    IB/cma: Fix broken AF_IB UD support

    Matthew Finlay authored dledford committed
    Support for using UD and AF_IB is currently broken.  The
    IB_CM_SIDR_REQ_RECEIVED message is not handled properly in
    cma_save_net_info() and we end up falling into code that will try and
    process the request as ipv4/ipv6, which will end up failing.
    
    The resolution is to add a check for the SIDR_REQ and call
    cma_save_ib_info() with a NULL path record.  Change cma_save_ib_info()
    to copy the src sib info from the listen_id when the path record is NULL.

    ib/cm: Change reject message type when destroying cm_id

    Ted Kim authored dledford committed
    Problem reported by: Ted Kim <ted.h.kim@oracle.com>:
    
    We have a case where a Linux system and a non-Linux system are
    trying to interoperate.  The Linux host is the active side and
    starts the connection establishment, but later decides to not go
    through with the connection setup and does rdma_destroy_id().
    
    The rdma_destroy_id() eventually works its way down to cm_destroy_id()
    in core/cm.c, where a REJ is sent. The non-Linux system
    has some trouble recognizing the REJ because of:
    
    A. CM states which can't receive the REJ
    B. Some issues about REJ formatting (missing comm ID)
    
    ISSUE A: That part of the spec says, a Consumer Reject REJ can be
    sent for a connection abort, but it goes further
    and says: can send a REJ message with a "Consumer Reject"
    Reason code if they are in a CM state (i.e. REP
    Rcvd, MRA(REP) Sent, REQ Rcvd, MRA Sent) that allows
    a REJ to be sent (lines 35-38).
    
    Of the states listed there in that sentence, it would
    seem to limit the active side to using the Consumer Reject
    (for the abort case) in just the REP-Rcvd and MRA-REP-Sent
    states. That is basically only after the active side
    sees a REP (or alternatively goes down the state transitions
    to timeout in which case a Timeout REJ is sent).
    
    As a fix, in cm-destroy-id() move the IB-CM-MRA-REQ-RCVD case
    to the same as REQ-SENT.  Essentially, make a REJ sent after
    getting an MRA on active side a timeout rather than Consumer-
    Reject, which is arguably more correct with the CM state
    diagrams previous to getting a REP.

    kvm/fpu: Enable eager restore kvm FPU for MPX

    Liang Li authored bonzini committed
    The MPX feature requires eager KVM FPU restore support. We have verified
    that MPX cannot work correctly with the current lazy KVM FPU restore
    mechanism. Eager KVM FPU restore should be enabled if the MPX feature is
    exposed to VM.

    We assumed all touch interfaces report touch data. But, Bamboo
    and Intuos non-touch devices report express keys on touch
    interface. We need to check touch_max before counting touches.

    ALSA: hda - Disable widget power-saving for ALC292 & co

    tiwai authored
    We've got reports that ALC3226 (a Dell variant of ALC292) gives click
    noises at transition from D3 to D0 when the widget power-saving is
    enabled.  Further debugging session showed that avoiding it isn't
    trivial, unfortunately, since paths are basically activated
    dynamically while the pins have been already enabled.
    
    This patch disables the widget power-saving for such codecs.

    ALSA: hda - Reduce verbs by node power-saves

    tiwai authored
    The widget (node) power-saves restore the widget states at each
    transition from D3 to D0 on each node.  This was added in the commit
    [d545a57:ALSA: hda - Sync node attributes at resume from widget
    power saving].  However, the test was rater false-positive; this
    wasn't needed for any codecs.
    
    Since the resync may take significant number of additional verbs to be
    executed, it's better to reduce it.  Let's disable it for now again.

    The recently added DT support for the ac97 driver is causing

      const struct of_device_id *match;
    
    The variable is clearly unused, so we can remove it.

    xen/events: don't bind non-percpu VIRQs with percpu chip

    dvrabel authored
    A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different
    VCPU than it is bound to.  This can result in a race between
    handle_percpu_irq() and removing the action in __free_irq() because
    handle_percpu_irq() does not take desc->lock.  The interrupt handler
    sees a NULL action and oopses.
    
    Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER).

    pwm: img: Impose upper and lower timebase steps value

    Naidu Tellapati authored thierryreding committed
    The PWM hardware on Pistachio platform has a maximum timebase steps
    value to 255. To fix it, let's introduce a compatible-specific
    data structure to contain the SoC-specific details and use it to
    specify a maximum timebase.
    
    Also, let's limit the minimum timebase to 16 steps, to allow a sane
    range of duty cycle steps.

    ALSA: pcm: Modify double acknowledged interrupts check condition

    korochen authored tiwai committed
    Currently in snd_pcm_update_hw_ptr0 during interrupt,
    we consider there were double acknowledged interrupts when:
    1. HW reported pointer is smaller than expected, and
    2. Time from last update time (hdelta) is over half a buffer time.
    
    However, when HW reported pointer is only a few bytes smaller than
    expected, and when hdelta is just a little larger than half a buffer time
    (e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged.
    
    The condition #2 uses jiffies, but jiffies is not high resolution
    since it is integer. We should consider jiffies inaccuracy.

  2. watchdog: Fix merge 'conflict'

    Peter Zijlstra authored committed
    Two watchdog changes that came through different trees had a non
    conflicting conflict, that is, one changed the semantics of a variable
    but no actual code conflict happened. So the merge appeared fine, but
    the resulting code did not behave as expected.
    
    Commit 195daf6 ("watchdog: enable the new user interface of the
    watchdog mechanism") changes the semantics of watchdog_user_enabled,
    which thereafter is only used by the functions introduced by
    b3738d2 ("watchdog: Add watchdog enable/disable all functions").
    
    There further appears to be a distinct lack of serialization between
    setting and using watchdog_enabled, so perhaps we should wrap the
    {en,dis}able_all() things in watchdog_proc_mutex.
    
    This patch fixes a s2r failure reported by Michal; which I cannot
    readily explain. But this does make the code internally consistent
    again.
