2008-02-02ACPI : Update T-state coordination after getting _TSD infoZhao Yakui3-2/+184
Accordint to ACPI spec, the _TSD object provides T-state control cross logical processor dependency information to OSPM. After the _TSD data for all cpus are obtained, OSPM will set up the T-state coordination between CPUs. Of course if the _TSD doesn't exist or _TSD data is incorrect , it is assumed that there is no T-state coordination and T-state is changed independently. Now there is no proper solution to update T-state coordination after one cpu is hotplugged. So this patch won't support hotplugged cpu very well.

2008-02-01ide: move hwif_register() call out of ide_probe_port()Bartlomiej Zolnierkiewicz1-14/+13
* Add BUG_ON(hwif->present) at the start of ide_probe_port(). * Move hwif_register() call (along with setting hwif->present) from ide_probe_port() to ide_device_add_all(). As a result the port will be registered with the device tree _after_: - probing both devices (if both are present) - port reset (if hwif->reset is set) - restoring local IRQs state and re-enabling port IRQ While at it: * Rename hwif_register() to ide_register_port().
