I've now queued the first three patches in this series for the next
merge window, which is basically the preparation for moving to LMB.
Essentially, that's:

- removing useless includes of linux/bootmem.h
- sorting the meminfo array prior to sanity_check_meminfo()
- moving the mapping of lowmem into mmu.c and making create_mapping()
  static

None of these changes should affect any currently merged platforms, and
wouldn't be affected by Ben's LMB updates either.
