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:
Merge tag 'kvm-riscv-fixes-6.6-1' of https://github.com/kvm-riscv/linux into HEAD (2023-09-23 05:35:55 -0400)

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.
---------------------------------------------------------------- Peter Gonda (1): KVM: SVM: Update SEV-ES shutdown intercepts with more metadata
Sean Christopherson (2): KVM: x86: Refactor can_emulate_instruction() return to be more expressive KVM: SVM: Treat all "skip" emulation for SEV guests as outright failures
