This patch too seems malformed. Resending and also find attached.
Thanks, Alok
-- Fix "buggy BIOS check" when CPUs are hot added and removed
processor_device_array[pr->id] needs to be set to NULL when removing a CPU. Else the "buggy BIOS check" in acpi_processor_start mistakenly fires when a CPU is removed from the system and then later re-added.
