From ba62b077871a5255e271f4fdae57167651839277 Mon Sep 17 00:00:00 2001 From: Alok Kataria Date: Tue, 8 Apr 2008 17:41:56 -0700 Subject: [PATCH] acpi: fix "buggy BIOS check" when CPUs are hot removed Fixes a BUG in ACPI hotplugging. 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.
