    drivers/rtc/rtc-cmos.c: don't disable hpet emulation on suspend
    
    BugLink: http://bugs.launchpad.net/bugs/1178361
    
    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.

Title:
  [Gigabyte GA-MA78GPM-DS2H] ACPI wakeup fails if HPET enabled in BIOS

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  if I type this (as root):
  echo `date '+%s' -d '+ 5 minutes'` > /sys/class/rtc/rtc0/wakealarm

  or:
  rtcwake -d rtc0 -u -m no -t `date '+%s' -d '+ 5 minutes'`

  and then I shutdown the computer, it used to wake up after 5 minutes
  until I upgraded from linux-image-3.8.0-23-generic to a newer package.
  I've always had HPET enabled in BIOS.

  Maybe it's related to this patch found in the changelog
  zdiff /usr/share/doc/linux-image-3.8.0-23-generic/changelog.Debian.gz /usr/share/doc/linux-image-3.8.0-24-generic/changelog.Debian.gz | grep hpet
  >   * drivers/rtc/rtc-cmos.c: don't disable hpet emulation on suspend

  WORKAROUND: If I disable HPET in BIOS, my computer successfully wakes
  up in kernels > 3.8.0-23
