Given the precedent of memblock_mark_nomap(), as long as the reusable reserved-memory regions also get split into distinct memblocks, then it seems like in principle we ought to be able to give them a new MEMBLOCK_PTEMAP (or whatever) flag which could then be picked up in map_mem() without needing to override force_pte_mapping() globally?
Please don't. _nomap() caused enough pain.
Cheers, Robin.
