MFC question

[Allan Jude]

I was considering MFC'ing this commit to stable/10:

https://svnweb.freebsd.org/base?view=revision&revision=292782

It replaces the kernel implementation of SHA512 (sys/crypto/sha2/sha2.c)
with cperciva@'s version from libmd. In benchmarks it was 5-30% faster,
on x86_64 and arm/mips.

But, in head I ended up being asked to bump __FreeBSD_version because it
removes sys/crypto/sha2.h which was apparently used by a 3rd party
driver, and replaces it with sys/crypto/sha512.h

Does this kind of change mean it cannot be MFCd to stable/10? Or is it
ok to MFC it?
