    [PATCH] i386: Ignore masked FPU exceptions · 33333373
    Chuck Ebbert authored
    Masked FPU exceptions should obviously not happen in the first place,
    but if they do, ignoring them seems to be the right thing to do.
    
    Although there is no documentation available for Cyrix MII, I did find
    erratum F-7 for Winchip C6, "FPU instruction may result in spurious
    exception under certain conditions" which seems to indicate that this
    can happen.
    
    That would also explain the behaviour Ondrej Zary reported on the MII.
