thanks for this info. I selected a board and compile of linux-next now
fails with:

  LD      .tmp_vmlinux1
arch/arm/mach-exynos/built-in.o: In function `exynos4_pm_resume':
/data/lemmy/linux.trees.git/arch/arm/mach-exynos/pm.c:385: undefined reference to `scu_enable'
make[1]: *** [.tmp_vmlinux1] Error 1

This is because scu_enable() is only available with CONFIG_SMP=y which
is not set for Exynos.
