2008-07-30ide/powermac: Fix use of uninitialized pointer on media-bayBenjamin Herrenschmidt
The current ide-pmac calls media_bay_set_ide_infos() with an uninitialized "hwif" argument. The proper fix is to split the allocation of the hwif from its registration in order to properly setup the mediabay informations before registration.

2008-02-23PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki
During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.
