[POWERPC] Use __get_cpu_var in time.c
Use __get_cpu_var(x) instead of per_cpu(x, smp_processor_id()), as it is optimized on ppc64 to access the current cpu's per-cpu offset directly; it's local_paca.offset instead of TOC->paca[local_paca->processor_id].offset. This is the trivial portion, two functions with one use each. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
