crypto: omap-sham - hmac calculation bug fix for sha1 base hash
This patch fixes 2 hmac inter-dependent bugs.
1. "omap-sham: hash-in-progress is stored in hw format" commit introduced
optimization where temporary hash had been stored in OMAP specific format
(big endian).
For SHA1 it is different to real hash format, which is little endian.
Final HMAC value was calculated using incorrect hash.
Because CONFIG_CRYPTO_MANAGER_TESTS was disabled this error remained
unnoticed. After enabling this option, bug has been found.
2. HMAC was calculated using temporrary hash value.
For a single-request updates, temporary hash was the final one and
HMAC result was correct. But in fact only the final hash had to be used.
All crypto tests for HMAC produces only single request and
could not catch the problem. This problem is fixed here.

crypto: picoxcell - fix possible status FIFO overflow
The SPAcc's have 2 equally sized FIFO's - a command FIFO and a status
FIFO. The command FIFO takes the requests that are to be performed and
the status FIFO reports the results. It is possible to get into the
situation where there are more free spaces in the command FIFO than the
status FIFO if we don't empty the status FIFO quickly enough resulting
in a possible overflow of the status FIFO. This can result in incorrect
status being reported in the status FIFO.
Make sure that when we are submitting requests the number of requests
that have been dispatched but not yet popped from the status FIFO does
not exceed the size of a single FIFO.

Add new SHA-1/256 module that never needs any fallback and just calls the
PadLock hardware instruction supported from VIA Nano processors to implement
the "update" and "final" function.
They are respectively named "sha1_alg_nano" and "sha256_alg_nano", and will

crypto: caam - de-CHIP-ify device tree compatibles
- all the integration parameters have been captured by the binding.
- the block name really uniquely identifies this hardware.
Some advocate putting SoC names everywhere in case software needs
to work around some chip-specific bug, but more precise SoC
information already exists in SVR, and board information already
exists in the top-level device tree node.
Note that sometimes the SoC name is a worse identifier than the
block version, as the block version can change between revisions
of the same SoC.
As a matter of historical reference, neither SEC versions 2.x
nor 3.x (driven by talitos) ever needed CHIP references.

The SEC4 is also known as the Cryptographic Accelerator

genirq: Expand generic show_interrupts()
Some archs want to print extra information for certain irq_chips which
is per irq and not per chip. Allow them to provide a chip callback to
print the chip name and the extra information.
PowerPC wants to print the LEVEL/EDGE type information. Make it configurable.

block: fix issue with calling blk_stop_queue() from the request_fn handler
When the queue work handler was converted to delayed work, the
stopping was inadvertently made sync as well. Change this back
to being async stop, using __cancel_delayed_work() instead of
cancel_delayed_work().

block: fix bug with inserting flush requests as sort/merge
With the introduction of the on-stack plugging, we would assume
that any request being inserted was a normal file system request.
As flush/fua requires a special insert mode, this caused problems.
Fix this up by checking for this in flush_plug_list() and use
the appropriate insert mechanism.
Big thanks goes to Markus Tripplesdorf for tirelessly testing
patches, and to Sergey Senozhatsky for helping find the real
issue.

futex: Fix WARN_ON() test for UP
An update of the futex code had a
WARN_ON(!spin_is_locked(q->lock_ptr))
But on UP, spin_is_locked() is always false, and will
trigger this warning, and even worse, it will exit the function
without doing the necessary work.
Converting this to a WARN_ON_SMP() fixes the problem.

perf, x86: Complain louder about BIOSen corrupting CPU/PMU state and continue
Eric Dumazet reported that hardware PMU events do not work on his
system, due to the BIOS corrupting PMU state:
Performance Events: PEBS fmt0+, Core2 events, Broken BIOS detected, using software events only.
[Firmware Bug]: the BIOS has corrupted hw-PMU resources (MSR 186 is 43003c)
Linus suggested that we continue in the face of such BIOS-induced CPU
state corruption:
http://lkml.org/lkml/2011/3/24/608
Such BIOSes will have to be fixed - Linux developers rely on a working and
fully capable PMU and the BIOS interfering with the CPU's PMU state is simply
not acceptable.
So this patch changes perf to continue when it detects such BIOS
interaction, some hardware events may be unreliable due to the BIOS
writing and re-writing them - there's not much the kernel can do
about that but to detect the corruption and report it.

route: Take the right src and dst addresses in ip_route_newports
When we set up the flow informations in ip_route_newports(), we take
the address informations from the the rt_key_src and rt_key_dst fields
of the rtable. They appear to be empty. So take the address
informations from rt_src and rt_dst instead. This issue was introduced
by commit 5e2b61f78411be25f0b84f97d5b5d312f184dfd1 ("ipv4: Remove

m68k: merge m68k and m68knommu arch directories
There is a lot of common code that could be shared between the m68k
and m68knommu arch branches. It makes sense to merge the two branches
into a single directory structure so that we can more easily share
that common code.
This is a brute force merge, based on a script from Stephen King
<sfking@fdwdc.com>, which was originally written by Arnd Bergmann
<arnd@arndb.de>.
> The script was inspired by the script Sam Ravnborg used to merge the
> includes from m68knommu. For those files common to both arches but
> differing in content, the m68k version of the file is renamed to
> <file>_mm.<ext> and the m68knommu version of the file is moved into the

On top of this file merge I have done a simplistic merge of m68k and
m68knommu Kconfig, which primarily attempts to keep existing options and
menus in place. Other than a handful of options being moved it produces
identical .config outputs on m68k and m68knommu targets I tested it on.
With this in place there is now quite a bit of scope for merge cleanups
in future patches.
