linux-next: manual merge of the akpm-current tree with the block tree

[Stephen Rothwell]

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in:

  block/blk-mq.c

between commit:

  3ef28e83ab15 ("block: generic request_queue reference counting")

from the block tree and commit:

  7cc8e61bde7a ("mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd")
  415a13cc1c3c ("mm, page_alloc: rename __GFP_WAIT to __GFP_RECLAIM")

from the akpm-current tree.

I fixed it up (the code updated in the latter was moved by the former,
so I applied the following merge fix patch) and can carry the fix as
necessary (no action is required).
