sh: Fix mmap2 for handling differing PAGE_SIZEs.
mmap2 uses a fixed page shift of 12, regardless of the PAGE_SIZE setting. Fix up the mmap2 code to add some sanity checks on the mapping, and to update pgoff accordingly. Error handling bits based on 4280e312 ("frv: fix mmap2 error handling"). Signed-off-by:Toshinobu Sugioka <sugioka@itonet.co.jp> Signed-off-by:
