SONIC interrupt handling
Install the built-in macsonic interrupt handler on both IRQs when using via_alt_mapping. Otherwise the rare interrupt that still comes from the nubus slot will wedge the nubus. $ cat /proc/interrupts auto 2: 89176 via2 auto 3: 744367 sonic auto 4: 0 scc auto 6: 318363 via1 auto 7: 0 NMI mac 9: 119413 framebuffer vbl mac 10: 1971 ADB mac 14: 198517 timer mac 17: 89104 nubus mac 19: 72 Mac ESP SCSI mac 56: 629 sonic mac 62: 1142593 ide0 Version 1 of this patch had a bug where a nubus sonic card would register two interrupt handlers. Only a built-in sonic needs both. Versions 2 and 3 needed some cleanups, as Raylynn Knight and Christoph Hellwig pointed out (thanks).
