Counter question: Why do you need to use math in kernel code? It is
generally a sign something is not well split-up between kernel-based
driver code and user-space RT applications.
To answer your question: No, Xenomai does not come with a kernel math
lib because there is not much use for it - generally. Porting the app to
user-space is recommended.
