From 38f703663d4c82ead5b51b8860deeef19d6dcb6d Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 27 Jul 2021 12:32:51 +0200 Subject: [PATCH] KVM: arm64: Count VMID-wide TLB invalidations KVM/ARM has an architecture-specific implementation of kvm_flush_remote_tlbs; however, unlike the generic one, it does not count the flushes in kvm->stat.remote_tlb_flush, so that it inexorably remained stuck to zero.
