It would be helpful to know why you need this support as well
I just wanted to know the idea behind not having FP in kernel-space.
Thanks,

Saving and restoring FPU registers adds overhead to thread context
switching and there has never been a legitimate

So far there has been no compelling reason for having FP
support in kernel code that would justify to pay that
price.

First, FPU emulation is rather slow, and second, someone
would have to write the code. In the past
of the FPU
registers on every context switch within the kernel.

That's nonsense! Floating point arithmetic is absolutely allowed
