It's basically ready to be merged - but it's triggering issues elsewhere
in the kernel which I have to resolve first.

The short version is that the memory special mapping created by uprobe
with VM_EXEC but not VM_READ permissions is not working but it's working
if I add VM_READ.  That should not be necessary so something deep down
in the guts of arch/mips is wrong.
