[PATCHv2 1/2] powerpc/powernv: include asm/smp.h to fix UP build failure

From: Shreyas B. Prabhu
Date: Fri Jun 06 2014 - 06:22:37 EST

Build throws following errors when CONFIG_SMP=n
arch/powerpc/platforms/powernv/setup.c: In function âpnv_kexec_wait_secondaries_downâ:
arch/powerpc/platforms/powernv/setup.c:179:4: error: implicit declaration of function âget_hard_smp_processor_idâ
rc = opal_query_cpu_status(get_hard_smp_processor_id(i),

The usage of get_hard_smp_processor_id() needs the declaration from
<asm/smp.h>. The file setup.c includes <linux/sched.h>, which in-turn
includes <linux/smp.h>. However, <linux/smp.h> includes <asm/smp.h>
only on SMP configs and hence UP builds fail.

Fix this by directly including <asm/smp.h> in setup.c unconditionally.
