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

Hi all,

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

  arch/mips/kernel/syscalls/Makefile

between commit:

  ccb21774863a ("MIPS: UAPI: unexport unistd_nr_{n32,n64,o32}.h")

from Linus' tree and commit:

  865fa29f7dd1 ("arch: syscalls: add missing FORCE and fix 'targets' to make if_changed work")

from the kbuild 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
