From 501b918525efec2e701e806f04d474d7da350962 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 25 Mar 2021 19:19:48 -0700 Subject: KVM: Move arm64's MMU notifier trace events to generic code Move arm64's MMU notifier trace events into common code in preparation for doing the hva->gfn lookup in common code. The alternative would be to trace the gfn instead of hva, but that's not obviously better and could also be done in common code. Tracing the notifiers is also quite handy for debug regardless of architecture. Remove a completely redundant tracepoint from PPC e500.
