s390/vtime: correct system time accounting There is a slight misaccounting of system time in vtime_account_user. This function is called once per HZ tick in interrupt context. The irq_enter function already accounted the system time up to the point of the irq_enter call. The system time from irq_enter until vtime_account_user/do_account_vtime is reached is irq time but it is accounted to the previous context. Just drop the hardirq offset from arch/s390/kernel/vtime.c. Reported-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
