Is it possible to run a 64-bit Linux on a chrome9 chipset onnected to
a 64-bit processor? if so you'll have to fix a lot of these ioctls up.

^^ unsigned long are bad in ioctls, as its undefined size you should use
__u64s in new ioctls and convert them in the kernel.

^^^^^^^^^^^^^^^^^^^ here also unsigned long and pointers.
pointers also change size on 32 vs 64-bit.

pointers again.

more unsignde longs.

and more. I think you can figure out the rest :-)
basically ioctls need defined sizes for 32/64 bit compat.
