Andi Kleen 176df2457e x86_64: Zero extend all registers after ptrace in 32bit entry path. 
Strictly it's only needed for eax.

It actually does a little more than strictly needed -- the other registers
are already zero extended.

Also remove the now unnecessary and non functional compat task check
in ptrace.

This is CVE-2007-4573

Found by Wojciech Purczynski
