    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://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.

    drivers/pci/probe.c | 7 +++++--
    drivers/pcmcia/pd6729.c | 6 +-----
    include/asm-arm/irq.h | 8 --------
    include/asm-arm26/irq.h | 8 --------
    include/asm-frv/irq.h | 3 ---
    include/asm-parisc/irq.h | 2 --
    include/asm-powerpc/irq.h | 3 ---
    include/linux/hardirq.h | 10 ++++++++++
    include/linux/pci.h | 9 +++++++++
    kernel/irq/manage.c | 15 +++++++++++++++

    I'll follow this mail with the patches for other peoples benefits. They
    were previously posted to linux-arch with no responses.
