From e8c534ec068af1a0845aceda373a9bfd2de62030 Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Tue, 27 Jul 2010 18:53:35 +0200 Subject: x86: Fix keeping track of AMD C1E Accomodate the original C1E-aware idle routine to the different times during boot when the BIOS enables C1E. While at it, remove the synthetic CPUID flag in favor of a single global setting which denotes C1E status on the system.
