I'm pretty sure this isn't about changing cs or far jumps
I think Indan means code is running with 64-bit cs, but the kernel
treats int $0x80 as a 32-bit syscall and sysenter as a 64-bit syscall,
and there's no way for the ptracer to know which syscall the kernel
will perform, even by looking at all registers. It looks like a hole
in ptrace which could be fixed.
