Pull branch 'for-rmk' of git://git.linaro.org/people/ardbiesheuvel/linux-arm into devel-stable

Comments from Ard Biesheuvel:

I have included two use cases that I have been using, XOR and RAID-6
checksumming. The former gets a 60% performance boost on the NEON, the
latter over 400%.

ARM: add support for kernel mode NEON

Adds kernel_neon_begin/end (renamed from kernel_vfp_begin/end in the
previous version to de-emphasize the VFP part as VFP code that needs
software assistance is not supported currently.)

Introduces <asm/neon.h> and the Kconfig symbol KERNEL_MODE_NEON. This
has been aligned with Catalin for arm64, so any NEON code that does
not use assembly but intrinsics or the GCC vectorizer (such as my
examples) can potentially be shared between arm and arm64 archs.

ARM: move VFP init to an earlier boot stage

This is needed so the NEON is enabled when the XOR and RAID-6 algo
boot time benchmarks are run.

ARM: be strict about FP exceptions in kernel mode

This adds a check to vfp_support_entry() to flag unsupported uses of
the NEON/VFP in kernel mode. FP exceptions (bounces) are flagged as
a bug, this is because of their potentially intermittent nature.
Exceptions caused by the fact that kernel_neon_begin has not been
called are just routed through the undef handler.

ARM: crypto: add NEON accelerated XOR implementation

This is the xor_blocks() implementation built with -ftree-vectorize,
60% faster than optimized ARM code. It calls in_interrupt() to check
whether the NEON flavor can be used: this should really not be
necessary, but due to xor_blocks'squite generic nature, there is no
telling how exactly people may be using it in the real world.

lib/raid6: add ARM-NEON accelerated syndrome calculation

This is a port of the RAID-6 checksumming code in altivec.uc ported
to use NEON intrinsics. It is about 4x faster than the sequential
code.

ARM: be strict about FP exceptions in kernel mode

The support code in vfp_support_entry does not care whether the
exception that caused it to be invoked occurred in kernel mode or
in user mode. However, neither condition that could trigger this
exception (lazy restore and VFP bounce to support code) is
currently allowable in kernel mode.

In either case, print a message describing the condition before
letting the undefined instruction handler run its course and trigger
an oops.

In order to convert the Tegra MMC driver to using mmc_of_parse(), some

currently wrong but unused, and mmc_of_parse() causes that data to be
used for the first time.

ARM: Fix broken commit 0cc41e4a21d43 corrupting kernel messages

Commit 0cc41e4a21d43 (arch: remove direct definitions of KERN_<LEVEL>
uses) is broken - not enough thought was put into changing:

.asciz "string"

to

.asciz "string1" "string2"

The problem is that each string gets _separately_ NUL terminated, so
the result is a string containing:

"string1\0string2\0"

rather than:

"string1string2\0"

With our new printk levels, this ends up as - eg, KERN_DEBUG "string":

0x01 0x00 0x07 0x00 "string" 0x00

which produces lots of \x01 in the kernel log.
