Without the patch, I am able to reproduce unexpected FP exceptions in linker (ld) during the SMP compilation (make -j3 on 2-way SS20). With the patch they are gone. I found it in the 2.4 kernel, but the buggy code is the same in 2.4 and 2.6 so I suspect that 2.6 needs it too. It is maybe not so critical now, but it definitely adds to stability of 32-bit SPARC SMP. Regards, Krzysztof
