From e295a5ce4b7bb2b8f774fbc576bab45ab6663bc9 Mon Sep 17 00:00:00 2001 From: Keir Fraser Date: Thu, 2 Apr 2009 13:02:13 +0100 Subject: [PATCH] x86: imply 'noapic' from 'nolapic' While in the comments to an earlier submitted (and already applied) patch I claimed to have fixed the need to specify both "nolapic" and "noapic" when "nolapic" alone should already have the intended effect, this doesn't appear to be the case. Here are the missing bits.
