  • This removes the use of the special "macbookair_fn_keys" keyboard
    translation table for the MacBookAir4,x models (ie the 2011 refresh).
    They use the standard apple_fn_keys[] translation. Apparently only the
    old MacBook Air's need a different translation table.

    This mirrors the change that commit da617c7cb915 ("HID: consolidate
    MacbookAir 4,1 mappings") did for the WELLSPRING6A ones, but does it for
    the WELLSPRING6 model used on the MacBookAir4,2.

  • The definition of TO_ATTR_NO in the non-SMP case is wrong. As the SMP
    definition resolves to the correct value, just use this for both
    cases.

    Without this fix the temperature attributes are named temp0_* instead
    of temp2_*, so libsensors won't pick them. Broken since kernel 3.0.

  • The includes in the pxa2xx_cm_x2xx PCMCIA driver are rather random;
    the driver doesn't require anything from these headers except the
    cpu_is_xxx() macros which come from another include.

    The concern is that it's getting these definitions via mach/system.h,
    which is supposed to only be included by arch/arm/kernel/process.c.
    As this header is scheduled for cleanup (and elimination) keeping
    the status quo will cause build errors. So lets fix properly and
    independent of the future work.

  • Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver
    Jiri Slaby: 28d41f53f broke temperature sensors on a ICH10 chipset

    The iTCO_wdt driver disables the SMI. This breaks good working of newer hardware.
    The disabling of the SMI by the TCO logic dates back from the i810-tco driver
    from Nils Faerber (around 28 July 2000). The reason for this was that some BIOSes
    install handlers reset or disable the watchdog timer instead of resetting the system.
    The trick to fix this was to disable the SMI (by clearing the SMI_TCO_EN bit of the
    SMI_EN register) to prevent this from happening.

    This however has strange effects on newer hardware. So we are in a situation that
    a fix for broken old hardware affects newer hardware.

    The correct solution is to make this fix an option (with the new module parameter:
    turn_SMI_watchdog_clear_off) so that the default behaviour is the unfixed version.

    the next patch will be to move this in the start and stop functions of the driver
    and to add a new module parameter for the global_smi_en bit and to get rid of the
    vendor_support code.

    This fix can have an effect on old (typical ICH & ICH2 chipsets) motherboards that
    have a broken BIOS implementation concerning TCO logic. In these case the module
    parameter turn_SMI_watchdog_clear_off=1 will need to be added.

  • This is to exclude it from force threading to allow RT patch set to work.

    The watchdog timers are per-CPU and the addresses of register that reset
    the timer are calculated based on the current CPU. Therefore we cannot
    allow it to run on a thread on a different CPU. Also we only do a
    single register write, which is much faster than scheduling a handler
    thread.

    And while on this line remove IRQF_DISABLED as this flag is a NOP.

  • Originally, the runtime PM core would send an idle notification
    whenever a suspend attempt failed. The idle callback routine could
    then schedule a delayed suspend for some time later.

    However this behavior was changed by commit
    f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle
    notification after failing suspend). No notifications were sent, and
    there was no clear mechanism to retry failed suspends.

    This caused problems for the usbhid driver, because it fails
    autosuspend attempts as long as a key is being held down. A companion
    patch changes the PM core's behavior, but we also need to change the
    USB core. In particular, this patch (as1493) updates the device's
    last_busy time when an autosuspend fails, so that the PM core will
    retry the autosuspend in the future when the delay time expires
    again.

    The RC error state flush logic in qib_make_rc_req() could return all
    of the acked wqes and potentially have emptied the queue. It would
    then unconditionally try return a flush completion via
    qib_send_complete() for an invalid wqe, or worse a valid one that is
    not queued. The panic results when the completion code tries to
    maintain an MR reference count for a NULL MR.

    This fix modifies logic to only send one completion per
    qib_make_rc_req() call and changing the completion status from
    IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress.

    The outer loop will call as many times as necessary to flush the queue.

  • The current driver never does DMA unmapping on these buffers. Fix that
    by adding DMA unmapping to the task cleanup callback, and DMA mapping to
    the task init function (drop the headers_initialized micro-optimization).

  • The driver counted on the transactional nature of iSCSI login/text
    flows and used the same buffer for both the request and the response.
    We also went further and did DMA mapping only once, with
    DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by
    using different buffers, one for requests and one for responses, and
    use the correct DMA mapping direction for each.
