I'm tagging generic patches just with "ipipe:". IIRC, this is what
Philippe requested.

I think ipipe_uaccess_might_fault could become a generic service in case
other archs need it as well. And it has to map directly to might_fault
in case CONFIG_IPIPE_DEBUG_CONTEXT is disabled (thus zero overhead).
