Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm: x86: disable KVM for Voyager and friends KVM: VMX: Avoid rearranging switched guest msrs while they are loaded KVM: MMU: Fix race when instantiating a shadow pte KVM: Route irq 0 to vcpu 0 exclusively KVM: Avoid infinite-frequency local apic timer KVM: make MMU_DEBUG compile again KVM: move alloc_apic_access_page() outside of non-preemptable region KVM: SVM: fix Windows XP 64 bit installation crash KVM: remove the usage of the mmap_sem for the protection of the memory slots. KVM: emulate access to MSR_IA32_MCG_CTL KVM: Make the supported cpuid list a host property rather than a vm property KVM: Fix kvm_arch_vcpu_ioctl_set_sregs so that set_cr0 works properly KVM: SVM: set NM intercept when enabling CR0.TS in the guest KVM: SVM: Fix lazy FPU switching
