Have you tested this with (upcoming) GCC 5.0?  GCC now uses CR5,
and it likes to use it very much, it might be more convenient to
use e.g. CR1 (which is allocated almost last, only before CR0).

No. I did not try it with GCC5.0 But I did force kernel compilation with
fixed-cr5 which should make GCC avoid using CR5. But i will try that today.

It should work just fine, but testing is always useful, because, you know,
"should".  Thanks.
