Subject[RFC PATCH 0/2] KVM: arm64: Host/Guest trace syncronization
Date
This small series introduces the necessary infrastructure to be able to
syncronize host and guest traces. The approach I'm following is a bit
biased since I tried to replicate the methods I've been using in the
past with x86.

This was tested on an Ampere Mt. Jade based machine.
