[GIT PULL] arm64: second wave of arm64 fixes for 3.17

[Will Deacon]

Hello Linus,

Please can you pull these fixes for arm64? They address some issues found
by running smatch on the arch code (ignoring the false positives) and also
stop 32-bit Android from losing track of its stack.

There's one additional irq migration fix in the pipeline, but it came in
after I'd tagged and tested this set.

Thanks,

Will

arm64 fixes for -rc4

Another handful of arm64 fixes here:

  - A few fixes for real issues found by smatch (after Dan's talk at KS)
  - Revert the /proc/cpuinfo changes merged during the merge window.
    We've opened a can of worms here, so we need to find out where we
    stand before we change this interface.
  - Implement KSTK_ESP for compat tasks, otherwise 32-bit Android gets
    confused wondering where its [stack] has gone
  - Misc fixes (fpsimd context handling, crypto, ...)
