From 3be5b49e8f1002bc562a2b4670093e4ebf27b4e9 Mon Sep 17 00:00:00 2001 From: Glauber Costa <gcosta@redhat.com> Date: Mon, 3 Mar 2008 14:12:49 -0300 Subject: [PATCH] x86: make stop_this_cpu looks exactly equal in both arches with the hlt_works change, it is possible to have i386 and x86_64 stop_this_cpu() looking exactly the same. They can, after that, be merged.
