That's not what I meant. If we are going to allow this particular
device driver to use FPU in kernel, why not another? I mean, what if
someone else wants to use FPU in his XXX driver for whatever reason?
That's what I meant by "not scale". IOW, the proposed "solution" does
not scale to multiple instances of such FPU-requiring drivers.

AS LONG AS there's no other driver which wants to use FPU.
I think the idea of letting a device driver use FPU since there's
currently no other such thing just stinks.
