the problem is that with this the definitions were moved as well from libkvm.h
to kvm-x86.h which is private and not meant to be exported outside of libkvm
but those 3 functions are used by qemu-kvm.c as shown by :
/var/tmp/portage/app-emulation/kvm-51/work/kvm-51/qemu/qemu-kvm.c: In function
`load_regs':

the following patch moves them to a new public arch specific header for libkvm
named libkvm-x86.h and that needs to be installed in userspace as well but is
not completely independent and would had been as well ifdef inside libkvm.h
for simplicity.
Jerone or anyone else that is working in the architectural work care to
comment?

PS. tested in amd64
