Subject: [PATCH] powerpc/powernv: Include asm/smp.h to fix UP build failure
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Build throws following errors when CONFIG_SMP=n
arch/powerpc/platforms/powernv/setup.c: In function ‘pnv_kexec_wait_secondaries_down’:
arch/powerpc/platforms/powernv/setup.c:179:4: error: implicit declaration of function ‘get_hard_smp_processor_id’
    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.
