From 088df4d256227b3d927bb6ed57e66d138da0565c Mon Sep 17 00:00:00 2001 From: Linas Vepstas Date: Thu, 16 Nov 2006 15:41:15 -0600 Subject: [PATCH] [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.
