Subject: [PATCH 0/5] coresight: Support context-ID tracing when PID namespace is enabled

The Coresight ETM drivers already support context-ID tracing, but it won't
work when PID namespace is enabled. This is because when using PID
namespace a process id (ie. VPID) seen from the current namespace differs
from the id (ie. PID) seen by kernel.

This patch-set does add a translation between VPID and PID.

Chunyan Zhang (5):
  coresight-etm3x: Change the name of the ctxid_val to ctxid_pid
  coresight-etm4x: Change the name of the ctxid_val to ctxid_pid
  Coresight: Add an interface for supporting ETM3/4 Context ID tracing
  coresight-etm3x: Support context-ID tracing when PID namespace is
    enabled
  coresight-etm4x: Support context-ID tracing when PID namespace is
    enabled
