3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paolo Bonzini <pbonzini@xxxxxxxxxx>
commit 7cb060a91c0efc5ff94f83c6df3ed705e143cdb9 upstream.
KVM does not really do much with the PAT, so this went unnoticed for a
long time. It is exposed however if you try to do rdmsr on the PAT
register.
