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
