These three patches add three helpers and convert the appropriate
places to use them.

v2:
 - Add page_shift() and compound_nr()
 - Remove unsigned long cast from PAGE_SIZE as it is already unsigned long
 - Update to current Linus tree

Matthew Wilcox (Oracle) (3):
  mm: Introduce page_size()
  mm: Introduce page_shift()
  mm: Introduce compound_nr()
