perf tools: change machine__findnew_thread() to set thread pid
Add a new parameter for 'pid' to machine__findnew_thread(). Change callers to pass 'pid' when it is known. Note that callers sometimes want to find the main thread which has the memory maps. The main thread has tid == pid so the usage in that case is: machine__findnew_thread(machine, pid, pid) whereas the usage to find the specific thread is: machine__findnew_thread(machine, pid, tid) Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: David Ahern <dsahern@gmail.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1377591794-30553-2-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
