Oh, and all those games with

   #define __EXTERN_INLINE
   #include <asm/io.h>
   #include <asm/jensen.h>
   #undef  __EXTERN_INLINE

don't actually work, because there's the usual multiple-inclusion
protection on top of asm/jensen.h:

   #ifndef __ALPHA_JENSEN_H
   #define __ALPHA_JENSEN_H

and this include of <asm/jensen.h> is entirely unused, because we
ended up getting the one *without* that empty __EXTERN_INLINE #define
from an earlier include of

  #include <linux/interrupt.h>

that caused asm/io.h and asm/jensen.h to be included earlier.

The *other* machine files know to do their includes at the top of the file.

But then I end up getting

     ERROR: modpost: "__udiv_qrnnd" [lib/mpi/mpi.ko] undefined!

because CONFIG_MATHEMU wasn't set and the crypto stuff wants the MPI code.

So there seems to be other alpha Kconfig issues in there, and they
aren't all actually Jensen-specific.

Oh well. I guess can fix things up, since I did get tthe
cross-compiler environment..
