 * Linux saves the floating-point registers according to the ISA Linux is
 * executing on, as opposed to the ISA the user program is compiled for.  This
 * is necessary for a handful of esoteric use cases: for example, userpsace
 * threading libraries must be able to examine the actual machine state in
 * order to fully reconstruct the state of a thread.
