Add a ptrace interface to allow collecting an execution trace
of the traced task.
This collects control flow changes in a (cyclic) buffer and allows
debuggers to fill in the gaps and show an execution trace of the debuggee.
This adds a ptrace interface to the hardware's branch trace store.
Debuggers may use it to collect an execution trace of the debugged
application in order to answer the question 'how did I get here?'.
Debuggers may trace user mode as well as kernel mode.
Say Y unless there is no application development on this machine
and you want to save a small amount of code size.
