drivers/infinband is W=1 clean right now in linux-next

But how can I build *only* drivers/infiniband using W=1 so I can keep
it that way?

The rest of the kernel is not clean and creates too much warning noise
to be usable, even with my mini config.

Just doing a 'make W=1 drivers/infiniband' is sort of OK, but then I
end up compiling things twice

Does anyone know a good solution?

Jason
