Subject[PATCH] KVM: SVM: use kvm_pat_valid instead of kvm_mtrr_valid
Date
Using kvm_pat_valid instead of kvm_mtrr_valid here is more appropriate. It
does the same thing as calling kvm_mtrr_valid here without two useless
check. MSR_IA32_CR_PAT is only related to PAT register but not the other
MTRR related registers.
