Subject: start removing writepage instances v2

Hi all,

The VM doesn't need or want ->writepage for writeback and is fine with
just having ->writepages as long as ->migrate_folio is implemented.

This series removes all ->writepage instances that use
block_write_full_page directly and also have a plain mpage_writepages
based ->writepages.

Andrew, can you pick this up through the -mm tree?

Changes since v1:
 - dropped the ext2 and udf patches that Jan merged through
   his tree
 - collected a bunch of ACKs
