Thomas Gleixner 779fda86bd 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
