two different sets, the general register set (gregset) and the floating
point register set (fpregset). For each set, there is an ioctl to get
the current register set and another ioctl to set the current values.
The actual structure passed through the ioctl interface is, of course,
naturally machine dependent, and is different for each set of registers.
