      * kvm-arm64/vgic-sre-traps:
        : .
        : Fix the multiple of cases where KVM/arm64 doesn't correctly
        : handle the guest trying to use a GICv3 that isn't advertised.
        :
        : From the cover letter:
        :
        : "It recently appeared that, when running on a GICv3-equipped platform
        : (which is what non-ancient arm64 HW has), *not* configuring a GICv3
        : for the guest could result in less than desirable outcomes.
        :
        : We have multiple issues to fix:
        :
        : - for registers that *always* trap (the SGI registers) or that *may*
        :   trap (the SRE register), we need to check whether a GICv3 has been
        :   instantiated before acting upon the trap.
        :
        : - for registers that only conditionally trap, we must actively trap
        :   them even in the absence of a GICv3 being instantiated, and handle
        :   those traps accordingly.
        :
        : - finally, ID registers must reflect the absence of a GICv3, so that
        :   we are consistent.
        :
        : This series goes through all these requirements. The main complexity
        : here is to apply a GICv3 configuration on the host in the absence of a
        : GICv3 in the guest. This is pretty hackish, but I don't have a much
        : better solution so far.
        :
        : As part of making wider use of of the trap bits, we fully define the
        : trap routing as per the architecture, something that we eventually
        : need for NV anyway."
        : .
        KVM: arm64: selftests: Cope with lack of GICv3 in set_id_regs
        KVM: arm64: Add selftest checking how the absence of GICv3 is handled

        KVM: arm64: Make most GICv3 accesses UNDEF if they trap
        KVM: arm64: Honor guest requested traps in GICv3 emulation
        KVM: arm64: Add trap routing information for ICH_HCR_EL2

        KVM: arm64: Zero ID_AA64PFR0_EL1.GIC when no GICv3 is presented to the guest

      rebalance_work was keying off of the presence of rebelance_opts in the
      extent - but that was incorrect, we keep those around after rebalance
      for indirect extents since the inode's options are not directly
