This patchset (on top of the previous cr0 patchset) brings lazy fpu to npt.
For the cases where guest and host cr0 match (the majority) it will disable
intercepts for cr0.ts once the guest fpu is loaded, so the guest can to its
own lazy fpu without trapping.
v2:
Refactored last patch into three independent patches; no code changes.
Avi Kivity (6):
KVM: Set cr0.et when the guest writes cr0
KVM: SVM: Fix SVM_CR0_SELECTIVE_MASK
KVM: SVM: Initialize fpu_active in init_vmcb()
KVM: SVM: Restore unconditional cr0 intercept under npt
KVM: SVM: Selective cr0 intercept
KVM: SVM: Lazy fpu with npt
