[PATCH 1/2] nohz: Fix unavailable tick_stop tracepoint in dynticks idle

[Frederic Weisbecker <fweisbec@gmail.com>]

The trace_tick_stop() tracepoint is only available in full
dynticks. But it's also used by dynticks-idle so let's build
it for the latter config as well.

This fixes:

     kernel/time/tick-sched.c: In function tick_nohz_stop_sched_tick:
     kernel/time/tick-sched.c:644: error: implicit declaration of function trace_tick_stop
     make[2]: *** [kernel/time/tick-sched.o] Erreur 1
