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

- 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
