Use the trigger type in irq_data and check level type instead of
looking at desc->handle_irq.

The only subtle difference is that alpha uses ACTUAL_NR_IRQS and
prints the IRQF_DISABLED flag.
Change the generic implementation to deal with ACTUAL_NR_IRQS if
defined.
The IRQF_DISABLED printing is pointless, as we nowadays run all
interrupts with irqs disabled.

Reorder
irq_set_chip()
irq_set_chip_data()
irq_set_handler()
to
irq_set_chip()
irq_set_handler()
irq_set_chip_data()
so the next patch can combine irq_set_chip() and irq_set_handler() to
irq_set_chip_and_handler().
Automated conversion with coccinelle.

Avoid the whole lazy disable dance in the demux handler by providing a
irq_disable() callback.
Use the proper accessor functions and tidy up gpio_irq_handler()

Make use of the new functionality which ensures that irq_set_type is
called with the chip masked. Unmask is only done when the interrupt is
not disabled.
Retrieve the trigger type from irq_data in unmask

Use the proper accessor function instead of fiddling in the status
bits directly.

Remove the open coded access to irq_desc which will fail on sparse irq
and use the proper wrappers.

The conversion missed, that one of the irq functions is called from
the init code. Split it out, so the irq number based call works.

commit 9eac6d0 (ARM: Remove dependency of plat-orion GPIO code on mach
directory includes) missed to convert one instance of
DOVE_GPIO_VIRT_BASE and left the orion_gpio_init() in mpp.c
Fix it up.

This is needed for determining the reason for failure when a softdog
timeout occurs.
We use softdog to watch for critical application failures and at the
minimum a snapshot of the system would help to determine the cause. In
such a scenario the application could fail but there isn't a softlockup as
such, hence the detect softlockup feature does not help.
The patch adds a module parameter soft_panic which when set to 1 causes
softdog to invoke panic instead of reboot when the softdog timer expires.
By invoking panic we execute kdump if it is configured and the vmcore
generated by kdump should provide atleast a minimal idea of the reason for
failure.

Fix section mismatch warning:
Mark the called nv_tco_getdevice() as __devinit, just like its caller.
WARNING: drivers/watchdog/nv_tco.o(.devinit.text+0x16): Section mismatch in reference from the function nv_tco_init() to the function .init.text:nv_tco_getdevice()
The function __devinit nv_tco_init() references
a function __init nv_tco_getdevice().
If nv_tco_getdevice is only used by nv_tco_init then
annotate nv_tco_getdevice with a matching annotation.

We should check if we can use that reading out. BIOS could just program wrong address there.
