[S390] profile_tick called twice
profile_tick is called twice for every clock comparator interrupt. The generic clock event code does it in tick_sched_timer and the s390 backend code in clock_comparator_work. That is one too many, remove the one in the arch backend code. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
