From ff6e8c0d5e47f0ceeebde86ec2f5919dbd5beb67 Mon Sep 17 00:00:00 2001 From: Zachary Amsden Date: Fri, 6 Jan 2006 00:11:50 -0800 Subject: [PATCH] x86: Cr4 is valid on some 486s So some 486 processors do have CR4 register. Allow them to present it in register dumps by using the old fault technique rather than testing processor family. Thanks to Maciej for noticing this.
