The code looks like it's designed to be included from userspace for
testing; as it compiles without this include (and has no other
includes), I chose not to add it.
Linus makes a good point, but someone who actually knows the code
should, y'know, test it and stuff...
It should use kernel_fpu_begin() imho. If someone wants to test
it in user space again they can add dummy definitions of that
to their user space header.
I hadn't seen this thread until now, when Neil pointed me to the thread.
Using kernel_fpu_begin() ... kernel_fpu_end() is probably indeed the best option.
