Merge branch 'kvm-updates/2.6.28' of git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm
* 'kvm-updates/2.6.28' of git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm: (134 commits) KVM: ia64: Add intel iommu support for guests. KVM: ia64: add directed mmio range support for kvm guests KVM: ia64: Make pmt table be able to hold physical mmio entries. KVM: Move irqchip_in_kernel() from ioapic.h to irq.h KVM: Separate irq ack notification out of arch/x86/kvm/irq.c KVM: Change is_mmio_pfn to kvm_is_mmio_pfn, and make it common for all archs KVM: Move device assignment logic to common code KVM: Device Assignment: Move vtd.c from arch/x86/kvm/ to virt/kvm/ KVM: VMX: enable invlpg exiting if EPT is disabled KVM: x86: Silence various LAPIC-related host kernel messages KVM: Device Assignment: Map mmio pages into VT-d page table KVM: PIC: enhance IPI avoidance KVM: MMU: add "oos_shadow" parameter to disable oos KVM: MMU: speed up mmu_unsync_walk KVM: MMU: out of sync shadow core KVM: MMU: mmu_convert_notrap helper KVM: MMU: awareness of new kvm_mmu_zap_page behaviour KVM: MMU: mmu_parent_walk KVM: x86: trap invlpg KVM: MMU: sync roots on mmu reload ...
