ppc64/powerpc: Fix time initialization on SMP systems
This moves smp_space_timers from arch/ppc64/kernel/smp.c to arch/powerpc/kernel/time.c and makes it initialize last_jiffy[] instead of paca[].next_jiffy_update_tb, since last_jiffy[] is now what the time code uses. It also declares smp_space_timers in include/asm-powerpc/time.h and gets rid of an ifdef in div128_by_32. Signed-off-by: Paul Mackerras <paulus@samba.org>
