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: Ingo Molnar <mingo@elte.hu> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Hirokazu Takata <takata@linux-m32r.org>

274 This option reduces the latency of the kernel when reacting to
275 real-time or interactive events by allowing a low priority process to
276 be preempted even if it is in kernel mode executing a system call.
277 This allows applications to run more reliably even when the system is
278 under load.

280 Say Y here if you are building a kernel for a desktop, embedded
281 or real-time system. Say N if you are unsure.
