Toshi Kani dbe6ec8156 ext2/4, xfs: call thp_get_unmapped_area() for pmd mappings ...

To support DAX pmd mappings with unmodified applications, filesystems
need to align an mmap address by the pmd size.

Call thp_get_unmapped_area() from f_op->get_unmapped_area.

Note, there is no change in behavior for a non-DAX file.
