PARTITION_SUPPORT needs to be set before doing the compare on version number so the bit width test does not get invalid data.

drivers/rtc/rtc-cmos.c: don't disable hpet emulation on suspend 2013-05-08T02:57:26+00:00 Derek Basehore dbasehore@chromium.org 2013-04-29T23:20:23+00:00 10eb78f693be5d924d8ae19264efc8da2d6cb8a3 commit e005715efaf674660ae59af83b13822567e3a758 upstream. There's a bug where rtc alarms are ignored after the rtc cmos suspends but before the system finishes suspend. Since hpet emulation is disabled and it still handles the interrupts, a wake event is never registered which is done from the rtc layer. This patch reverts commit d1b2efa83fbf ("rtc: disable hpet emulation on suspend") which disabled hpet emulation. To fix the problem mentioned in that commit, hpet_rtc_timer_init() is called directly on resume.
