SubjectRe: Fix "buggy BIOS check" when CPUs are hot removed
From
Date
This patch too seems malformed. Resending and also find attached.

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.
