-----------------------------+-----------------------------
 The uniprocessor floating point context switching is unsafe, e.g. it is
 possible to silently corrupt the floating point context.  The SMP floating
 point switching is safe, however, it doesn't use a deferred switch.
 Implement lazy floating point switching in uniprocessor configurations.
 This fixes test case spcontext01.
