55fa9889ca MIPS: loongson: lemote-2f: irq: Make internal data static
Make internal static to eliminate the following sparse warnings:
warning: symbol 'ip6_irqaction' was not declared. Should it be static?
warning: symbol 'cascade_irqaction' was not declared. Should it be static?

7034228792 MIPS: Whitespace cleanup.
Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

77cbece767 MIPS: Loongson: Mark cascade interrupts IRQF_NO_THREAD
There are two cascade interrupts in Loongson machines, one for bonito
northbridge, another for the 8259A controller in the southbridge. Both
want to be non threaded.

e608aadd17 MIPS: Loongson: Remove unused macro LOONGSON_PERFCNT_IRQ
LOONGSON2_PERFCNT_IRQ is used for the irq number of the performance
overflow interrupts; LOONGSON_PERFCNT_IRQ is unused so remove it.

de3bc0e7ba MIPS: Loongson: Oprofile: add a new do_perfcnt_IRQ()
On FuLoong-2F IP6 is shared by the performance counter overflow interrupt
and the Bonito northbridge interrupt.  To reduce overhead only call
do_IRQ() when oprofile is enabled to reduce overhead.

This patch adds an inline function do_perfcnt_IRQ() to hide the #if's ,
which can be shared by the other Loongson machines, i.e. gdium.

b8c7428af0 MIPS: Loongson: Remove set_irq_trigger_mode()
set_irq_trigger_mode() is not needed on all platforms so remove it
and move the related source code to mach_init_irq().

This will allow gdium to share the common irq.c without adding an empty
set_irq_trigger_mode().

922010ff7b MIPS: oprofile: Fix breakage when CONFIG_OPROFILE=m
When the oprofile is compiled as a module do_IRQ() is not called in
arch/mips/loongson/lemote-2f/irq.c due to a wrong #ifdef there.

cb1ed9e117 MIPS: Yeeloong 2F: Add LID open event as the wakeup event
Yeeloong 2F netbook has an KB3310B embedded controller to manage the LID
action.  When the LID is closed or opened a SCI interrupt is sent out and
the corresponding event is saved to an EC register for later query.

Allow the LID open interrupt to wake the processor from wait mode if it is
in the suspend mode.

6616db78ee MIPS: Lemote 2F: Add IRQ support
The generic i8259_irq() will make kernel hang on booting, so Loongson 2F
needs its own polling method.

IP6 is shared by the bonito interrupt and perfcounter interrupts.
