Merge branch 'kvm-updates/2.6.29' of git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm
* 'kvm-updates/2.6.29' of git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm: (140 commits) KVM: MMU: handle large host sptes on invlpg/resync KVM: Add locking to virtual i8259 interrupt controller KVM: MMU: Don't treat a global pte as such if cr4.pge is cleared MAINTAINERS: Maintainership changes for kvm/ia64 KVM: ia64: Fix kvm_arch_vcpu_ioctl_[gs]et_regs() KVM: x86: Rework user space NMI injection as KVM_CAP_USER_NMI KVM: VMX: Fix pending NMI-vs.-IRQ race for user space irqchip KVM: fix handling of ACK from shared guest IRQ KVM: MMU: check for present pdptr shadow page in walk_shadow KVM: Consolidate userspace memory capability reporting into common code KVM: Advertise the bug in memory region destruction as fixed KVM: use cpumask_var_t for cpus_hardware_enabled KVM: use modern cpumask primitives, no cpumask_t on stack KVM: Extract core of kvm_flush_remote_tlbs/kvm_reload_remote_mmus KVM: set owner of cpu and vm file operations anon_inodes: use fops->owner for module refcount x86: KVM guest: kvm_get_tsc_khz: return khz, not lpj KVM: MMU: prepopulate the shadow on invlpg KVM: MMU: skip global pgtables on sync due to cr3 switch KVM: MMU: collapse remote TLB flushes on root sync ...
