Michel Lespinasse 59d4d125b7 BACKPORT: FROMLIST: mm: implement speculative handling in filemap_fault()
Extend filemap_fault() to handle speculative faults.

In the speculative case, we will only be fishing existing pages out of
the page cache. The logic we use mirrors what is done in the
non-speculative case, assuming that pages are found in the page cache,
are up to date and not already locked, and that readahead is not
necessary at this time. In all other cases, the fault is aborted to be
handled non-speculatively.

Conflicts:
    mm/filemap.c

1. Added back file_ra_state variable used by SPF path.
2. Updated comment for filemap_fault to reflect SPF locking rules.
