Subject: linux-next: manual merge of the mailbox tree with the arc-soc tree

Hi all,

Today's linux-next merge of the mailbox tree got conflicts in:

  drivers/mailbox/Kconfig
  drivers/mailbox/Makefile

between commit:

  fe2aa2361ddb ("mailbox: add CIX mailbox driver")

from the arc-soc tree and commit:

  6aecd1f31f8e ("mailbox: Add support for bcm74110")

from the mailbox 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.
