[patch 069/198] x86_64: disable interrupts during SMP bogomips checking
From: akpm
Date: Tue Apr 12 2005 - 21:15:56 EST
From: Andi Kleen <ak@xxxxxxx>
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.
