Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Radim Krčmář: "PPC: - Fix a bug causing occasional machine check exceptions on POWER8 hosts (introduced in 4.16-rc1) x86: - Fix a guest crashing regression with nested VMX and restricted guest (introduced in 4.16-rc1) - Fix dependency check for pv tlb flush (the wrong dependency that effectively disabled the feature was added in 4.16-rc4, the original feature in 4.16-rc1, so it got decent testing)" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: x86: Fix pv tlb flush dependencies KVM: nVMX: sync vmcs02 segment regs prior to vmx_set_cr0 KVM: PPC: Book3S HV: Fix duplication of host SLB entries
