Merge branch 'kvm-updates/3.4' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm updates from Avi Kivity: "Changes include timekeeping improvements, support for assigning host PCI devices that share interrupt lines, s390 user-controlled guests, a large ppc update, and random fixes." This is with the sign-off's fixed, hopefully next merge window we won't have rebased commits. * 'kvm-updates/3.4' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (130 commits) KVM: Convert intx_mask_lock to spin lock KVM: x86: fix kvm_write_tsc() TSC matching thinko x86: kvmclock: abstract save/restore sched_clock_state KVM: nVMX: Fix erroneous exception bitmap check KVM: Ignore the writes to MSR_K7_HWCR(3) KVM: MMU: make use of ->root_level in reset_rsvds_bits_mask KVM: PMU: add proper support for fixed counter 2 KVM: PMU: Fix raw event check KVM: PMU: warn when pin control is set in eventsel msr KVM: VMX: Fix delayed load of shared MSRs KVM: use correct tlbs dirty type in cmpxchg KVM: Allow host IRQ sharing for assigned PCI 2.3 devices KVM: Ensure all vcpus are consistent with in-kernel irqchip settings KVM: x86 emulator: Allow PM/VM86 switch during task switch KVM: SVM: Fix CPL updates KVM: x86 emulator: VM86 segments must have DPL 3 KVM: x86 emulator: Fix task switch privilege checks arch/powerpc/kvm/book3s_hv.c: included linux/sched.h twice KVM: x86 emulator: correctly mask pmc index bits in RDPMC instruction emulation KVM: mmu_notifier: Flush TLBs before releasing mmu_lock ...
