patch below delays the panic until after console_init.
(akpm: I mainly added this in because we have other places where the
panic-later-on machinery is needed).

[PATCH] Fix printk level on non fatal MCEs

For various reasons non fatal Machine Checks can happen on Athlons (e.g.

They are not necessarily fatal and often only minor hardware glitches.
But what's annoying is that they're KERN_EMERG and pollute your console and
scare the user into writing confused kernel bug reports.
This patch just replaces the KERN_EMERGs with KERN_INFO for now. Longer
term I think it would be better to log this stuff into a separate log.

[PATCH] md: Allow partitioning of MD devices.
From: NeilBrown <neilb@cse.unsw.edu.au>
With this patch, md used two major numbers for arrays.
One Major is number 9 with name 'md' have unpartitioned md arrays, one per
minor number.
The other Major is allocated dynamically with name 'mdp' and had on array for
every 64 minors, allowing for upto 63 partitions.
The arrays under one major are completely separate from the arrays under the
other.
The preferred name for devices with the new major are of the form:
/dev/md/d1p3 # partion 3 of device 1 - minor 67
When a paritioned md device is assembled, the partitions are not recognised
until after the whole-array device is opened again. A future version of
mdadm will perform this open so that the need will be transparent.

[PATCH] md: Dynamically limit size of bio requests used for raid1 resync
From: NeilBrown <neilb@cse.unsw.edu.au>
Currently raid1 uses PAGE_SIZE read/write requests for resync, as it doesn't

has a measurable impact on rebuild speed (25M/s -> 60M/s)

[PATCH] md: Avoid unnecessary bio allocation during raid1 resync
From: NeilBrown <neilb@cse.unsw.edu.au>
For each resync request, we allocate a "r1_bio" which has a bio "master_bio"
attached that goes largely unused. We also allocate a read_bio which is
used. This patch removes the read_bio and just uses the master_bio instead.
This fixes a bug wherein bi_bdev of the master_bio wasn't being set, but was
being used.
We also introduce a new "sectors" field into the r1_bio as we can no-longer
rely in master_bio->bi_sectors.

[PATCH] kNFSd: Allow sunrpc/svc cache init function to modify the "key"
From: NeilBrown <neilb@cse.unsw.edu.au>
When adding a item to a sunrpc/svc cache that contains kmalloced data it is
usefully to move the malloced data out of the key object into the new cache
object rather than copying (as then we would need to cope with kmalloc
failure and such). This means modifying the original.
If the kmalloced data forms part of the key, then we must not move the data
out until after the key isn't needed any more. So this patch moves the
call to "INIT" on a new item (which fills in the key) to *after* the item
has been found (or not), and also makes sure we only call the HASH function
once.

[PATCH] Enable coredumps > 2GB
From: Andi Kleen <ak@muc.de>
Some x86-64 users were complaining that coredumps >2GB don't work.
This will enable large coredump for everybody. Apparently the 32bit
gdb/binutils cannot handle them, but I hear the binutils people are working
on fixing that. I doubt it will harm people - unreadable coredumps are not
worse than no coredump and it won't make any difference in space usage if
you get a 1.99GB or a 2.5GB coredump. So just enable it unconditionally.
If it should be really a problem for 32bit the rlimit defaults in
resource.h could be changed.
For file systems that don't support O_LARGEFILE you should just get an
truncated coredumps for big address spaces.

[PATCH] Limit hashtable sizes
From: "Chen, Kenneth W" <kenneth.w.chen@intel.com>
The issue of exceedingly large hash tables has been discussed on the
mailing list a while back, but seems to slip through the cracks.
What we found is it's not a problem for x86 (and most other
architectures) because __get_free_pages won't be able to get anything
beyond order MAX_ORDER-1 (10) which means at most those hash tables are
4MB each (assume 4K page size). However, on ia64, in order to support
larger hugeTLB page size, the MAX_ORDER is bumped up to 18, which now
means a 2GB upper limits enforced by the page allocator (assume 16K page
size). PPC64 is another example that bumps up MAX_ORDER.
Last time I checked, the tcp ehash table is taking a whooping (insane!)
2GB on one of our large machine. dentry and inode hash tables also take
considerable amount of memory.
Setting the size of these tables is difficult: they need to be constrained on
many-zone ia64 machines, but this could cause significant performance
problems when there are (for example) 100 million dentries in cache.
Large-memory machines which do not slice that memory up into huge numbers of
zones do not need to run the risk of this slowdown.
So the sizing algorithms remain essentially unchanged, and boot-time options
are provided which permit the tables to be scaled down.

[PATCH] Use CPU_UP_PREPARE properly
From: Rusty Russell <rusty@rustcorp.com.au>
The cpu hotplug code actually provides two notifiers: CPU_UP_PREPARE
which preceeds the online and can fail, and CPU_ONLINE which can't.
Current usage is only done at boot, so this distinction doesn't
matter, but it's a bad example to set. This also means that the
migration threads do not have to be higher priority than the
others, since they are ready to go before any CPU_ONLINE callbacks
are done.
This patch is experimental but fairly straight foward: I haven't been
able to test it since extracting it from the hotplug cpu code, so it's
possible I screwed something up.

[PATCH] kthread primitive
From: Rusty Russell <rusty@rustcorp.com.au>
These two patches provide the framework for stopping kernel threads to
allow hotplug CPU. This one just adds kthread.c and kthread.h, next
one uses it.
Most importantly, adds a Monty Python quote to the kernel.
Details:
The hotplug CPU code introduces two major problems:
1) Threads which previously never stopped (migration thread,
ksoftirqd, keventd) have to be stopped cleanly as CPUs go offline.
2) Threads which previously never had to be created now have
to be created when a CPU goes online.
Unfortunately, stopping a thread is fairly baroque, involving memory
barriers, a completion and spinning until the task is actually dead
(for example, complete_and_exit() must be used if inside a module).
There are also three problems in starting a thread:
1) Doing it from a random process context risks environment contamination:
better to do it from keventd to guarantee a clean environment, a-la
call_usermodehelper.
2) Getting the task struct without races is a hard: see kernel/sched.c
migration_call(), kernel/workqueue.c create_workqueue_thread().
3) There are races in starting a thread for a CPU which is not yet
online: migration thread does a complex dance at the moment for
a similar reason (there may be no migration thread to migrate us).
Place all this logic in some primitives to make life easier:
kthread_create() and kthread_stop(). These primitives require no
extra data-structures in the caller: they operate on normal "struct
task_struct"s.
Other changes:
- Expose keventd_up(), as keventd and migration threads will use kthread to
launch, and kthread normally uses workqueues and must recognize this case.
- Kthreads created at boot before "keventd" are spawned directly. However,
this means that they don't have all signals blocked, and hence can be
killed. The simplest solution is to always explicitly block all signals in
the kthread.
- Change over the migration threads, the workqueue threads and the
ksoftirqd threads to use kthread.
- module.c currently spawns threads directly to stop the machine, so a
module can be atomically tested for removal.
- Unfortunately, this means that the current task is manipulated (which
races with set_cpus_allowed, for example), and it can't set its priority
artificially high. Using a kernel thread can solve this cleanly, and with
kthread_run, it's simple.
- kthreads use keventd, so they inherit its cpus_allowed mask. Unset it.
All current users set it explicity anyway, but it's nice to fix.
- call_usermode_helper uses keventd, so the process created inherits its
cpus_allowed mask. Unset it.
- Prevent errors in boot when cpus_possible() contains a cpu which is not
online (ie. a cpu didn't come up). This doesn't happen on x86, since a
boot failure makes that CPU no longer possible (hacky, but it works).
- When the cpu fails to come up, some callbacks do kthread_stop(), which
doesn't work without keventd (which hasn't started yet). Call it directly,
and take care that it restores signal state (note: do_sigaction does a
flush on blocked signals, so we don't need to repeat it).

[PATCH] ACPI PM timer
From: Dominik Brodowski <linux@dominikbrodowski.de>,
John Stultz <johnstul@us.ibm.com>,
Dmitry Torokhov
Add the ACPI Powermanagement Timer as x86 kernel timing source. Unlike the
Time Stamp Counter, it is a reliable timing source which does not get
affected by aggressive powermanagement features like CPU frequency scaling.
Some ideas and some code are based on Arjan van de Ven's implementation for
2.4, and on R. Byron Moore's drivers/acpi/hardware/hwtimer.c.
We also replace the loop based delay_pmtmr with a TSC based delay_pmtmr,
which resolves a number of issues caused by the loop based delay. Unsynced
TSCs as well frequency changing TSCs will effect the length of __delay(), but
it seems this method works best.

[PATCH] loop.c doesn't fail init gracefully
From: BlaisorBlade <blaisorblade_spam@yahoo.it>
loop_init doesn't fail gracefully for two reasons:
1) If initialization of loop driver fails, we have an call to
devfs_add("loop") without any devfs_remove; I add that.
2) On lwn.net 2.6 kernel docs, Jonathan Corbet says: "If you are calling
add_disk() in your driver initialization routine, you should not fail
the initialization process after the first call."
So I make loop.c conform to this request by moving add_disk after all
memory allocations.

[PATCH] loop: BIO handling fix
From: Ben Slusky <sluskyb@paranoiacs.org>
One more patch --- this fixes a minor bio handling bug in the filebacked

I don't think you could actually see damage from this bug unless you
run device mapper on top of loop devices, but still this is the correct
behavior.

[PATCH] loop: remove the bio remapping capability
This patch removes the loop feature wherein we remap BIOs for block-backed
loop. So file-backed and block-backed loop are handled identically.
It cleans up the code a lot and fixes the low-on-memory lockups which
block-backed loop currently suffers.
What we lose is the journalling ordering guarantees which
exts-on-loop-on-blockdev had. But dm-crypt provides that.

[PATCH] Fix for PPP activ/passiv filter
From: Karsten Keil <kkeil@suse.de>
I found a bug in the PPPIOCSPASS PPPIOCSACTIVE IOCTL implementation in
kernel 2.5/2.6.
The current pppd code use a empty filter (uprog.len=0) to detach the filter
in the kernel, but this code was removed in 2.5.71 while fixing a compiler
warning.
Here the new patch, also with better limit checking.
The second patch check for flen == 0 in the filter check too, since later
in this code a filter[flen - 1] access is done, which is not so funny with
flen 0. Maybe it's not really needed anymore, since with the first patch
it would not longer called with flen=0.
paulus says:
It looks correct. Previously we had (and in 2.4 we still have)
if (uprog.len > 0 && uprog.len < 65536) {
...
which gave warnings since uprog.len is unsigned short. So someone
decided that both parts of the condition were redundant.

[PATCH] 2.6.3 pcnet32.c transmit hang fix
The transmit routine will stop interrupting and hang, causing the
tx_timeout routine to attempt to restart the device when the 32-bit
cur_tx counter wraps below dirty_tx. If the device had called
netif_stop_queue it will never call netif_wake_queue in the interrupt
routine (at least on an IA32 system) due to 32-bit wrap around arithmetic.
On my IA32 system 'dirty_tx > lp->cur_tx - TX_RING_SIZE + 2' would
always evaluate to false when dirty and cur_tx were less than 15,
preventing netif_wake_queue to be called.
By starting dirty_tx and cur_tx at 0xfffffff0 (to reduce test time) I
found that once cur_tx wrapped to zero, that transmitted buffers would
never be unmapped or freed because 'while (dirty_tx < lp->cur_tx) {'
was not true. cur_tx would keep incrementing (in start_xmit) but dirty_tx
would not (in pcnet32_interrupt), thus leaking skb's and pci map entries.
On PPC machines, the system would quickly run out of pci maps.
Fix tested on PPC and IA32.

[PATCH] Add support for HW accel. slaves
Now that David Miller accepted the first half of this set into 2.6,
I'm resending the last half to you for inclusion in netdev-2.6.

Change the bond interface to publish full VLAN hardware acceleration
offloading capabilities, and add capability in all xmit functions to
take special care for VLAN HW accel. tagged skb's that are going out
through a slave that is not offloading capable.
Add a mechanism to collect and save the VLAN Id's that have been
added on top of a bond interface, and propagate the register/add/kill
operations to the slaves.
Add blocking mechanism to prevent adding VLAN interfaces on top of a
bond that contains VLAN challenged slaves and to prevent adding VLAN
challenged slaves to a bond that already has VLAN interfaces on top
of it.
Add a section about VLAN to Documentation/networking/bonding.txt and
also correct some minor spelling/grammer errors.

[PATCH] Intel x86-64 support merge
This has all the x86-64 specific changes for Intel Prescott/Nocona

This patch is needed to boot an 64bit kernel on a 64-bit capable
Prescott machine.
The ugliest part is probably the swiotlb code. In fact the code for
that is not even included, but just reused from IA64. swiotlb
implements the PCI DMA API using bounce buffering. I don't like this at
all, but there was no other way to support non DAC capable hardware
(like IDE or USB) on machines with >3GB. Please redirect all flames for
that to the Intel chipset designers.
ChangeLog:
- Add Kconfig options for PSC
- Add support to reuse microcode driver from i386 (Suresh B Siddha)
- Try to optimize for the selected CPU
- Fix early CPUID check for Intel CPUs (Suresh B Siddha)
- Fix GDT to use the configured cache line size for padding
