Subject: [PATCH] linux/seqlock.h should #include asm/processor.h for
 cpu_relax()

It uses cpu_relax(), and so needs <asm/processor.h>

Without this patch, I see:

   CC      arch/mn10300/kernel/asm-offsets.s
  In file included from include/linux/time.h:8,
                   from include/linux/timex.h:56,
                   from include/linux/sched.h:57,
                   from arch/mn10300/kernel/asm-offsets.c:7:
  include/linux/seqlock.h: In function 'read_seqbegin':
  include/linux/seqlock.h:91: error: implicit declaration of function 'cpu_relax'

whilst building asb2364_defconfig on MN10300.
