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.
