Hi Thomas,

5.19 had been pretty quiet on the IRQ front. Well, 5.20 is going
unfortunately back to normal with a bang.

The largest item here is the long awaited LoongArch IRQ support, which
comes with a flurry of irqchip updates and ACPI support (fools!).

The rest divides pretty equally between core code update (making the
affinity functions work for UP kernel is the biggest item), new
drivers (LoongArch, Renesas), and some updates (PLIC, stm32, PLIC
again) and the usual churn, just because people like that.

Please pull,

M.

Merge branch irq/misc-5.20 into irq/irqchip-next (2022-07-25 09:45:34 +0100)

----------------------------------------------------------------
irqchip/genirq updates for 5.20:

* Core code update:

- Non-SMP IRQ affinity fixes, allowing UP kernel to behave similarly
to SMP ones for the purpose of interrupt affinity

- Let irq_set_chip_handler_name_locked() take a const struct irq_chip *

- Tidy-up the NOMAP irqdomain API variant

- Teach action_show() to use for_each_action_of_desc()

- Make irq_chip_request_resources_parent() allow the parent callback
to be optional

- Remove dynamic allocations from populate_parent_alloc_arg()

* New drivers:

- Merge the long awaited IRQ support for the LoongArch architecture,
with the provisional ACPICA update (to be reverted once the official
support lands)

- New Renesas RZ/G2L IRQC driver, equipped with its companion GPIO
driver

* Driver updates

- Optimise the hot path operations for the SiFive PLIC, trading the
locking for per-CPU priority masking masking operations which are
apparently faster

- Work around broken PLIC implementations that deal pretty badly with
edge-triggered interrupts. Flag two implementations as affected.

- Simplify the irq-stm32-exti driver, particularly the table that
remaps the interrupts from exti to the GIC, reducing the memory usage

- Convert the ocelot irq_chip to being immutable

- Check ioremap() return value in the MIPS GIC driver

- Move MMP driver init function declarations into the common .h

- The obligatory typo fixes
