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

Hi all,

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

  init/Kconfig

between commit:

  b688f369ae0d ("compiler_types: Introduce __nonstring_array")

from Linus' tree and commit:

  e7607f7d6d81 ("ARM: 9443/1: Require linker to support KEEP within OVERLAY for DCE")

from the arm 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.
