From a0abd520fd69295f4a3735e29a9448a32e101d47 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 16 Feb 2009 17:31:58 -0600 Subject: [PATCH] cpumask: fix powernow-k8: partial revert of 2fdf66b491ac706657946442789ec644cc317e1a Impact: fix powernow-k8 when acpi=off (or other error). There was a spurious change introduced into powernow-k8 in this patch: so that we try to "restore" the cpus_allowed we never saved. We revert that file. See lkml "[PATCH] x86/powernow: fix cpus_allowed brokage when acpi=off" from Yinghai for the bug report.
