linux-next: manual merge of the block tree with Linus' tree

[Stephen Rothwell]

Hi Jens,

Today's linux-next merge of the block tree got a conflict in
drivers/md/dm.c between commits 3a1407559a59 ("dm: fix NULL pointer
when clone_and_map_rq returns !DM_MAPIO_REMAPPED") and e5d8de32cc02
("dm: fix false warning in free_rq_clone() for unmapped requests") from
Linus' tree and commit 5f1b670d0bef ("block, dm: don't copy bios for
request clones") from the block tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
