Cover letter [PATCH 0/7] Enable MTRR/PAT support for KVM EPT(v2)

Hi, Avi

Here is the update patchset of enable MTRR/PAT support for KVM, and the last patch enabled EPT support. The shadow support would follow later, I am still doing some clean up work.

The change from v1 including bug fix and rename of GUEST_PAT support according to the newly published spec. For MTRR, I reuse host mtrr struct rather than duplicate the part of work. This is mostly for the preparation of shadow MTRR/PAT support.

I think last time you mentioned you have a draft patch for extra MSR save/restore on hand? If you are busy on other things, I can take it over.

Thanks!
