From: Tom Lendacky <thomas.lendacky@xxxxxxx> commit f10e80a19b07b58fc2adad7945f8313b01503bae upstream. When booting with SME active, EFI tables must be mapped unencrypted since they were built by UEFI in unencrypted memory. Update the list of tables to be checked during early_memremap() processing to account for the EFI TPM tables. This fixes a bug where an EFI TPM log table has been created by UEFI, but it lives in memory that has been marked as usable rather than reserved.
