sparc32: fix build, fix missing cpu_relax declaration
Fix following sparc (32 bit) build error: CC arch/sparc/kernel/asm-offsets.s In file included from include/linux/seqlock.h:29:0, from include/linux/time.h:8, from include/linux/timex.h:56, from include/linux/sched.h:57, from arch/sparc/kernel/asm-offsets.c:13: include/linux/spinlock.h: In function 'spin_unlock_wait': include/linux/spinlock.h:360:2: error: implicit declaration of function 'cpu_relax' Most likely caused by commit e66eed651fd1 ("list: remove prefetching from regular list iterators") due to include changes.
