From 04da6af960194ecdee4c29cd3f86e766903418ca Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 5 Dec 2006 17:52:37 +1100 Subject: [PATCH] [POWERPC] Move pSeries_mach_cpu_die() into platforms/pseries/hotplug-cpu.c Move pSeries_mach_cpu_die() into platforms/pseries/hotplug-cpu.c, this allows rtas_stop_self() to be static so remove the prototype. Wire up pSeries_mach_cpu_die() in the initcall, rather than statically in setup.c, the initcall will still run prior to the cpu hotplug code being callable, so there should be no change in behaviour.
