Subject: [PATCH 0/1] perf util: Do not reuse target->per_thread flag 

Hi Arnaldo,

Here is another stab at addressing the side effect introduced by commit
("73c0ca1eee3d perf thread_map: Enumerate all threads from /proc").

I have decided to add another variable to struct target, which keep
things simple and doesn't touch the core.  Another solution could have
been to make target->per_thread an enumaration with values PER_THREAD
and ALL_THREAD, something that could be switched on in function
thread_map__new_str().

I opted for the first option as it makes the code easier to understand.
Let me know what you prefer or get back to me with a better solution if
you see one.

Thanks,
Mathieu
