  s390: fix test_fp_ctl inline assembly contraints
  
  The test_fp_ctl function is used to test if a given value is a valid
  floating-point control. The inline assembly in test_fp_ctl uses an
  incorrect constraint for the 'orig_fpc' variable. If the compiler
  chooses the same register for 'fpc' and 'orig_fpc' the test_fp_ctl()
  function always returns true. This allows user space to trigger
  kernel oopses with invalid floating-point control values on the
  signal stack.
  
  This problem has been introduced with git commit 4725c86055f5bbdcdf
  "s390: fix save and restore of the floating-point-control register"
