ioctl on x32 runs through the compat_sys_ioctl entry point like x86.  attached 
is the generated header -- ioctls_arch.h was the same as x86_64/ioctls_arch0.h.

one thing to note with the tracing of the ioctl ABI is that the kernel might be 
broken and need fixing in some cases.  x32 is not widely deployed, so it hasn't 
been fully vetted yet :).
