The SPARC code has been extensively reviewed and tested over the years with a
recent focus due to the SMP. It does clear the DISPATCH_NEEDED flag but it has
already made a decision to to the _ISR_Dispatch at that point.

I think it would be helpful if you could try to compare the logic of the
blackfin version of that vs the sparc.

The ARM or PowerPC should also be good references if you find those easier to
compare.
