  28 # On x86_32, register frame is passed verbatim on stack as struct
  29 # pt_regs.  gcc considers the parameter to belong to the callee and
  30 # with -fstack-protector it copies pt_regs to the callee's stack frame
  31 # to put the structure after the stack canary causing changes made by
  32 # the exception handlers to be lost.  Turn off stack protector for all
  33 # files containing functions which take struct pt_regs from register
  34 # frame.
  35 #
  36 # The proper way to fix this is to teach gcc that the argument belongs
  37 # to the caller for these functions, oh well...
