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

Hi Kukjin,

Today's linux-next merge of the samsung tree got a conflict in
arch/arm/mach-exynos/platsmp.c between commit b1cffebf1029 ("ARM: GIC:
remove direct use of gic_raise_softirq") from the arm-soc tree and commit
3c49d3583839 ("ARM: EXYNOS: Add secure firmware support to secondary CPU
bring-up") from the samsung tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
