Subject: linux-next: manual merge of the block tree with the l2-mtd tree

Hi Jens,

Today's linux-next merge of the block tree got a conflict in
drivers/mtd/mtdcore.c between commit 3efe41be224c ("mtd: implement
common reboot notifier boilerplate") from the  tree and commit
b4caecd48005 ("fs: introduce f_op->mmap_capabilities for nommu mmap
support") from the block tree.

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