The SOFT_DISABLE_INTS seems an odd name for something that updates the

rename SOFT_DISABLE_INTS with RECONCILE_IRQ_STATE to avoid this confusion.

need to replay an
interrupt, we shouldn't restore that previous backup thread info
to make sure we can replay an interrupt lately with a proper
thread info.
This patch use __check_irq_replay() to guarantee this process.

We always alloc critical/machine/debug check exceptions. This is
different from the normal exception. So we should load these exception

With lazy interrupt, some implementations of hotplug will
get some interrupts even while offline, just ignore these.

In preempt case current arch_local_irq_restore() from
preempt_schedule_irq() may enable hard interrupt but we really
should disable interrupts when we return from the interrupt,
and so that we don't get interrupted after loading SRR0/1.
