When randconfig with MMU for arm s5pv210 (and select all cpu type),

Internal config node to apply common S5P sleep management code.
Can be selected by S5P and newer SoCs with similar sleep procedure.
We have discussed this about two months ago [1] and the conclusion was
to also
remove "select ARM_CPU_SUSPEND if PM" line from
arch/arm/mach-exynos/Kconfig.
It is still unresolved then, I'm getting similar linker errors with
s3c2410_defconfig...
