JMG> Sounds like your tool chain doesn't have the necessary support for
JMG> AES-NI... Are you using gcc as cc? If so, do you have the necessary
JMG> tool chain work that I did in r255185 in your local tree?
I use clang from world based on r263296 (amd64) to build world and kernel
from same r263296 (amd64) (as indicated earlier).
JMG> Can you compile this test program?
Yes, of course. But kernel and modules are built with "-sysroot" option,
you know? And my "-sysroot" doesn't contains clang tree (and
"/usr/include/clang/3.4"), because it points to fresh world (in
OBJDIRPREFIX) and clang was not built for this world, I'm using "system"
one. It works for world, GENERIC kernel and all modules but aesni.
