m32r: Use generic PREEMPT config
Use the generic preempt config definition in m32r instead of using a custom one. This also makes it handle the new CONFIG_PREEMPT_COUNT that need to be selected by CONFIG_PREEMPT. Without that it breaks kernel/sched.c: In function 'preempt_schedule': kernel/sched.c:4364: error: implicit declaration of function 'add_preempt_count_notrace' kernel/sched.c:4366: error: implicit declaration of function 'sub_preempt_count_notrace' Reported-by: NIngo Molnar <mingo@elte.hu> Signed-off-by: NFrederic Weisbecker <fweisbec@gmail.com> Cc: Hirokazu Takata <takata@linux-m32r.org>
