  Log:
  Revert previous commit. We should not get any FP traps from within
  the kernel. We can guarantee this by resetting the FP status register.
  This masks all FP traps. The reason we did get FP traps was that we
  didn't reset the FP status register in all cases.
  
  Make sure to reset the FP status register in syscall(). This is one of
  the places where it was forgotten.
  
  While on the subject, reset the FP status register only when we trapped
  from user space.
