From 107ce721abddbd876aa6203ac982821e405400e9 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Sat, 16 Apr 2005 15:24:52 -0700 Subject: [PATCH] [PATCH] x86_64: disable interrupts during SMP bogomips checking Port over a i386 kludge from rusty to x86-64 I don't think it is a full solution, but the upcomming smp bootup rewrite will solve it. This fixes BUGs at bootup on bigger x86-64 systems.
