[PATCH] ppc64: Add missing barrier() in kexec code Mikey and I were testing kexec and hit a lockup. It turns out gcc 4.0 optimises the kexec_prepare_cpus loop so we avoid reloading paca.hw_cpu_id. A gcc barrier() fixes the problem. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
