Previously, Soft_emulate_8xx was called with no implementation, resulting in build failures whenever building 8xx without math emulation. The implementation is copied from arch/ppc to resolve this issue. However, this sort of minimal emulation is not a very good idea other than for compatibility with existing userspaces, as it's less efficient than soft-float and can mislead users into believing they have soft-float. Thus, it is made a configurable option, off by default. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
