This short series introduces fixes of 2 observed isues (#1 & #2) in clone()
syscall in ARC port and one enhancement (#3).

It all started from failing tst-clone1 in uClibc testsuite and during
its debugging we observed another quite subtle issue which was then not only
solved but better (which means shorter and simpler) implementation was made.

Alexey Brodkin (3):
  arc: clone: Recover PID correctly
  arc: clone: Fix CLONE_THREAD detection
  arc: clone: Simplify CLONE_THREAD detection
