spinlock_up.h: include asm/processor.h in for cpu_relax
Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h and this was a path to including asm/processor.h. We need to include it excplicitly now. Fixes this build error on sparc32 (at least): In file included 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/sparc/kernel/asm-offsets.c:13: include/linux/spinlock.h: In function 'spin_unlock_wait': include/linux/spinlock.h:360: error: implicit declaration of function 'cpu_relax Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
