(In reply to Oleksandr Tymoshenko from comment #9)
I do not have a strong opinion there, if you want to commit this, go ahead.

I do find it strange the unused fpu context list, why not simply call
fpu_kern_alloc() as needed ?  I suspect that the cost of allocation is lower
than contending on the mutex.
