powerpc/powernv: Include asm/smp.h to fix UP build failure
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. Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Reviewed-by: Srivatsa S.
