Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Paolo Bonzini: "Quite a few fixes for x86: nested virtualization save/restore, AMD nested virtualization and virtual APIC, 32-bit fixes, an important fix to restore operation on older processors, and a bunch of hyper-v bugfixes. Several are marked stable. There are also fixes for GCC warnings and for a GCC/objtool interaction" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: x86: Mark expected switch fall-throughs KVM: x86: fix TRACE_INCLUDE_PATH and remove -I. header search paths KVM: selftests: check returned evmcs version range x86/kvm/hyper-v: nested_enable_evmcs() sets vmcs_version incorrectly KVM: VMX: Move vmx_vcpu_run()'s VM-Enter asm blob to a helper function kvm: selftests: Fix region overlap check in kvm_util kvm: vmx: fix some -Wmissing-prototypes warnings KVM: nSVM: clear events pending from svm_complete_interrupts() when exiting to L1 svm: Fix AVIC incomplete IPI emulation svm: Add warning message for AVIC IPI invalid target KVM: x86: WARN_ONCE if sending a PV IPI returns a fatal error KVM: x86: Fix PV IPIs for 32-bit KVM host x86/kvm/hyper-v: recommend using eVMCS only when it is enabled x86/kvm/hyper-v: don't recommend doing reset via synthetic MSR kvm: x86/vmx: Use kzalloc for cached_vmcs12 KVM: VMX: Use the correct field var when clearing VM_ENTRY_LOAD_IA32_PERF_GLOBAL_CTRL KVM: x86: Fix single-step debugging x86/kvm/hyper-v: don't announce GUEST IDLE MSR support
