Compiling my exynos-config with linux-next gives me:

  CC      arch/arm/kernel/process.o
In file included from /data/lemmy/linux.trees.git/arch/arm/mach-exynos/include/mach/system.h:16:0,
                 from /data/lemmy/linux.trees.git/arch/arm/kernel/process.c:64:
/data/lemmy/linux.trees.git/arch/arm/plat-samsung/include/plat/system-reset.h:19:2: error: #error Fix me up

I better not ask the question how such an #error statement can come
through to linux-next. But what I can say is that I will not merge
your code until you guys make sure that your upstream platform code has
enough quality so that it at least compiles.

I attach the config I used for my compile-test.
