  KVM: x86/mmu: Move the misplaced export of kvm_zap_gfn_range() (2025-11-04 09:51:06 -0800)

----------------------------------------------------------------
KVM x86 MMU changes for 6.19:

 - Skip the costly "zap all SPTEs" on an MMIO generation wrap if MMIO SPTE
   caching is disabled, as there can't be any relevant SPTEs to zap.

 - Relocate a misplace export.
