Linus Torvalds 0b29600a30 Updates for interrupt chip drivers:
- Add support of forced affinity setting to yet offline CPUs for the
    MIPS-GIC to ensure that the affinity of per CPU interrupts can be set
    during the early bringup phase of a secondary CPU in the hotplug code
    before the CPU is set online and interrupts are enabled.\
 
  - Add support for the MIPS (RISC-V !?!?) P8700 SoC in the ACLINT_SSWI
    interrupt chip
 
  - Make the interrupt routing to RISV-V harts specification compliant so it
    supports arbitrary hart indices
 
  - Add a command line parameter and related handling to disable the generic
    RISCV IMSIC mechanism on platforms which use a trap-emulated IMSIC.
    Unfortunatly this is required because there is no mechanism available to
    discover this programatically.
 
  - Enable wakeup sources on the Renesas RZV2H driver
 
  - Convert interrupt chip drivers, which use a open coded variant of
    msi_create_parent_irq_domain() to use the new functionality
 
  - Convert interrupt chip drivers, which use the old style two level
    implementation of MSI support over to the MSI parent mechanism to
    prepare for removing at least one of the three PCI/MSI backend variants.
 
  - The usual cleanups and improvements all over the place
