Subject: [PATCH] mm: vmscan: remove shrink_control arg from
 do_try_to_free_pages()

There is no need passing on a shrink_control struct from
try_to_free_pages() and friends to do_try_to_free_pages() and then to
shrink_zones(), because it is only used in shrink_zones() and the only
field initialized on the top level is gfp_mask, which is always equal to
scan_control.gfp_mask.  So let's move shrink_control initialization to
shrink_zones().
