nommu: fix two build breakages

My 58fa879e1e640a1856f736b418984ebeccee1c95 "mm: FOLL flags for GUP flags"
broke CONFIG_NOMMU build by forgetting to update nommu.c foll_flags type:

  mm/nommu.c:171: error: conflicting types for `__get_user_pages'
  mm/internal.h:254: error: previous declaration of `__get_user_pages' was here
  make[1]: *** [mm/nommu.o] Error 1

My 03f6462a3ae78f36eb1f0ee8b4d5ae2f7859c1d5 "mm: move highest_memmap_pfn"
broke CONFIG_NOMMU build by forgetting to add a nommu.c highest_memmap_pfn:

  mm/built-in.o: In function `memmap_init_zone':
  (.meminit.text+0x326): undefined reference to `highest_memmap_pfn'
  mm/built-in.o: In function `memmap_init_zone':
  (.meminit.text+0x32d): undefined reference to `highest_memmap_pfn'

Fix both breakages, and give myself 30 lashes (ouch!)
