Hi,

I have reviewed the KVM implementation and actually I have also 
implemented PKRS in QEMU's binary translation.  I'll send a patch and 
commit this one too, since it can be tested.

For QEMU you'll still have to post the KVM parts (getting/setting the 
PKRS MSR) since I don't have a way to test those.
