Merge tag 'x86_sev_for_v5.14_rc1' of git://git./linux/kernel/git/tip/tip

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
