RFC 1/1 parisc sys_ptrace prototype

parisc has a different prototype for ptrace in that it passes the pid as pid_t, not as long. This doesn't matter on 32bit architectures because both are 32bit, but it's different for 64bit kernel.

OTOH I've heard 64bit parisc userland is mostly non-existant so maybe we could still fix this, greatly simplifying a later ptrace consolidation.
