[v3,0/3] xfs: fix maxbytes problems on 32-bit systems

Hi all,

Here's a series of patches to fix some problems related to s_maxbytes
that I found by running fstests in a 32-bit VM.  The first step is to
fix bunmapi during inactivation so that it cleans out /all/ the blocks
of an unlinked file instead of leaking them; and the second is to fix
the s_maxbytes computation to avoid setting a limit larger than what the
pagecache supports.

This has been lightly tested with fstests.  Enjoy!
Comments and questions are, as always, welcome.
