    SubjectFirst steps towards making NO_IRQ a generic concept

    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:// 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.
