This patchset makes the ETMv4 driver usable from Perf by way of the recently added AUX area functionality. The first 7 patches move code around to obtain a configuration granularity suitable for Perf. The last patch implement the AUX area API. Most of the code is made to resemble the work that was done on ETMv3 as much as possible.
