Subject: [PATCH v2 0/4] crypto: Accelerated GCM for IPSec on ARM/arm64

This is a v2 as patch #1 was sent out in isolation a couple of days ago.

As it turns out, we can get ~10% speedup for RFC4106 on arm64
(Cortex-A53) by giving it the same treatment as ARM, i.e., avoid the
generic template and implement RFC4106 encapsulation directly in the
driver

Patch #3 adds larger key sizes to the tcrypt benchmark for RFC4106

Patch #4 fixes some prose on AEAD that turned out to be inaccurate.

Changes since v1:
- minor tweaks to the asm code in patch #1, one of which to fix a Clang
  build error

Note: patch #1 depends on the softirq context patches for kernel mode
NEON I sent out last week. More specifically, this implements a sync
AEAD that does not implement a !simd fallback, as AEADs are not callable
in hard IRQ context anyway.

Ard Biesheuvel (4):
  crypto: arm/ghash - implement fused AES/GHASH version of AES-GCM
  crypto: arm64/gcm - add RFC4106 support
  crypto: tcrypt - include larger key sizes in RFC4106 benchmark
  crypto: aead - fix inaccurate documentation
