Subject: [PATCH 0/2][RFC v6] Ignore bogus sleep time if pm_trace is enabled

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. 

Chen Yu (2):
  timekeeping: Ignore the bogus sleep time if pm_trace is enabled
  PM / sleep: save/restore RTC time after resumed if pm_trace enabled
