Linus Torvalds 4527e83780 Updates for the MSI interrupt subsystem and RISC-V initial MSI support:
- Core and platform-MSI
 
     The core changes have been adopted from previous work which converted
     ARM[64] to the new per device MSI domain model, which was merged to
     support multiple MSI domain per device. The ARM[64] changes are being
     worked on too, but have not been ready yet. The core and platform-MSI
     changes have been split out to not hold up RISC-V and to avoid that
     RISC-V builds on the scheduled for removal interfaces.
 
     The core support provides new interfaces to handle wire to MSI bridges
     in a straight forward way and introduces new platform-MSI interfaces
     which are built on top of the per device MSI domain model.
 
     Once ARM[64] is converted over the old platform-MSI interfaces and the
     related ugliness in the MSI core code will be removed.
 
   - Drivers:
 
     - Add a new driver for the Andes hart-level interrupt controller
 
     - Rework the SiFive PLIC driver to prepare for MSI suport
 
     - Expand the RISC-V INTC driver to support the new RISC-V AIA
       controller which provides the basis for MSI on RISC-V
 
     - A few fixup for the fallout of the core changes.
 
     The actual MSI parts for RISC-V were finalized late and have been
     post-poned for the next merge window.
