You are generally speaking, correct. I am wondering if we don't need to
make exceptions, from time to time. For example, when we can easily
correct general math problems by using something from <linux/math64.h>
that's one thing and should be done.
On the other hand, we have this, which is adding a nice looking font for
the cases where our console is not a serial port but a screen and in
some cases a rather nice high DPI one too. So under the assumption that
no, we can't find a font we can borrow that doesn't also use floating
point, maybe we allow this, BUT with some caveats needing to be added
such as noting that hey, what happens if you 'go' some benchmark that
does FP stuff? Well, it better be save/restoring, yes?
