Subject: linux-next: manual merge of the apparmor tree with Linus' tree

Hi all,

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

  security/apparmor/include/policy.h

between commit:

  23375b13f98c ("apparmor: fix PROFILE_MEDIATES for untrusted input")

from Linus' tree and commit:

  06c13f554a71 ("apparmor: re-introduce a variant of PROFILE_MEDIATES_SAFE")

from the apparmor 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.

Cheers,
Stephen Rothwell
