Subject: linux-next: manual merge of the char-misc tree with the block tree

Hi all,

Today's linux-next merge of the char-misc tree got a conflict in
drivers/char/mem.c between commit b4caecd48005 ("fs: introduce
f_op->mmap_capabilities for nommu mmap support") from the block tree
and commit 73f0718e74e2 ("drivers: char: mem: Make /dev/mem an optional
device") from the char-misc tree.

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

Cheers,
