Hi Linus,
This series of four patches are the first step towards making NO_IRQ a pervasive concept. It's bundled up in a git tree for your convenience (unless I bodged it up, in which case it's your inconvenience).
git://git.kernel.org/pub/scm/linux/kernel/git/willy/misc-2.6.git no_irq
- Check the irq number is within bounds in the functions which weren't already checking. - Introduce PCI_NO_IRQ and pci_valid_irq() Explicitly initialise pci_dev->irq with PCI_NO_IRQ, allowing us to change the value of PCI_NO_IRQ when all drivers have been audited. - Use pci_valid_irq() instead of a custom NO_IRQ definition. It probably didn't work on half a dozen architectures. - Move the definition of NO_IRQ from asm directories to <linux/hardirq.h>. Individual architectures can still override it if they want to, but all existing definitions were -1.

I'll follow this mail with the patches for other peoples benefits. They were previously posted to linux-arch with no responses. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
