Chuck Ebbert b1daec3089 [PATCH] i386: fix incorrect FP signal code 
i386 floating-point exception handling has a bug that can cause error
code 0 to be sent instead of the proper code during signal delivery.

This is caused by unconditionally checking the IS and c1 bits from the
FPU status word when they are not always relevant.  The IS bit tells
whether an exception is a stack fault and is only relevant when the
exception is IE (invalid operation.) The C1 bit determines whether a
stack fault is overflow or underflow and is only relevant when IS and IE
are set.
