This series contains few clean up, minor bug fixes and
Convert get_user_pages() to pin_user_pages().

I'm compile tested this, but unable to run-time test,
so any testing help is much appriciated.

        Address Dan's review comments to return -ERRNO for partially
        mapped pages and changed the other patches in series accordingly.
        Minor update in change logs.
