FPSIMD register bank context switching and crypto algorithms
optimisations for arm64 from Ard Biesheuvel.
* tag 'for-3.16' of git://git.linaro.org/people/ard.biesheuvel/linux-arm:
arm64/crypto: AES-ECB/CBC/CTR/XTS using ARMv8 NEON and Crypto Extensions
arm64: pull in <asm/simd.h> from asm-generic
arm64/crypto: AES in CCM mode using ARMv8 Crypto Extensions
arm64/crypto: AES using ARMv8 Crypto Extensions
arm64/crypto: GHASH secure hash using ARMv8 Crypto Extensions
arm64/crypto: SHA-224/SHA-256 using ARMv8 Crypto Extensions
arm64/crypto: SHA-1 using ARMv8 Crypto Extensions
arm64: add support for kernel mode NEON in interrupt context
arm64: defer reloading a task's FPSIMD state to userland resume
arm64: add abstractions for FPSIMD state manipulation
asm-generic: allow generic unaligned access if the arch supports it
