All applied.  Thanks.

Series looks fine to me:

[PATCH 0/4] crypto: [sha] x86 SHA extension optimization of SHA1 and SHA256

[Tim Chen]

The new x86 SHA extensions provide new hardware accelerated instructions
for computing SHA1 and SHA256 hashes. This patch series provide the
assembly routines for SHA1 and SHA256 computation using these new
instructions to the kernel crypto library.  For 4K data blocks, we've
seen up to 3.6x speedup over existing SSSE3 enhanced routines in the
kernel crypto library on Broxton platform.

Refer to SHA extension programming guide in chapter 8.2 of the
Intel Architecture Instruction Set Extensions Programming reference.
