genirq: Add chip suspend and resume callbacks

2011-04-23T13:56:24+00:00

These callbacks are only called in the syscore suspend/resume code on
interrupt chips which have been registered via the generic irq chip
mechanism. Calling those callbacks per irq would be rather icky, but
with the generic irq chip mechanism we can call this per registered
chip.

genirq: Implement a generic interrupt chip

2011-04-23T13:56:24+00:00

Implement a generic interrupt chip, which is configurable and is able
to handle the most common irq chip implementations.

genirq: Support per-IRQ thread disabling.

2011-04-23T13:56:24+00:00

This adds support for disabling threading on a per-IRQ basis via the IRQ
status instead of the IRQ flow, which is necessary for interrupts that
don't follow the natural IRQ flow channels, such as those that are
virtually created.

The new APIs added are simply:

	irq_set_thread()
	irq_set_nothread()

which follow the rest of the IRQ status routines.

Chained handlers also have IRQ_NOTHREAD set on them automatically, making
the lack of threading explicit rather than implicit. Subsequently, the
nothread flag can be viewed through the standard genirq debugging
facilities.
