From b4d1b825785847cddee6d104113da913f2ca8efb Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 14 Oct 2005 15:26:08 -0700 Subject: [SPARC64]: Fix powering off on SMP. Doing a "SUNW,stop-self" firmware call on the other cpus is not the correct thing to do when dropping into the firmware for a halt, reboot, or power-off. For now, just do nothing to quiet the other cpus, as the system should be quiescent enough. Later we may decide to implement smp_send_stop() like the other SMP platforms do. Based upon a report from Christopher Zimmermann. Signed-off-by: David S.
