If CONFIG_STM_SOURCE_FTRACE is selected, Function trace data can be writen
to sink via STM, all functions that related to writing data packets to
STM should be marked 'notrace' to avoid being traced by Ftrace, otherwise
the program would stall into an endless loop.

Quick nit: can you please split this one in 4: one for Coresight, one
for Intel TH, one for stm/dummy and one for stm/core?

Sure, will do.

I'd like to keep the bisectability. Otherwise, this is fine by me:
