I was trying to understand how it was safe to test PageLocked on a tail
page and started looking at how the pageflag policies were implemented.
I found three actual bugs (patches 5, 7 & 8), improved the documentation
and renamed a pile of things to be more readily explainable.

Matthew Wilcox (8):
  mm: Rename PF argument to modify
  mm: Rename PF_NO_TAIL to PF_TAIL_READ
  mm: Turn PF_POISONED_CHECK into CheckPageInit
  mm: Improve page flag policy documentation
  mm: Fix bug in page flags checking
  mm: Turn page policies into functions
  mm: Always check PagePolicyNoCompound
  mm: Optimise PagePolicyTailRead
