Tom Lendacky 39336f4ffb x86/efi: Add GHCB mappings when SEV-ES is active ... Calling down to EFI runtime services can result in the firmware performing VMGEXIT calls. The firmware is likely to use the GHCB of the OS (e.g., for setting EFI variables), so each GHCB in the system needs to be identity-mapped in the EFI page tables, as unencrypted, to avoid page faults.
