- Limit grub_malloc() on x86_64 to < 31bit addresses, as some devices seem to have a colossally broken storage controller (or UEFI driver) that can't do DMA to higher memory addresses, but fails silently. Resolves: rhbz#1626844 (possibly really resolving it this time.) - Also integrate Hans's attempt to fix the related error from -54, but do it the other way around: try the low addresses first and *then* the high one if the allocation fails. This way we'll get low regions by default, and if kernel/initramfs don't fit anywhere, it'll try the higher addresses. Related: rhbz#1624532 - Coalesce all the intermediate debugging junk from -54/-55/-56. Signed-off-by: Peter Jones <pjones@redhat.com>
