Marc Zyngier 046a6ee234 irqchip: Bulk conversion to generic_handle_domain_irq()
Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

Qing Zhang b2c4c3969f irqchip/loongson-liointc: irqchip add 2.0 version
Add IO interrupt controller support for Loongson-2K1000, different
from the Loongson-3A series is that Loongson-2K1000 has 64 interrupt
sources, 0-31 correspond to the device tree liointc0 device node, and
the other correspond to liointc1 node.

Qing Zhang 76e0c88dbd MIPS: Loongson64: Move loongson_system_configuration to loongson.h
The purpose of separating loongson_system_configuration from boot_param.h
is to keep the other structure consistent with the firmware.

Jiaxun Yang be09ef09e2 irqchip: loongson-liointc: Workaround LPC IRQ Errata
The 1.0 version of that controller has a bug that status bit
of LPC IRQ sometimes doesn't get set correctly.

So we can always blame LPC IRQ when spurious interrupt happens
at the parent interrupt line which LPC IRQ supposed to route
to.
