Using -msoft-float when compiling the kernel and/or kernel modules is a
_requirement_!  We've hit too many user data integrity errors due to
third party modules not being compiled with -msoft-float, which is why
I changed the kernel src to force a panic if we take a FP Unavailable
exception within the kernel.
