NAK. Instead this should never call cleanup_before_linux() and we declare ourselves incompatible to old grub versions. That way we don't lure others into believing you could boot with caches disabled in a UEFI world.
Agreed.
This is my fault by the way, for merging a loader in GRUB that was designed to be used without the linux EFI stub (way, waaaay back). Feel free to shout.
As of GRUB 2.04 release (and cherry-picked into debian Buster before that), the 32-bit and 64-bit UEFI ports use the same loader.
Do you have a reference to this patch set handy?
