Instead of sorting the memory map and comparing the placement and type of adjacent entries in the EFI memory map, which was implemented to prevent breakage when the pointless and deprecated UEFI property table feature is provided by the firmware, boot with a 1:1 mapping for runtime services in this case, which works around the issue as well. Also, move the code that handles this feature into arch/x86, which is the only architecture which is known to have shipped systems with this feature enabled.
