Werner Zeh 686018988c drivers/pc80/mc146818rtc: Check date and time for sanity ... There are cases where the RTC_VRT bit in register D stays set after a power failure while the real date and time registers can contain rubbish values (can happen when RTC is not buffered). If we do not detect this invalid date and/or time here and keep it, Linux will use these bad values for the initial timekeeper init. This in turn can lead to dates before 1970 in user land which can break a lot assumptions. To fix this, check date and time sanity when the RTC is initialized and reset the values if needed.
