From 61a1773e2e01140729f06cd2d2ee9ff83cc1d256 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 4 Mar 2021 17:10:59 -0800 Subject: [PATCH] KVM: x86/mmu: Unexport MMU load/unload functions Unexport the MMU load and unload helpers now that they are no longer used (incorrectly) in vendor code. Opportunistically move the kvm_mmu_sync_roots() declaration into mmu.h, it should not be exposed to vendor code. No functional change intended.
