* 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.
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.
