      Input: smtpe-ts - wait 50mS until polling for pen-up · 77b071e7
      Marek Vasut authored
      Wait a little bit longer, 50mS instead of 20mS, until the driver starts
      polling for pen-up. The problematic behavior before this patch is applied
      is as follows. The behavior was observed on the STMPE610QTR controller.
      
      Upon a physical pen-down event, the touchscreen reports one set of x-y-p
      coordinates and a pen-down event. After that, the pen-up polling is
      triggered and since the controller is not ready yet, the polling mistakenly
      detects a pen-up event while the physical state is still such that the pen
      is down on the touch surface.
      
      The pen-up handling flushes the controller FIFO, so after that, all the
      samples in the controller are discarded. The controller becomes ready
      shortly after this bogus pen-up handling and does generate again a pen-down
      interrupt. This time, the controller contains x-y-p samples which all read
      as zero. Since pressure value is zero, this set of samples is effectively
      ignored by userland.
      
      In the end, the driver just bounces between pen-down and bogus pen-up
      handling, generating no useful results. Fix this by giving the controller a
      bit more time before polling it for pen-up.

      md/bitmap: remove rcu annotation from pointer arithmetic. · 8532e343
      NeilBrown authored
      Evaluating  "&mddev->disks" is simple pointer arithmetic, so
      it does not need 'rcu' annotations - no dereferencing is happening.
      
      Also enhance the comment to explain that 'rdev' in that case
      is not actually a pointer to an rdev.

      md/raid0: fix restore to sector variable in raid0_make_request · a8115776
      Eric Work authored
      The variable "sector" in "raid0_make_request()" was improperly updated
      by a call to "sector_div()" which modifies its first argument in place.
      Commit 47d68979 restored this variable
      after the call for later re-use.  Unfortunetly the restore was done after
      the referenced variable "bio" was advanced.  This lead to the original
      value and the restored value being different.  Here we move this line to
      the proper place.
      
      One observed side effect of this bug was discarding a file though
      unlinking would cause an unrelated file's contents to be discarded.

      Input: alps - fix finger jumps on lifting 2 fingers on v7 touchpad · 72eceab7
      Hans de Goede authored
      On v7 touchpads sometimes when 2 fingers are moved down on the touchpad
      until they "fall of" the touchpad, the second touch will report 0 for y
      (max y really since the y axis is inverted) and max x as coordinates,
      rather then reporting 0, 0 as is expected for a non touching finger.
      
      This commit detects this and treats these touches as non touching.

      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.

      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.

      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.

      The variable is clearly unused, so we can remove it.
