// I would expect PhysicalStart and PhysicalEnd to always match here, but
// the region can be merged with a nearby one, thus we check for overlap
// rather than full match. "Desc contains RtReloc" should also do.
// FIXME: Check with Sniki why fuzzy match fails for him and whether
// it is needed at all.
// PhysicalStart match is enough, but just in case.
// Select firmwares, like Lenovo ThinkPad X240, have insane reserved areas.
// For example 0000000000000000-FFFFFFFFFFFFFFFF 0000000000000000 0000000000000000.
// Any fuzzy matching is prone to errors, so just do exact comparison.
