From e12b785e52fc26d5456b16d5a6e1968cd1deab41 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 25 Feb 2021 17:03:27 -0800 Subject: [PATCH] KVM: x86/mmu: Use 'end' param in TDP MMU's test_age_gfn() Use the @end param when aging a GFN instead of hardcoding the walk to a single GFN. Unlike tdp_set_spte(), which simply cannot work with more than one GFN, aging multiple GFNs would not break, though admittedly it would be weird. Be nice to the casual reader and don't make them puzzle out why the end GFN is unused. No functional change intended.
