tile: cleanup the comment in init_pgprot
In tile vmlinux, the rodata area start after the _sdata. The rodata area is included between [_sdata, __end_rodata), and is handled at an earlier point. The page walk starts at __end_rodata, not _sdata. Signed-off-by: Wang Sheng-Hui <shhuiw@gmail.com> Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
