[PATCH v2] arm: add RESET_PID in the clone impl

[Waldemar Brodkorb]

Hi Wang,

I have tested your patch for arm/armhf and NPTL. Works fine.
The getpid tests didn't fail anymore.

But when I am trying to compile linuxthreads instead of NPTL I get:

Any idea how to fix the bug without breaking linuxthreads?
