Merge tag 'x86_sev_for_v6.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 SEV updates from Borislav Petkov:
- Map the SNP calling area pages too so that OVMF EFI fw can issue SVSM
calls properly with the goal of implementing EFI variable store in
the SVSM - a component which is trusted by the guest, vs in the
firmware, which is not
- Allow the kernel to handle #VC exceptions from EFI runtime services
properly when running as a SNP guest
- Rework and cleanup the SNP guest request issue glue code a bit
