Merge tag 'kvm-x86-svm-6.8' of https://github.com/kvm-x86/linux into HEAD

KVM SVM changes for 6.8:

 - Revert a bogus, made-up nested SVM consistency check for TLB_CONTROL.

 - Advertise flush-by-ASID support for nSVM unconditionally, as KVM always
   flushes on nested transitions, i.e. always satisfies flush requests.  This
   allows running bleeding edge versions of VMware Workstation on top of KVM.

 - Sanity check that the CPU supports flush-by-ASID when enabling SEV support.

 - Fix a benign NMI virtualization bug where KVM would unnecessarily intercept
   IRET when manually injecting an NMI, e.g. when KVM pends an NMI and injects
   a second, "simultaneous" NMI.
