Avi Kivity 8c7bb723b4 [PATCH] KVM: MMU: Ignore pcd, pwt, and pat bits on ptes 
The pcd, pwt, and pat bits on page table entries affect the cpu cache.  Since
the cache is a host resource, the guest should not be able to control it.
Moreover, the meaning of these bits changes depending on whether pat is
enabled or not.

So, force these bits to zero on shadow page table entries at all times.
