I've compile tested the patch, but not run tested it:
https://people.freebsd.org/~jmg/aesni.9stable.patch

Note that 9stable uses gcc by default and this patch required clang, so
make sure you set WITH_CLANG=YES WITH_CLANG_IS_CC=YES, otherwise it won't
compile...

This patch only required minor changes from my original patch to apply..
