Paolo Bonzini 314b40b3b6 KVM/arm64 changes for 6.17, round #1 
- Host driver for GICv5, the next generation interrupt controller for
    arm64, including support for interrupt routing, MSIs, interrupt
    translation and wired interrupts.
 
  - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
    GICv5 hardware, leveraging the legacy VGIC interface.
 
  - Userspace control of the 'nASSGIcap' GICv3 feature, allowing
    userspace to disable support for SGIs w/o an active state on hardware
    that previously advertised it unconditionally.
 
  - Map supporting endpoints with cacheable memory attributes on systems
    with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
    maintenance on the address range.
 
  - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
    hypervisor to inject external aborts into an L2 VM and take traps of
    masked external aborts to the hypervisor.
 
  - Convert more system register sanitization to the config-driven
    implementation.
 
  - Fixes to the visibility of EL2 registers, namely making VGICv3 system
    registers accessible through the VGIC device instead of the ONE_REG
    vCPU ioctls.
 
  - Various cleanups and minor fixes.
