However, next time please CC ACPI-related patches to linux-acpi rather than to linux-pm (or you can do both if the patch is PM-related anyway). Thanks!

When MADT is parsed, print CORE_PIC information as below: ACPI: CORE PIC (processor_id[0x00] core_id[0x00] enabled) ACPI: CORE PIC (processor_id[0x01] core_id[0x01] enabled) ... ACPI: CORE PIC (processor_id[0xff] core_id[0xff] enabled) This debug information will be very helpful to bring up early systems to see if processor_id and core_id are matched or not as spec defined.
