Reverted the change to struct v4l2_pix_format. I completely missed that
this struct was used by existing ioctls so that changing it broke the ABI.
I will have to think of another way of setting the top/left coordinates

First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.
This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
getting them indirectly
Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
they don't need sched.h
b) sched.h stops being dependency for significant number of files:
on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
after patch it's only 3744 (-8.3%).

[WORKQUEUE]: cancel_delayed_work: use del_timer() instead of del_timer_sync()
commit: 071b638689
was wrong, it was merged by mistake after that.
From the changelog:
after this patch:
...
delayed_work_timer_fn->__queue_work() in progress.
The latter doesn't differ from the caller's POV,
it does make a difference if the caller calls flush_workqueue() after
cancel_delayed_work(), in that case flush_workqueue() can miss this
work_struct.

Strip __cpuinit[data] from Node <-> PXM routines and supporting data
structures. Also make pxm_to_node_map and node_to_pxm_map local to the

This fixes a bug triggered by the following conditions:
- boot on a machine with a SLIT table defined
- kernel is configured w/ CONFIG_HOTPLUG_CPU=n
- cat /sys/devices/system/node/node*/distance
This will cause an oops by calling into a freed memory section.
In particular, on x86_64, __node_distance calls node_to_pxm().

Currently we have a maze of configuration variables that determine the
maximum slab size. Worst of all it seems to vary between SLAB and SLUB.
So define a common maximum size for kmalloc. For conveniences sake we use
the maximum size ever supported which is 32 MB. We limit the maximum size
to a lower limit if MAX_ORDER does not allow such large allocations.
For many architectures this patch will have the effect of adding large
kmalloc sizes. x86_64 adds 5 new kmalloc sizes. So a small amount of
memory will be needed for these caches (contemporary SLAB has dynamically
sizeable node and cpu structure so the waste is less than in the past)
Most architectures will then be able to allocate object with sizes up to
MAX_ORDER. We have had repeated breakage (in fact whenever we doubled the
number of supported processors) on IA64 because one or the other struct
grew beyond what the slab allocators supported. This will avoid future
issues and f.e. avoid fixes for 2k and 4k cpu support.
CONFIG_LARGE_ALLOCS is no longer necessary so drop it.
It fixes sparc64 with SLAB.

I'm getting zillions of undefined references to __kmalloc_size_too_large on

into lots of compilation units.
It turns out that gcc just isn't smart enough to work out that
__builtin_contant_p(size)==true implies that __builtin_contant_p(index)==true.
So let's give it a bit of help.

There is no user of destructors left. There is no reason why we should keep
checking for destructors calls in the slab allocators.
The RFC for this patch was discussed at
http://marc.info/?l=linux-kernel&m=117882364330705&w=2
Destructors were mainly used for list management which required them to take a
spinlock. Taking a spinlock in a destructor is a bit risky since the slab
allocators may run the destructors anytime they decide a slab is no longer
needed.
Patch drops destructor support. Any attempt to use a destructor will BUG().

There are no actual implementations of fixup_bigphys_addr() in
arch/powerpc, and with a 64-bit aware ioremap() and so forth, it
should no longer be necessary. This patch removes the last dregs of
fixup_bigphys_addr() from arch/powerpc.
In fact, the only reason this hasn't caused link errors already is
that nobody must have tried using one of the small number of drivers
using io_remap_pfn_range() on one of the small number of platforms
which are 32-bit but define CONFIG_PHYS_64BIT. Nonetheless this fixes
