Summary

Add support for hypervisor check on x86

Add ficl words for isvirtualized
and move ficl inb and outb words to ficl/x86/sysdep.c
so can be shared by i386 and amd64

Looks reasonably sane. Saw one magic number. Would like lua implementation, but won't block this based on that.

Magic number?

Yes, the same bare number shows up in sys/x86/x86/identcpu.c identify_hypervisor_cpuid_base() which refers to a vmware kb article
if I read that correctly 0x40000000 is the hypervisor identifier

I only reviewed defs.mk. Looks fine.

I know this is pre-existing (and in kmod.mk) but what is this? I don't see the point.

It's making path an absolute path. realpath $$path would do as well

Oh I was thinking zsh here which considers path == PATH. I see now.
