[GIT PULL] KVM: x86: SVM changes for 6.7

[Sean Christopherson]

An enhancement to help userspace deal with SEV-ES guest crashes, and cleanups
related to not being able to do "skip" emulation for SEV guests.

The following changes since commit 5804c19b80bf625c6a9925317f845e497434d6d3:

  KVM: SVM: Treat all "skip" emulation for SEV guests as outright failures (2023-10-04 15:08:53 -0700)

----------------------------------------------------------------
KVM SVM changes for 6.7:

 - Report KVM_EXIT_SHUTDOWN instead of EINVAL if KVM intercepts SHUTDOWN while
   running an SEV-ES guest.

 - Clean up handling "failures" when KVM detects it can't emulate the "skip"
   action for an instruction that has already been partially emulated.  Drop a
   hack in the SVM code that was fudging around the emulator code not giving
   SVM enough information to do the right thing.
