linux-next: manual merge of the nommu tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi David,

Today's linux-next merge of the nommu tree got a conflict in
kernel/fork.c between commit e6df1035b1b488cafde1e69f1a25f2706c3ac1f7
("kmemcheck: add mm functions") from the kmemcheck tree and commit
f65466230e8afd45f716e5b836711ce270f45105 ("NOMMU: Make VMAs per MM as for
MMU-mode linux") from the nommu tree.

I fixed it up as best I can (see below) and can carry the fix as
necessary (though it would be good if you guys could figure out a better
solution).
