Merge branch 'kvm-updates/2.6.31' of git://git.kernel.org/pub/scm/virt/kvm/kvm
* 'kvm-updates/2.6.31' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (138 commits) KVM: Prevent overflow in largepages calculation KVM: Disable large pages on misaligned memory slots KVM: Add VT-x machine check support KVM: VMX: Rename rmode.active to rmode.vm86_active KVM: Move "exit due to NMI" handling into vmx_complete_interrupts() KVM: Disable CR8 intercept if tpr patching is active KVM: Do not migrate pending software interrupts. KVM: inject NMI after IRET from a previous NMI, not before. KVM: Always request IRQ/NMI window if an interrupt is pending KVM: Do not re-execute INTn instruction. KVM: skip_emulated_instruction() decode instruction if size is not known KVM: Remove irq_pending bitmap KVM: Do not allow interrupt injection from userspace if there is a pending event. KVM: Unprotect a page if #PF happens during NMI injection. KVM: s390: Verify memory in kvm run KVM: s390: Sanity check on validity intercept KVM: s390: Unlink vcpu on destroy - v2 KVM: s390: optimize float int lock: spin_lock_bh --> spin_lock KVM: s390: use hrtimer for clock wakeup from idle - v2 KVM: s390: Fix memory slot versus run - v3 ...
