Merge tag 'kvm-x86-vmx-6.3' of https://github.com/kvm-x86/linux into HEAD
KVM VMX changes for 6.3: - Handle NMI VM-Exits before leaving the noinstr region - A few trivial cleanups in the VM-Enter flows - Stop enabling VMFUNC for L1 purely to document that KVM doesn't support EPTP switching (or any other VM function) for L1 - Fix a crash when using eVMCS's enlighted MSR bitmaps
