[GIT PULL] support for kernel mode NEON

[GIT PULL] support for kernel mode NEON

[Ard Biesheuvel]

Hello Russell,

If you feel the remaining issues with these patches have been
addressed, please find my pull request below.
Note that the RAID-6 syndrome calculation patch is not included here:
the code lives under linux/lib/raid6/ so I will propose it on the LKML
instead.

Regards,
Ard.

Hello Russell,

Please ignore this request for now, I think there is still a thing I
need to fix.
Will send a v2 first, and another pull request later.

Regards,
Ard.
