linux-next: manual merge of the akpm-current tree with the v4l-dvb tree

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in
include/linux/kconfig.h between commit 9b174527e7b7 ("[media] Add and
use IS_REACHABLE macro") from the v4l-dvb tree and commit 85ca6a006505
("kconfig-use-macros-which-are-already-defined-fix") from the
akpm-current tree.

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