mm now supports invalidatepage_range address space operation which is
useful to allow truncating page range which is not aligned to the end of
the page. This will help in punch hole implementation once
truncate_inode_pages_range() is modify to allow this as well.
With this commit ocfs2 now register only invalidatepage_range.
