[PATCH] selinux: change file_alloc_security to use GFP_KERNEL

This patch changes the SELinux file_alloc_security function to use
GFP_KERNEL rather than GFP_ATOMIC; the use of GFP_ATOMIC appears to be a
remnant of when this function was being called with the files_lock spinlock
held, and is no longer necessary.  Please apply.

Fix the SELinux mprotect checks on executable mappings so that they are not
re-applied when the mapping is already executable as well as cleaning up
the code.  This avoids a situation where e.g.  an application is prevented

[PATCH] slab: cache_estimate cleanup

Clean up cache_estimate() in mm/slab.c and improves the algorithm from O(n) to
O(1).  We first calculate the maximum number of objects a slab can hold after
struct slab and kmem_bufctl_t for each object has been given enough space.
After that, to respect alignment rules, we decrease the number of objects if
necessary.  As required padding is at most align-1 and memory of obj_size is
at least align, it is always enough to decrease number of objects by one.

The optimization was originally made by Balbir Singh with more improvements
from Steven Rostedt.  Manfred Spraul provider further modifications: no loop
at all for the off-slab case and added comments to explain the background.

The swapper address space operation are modified so that a regular

[PATCH] Reclaim slab during zone reclaim

If large amounts of zone memory are used by empty slabs then zone_reclaim
becomes uneffective.  This patch shakes the slab a bit.

The problem with this patch is that the slab reclaim is not containable to a
zone.  Thus slab reclaim may affect the whole system and be extremely slow.
This also means that we cannot determine how many pages were freed in this
zone.  Thus we need to go off node for at least one allocation.

The functionality is disabled by default.

We could modify the shrinkers to take a zone parameter but that would be quite
invasive.  Better ideas are welcome.

[PATCH] Zone reclaim: Allow modification of zone reclaim behavior

In some situations one may want zone_reclaim to behave differently.  For
example a process writing large amounts of memory will spew unto other nodes
to cache the writes if many pages in a zone become dirty.  This may impact the
performance of processes running on other nodes.

Allowing writes during reclaim puts a stop to that behavior and throttles the
process by restricting the pages to the local zone.

Similarly one may want to contain processes to local memory by enabling
regular swap behavior during zone_reclaim.  Off node memory allocation can
then be controlled through memory policies and cpusets.

[PATCH] zone_reclaim: configurable off node allocation period.

Currently the zone_reclaim code has a fixed window of 30 seconds of off node
allocations should a local zone have no unused pagecache pages left.  Reclaim
will be attempted again after this timeout period to avoid repeated useless
scans for memory.  This is also useful to established sufficiently large off
node allocation chunks to relieve the local node.

It may be beneficial to adjust that time period for some special situations.
For example if memory use was exceeding node capacity one may want to give up
for longer periods of time.  If memory spikes intermittendly then one may want
to shorten the time period to reduce the number of off node allocations.

This patch allows just that....

[PATCH] disable lost tick compensation before TSCs are synced

Avoid lost tick compensation early in boot before the TSCs are
synchronized.  Currently timekeeping is enabled before the TSCs are
synchronized, thus when the TSCs are synched (reset to zero), it appears
that a number of lost ticks have occurred.  This can cause premature expiry
of timers and in extreme cases can cause the soft lockup detection to fire.

[PATCH] sys_sched_getaffinity() & hotplug

Change sched_getaffinity() so that it returns a bitmap that indicates the
legally schedulable cpus that a task is allowed to run on.

Without this patch, if CONFIG_HOTPLUG_CPU is enabled, sched_getaffinity()
unconditionally returns (at least on IA64) a mask with NR_CPUS bits set.
This conveys no useful infornmation except for a kernel compile option.

This fixes a breakage we obseved running recent kernels. We have MPI jobs
that use sched_getaffinity() to determine where to place their threads.
Placing them on non-existant cpus is problematic :-)

[PATCH] Introduce __iowrite32_copy

that it does not guarantee write ordering, nor does it perform a memory

of access is required by some devices.

This change also introduces include/linux/io.h, at Andrew's suggestion.  It

[PATCH] hrtimers: fix posix-timer requeue race

From: Steven Rostedtrostedt@goodmis.org <rostedt@goodmis.org>

CPU0 expires a posix-timer and runs the callback function.  The signal is
queued.

After releasing the posix-timer lock and before returning to hrtimer_run_queue
CPU0 gets interrupted.  CPU1 delivers the queued signal and rearms the timer.
CPU0 comes back to hrtimer_run_queue and sets the timer state to expired.

The next modification of the timer can result in an oops, because the state
information is wrong.

Keep track of state = RUNNING and check if the state has been in the return
path of hrtimer_run_queue.  In case the state has been changed, ignore a
restart request and do not touch the state variable.

[PATCH] powerpc: enable irq's for platform functions.

Make the platform function interrupt functions actually work.  Calls
irq_enable() for the first in the list, and irq_disable() for the last.

Added *func to struct irq_client so the the user can pass just that to
pmf_unregister_irq_client().

[PATCH] ide-scsi: fix for IDE probe/remove ops changes

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to
find any devices to bind to.  It also triggers a message "Driver 'ide-scsi'
needs updating - please use bus_type methods" from the driver core.

The IDE core in 2.6.16-rc1 changed the location of an IDE driver's
->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t
struct not in the gen_driver sub-struct.  drivers/ide/ was updated for this
change but ide-scsi.c wasn't.  Hence the breakage.

This patch repairs ide-scsi and also eliminates the driver core warning.

[PATCH] sound/ppc/pmac.c typo

In 2.6.16-rc1 there is a small typo introduced by the 'Remove device_node
addrs/n_addr' changes which prevents my Powerbook G4 sound from working:

Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC).
snd: can't request rsrc  0 (Sound Control: 0x80000000:80004fff)
ALSA device list:
   No soundcards found.

The patch below fixes it.  Of course, the patch fixing the i2c issues
('i2c_smbus_write_i2c_block_data' patch) needs to be applied to in order
for the sound to completly work.

[PATCH] fuse: fix async read for legacy filesystems

While asynchronous reads mean a performance improvement in most cases, if
the filesystem assumed that reads are synchronous, then async reads may
degrade performance (filesystem may receive reads out of order, which can
confuse it's own readahead logic).

With sshfs a 1.5 to 4 times slowdown can be measured.

There's also a need for userspace filesystems to know whether asynchronous
reads are supported by the kernel or not.

To achive these, negotiate in the INIT request whether async reads will be
used and the maximum readahead value.  Update interface version to 7.6

If userspace uses a version earlier than 7.6, then disable async reads, and
set maximum readahead value to the maximum read size, as done in previous
versions.

An old patch designed to fix http://bugme.osdl.org/show_bug.cgi?id=4497,
