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.Signed-off-by: Wu Zhangjin

LOONGSON2_PERFCNT_IRQ is used for the irq number of the performance
overflow interrupts; LOONGSON_PERFCNT_IRQ is unused so remove it.Signed-off-by: Wu Zhangjin

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.Signed-off-by: Wu Zhangjin

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().Signed-off-by: Wu Zhangjin

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.Signed-off-by: Wu Zhangjin

Lemote have used the PMON_VER strings to indicate the loongson-2f
machine series:PMON_VER=LM8089 Lemote 8.9'' netbook
LM8101 Lemote 10.1'' netbook
(The above two netbooks have the same kernel support)
LM6XXX Lemote FuLoong(2F) box series
LM9XXX Lemote LynLoong PC seriesBefore the machtype is supported by the PMON, we can get the machine
type from the PMON_VER for these machines, this will help the users a
lot.Signed-off-by: Wu Zhangjin

Before putting the Loongson 2F into wait mode, suspend the MFGPT Timer and
after wake-up resume it. This may save some power.Signed-off-by: Wu Zhangjin

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.Signed-off-by: Wu Zhangjin

Kernel support for this machine is almost the same as Fuloong 2F; the only
difference is that it uses the serial port provided by Loongson 2F processor

Lemote Loongson 2F family machines need an external interrupt to wake the
system from the suspend mode.For YeeLoong 2F and Mengloong 2F setup the keyboard interrupt as the wakeup
interrupt.The new Fuloong 2F and LingLoong 2F have a button to directly send an
interrupt to the CPU so there is no need to setup an interrupt.Signed-off-by: Wu Zhangjin

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.
