A couple of questions - why the usage of native_[read|write]_msr? I get the
__native_cpuid variant, but I am not sure I understand why you are using
the native_* variants. Especially as this code ends up being called on
Xen and lguest (at least on 64-bit) and probably should go through the
paravirt interfaces.
For Xen, the early microcode update should be done in the hypervisor launch.
However, if you have a more specific flow in mind please clarify. Keep
in mind Xen is largely a black box to non-Xen developers
(#include <stdrant.h>).

P.S. Since when is lguest 64-bit? Did I miss something?
