      IB/cma: Fix broken AF_IB UD support · c07678bb
      Matthew Finlay authored
      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 · c29ed5a4
      Ted Kim authored
      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 · c447e76b
      Liang Li authored
      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.

      HID: wacom: fix an Oops caused by wacom_wac_finger_count_touches · 26ba61f8
      Ping Cheng authored
      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 · 219f47e4
      Takashi Iwai 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 · 48f4b3a2
      Takashi Iwai 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
      [d545a57c: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.

      ALSA: sound/atmel/ac97c.c: remove unused variable · 976fa9a3
      Arnd Bergmann authored
      The recently added DT support for the ac97 driver is causing
      a gcc warning:
      
      sound/atmel/ac97c.c: In function 'atmel_ac97c_probe_dt':
      sound/atmel/ac97c.c:919:29: warning: unused variable 'match' [-Wunused-variable]
        const struct of_device_id *match;
      
      The variable is clearly unused, so we can remove it.
