That would be too weak - it's forbidden, unless you play special arch
dependend tricks to allow it. Some archs do that for their memcpy/memset 
implementations. You will need to explicitly save and restore fpu state
before and after your code and enable/disable the fpu.

Let me ask the other obvious question: why do you implement the neural network
in the kernel?
