The man page for mmap() and munmap() says that mmap() and munmap()
only works for page-aligned addresses, sizes and offsets.  Arrange
to give these interfaces what they want.
If I read correctly, it talks only offsets to be page aligned.
Yes, it's not really needed, but as we have to adjust the size anyway to
compensate for the reduced file offset, it makes little difference whether
we align the size or not.
