  • ef24ba709   powerpc: Remove all usages of NO_IRQ ... Browse Code »

    NO_IRQ has been == 0 on powerpc for just over ten years (since commit
    0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change
    platforms to use it")). It's also 0 on most other arches.

    Although it's fairly harmless, every now and then it causes confusion
    when a driver is built on powerpc and another arch which doesn't define
    NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least
    some of which are to work around that problem.

    So we'd like to remove it. This is fairly trivial in the arch code, we
    just convert:

    if (irq == NO_IRQ) to if (!irq)
    if (irq != NO_IRQ) to if (irq)
    irq = NO_IRQ; to irq = 0;
    return NO_IRQ; to return 0;

    And a few other odd cases as well.

    At least for now we keep the #define NO_IRQ, because there is driver
    code that uses NO_IRQ and the fixes to remove those will go via other
    trees.

    Note we also change some occurrences in PPC sound drivers, drivers/ps3,
    and drivers/macintosh.

  • 91b6fad5c   powerpc/pmac: Remove early allocation of the SMU command buffer ... Browse Code »

    The SMU command buffer needs to be allocated below 2G using memblock.

    In the past, this had to be done very early from the arch code as
    memblock wasn't available past that point. That is no longer the
    case though, smu_init() is called from setup_arch() when memblock
    is still functional these days. So move the allocation to the
    SMU driver itself.

  • 952bbcb07   PCI: Remove includes of asm/pci-bridge.h ... Browse Code »

    Drivers should include asm/pci-bridge.h only when they need the arch-
    specific things provided there. Outside of the arch/ directories, the only
    drivers that actually need things provided by asm/pci-bridge.h are the
    powerpc RPA hotplug drivers in drivers/pci/hotplug/rpa*.

    Remove the includes of asm/pci-bridge.h from the other drivers, adding an
    include of linux/pci.h if necessary.

    ppc has special instruction forms to efficiently load and store values

    {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h.

    However, gcc is perfectly capable of generating the byte-reversing
    load/store instructions when using the normal, generic cpu_to_le*() and
    le*_to_cpu() functions eaning the arch-specific functions don't have much
    point.

    Worse the "le" in the names of the arch specific functions is now
    misleading, because they always generate byte-reversing forms, but some
    ppc machines can now run a little-endian kernel.

    To start getting rid of the arch-specific forms, this patch removes them
    from all the old Power Macintosh drivers, replacing them with the
    generic byteswappers.

    Pull powerpc updates from Ben Herrenschmidt:
    "So here's my next branch for powerpc. A bit late as I was on vacation
    last week. It's mostly the same stuff that was in next already, I
    just added two patches today which are the wiring up of lockref for
    powerpc, which for some reason fell through the cracks last time and
    is trivial.

    The highlights are, in addition to a bunch of bug fixes:

    - Reworked Machine Check handling on kernels running without a
    hypervisor (or acting as a hypervisor). Provides hooks to handle
    some errors in real mode such as TLB errors, handle SLB errors,
    etc...

    - Support for retrieving memory error information from the service
    processor on IBM servers running without a hypervisor and routing
    them to the memory poison infrastructure.

    - _PAGE_NUMA support on server processors

    - 32-bit BookE relocatable kernel support

    - FSL e6500 hardware tablewalk support

    - A bunch of new/revived board support

    - FSL e6500 deeper idle states and altivec powerdown support

    You'll notice a generic mm change here, it has been acked by the
    relevant authorities and is a pre-req for our _PAGE_NUMA support"
