I do not think they are the same.

This patch says: S5P_SLEEP need ARM_CPU_SUSPEND, or can not pass
compiling (S5P_SLEEP need some functions in ARM_CPU_SUSPEND).

Your patch means PLAT_SAMSUNG need ARM_CPU_SUSPEND, but in fact,
PLAT_SAMSUNG may not need ARM_CPU_SUSPEND.

I guess, this error output means S5P_SLEEP and PM need ARM_CPU_SUSPEND
(which has the implementation of 'cpu_resume' and 'cpu_suspend')


Thanks.
