[PATCH 0/4] Remove/consolidate calls to find_get_entry

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

As part of the THP work, I audited the callers of find_get_entry() and
found one bug and three opportunities for optimisation.  Patch 2 is the
bugfix as it depends on using the same code as mincore_page().

I don't really like having find_get_swap_page() in mincore.c, but I
can't find anywhere better to put it.

Matthew Wilcox (Oracle) (4):
  mm: Factor find_get_swap_page out of mincore_page
  mm: Use find_get_swap_page in memcontrol
  mm: Optimise madvise WILLNEED
  proc: Optimise smaps for shmem entries
