Thread-topic:	One question for CPUID for PV guest

Keir/Jean, I have one question for changeset 17524 "Guest CPUID
configuration" (The URL is
http://xenbits.xensource.com/staging/xen-unstable.hg?rev/18727843db60). 
This changeset  do CPUID caculation in libxc. My question is, why don't
we have such support for PV guest? Currently PV guest's CPUID
virtualization is hardcoded in emulate_forced_invalid_op(), is it
possible to do things like hvm domain?

Thanks
Yunhong Jiang
