Merge branch 'akpm' (rest of patches from Andrew)

Merge the left-over patches from Andrew Morton.

This merges the remaining two patches from Andrew's pile of "little bit
more MM".  I mulled it over, and we emailed back and forth with Josef,
and he pointed out where I was wrong.

Rule #51 of kernel maintenance: when somebody makes it clear that they
know the code better than you did, stop arguing and just apply the damn
patch.

Add a third patch by me to add a comment for the case that I had thought
was buggy and Josef corrected me on.

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  filemap: add a comment about FAULT_FLAG_RETRY_NOWAIT behavior
  filemap: drop the mmap_sem for all blocking operations
  filemap: kill page_cache_read usage in filemap_fault
