Dan Williams 6e2608dfd9 xfs, dax: introduce xfs_dax_aops 
In preparation for the dax implementation to start associating dax pages
to inodes via page->mapping, we need to provide a 'struct
address_space_operations' instance for dax. Otherwise, direct-I/O
triggers incorrect page cache assumptions and warnings like the
following:

 WARNING: CPU: 27 PID: 1783 at fs/xfs/xfs_aops.c:1468
 xfs_vm_set_page_dirty+0xf3/0x1b0 [xfs]

...where the default set_page_dirty() handler assumes that dirty state
is being tracked in 'struct page' flags.
