Brijesh Singh 9b788f32be x86/efi: Access EFI MMIO data as unencrypted when SEV is active ... SEV guest fails to update the UEFI runtime variables stored in the flash. The following commit: 1379edd596 ("x86/efi: Access EFI data as encrypted when SEV is active") unconditionally maps all the UEFI runtime data as 'encrypted' (C=1). When SEV is active the UEFI runtime data marked as EFI_MEMORY_MAPPED_IO should be mapped as 'unencrypted' so that both guest and hypervisor can access the data.
