[0/3] memmap_init_zone improvements

Message

Three small patches that improve memmap_init_zone() and also fix a small
deferred pages bug.

The improvements include reducing number of ifdefs and making code more
modular.

The bug is the deferred_init_update() should be called after the mirrored
memory skipping is taken into account.

Pavel Tatashin (3):
  mm: make memmap_init a proper function
  mm: calculate deferred pages after skipping mirrored memory
  mm: move mirrored memory specific code outside of memmap_init_zone
