Since commit:
58122bf1d8 ("x86/fpu: Default eagerfpu=on on all CPUs")
... in Linux 4.6, eager FPU mode has been the default on all x86
systems, and no one has reported any regressions.
This patch removes the ability to enable lazy mode: use_eager_fpu()
becomes "return true" and all of the FPU mode selection machinery is
removed.
