Commit 9630bdd (ACPI: Use GPE reference counting to support shared GPEs) introduced a suspend regression where boxes resume immediately after being suspended due to the lid or sleep button wakeup status not being cleared properly. This happens if the GPEs corresponding to those devices are not enabled all the time, which apparently is expected by some BIOSes. To fix this problem, enable button and lid GPEs unconditionally during initialization and keep them enabled all the time, regardless of whether or not the ACPI button driver is used.
