We already have compat_sys_timer_create. It should be sufficient just
to add the conversion (if anything new is needed) there. The pointer
value can be passed to userland in one or two int fields, I don't really
care. When reporting the event to the user code we cannot just point
into the ring buffer anyway. So while copying the data we can rewrite
it if necessary. I see no need to complicate the code more than it
already is.
