Matthew Wilcox f7ca90b160 dax,ext2: replace the XIP page fault handler with the DAX page fault handler ...

Instead of calling aops->get_xip_mem from the fault handler, the
filesystem passes a get_block_t that is used to find the appropriate
blocks.

This requires that all architectures implement copy_user_page().  At the
time of writing, mips and arm do not.  Patches exist and are in progress.
