notably we don't do this for 32-bit kernels.  this means that
de-referencing V_SSP is the right things todo.  sorry for taking so long
to understand this code...

so one last comment nit and then i promise i'm done.  could you update
the the descriptions of the stack setup by BRAND_CALLBACK on 64-bit
kernels to be more accurate for interrupt syscalls by changing:
        "user stack pointer"
        "user (or interrupt) stack pointer"

thanks, and sorry again for the delays while i tried to understand the
code better.


Thanks for all of your comments.  I'll make the update you suggested.

Thanks again,
