* Yu-cheng Yu:
Like other arch_prctl()'s, this parameter was 'unsigned long' earlier. The idea was, since this arch_prctl is only implemented for the 64-bit kernel, we wanted it to look as 64-bit only. I will change it back to 'unsigned long'.
What about x32? In general, long is rather problematic for x32. Thanks, Florian

The problem is the size of 'long', right? Because this parameter is passed in a register, and only the lower bits are used, x32 works as well.
