Slightly different design this time. As per Peter and Thomas reviews and
suggestions, use the following layout:
account_softirq_enter() -> irqtime_account_irq(curr, SOFTIRQ_OFFSET);
account_softirq_exit() -> irqtime_account_irq(curr, 0);
account_hardirq_enter() -> irqtime_account_irq(curr, HARDIRQ_OFFSET);
account_hardirq_exit() -> irqtime_account_irq(curr, 0);
So now the preempt count offset is substracted in the cputime dispatch
function and the resulting code is better consolidated.

Frederic Weisbecker (5):
sched/cputime: Remove symbol exports from IRQ time accounting
s390/vtime: Use the generic IRQ entry accounting
sched/vtime: Consolidate IRQ time accounting
irqtime: Move irqtime entry accounting after irq offset incrementation
irq: Call tick_irq_enter() inside HARDIRQ_OFFSET
