* simple_commit_write was only called by simple_write_end.
Open coding it makes it tiny bit less heavy on the arithmetic and
much more readable.* While at it use zero_user() for clearing a partial page.
* While at it add a docbook comment for simple_write_end.Signed-off-by: Boaz Harrosh

Alas, ->d_revalidate() can't rely on ->lookup() finishing what
it's started; if d_alloc() in do_lookup() fails, we are not going
to call ->lookup() at all.Signed-off-by: Al Viro

I create wrong asm code but none test shows that this part of code is wrong.
I am not convinces that were good idea to create asm optimized macros
for caches. The reason is that there is not optimization with previous code
that's why make sense to add old code and do some benchmarking which
functions are faster.Signed-off-by: Michal Simek

Traffic (tcp) doesnot start on a vlan interface when gro is enabled.
Even the tcp handshake was not taking place.
This is because, the eth_type_trans call before the netif_receive_skb
in napi_gro_finish() resets the skb->dev to napi->dev from the previously
set vlan netdev interface. This causes the ip_route_input to drop the
incoming packet considering it as a packet coming from a martian source.I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7.
With this fix, the traffic starts and the test runs fine on both vlan
and non-vlan interfaces.CC: Herbert Xu

The netif_wake_queue() is called correctly (i.e. only on !txfull
condition) from txdone routine. So Unconditional call to the
netif_wake_queue() here is wrong. This might cause calling of
start_xmit routine on txfull state and trigger BUG_ON.This bug does not happen when NAPI disabled. After txdone there
must be at least one free tx slot. But with NAPI, this is not
true anymore and the BUG_ON can hits on heavy load.In this driver NAPI was enabled on 2.6.33-rc1 so this is
regression from 2.6.32 kernel.Reported-by: Ralf Roesch

803bf5ec259941936262d10ecc84511b76a20921 ("fs/exec.c: restrict initial
stack space expansion to rlimit") attempts to limit the initial stack to
20*PAGE_SIZE. Unfortunately, in attempting ensure the stack is not
reduced in size, we ended up not changing the stack at all.This size reduction check is not necessary as the expand_stack call does
this already.This caused a regression in UML resulting in most guest processes being
killed.Signed-off-by: Michael Neuling

geode-mfgpt: restore previous behavior for selecting IRQ
The MFGPT IRQ used to be, in order of decreasing priority,
* IRQ supplied by the user as a boot-time parameter,
* IRQ previously set by the BIOS or another driver,
* default IRQ given at compile time.Return to this behavior, which got broken when splitting the
MFGPT/clocksource driver for 2.6.33-rc1.Signed-off-by: Jens Rottmann

This is retry of reverted 859ddf09743a8cc680af33f7259ccd0fd36bfe9d
("idr: fix a critical misallocation bug") which contained two bugs.* pa[idp->layers] should be cleared even if it's not used by
sub_alloc() because it's used by mark idr_mark_full().* The original condition check also assigned pa[l] to p which the new
code didn't do thus leaving p pointing at the wrong layer.Both problems have been fixed and the idr code has received good amount
testing using userland testing setup where simple bitmap allocator is
run parallel to verify the result of idr allocation.The bug this patch fixes is caused by sub_alloc() optimization path
bypassing out-of-room condition check and restarting allocation loop
with starting value higher than maximum allowed value. For detailed
description, please read commit message of 859ddf09.Signed-off-by: Tejun Heo

from processes under memcg(s) in oom. Then, it kills victim's child
first.It may kill a child in another cgroup and may not be any help for

This commit changes nouveau to construct PTEs which look very much like
the ones the binary driver creates.I presume that filling multiple PTEs identically with length flags and
the physical address of the start of a block of VRAM is a hint to the
memory controller that it need not perform additional page table lookups
for that range of addresses.Signed-off-by: Ben Skeggs
