Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM updates from Paolo Bonzini: "Small release, the most interesting stuff is x86 nested virt improvements. x86: - userspace can now hide nested VMX features from guests - nested VMX can now run Hyper-V in a guest - support for AVX512_4VNNIW and AVX512_FMAPS in KVM - infrastructure support for virtual Intel GPUs. PPC: - support for KVM guests on POWER9 - improved support for interrupt polling - optimizations and cleanups. s390: - two small optimizations, more stuff is in flight and will be in 4.11. ARM: - support for the GICv3 ITS on 32bit platforms" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (94 commits) arm64: KVM: pmu: Reset PMSELR_EL0.SEL to a sane value before entering the guest KVM: arm/arm64: timer: Check for properly initialized timer on init KVM: arm/arm64: vgic-v2: Limit ITARGETSR bits to number of VCPUs KVM: x86: Handle the kthread worker using the new API KVM: nVMX: invvpid handling improvements KVM: nVMX: check host CR3 on vmentry and vmexit KVM: nVMX: introduce nested_vmx_load_cr3 and call it on vmentry KVM: nVMX: propagate errors from prepare_vmcs02 KVM: nVMX: fix CR3 load if L2 uses PAE paging and EPT KVM: nVMX: load GUEST_EFER after GUEST_CR0 during emulated VM-entry KVM: nVMX: generate MSR_IA32_CR{0,4}_FIXED1 from guest CPUID KVM: nVMX: fix checks on CR{0,4} during virtual VMX operation KVM: nVMX: support restore of VMX capability MSRs KVM: nVMX: generate non-true VMX MSRs based on true versions KVM: x86: Do not clear RFLAGS.TF when a singlestep trap occurs.
