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...

   LD      init/built-in.o

/home/snawrocki/linux/media_tree/arch/arm/mach-s3c24xx/sleep.S:83:
