Devices in board DTS files are usually searchable by multiple
compatible strings. In this case the 8540 based SoC should be
obtainable via the chipset [DB8540 & AB8540] name 'u8540' or
the board name 'ccu8540'. It's already possible to obtain the
Device Tree via its chipset name, this patch makes it possible

Commits:
"ARM: ux500: Add Device Tree nodes for the ux500 Crypt device"
"ARM: ux500: Add Device Tree nodes for the ux500 Hash device"
Added the crypto and hash devices conditionally, i.e. so as to
be turned on per-board by setting an "status" property on the
device from "disabled" to "okay" on each device.
This is wrong since this is an SoC feature, it is not board
dependent. It is the same ASIC under all circumstances and
functionality does not vary with board family.
This moves the enablement into the SoC file.

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.

We didn't have any fixes sent up for -rc2, so this is a slightly larger
batch. A bit all over the place platform-wise; OMAP, at91, marvell,
renesas, sunxi, ux500, etc.
I tried to summarize highlights but there isn't a whole lot to point
out. Lots of little things fixed all over. A couple of defconfig updates
due to new/changing options.

The recent changes overhauling fs/aio.c introduced a bug that results in
the kioctx not being freed when outstanding kiocbs are cancelled at
exit_aio() time. Specifically, a kiocb that is cancelled has its
completion events discarded by batch_complete_aio(), which then fails to
wake up the process stuck in free_ioctx(). Fix this by modifying the
wait_event() condition in free_ioctx() appropriately.
This patch was tested with the cancel operation in the thread based code
posted yesterday.

A panic can be caused by simply cat'ing /proc/<pid>/smaps while an
application has a VM_PFNMAP range. It happened in-house when a
benchmarker was trying to decipher the memory layout of his program.
/proc/<pid>/smaps and similar walks through a user page table should not
be looking at VM_PFNMAP areas.
Certain tests in walk_page_range() (specifically split_huge_page_pmd())
assume that all the mapped PFN's are backed with page structures. And
this is not usually true for VM_PFNMAP areas. This can result in panics
on kernel page faults when attempting to address those page structures.
There are a half dozen callers of walk_page_range() that walk through a
task's entire page table (as N. Horiguchi pointed out). So rather than
change all of them, this patch changes just walk_page_range() to ignore
VM_PFNMAP areas.
The logic of hugetlb_vma() is moved back into walk_page_range(), as we
want to test any vma in the range.
VM_PFNMAP areas are used by:
- graphics memory manager gpu/drm/drm_gem.c
- global reference unit sgi-gru/grufile.c
- sgi special memory char/mspec.c
- and probably several out-of-tree modules
