2008-10-10ide: make drive->id an union (take 2)Bartlomiej Zolnierkiewicz
Make drive->id an unnamed union so id can be accessed either by using 'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing drive->id users accordingly (using 'u16 *id' when possible). This is an intermediate step to make ide 'struct hd_driveid'-free. While at it: - Add missing KERN_CONTs in it821x.c. - Use ATA_ID_WORDS and ATA_ID_*_LEN defines. - Remove unnecessary checks for drive->id. - s/drive_table/table/ in ide_in_drive_list(). - Cleanup ide_config_drive_speed() a bit. - s/drive1/dev1/ & s/drive0/dev0/ in ide_undecoded_slave(). v2: Fix typo in drivers/ide/ppc/pmac.c.

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.
