[PATCH 0/4] tracing: export event trace and trace_marker

[Tingwei Zhang]

Ftrace has ability to export trace packets to other destionation. Currently,
only function trace can be exported. This series extends the support to
event trace and trace_maker. STM is one possible destination to export ftrace.
Use seperate channel for each CPU to avoid mixing up packets from different
CPUs together.

Tingwei Zhang (4):
  stm class: ftrace: change dependency to TRACING
  tracing: add trace_export support for event trace
  tracing: add trace_export support for trace_marker
  stm class: ftrace: use different channel accroding to CPU
