Merge branch irq/irqdomain-locking into irq/irqchip-next

* irq/irqdomain-locking:
  : .
  : irqdomain locking overhaul courtesy of Johan Hovold.
  :
  : From the cover letter:
  :
  : "Parallel probing (e.g. due to asynchronous probing) of devices that
  : share interrupts can currently result in two mappings for the same
  : hardware interrupt to be created.
  :
  : This series fixes this mapping race and reworks the irqdomain locking so
  : that in the end the global irq_domain_mutex is only used for managing
  : the likewise global irq_domain_list, while domain operations (e.g. IRQ
  : allocations) use per-domain (hierarchy) locking."
