#     
#     Pull x86 SEV updates from Borislav Petkov:
#     
#      - Differentiate the type of exception the #VC handler raises depending
#        on code executed in the guest and handle the case where failure to
#        get the RIP would result in a #GP, as it should, instead of in a #PF
#     
#      - Disable interrupts while the per-CPU GHCB is held
#     
#      - Split the #VC handler depending on where the #VC exception has
#        happened and therefore provide for precise context tracking like the
#        rest of the exception handlers deal with noinstr regions now
#     
#      - Add defines for the GHCB version 2 protocol so that further shared
#        development with KVM can happen without merge conflicts
#     
#      - The usual small cleanups
#
