[GIT PULL] aio changes for 3.12

[Benjamin LaHaise <bcrl@kvack.org>]

Hell Linus, Al and everyone,

First off, sorry for this pull request being late in the merge window.  Al 
had raised a couple of concerns about 2 items in the series below.  I 
addressed the first issue (the race introduced by Gu's use of mm_populate()),
but he has not provided any further details on how he wants to rework the 
anon_inode.c changes (which were sent out months ago but have yet to be 
commented on).  The bulk of the changes have been sitting in the -next tree 
for a few months, with all the issues raised being addressed.  Please 
consider this pull.  Thanks,

		-ben
