parentsh: uncached mapping helpers. (diff)
sh: Build PMB entry links for existing contiguous multi-page mappings.
This plugs in entry sizing support for existing mappings and then builds on top of that for linking together entries that are mapping contiguous areas. This will ultimately permit us to coalesce mappings and promote head pages while reclaiming PMB slots for dynamic remapping. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
