The patch below will fix it. Cc'ed linux-arch just in case other architectures are affected as well. Subject: [PATCH] smp: add missing init.h include From: Heiko Carstens <heiko.carstens@xxxxxxxxxx> 34db18a05 "smp: move smp setup functions to kernel/smp.c" causes this build error on s390 because of a missing init.h include: CC arch/s390/kernel/asm-offsets.s In file included from /home2/heicarst/linux-2.6/arch/s390/include/asm/spinlock.h:14:0, from include/linux/spinlock.h:87, from include/linux/seqlock.h:29, from include/linux/time.h:8, from include/linux/timex.h:56, from include/linux/sched.h:57, from arch/s390/kernel/asm-offsets.c:10: include/linux/smp.h:117:20: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'setup_nr_cpu_ids' include/linux/smp.h:118:20: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'smp_init' Fix it by adding the include statement.
