powerpc: Fix SMP build with disabled CPU hotplugging.
Compiling 2.6.33 with SMP enabled and HOTPLUG_CPU disabled gives me the following link errors: LD init/built-in.o LD .tmp_vmlinux1 arch/powerpc/platforms/built-in.o: In function `.smp_xics_setup_cpu': smp.c:(.devinit.text+0x88): undefined reference to `.set_cpu_current_state' smp.c:(.devinit.text+0x94): undefined reference to `.set_default_offline_state' arch/powerpc/platforms/built-in.o: In function `.smp_pSeries_kick_cpu': smp.c:(.devinit.text+0x13c): undefined reference to `.set_preferred_offline_state' smp.c:(.devinit.text+0x148): undefined reference to `.get_cpu_current_state' smp.c:(.devinit.text+0x1a8): undefined reference to `.get_cpu_current_state' make: *** [.tmp_vmlinux1] Error 1 The following change fixes that for me and seems to work as expected.
