The ret variable is not used in the function, so remove it and
directly return 0 at the end of the function.

The size parameter to btrfs_extend_item() is the number of bytes
to add to the item, not the size of the item after the operation
(like it is for btrfs_truncate_item(), there the size parameter
is not the number of bytes to take away, but the total size of
the item after truncation).
Fix it in the comment.

Two minor changes to comments:
* Remove reference to drivers/base/sys.c, removed in 0a962657.
* CPUs are now exported by sysfs via devices/system/cpu.

Due to the externs between the the comment and the trace_puts() macro.
This is fixed by moving the externs below the macro and keeping the
macro and comment directly together.

Merge with 49717cb ("kthread: Document ways of reducing OS jitter due

do_smart_update_queue() is called when an operation (semop,
semctl(SETVAL), semctl(SETALL), ...) modified the array. It must check
which of the sleeping tasks can proceed.
do_smart_update_queue() missed a few wakeups:
- if a sleeping complex op was completed, then all per-semaphore queues
must be scanned - not only those that were modified by *sops
- if a sleeping simple op proceeded, then the global queue must be
scanned again
And:
- the test for "|sops == NULL) before scanning the global queue is not
required: If the global queue is empty, then it doesn't need to be
scanned - regardless of the reason for calling do_smart_update_queue()
The patch is not optimized, i.e. even completing a wait-for-zero
operation causes a rescan. This is done to keep the patch as simple as
possible.

"This time we made the kernel- and interruption stack allocation
reentrant which fixed some strange kernel crashes (specifically
protection ID traps).
Furthemore this patchset fixes the interrupt stack in UP and SMP
configurations by using native locking instructions. And finally
usage of floating point calculations on parisc were disabled in the
MPILIB."

ARM: 7727/1: remove the .vm_mm value from gate_vma
ARM: 7723/1: crypto: sha1-armv4-large.S: fix SP handling
gdbserver inserting a breakpoint ends up calling copy_user_page() for a
code page. The generic version of which (non-aliasing config) didn't set
the PG_arch_1 bit hence update_mmu_cache() didn't sync dcache/icache for
corresponding dynamic loader code page - causing garbade to be executed.
So now aliasing versions of copy_user_highpage()/clear_page() are made
default. There is no significant overhead since all of special alias
handling code is compiled out for non-aliasing build
