[PATCH 10/13] KVM: x86/mmu: Drop repeated add() of to-be-invalidated range

From: Sean Christopherson
Date: Thu Sep 21 2023 - 16:56:47 EST


Use kvm_unmap_gfn_range() instead of kvm_mmu_unmap_gfn_range() when
handling memory attribute ranges now that common KVM adds the target range
to the invalidation set, i.e. calls kvm_mmu_invalidate_range_add() before
invoking the arch callback.
