Virtualization - May 2007 - [PATCH 0/3] KVM paravirt_ops implementation

This is the start of a paravirt_ops implementation for KVM.  Most of it 
was done by Ingo Molnar, I just moved things around a bit.  I don't 
think there's a measurable performance benefit just yet but there are a 
few more optimizations that I think we can get in time for 2.6.23 that 
will be measurable.

Anthony Liguori

I think we should use the CPUID instruction (leaf 0x40000000) to detect
the hypervosor as we are doing in Xen.

Is that leaf reserved for such use by Intel?

What I can say is that we (including the H/W teams) reviewed it
internally.
