  • dc87c3985   libata: honour host controllers that want just one host ... Browse Code »

    The Marvell IDE interface on my machine would hit a BUG_ON() in
    lib/iomem.c because it was calling ata_pci_init_one() specifying just a
    single port on the host, but that would actually end up trying to
    initialize two ports, the second one with bogus information.

    This fixes "ata_pci_init_one()" so that it actually passes down the
    n_ports variable that it got from the low-level driver to the host
    allocation routine ("ata_host_alloc_pinfo()"), which results in the ATA
    layer actually having the correct port number information.

    And in order to make it all work, I also needed to fix a few places that
    had incorrectly hard-coded the fact that a host always had exactly two
    ports (both ata_pci_init_bmdma() and ata_request_legacy_irqs() would
    just always iterate over both ports).

  • 14e38ac82   pm: include EIO from errno-base.h ... Browse Code »

    For backwards compatibility, call_platform_enable_wakeup() can return 0
    instead of -EIO since we aren't guaranteed to have errno defined.

    Add a kvasprintf() function to complement kasprintf().

    No in-tree users yet, but I have some coming up.

  • 9684e51cd   power management: force pm_ops.valid callback to be assigned ... Browse Code »

    This patch changes the docs and behaviour from "all states valid" to "no
    states valid" if no .valid callback is assigned. Users of pm_ops that only
    need mem sleep can assign pm_valid_only_mem without any overhead, others
    will require more elaborate callbacks.

    Now that all users of pm_ops have a .valid callback this is a safe thing to
    do and prevents things from getting messy again as they were before.

  • e8c9c5026   power management: implement pm_ops.valid for everybody ... Browse Code »

    Almost all users of pm_ops only support mem sleep, don't check in .valid and
    don't reject any others in .prepare so users can be confused if they check
    /sys/power/state, especially when new states are added (these would then
    result in s-t-r although they're supposed to be something different).

    This patch implements a generic pm_valid_only_mem function that is then
    exported for users and puts it to use in almost all existing pm_ops.
