This patch set is based on Thomas's previous solution, to bypass the bogus CMOS-RTC sleep time after resumed, thus to avoid damage to timekeeping system. The bogus sleep time comes from pm_trace, which might use CMOS-RTC for debugging purpose.
Meanwhile, a solution to save/restore of CMOS-RTC is also proposed to give better user experience.
