Subject: [PATCH 4/7] Replace page_referenced() with wipe_page_reference()
page_referenced() imply "test the page was referenced or not", but
shrink_active_list() use it for drop pte young bit. then, it should be
renamed.
Plus, vm_flags argument is really ugly. instead, introduce new
struct page_reference_context, it's for collect some statistics.
This patch doesn't have any behavior change.
