The patch splits easycap_delete(), which is in charge of
buffer deallocation, into smaller functions each
deallocating a specific kind of buffer.

When the device is probed, this driver allocates
audio buffers, and audio urbs.
This patch just split this into separate functions,
which helps clearing the currently gigantic probe function.

This parameter is now initialized at init_easycap(),

When the device is probed a driver struct is either
allocated or retrieved.
This operation is logically splitted in several functions.

The else statement is actually not required, as we can assign AS10X_CMD_ERROR

This used to be the default if the lock pointer was set, but now that lock is by
default only used for ioctl serialization. Those drivers that already used
core locking have this flag set explicitly, except for some drivers where
it was obvious that there was no need to serialize any file operations other
than ioctl.
The drivers that didn't need this flag were:
drivers/media/radio/dsbr100.c
drivers/media/radio/radio-isa.c
drivers/media/radio/radio-keene.c
drivers/media/radio/radio-miropcm20.c
drivers/media/radio/radio-mr800.c
drivers/media/radio/radio-tea5764.c
drivers/media/radio/radio-timb.c
drivers/media/video/vivi.c
sound/i2c/other/tea575x-tuner.c
The other drivers that use core locking and where it was not immediately
obvious that this flag wasn't needed were changed so that the flag is set
together with a comment that that driver needs work to avoid having to
set that flag. This will often involve taking the core lock in the fops
themselves.
Eventually this flag should go and it should not be used in new drivers.
There are a few reasons why we want to avoid core locking of non-ioctl
fops: in the case of mmap this can lead to a deadlock in rare situations
since when mmap is called the mmap_sem is held and it is possible for
other parts of the code to take that lock as well (copy_from_user()/copy_to_user()
perform a down_read(&mm->mmap_sem) when a page fault occurs).
It is very unlikely that that happens since the core lock serializes all
fops, but the kernel warns about it if lock validation is turned on.
For poll it is also undesirable to take the core lock as that can introduce
increased latency. The same is true for read/write.
While it was possible to make flags or something to turn on/off taking the
core lock for each file operation, in practice it is much simpler to just
not take it at all except for ioctl and leave it to the driver to take the
lock. There are only a handful fops compared to the zillion ioctls we have.
I also wanted to make it obvious which drivers still take the lock for all
fops, so that's why I chose to have drivers set it explicitly.

ZCACHE is a boolean in the Kconfig. When selected, it
should require that CRYPTO be builtin (=y).
Currently, ZCACHE=y and CRYPTO=m is a valid configuration
when it should not be.
This patch changes the zcache Kconfig to enforce this
dependency.

Instead now use ioremap. This is needed for 3.4 since this change
emerged in mainline during one of the previous rc cycles.
These solves the following compilation breaks:
drivers/staging/tidspbridge/core/tiomap3430.c:
In function ‘bridge_brd_start’:
drivers/staging/tidspbridge/core/tiomap3430.c:425:4:
error: implicit declaration of function ‘OMAP2_L4_IO_ADDRESS’
drivers/staging/tidspbridge/core/wdt.c: In function ‘dsp_wdt_init’:
drivers/staging/tidspbridge/core/wdt.c:56:2:
error: implicit declaration of function ‘OMAP2_L4_IO_ADDRESS’
For control registers a new function needs to be defined so we
can get rid of a layer violation, but that approach must be queued
for the next merge window.

release_firmware() and pointless comments
release_firmware() deals gracefullt with NULL pointers - it's
redundant to check for them before calling the function.
Also remove a few pointless comments - it's rather obvious from the
code that kfree() free's a buffer and that release_firmware() releases
firmware - comments just stating that add no value.

If, in __persistent_ram_init(), the call to
persistent_ram_buffer_init() fails or the call to
persistent_ram_init_ecc() fails then we fail to free the memory we
allocated to 'prz' with kzalloc() - thus leaking it.
To prevent the leaks I consolidated all error exits from the function
at a 'err:' label at the end and made all error cases jump to that
label where we can then make sure we always free 'prz'. This is safe
since all the situations where the code bails out happen before 'prz'
has been stored anywhere and although we'll do a redundant kfree(NULL)
call in the case of kzalloc() itself failing that's OK since kfree()
deals gracefully with NULL pointers and I felt it was more important
to keep all error exits at a single location than to avoid that one
harmless/redundant kfree() on a error path.

drivers/staging/vt6656/ioctl.c::private_ioctl()
If copy_to_user() fails in the WLAN_CMD_GET_NODE_LIST case of the
switch in drivers/staging/vt6656/ioctl.c::private_ioctl() we'll leak
the memory allocated to 'pNodeList'. Fix that by kfree'ing the memory
in the failure case.
Also remove a pointless cast (to type 'PSNodeList') of a kmalloc()
return value - kmalloc() returns a void pointer that is implicitly
converted, so there is no need for an explicit cast.

The task handoff notifier leaks task_struct since it never gets freed
after the callback returns NOTIFY_OK, which means it is responsible for
doing so.
It turns out the lowmemorykiller actually doesn't need this notifier at
all. It's used to prevent unnecessary killing by waiting for a thread
to exit as a result of lowmem_shrink(), however, it's possible to do
this in the same way the kernel oom killer works by setting TIF_MEMDIE
and avoid killing if we're still waiting for it to exit.
The kernel oom killer will already automatically set TIF_MEMDIE for
threads that are attempting to allocate memory that have a fatal signal.
The thread selected by lowmem_shrink() will have such a signal after the
lowmemorykiller sends it a SIGKILL, so this won't result in an
unnecessary use of memory reserves for the thread to exit.
This has the added benefit that we don't have to rely on
CONFIG_PROFILING to prevent needlessly killing tasks.

Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..
