Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"This set includes adding support for Neon acceleration of RAID6 XOR
code from Ard Biesheuvel, cache flushing and barrier updates from Will
Deacon, and a cleanup to the ARM debug code which reduces the amount
of code by about 500 lines.
A few other cleanups, such as constifying the machine descriptors
which already shouldn't be written to, cleaning up the printing of the
L2 cache size"
