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

Hi all,

Today's linux-next merge of the arm-soc tree got a conflict in
arch/arm/mach-ux500/timer.c between commit 8eed6eac103b ("ARM: ux500:
convert to twd_local_timer_register() interface") from the arm tree and
commit b9576623c421 ("ARM: plat-nomadik: get rid of global mtu base
pointer") from the arm-soc tree.

I fixed it up (I think - see below) and can carry the fix as necessary.

Cheers,
