[PATCH 0/5] irq: Reorder time handling against HARDIRQ_OFFSET on IRQ entry v3

[Frederic Weisbecker]

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.

      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
