Right you are. Thanks. Maciej gave me a bit of a scare there. ;-)
In an ideal universe, the unmodified FCSR which is correctly
passed as a parameter to handle_fpe() (now that I look at entry.S,
it all comes back.. ;-) would be passed on as part of the
signal "payload" if SIGFPE is caught, but at least things
aren't drastically broken.
