Hi,

I accidentally noticed that padlock engine is not included on AMD64
port (neither as module or built-in). Is there any reason it excluded
from it? The build currently fails because inline asm code is using
pushl, popl instructions in the code in via_padlock_cbc method, but
replacing them with pushf, popf seemingly fixes the build and padlock
attaches. Since VIA has x86-64 based CPUs and all of them has the
engine, probably it makes sense to include it?

Regards,
Andrius V
