[0/3] Three memory-failure fixes

Message

I've been looking at the memory-failure code and I believe I have found
three bugs that need fixing -- one going all the way back to 2010!
I'll have more patches later to use folios more extensively but didn't
want these bugfixes to get caught up in that.

Matthew Wilcox (Oracle) (3):
  mm/memory-failure: Pass the folio and the page to collect_procs()
  mm/memory-failure: Check the mapcount of the precise page
  mm/memory-failure: Cast index to loff_t before shifting it
