[PATCH resend 00/15] arm64 crypto roundup

[Ard Biesheuvel]

This is a repost of the arm64 crypto patches that I have posted to the LAKML
over the past months. They have now been verified on actual hardware
(Cortex-A57) so if there are no remaining issues I would like to propose them
for 3.16.

Ard Biesheuvel (15):
  asm-generic: allow generic unaligned access if the arch supports it
  arm64: add abstractions for FPSIMD state manipulation
  arm64: defer reloading a task's FPSIMD state to userland resume
  arm64: add support for kernel mode NEON in interrupt context
  arm64/crypto: SHA-1 using ARMv8 Crypto Extensions
  arm64/crypto: SHA-224/SHA-256 using ARMv8 Crypto Extensions
  arm64/crypto: GHASH secure hash using ARMv8 Crypto Extensions
  arm64/crypto: AES using ARMv8 Crypto Extensions
  arm64/crypto: AES in CCM mode using ARMv8 Crypto Extensions
  arm64: pull in <asm/simd.h> from asm-generic
  arm64/crypto: AES-ECB/CBC/CTR/XTS using ARMv8 NEON and Crypto
    Extensions
  arm64/crypto: add shared macro to test for NEED_RESCHED
  arm64/crypto: add voluntary preemption to Crypto Extensions SHA1
  arm64/crypto: add voluntary preemption to Crypto Extensions SHA2
  arm64/crypto: add voluntary preemption to Crypto Extensions GHASH
