The patch titled acpi: fix "buggy BIOS check" when CPUs are hot removed has been removed from the -mm tree. Its filename was acpi-fix-buggy-bios-check-when-cpus-are-hot-removed.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: acpi: fix "buggy BIOS check" when CPUs are hot removed From: Alok Kataria <akataria@xxxxxxxxxx> 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.
