Previously we read sit entries page one by one, this method lost the chance of
reading contiguous page together.
So we read pages as contiguous as possible for better mount performance.

For better read performance, we add a new function to support for merging
contiguous read as the one for write.

I just want the various arch implementations to match
the docs. I know that's stupid.
Maybe if you really don't want to discuss things, you
should fix the documentation.
