Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull second batch of KVM updates from Radim Krčmář: "General: - move kvm_stat tool from QEMU repo into tools/kvm/kvm_stat (kvm_stat had nothing to do with QEMU in the first place -- the tool only interprets debugfs) - expose per-vm statistics in debugfs and support them in kvm_stat (KVM always collected per-vm statistics, but they were summarised into global statistics) x86: - fix dynamic APICv (VMX was improperly configured and a guest could access host's APIC MSRs, CVE-2016-4440) - minor fixes ARM changes from Christoffer Dall: - new vgic reimplementation of our horribly broken legacy vgic implementation. The two implementations will live side-by-side (with the new being the configured default) for one kernel release and then we'll remove the legacy one. - fix for a non-critical issue with virtual abort injection to guests" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (70 commits) tools: kvm_stat: Add comments tools: kvm_stat: Introduce pid monitoring KVM: Create debugfs dir and stat files for each VM MAINTAINERS: Add kvm tools tools: kvm_stat: Powerpc related fixes tools: Add kvm_stat man page tools: Add kvm_stat vm monitor script kvm:vmx: more complete state update on APICv on/off KVM: SVM: Add more SVM_EXIT_REASONS KVM: Unify traced vector format svm: bitwise vs logical op typo KVM: arm/arm64: vgic-new: Synchronize changes to active state KVM: arm/arm64: vgic-new: enable build KVM: arm/arm64: vgic-new: implement mapped IRQ handling KVM: arm/arm64: vgic-new: Wire up irqfd injection KVM: arm/arm64: vgic-new: Add vgic_v2/v3_enable KVM: arm/arm64: vgic-new: vgic_init: implement map_resources KVM: arm/arm64: vgic-new: vgic_init: implement vgic_init KVM: arm/arm64: vgic-new: vgic_init: implement vgic_create KVM: arm/arm64: vgic-new: vgic_init: implement kvm_vgic_hyp_init ...
