Semaphore signalling works similarly to previous GENs with the exception
that the per ring mailboxes no longer exist. Instead you must define
your own space, somewhere in the GTT.
The comments in the code define the layout I've opted for, which should
be fairly future proof. Ie. I tried to define

We have an igt to exercise tlb invalidation stuff
