The following error was observed with SMP=n in v4.0-rc1:

arch/arm/mach-exynos/pm.c: In function 'exynos_cpu0_enter_aftr':
arch/arm/mach-exynos/pm.c:246:4: error: implicit declaration of function 'arch_send_wakeup_ipi_mask' [-Werror=implicit-function-declaration]

As the code unconditionally calls a function only available with SMP=y,
make the Exynos PM support depend on SMP.

Hi,

Thanks for the patch but this already waits for Kukjin top be picked
up. The first patch was similar to yours (adds dependency on SMP),
sent on 4th of February:
https://patchwork.ozlabs.org/patch/436231/

But later Bartlomiej fixed this in other way (allowing to use cpuidle
on non-SMP):
https://patchwork.ozlabs.org/patch/436445/

Unfortunately none of them were picked up.

Best regards,
Krzysztof
