xfs: consolidate the various page fault handlers Add a new __xfs_filemap_fault helper that implements all four page fault callouts, and make these methods themselves small stubs that set the correct write_fault flag, and exit early for the non-DAX case for the hugepage related ones. Also remove the extra size checking in the pfn_fault path, which is now handled in the core DAX code. Life would be so much simpler if we only had one method for all this.
