Linus Torvalds ac7473a179 Updates for the interrupt subsystem:
- Core:
 
     - Provide a new mechanism to create interrupt domains. The existing
       interfaces have already too many parameters and it's a pain to expand
       any of this for new required functionality.
 
       The new function takes a pointer to a data structure as argument. The
       data structure combines all existing parameters and allows for easy
       extension.
 
       The first extension for this is to handle the instantiation of
       generic interrupt chips at the core level and to allow drivers to
       provide extra init/exit callbacks.
 
       This is necessary to do the full interrupt chip initialization before
       the new domain is published, so that concurrent usage sites won't see
       a half initialized interrupt domain. Similar problems exist on
       teardown.
 
       This has turned out to be a real problem due to the deferred and
       parallel probing which was added in recent years.
 
       Handling this at the core level allows to remove quite some accrued
       boilerplate code in existing drivers and avoids horrible workarounds
       at the driver level.
 
     - The usual small improvements all over the place
 
   - Drivers
 
     - Add support for LAN966x OIC and RZ/Five SoC
 
     - Split the STM ExtI driver into a microcontroller and a SMP version to
       allow building the latter as a module for multi-platform kernels.
 
     - Enable MSI support for Armada 370XP on platforms which do not support
       IPIs.
 
     - The usual small fixes and enhancements all over the place.
