[POWERPC] Wrap cpu_die() with CONFIG_HOTPLUG_CPU
Per email discussion, it appears that rtas_stop_self() and pSeries_mach_cpu_die() should not be compiled if CONFIG_HOTPLUG_CPU is not defined. This patch adds #ifdefs around these bits of code. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
