  x86/sev: Let sev_es_efi_map_ghcbs() map the CA pages too (2025-06-27 14:07:10 +0200)

----------------------------------------------------------------
- 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

----------------------------------------------------------------
Alexey Kardashevskiy (4):
      virt: sev-guest: Contain snp_guest_request_ioctl in sev-guest
      x86/sev: Allocate request in TSC_INFO_REQ on stack
      x86/sev: Document requirement for linear mapping of guest request buffers
      x86/sev: Drop unnecessary parameter in snp_issue_guest_request()

Gerd Hoffmann (2):
      x86/sev/vc: Fix EFI runtime instruction emulation
      x86/sev: Let sev_es_efi_map_ghcbs() map the CA pages too
