      ACPI / PM: Do not enable GPEs for system wakeup in advance · cb1cb178
      Rafael J. Wysocki authored
      After commit 9630bdd9
      (ACPI: Use GPE reference counting to support shared GPEs) the wakeup
      enable mask bits of GPEs are set as soon as the GPEs are enabled to
      wake up the system.  Unfortunately, this leads to a regression
      reported by Michal Hocko, where a system is woken up from ACPI S5 by
      a device that is not supposed to do that, because the wakeup enable
      mask bit of this device's GPE is always set when
      acpi_enter_sleep_state() calls acpi_hw_enable_all_wakeup_gpes(),
      although it should only be set if the device is supposed to wake up
      the system from the target state.
      
      To work around this issue, rework the ACPI power management code so
      that GPEs are not enabled to wake up the system upfront, but only
      during a system state transition when the target state of the system
      is known.  [Of course, this means that the reference counting of
      "wakeup" GPEs doesn't really make sense and it is sufficient to
      set/unset the wakeup mask bits for them during system sleep
      transitions.  This will allow us to simplify the GPE handling code
      quite a bit, but that change is too intrusive for 2.6.35.]
