linux-next: manual merge of the security tree with the mm tree

From: Stephen Rothwell

Hi all,

Today's linux-next merge of the security tree got a conflict in:

kernel/auditsc.c

between commit:

cd39427be833 ("auditsc: replace memcpy() with strscpy()")

from the mm-nonmm-unstable branch of the mm tree and commits:

37f670aacd48 ("lsm: use lsm_prop in security_current_getsecid")
13d826e564e2 ("audit: change context data from secid to lsm_prop")

from the security tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
