Subject: [PATCH 0/3] ARM Coresight: Enhance ETM tracing control

Usage of ETM tracing facility is currently very limited: user can
only start/stop tracing. This set of patches enables management of
address combinations and PIDs that trigger tracing.

ETM management was done via sysfs entries (trace_info,
trace_running...), this code adds trace_addrrange and trace_pid to
let the user read/write custom values.

This series of patches apply to v3.13-rc2.
