  • 532a6086e   virtio_balloon: fix towards_target when deflating balloon ... Browse Code »

    Both v and vb->num_pages are u32 and unsigned int respectively. If v is less
    than vb->num_pages (and it is, when deflating the balloon), the result is a
    very large 32-bit number. Since we're returning a s64, instead of getting the
    same negative number we desire, we get a very large positive number.

    This handles the case where v < vb->num_pages and ensures we get a small,
    negative, s64 as the result.

    Rusty: please push this for 2.6.27-rc4. It's probably appropriate for the
    stable tree too as it will cause an unexpected OOM when ballooning.

  • 83097aca8   Fix oops in acer_wmi driver (acer_wmi_init) ... Browse Code »

    The acer_wmi driver does a DMI scan for quirks, and then sets flags into the
    "interface" datastructure for some cases. However, the quirks happen real early
    before "interface" is per se initialized from NULL.

    The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the
    end, when "interface" has it's final value.

  • b15b3ebae   libata: Fix a large collection of DMA mode mismatches ... Browse Code »

    Dave Müller sent a diff for the pata_oldpiix that highlighted a problem
    where a lot of the ATA drivers assume dma_mode == 0 means "no DMA" while
    the core code uses 0xFF.

    This turns out to have other consequences such as code doing >= XFER_UDMA_0
    also catching 0xFF as UDMAlots. Fortunately it doesn't generally affect
    set_dma_mode, although some drivers call back into their own set mode code
    from other points.

    Having been through the drivers I've added helpers for using_udma/using_mwdma
    dma_enabled so that people don't open code ranges that may change (eg if UDMA8
    appears somewhere)

    Thanks to David for the initial bits
    [and added fix for pata_oldpiix from and signed-off-by Dave Mueller

  • 20e2de4a5   ahci: sis controllers actually can do PMP ... Browse Code »

    SIS controllers were blacklisted for PMP as enabling it made device
    detection fail whether the device was PMP or not - the natural
    conclusion was the controller chokes on SRST w/ pmp==15. However, it
    turned out that the controller just didn't like issuing SRST after
    hardreset w/o clearing SError first. Interestingly, the SRST itself
    succeeds but the following commands fail.

    If SError is cleared between hardreset and SRST, which is the default
    behavior now, everything works fine and SIS controllers work with PMPs
    happily.

    Remove PMP blacklisting for SIS AHCIs.

    tf_load for pata_via. This patch cleans it up a bit.

    * Instead of duplicating whole body, copy tf and set ATA_TFLAG_DEVICE
    when necessary.

    * Rename via_ata_tf_load() to via_tf_load().

    * No need to set .tf_load in via_port_ops_noirq as it inherits from
    via_port_ops.

    * Clean up indentation.

  • d127ea7b8   libata: restore SControl on detach ... Browse Code »

    Save SControl during probing and restore it on detach. This prevents
    adjustments made by libata drivers to seep into the next driver which
    gets attached (be it a libata one or not).

    It's not clear whether SControl also needs to be restored on suspend.
    The next system to have control (ACPI or kexec'd kernel) would
    probably like to see the original SControl value but there's no
    guarantee that a link is gonna keep working after SControl is adjusted
    without a reset and adding a reset and modified recovery cycle soley
    for this is an overkill. For now, do it only for detach.

  • 5dbfc9cb5   libata: always do follow-up SRST if hardreset returned -EAGAIN ... Browse Code »

    As an optimization, follow-up SRST used to be skipped if
    classification wasn't requested even when hardreset requested it via
    -EAGAIN. However, some hardresets can't wait for device readiness and
    skipping SRST can cause timeout or other failures during revalidation.
    Always perform follow-up SRST if hardreset returns -EAGAIN. This
    makes reset paths more predictable and thus less error-prone.

    While at it, move hardreset error checking such that it's done right
    after hardreset is finished. This simplifies followup SRST condition
    check a bit and makes the reset path easier to modify.

  • ebca4f1bc   PCI: fix reference leak in pci_get_dev_by_id() ... Browse Code »

    Alex Chiang and Matthew Wilcox pointed out that pci_get_dev_by_id() does
    not properly decrement the reference on the from pointer if it is
    present, like the documentation for the function states it will.

    It fixes a pretty bad leak in the hotplug core (we were leaking an
    entire struct pci_dev for each function of each offlined card, the first
    time around; subsequent onlines/offlines were ok).

    Commit ef0ff95f136f0f2d035667af5d18b824609de320 (shpchp: fix slot name)
    introduces the shpchp_slot_with_bus module parameter, which was intended
    to help work around broken firmware that assigns the same name to multiple
    slots.

    Commit b3bd307c628af2f0a581c42d5d7e4bcdbbf64b6a (shpchp: add message about
    shpchp_slot_with_bus option) tells the user to use the above parameter
    in the event of a name collision.

    This approach is sub-optimal because it requires too much work from
    the user.

    Instead, let's rename the slot on behalf of the user. If firmware
    assigns the name N to multiple slots, then:

    The first registered slot is assigned N
    The second registered slot is assigned N-1
    The third registered slot is assigned N-2
    The Mth registered slot becomes N-M

    In the event we overflow the slot->name parameter, we report an
    error to the user.

    This is a temporary fix until the entire PCI core can be reworked
    such that individual drivers no longer have to manage their own
    slot names.
