Revision db677ffa5f5a4f15b9dad4d132b3477b80766d82 authored by Rusty Russell on 05 January 2010, 02:18:49 UTC, committed by Linus Torvalds on 06 January 2010, 00:01:35 UTC
This reverts commit ae1b22f6e46c03cede7cea234d0bf2253b4261cf.

As Linus said in 982d007a6ee: "There was something really messy about
cmpxchg8b and clone CPU's, so if you enable it on other CPUs later, do it
carefully."

This breaks lguest for those configs, but we can fix that by emulating
if we have to.
