Cover letter [PATCH 0/5] mm: Ability to monitor task memory changes (v4)

This is the resend and (while the iron is hot) the request for merge of the implementation of the soft-dirty bit concept that should help to track changes in user memory.

This set differs from what Andrew has sent recently in a single point -- the way pagemap entries' bits are reused (patch #5, and one hunk about Documantation/ file in patch #4). Other places hasn't changed at all.

Thanks,
Pavel
