[PATCH 0/3] coresight: Don't use contextID with PID namespaces

[Mathieu Poirier]

Since the in-kernel value of a PID differs from what is seen from 
PID namespaces, using contextID tracing with PID namespaces makes the
feature confusing to use and potentially subject to leaking out internal
kernel information.

This set returns an error if contextID and PID namespaces are used in
conjunction and gets rid of the vpid-to-pid translation function as it
is no longer needed.

Thanks,
Mathieu
