Subject: [GIT PULL] KVM: Non-x86 changes for 6.6

Please pull a few smallish KVM-wide changes.  This will conflict with the MMU
pull request, which changed a WARN_ON() to a WARN_ON_ONCE().  The resolution
is pretty straightfoward.

  KVM: Remove unused kvm_make_cpus_request_mask() declaration (2023-08-17 11:59:43 -0700)

----------------------------------------------------------------
Common KVM changes for 6.6:

 - Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier events to pass
   action specific data without needing to constantly update the main handlers.

 - Drop unused function declarations
