[PARISC] remove remnants of parisc-specific softirq code
Kyle, This patch removes remnants of softirq support that we no longer need. I suspect this was just overlooked when willy convert parisc to generic IRQ support. Tested on c3600 32-bit UP. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> [and tested on a c8000 64-bit SMP --kyle] Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
