x86/sev: Use "SEV: " prefix for messages from sev.c (2021-06-23 11:56:18 +0200)
----------------------------------------------------------------
- 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
----------------------------------------------------------------
Brijesh Singh (1):
x86/sev: Add defines for GHCB version 2 MSR protocol requests
Joerg Roedel (7):
x86/sev: Fix error message in runtime #VC handler
x86/insn-eval: Make 0 a valid RIP for insn_get_effective_ip()
x86/insn: Extend error reporting from insn_fetch_from_user[_inatomic]()
x86/sev: Propagate #GP if getting linear instruction address failed
x86/sev: Make sure IRQs are disabled while GHCB is active
x86/sev: Split up runtime #VC handler for correct state tracking
x86/sev: Use "SEV: " prefix for messages from sev.c
