mm/rmap: make rmap_walk to get the rmap_walk_control argument
In each rmap traverse case, there is some difference so that we need function pointers and arguments to them in order to handle these For this purpose, struct rmap_walk_control is introduced in this patch, and will be extended in following patch. Introducing and extending are separate, because it clarify changes.
