I did most of the OpenRISC conversion last weekend... the
kernel_thread bits work fine but I end up with the init thread dying
with what I've got now for kernel_execve.  Once I've got that sorted
out, I'll pass this along to you.

Thanks for the above explanation... it took me a good while to wrap my
head around how this was supposed to work from reading through the
arch's that you had already converted.  All in all, though, I find
it's a nice cleanup and, conceptually, an improvement over what we had
before.

Thanks,
Jonas
