Subject: [PATCH] sched: remove SD_PREFER_LOCAL in tile arch
commit (sched: recover SD_WAKE_AFFINE in select_task_rq_fair and code
clean up) remove SD_PREFER_LOCAL definition, but left a SD_PREFER_LOCAL
usage in tile arch code. That cause tile arch out of work.
This patch removes the died code from tile arch.
