Id like to do a similar thing on ppc32 and ppc64. It would be good to
make some of this generic before everyone implements it their own way.
Of course the lower level stuff will be arch specific, but some of it
could be the same (like how do we handle ptracing into the area? Do
we COW or do we deny it and fix gdb to unsderstand vsyscalls).
