From 6a3ef369100160520f45911fc8c16badcd6a03f3 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Thu, 2 Feb 2023 18:30:06 +0100 Subject: [PATCH] efi: Accept version 2 of memory attributes table commit 636ab417a7aec4ee993916e688eb5c5977570836 upstream. UEFI v2.10 introduces version 2 of the memory attributes table, which turns the reserved field into a flags field, but is compatible with version 1 in all other respects. So let's not complain about version 2 if we encounter it.
