From 31f6e3832a0f1c366e54033335aed2375f6e447a Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 1 Aug 2022 07:27:18 -0400 Subject: KVM: x86/mmu: remove unused variable The last use of 'pfn' went away with the same-named argument to host_pfn_mapping_level; now that the hugepage level is obtained exclusively from the host page tables, kvm_mmu_zap_collapsible_spte does not need to know host pfns at all.
