linux-next: manual merge of the arm-soc tree with the arm tree

[sfr@canb.auug.org.au (Stephen Rothwell)]

Hi all,

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

  arch/arm/mach-ux500/platsmp.c

between commit:

  6996cbb23721 ("ARM: 8641/1: treewide: Replace uses of virt_to_phys with __pa_symbol")

from the arm tree and commit:

  9e634cae7256 ("ARM: ux500: simplify secondary boot")

from the arm-soc 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.
