Merge branch 'kvm-updates/2.6.30' of git://git.kernel.org/pub/scm/virt/kvm/kvm
* 'kvm-updates/2.6.30' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (113 commits) KVM: VMX: Don't allow uninhibited access to EFER on i386 KVM: Correct deassign device ioctl to IOW KVM: ppc: e500: Fix the bug that KVM is unstable in SMP KVM: ppc: e500: Fix the bug that mas0 update to wrong value when read TLB entry KVM: Fix missing smp tlb flush in invlpg KVM: Get support IRQ routing entry counts KVM: fix sparse warnings: Should it be static? KVM: fix sparse warnings: context imbalance KVM: is_long_mode() should check for EFER.LMA KVM: VMX: Update necessary state when guest enters long mode KVM: ia64: Fix the build errors due to lack of macros related to MSI. ia64: Move the macro definitions related to MSI to one header file. KVM: fix kvm_vm_ioctl_deassign_device KVM: define KVM_CAP_DEVICE_DEASSIGNMENT KVM: ppc: Add emulation of E500 register mmucsr0 KVM: Report IRQ injection status for MSI delivered interrupts KVM: MMU: Fix another largepage memory leak KVM: SVM: set accessed bit for VMCB segment selectors KVM: Report IRQ injection status to userspace. KVM: MMU: remove assertion in kvm_mmu_alloc_page ...
