ACPI: Handle ACPI0007 Device in acpi_early_set_pdc
After | commit d8191fa4a33fdc817277da4f2b7f771ff605a41c | Author: Alex Chiang <achiang@hp.com> | Date: Mon Feb 22 12:11:39 2010 -0700 | | ACPI: processor: driver doesn't need to evaluate _PDC | | Now that the early _PDC evaluation path knows how to correctly | evaluate _PDC on only physically present processors, there's no | need for the processor driver to evaluate it later when it loads. | | To cover the hotplug case, push _PDC evaluation down into the | hotplug paths. only cpu with Processor Statement get processed with _PDC If bios is using Device object instead of Processor statement. SSDTs for Pstate/Cstate/Tstate can not be loaded dynamically. Need to try to scan ACPI0007 in addition to Processor. That commit is between 2.6.34-rc1 and 2.6.34-rc2, so stable tree for 2.6.34+ need this patch.
