Cover letter [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.
