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
