      pwm-backlight: switch to gpiod interface · 257462db
      Alexandre Courbot 提交于
      Switch to the new gpiod interface, which allows to handle GPIO
      properties such as active low transparently and removes a whole bunch of
      code.
      
      There are still a couple of users of this driver that rely on passing
      the enable GPIO number through platform data, so a fallback mechanism
      using a GPIO number is still available to avoid breaking them. It will
      be removed once current users have switched to the GPIO lookup tables
      provided by the gpiod interface.

      ARM: SAMSUNG: remove GPIO flags in dev-backlight · a4406f16
      Alexandre Courbot 提交于
      The pwm-backlight driver is moving to use the gpiod interface,
      which has its own mapping mechanism for platform data GPIOs.
      These mappings carry GPIO properties like active low so they don't have
      to be explicitly handled by GPIO consumers.
      
      Because of this change, the enable_gpio_flags member of
      platform_pwm_backlight_data is going away. dev-backlight was passing
      this member, but had no user making use of it, so it can safely be
      removed. Further GPIOs used by pwm-backlight are expected to be
      defined using the mechanisms provided by the gpiod API.

      sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue · fd1232b2
      Mikulas Patocka 提交于
      This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
      returns QUEUE FULL status.
      
      When the controller encounters an error (including QUEUE FULL or BUSY
      status), it aborts all not yet submitted requests in the function
      sym_dequeue_from_squeue.
      
      This function aborts them with DID_SOFT_ERROR.
      
      If the disk has full tag queue, the request that caused the overflow is
      aborted with QUEUE FULL status (and the scsi midlayer properly retries
      it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
      the following requests with DID_SOFT_ERROR --- for them, the midlayer
      does just a few retries and then signals the error up to sd.
      
      The result is that disk returning QUEUE FULL causes request failures.
      
      The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
      (rebranded ST336607LC) with command queue 48 or 64 tags.  The disk has
      64 tags, but under some access patterns it return QUEUE FULL when there
      are less than 64 pending tags.  The SCSI specification allows returning
      QUEUE FULL anytime and it is up to the host to retry.

      powerpc: Don't try to set LPCR unless we're in hypervisor mode · 18aa0da3
      Paul Mackerras 提交于
      Commit 8f619b54 ("powerpc/ppc64: Do not turn AIL (reloc-on
      interrupts) too early") added code to set the AIL bit in the LPCR
      without checking whether the kernel is running in hypervisor mode.  The
      result is that when the kernel is running as a guest (i.e., under
      PowerKVM or PowerVM), the processor takes a privileged instruction
      interrupt at that point, causing a panic.  The visible result is that
      the kernel hangs after printing "returning from prom_init".
      
      This fixes it by checking for hypervisor mode being available before
      setting LPCR.  If we are not in hypervisor mode, we enable relocation-on
      interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

      Commits 11d4616b ("futex: revert back to the explicit waiter
      counting code") and 69cd9eba ("futex: avoid race between requeue and
      wake") changed some of the finer details of how we think about futexes.
      One was a late fix and the other a consequence of overlooking the whole
      requeuing logic.
      
      The first change caused our documentation to be incorrect, and the
      second made us aware that we need to explicitly add more details to it.

      Pull yet more networking updates from David Miller:
      
       1) Various fixes to the new Redpine Signals wireless driver, from
          Fariya Fatima.
      
       2) L2TP PPP connect code takes PMTU from the wrong socket, fix from
          Dmitry Petukhov.
      
       3) UFO and TSO packets differ in whether they include the protocol
          header in gso_size, account for that in skb_gso_transport_seglen().
         From Florian Westphal.
      
       4) If VLAN untagging fails, we double free the SKB in the bridging
          output path.  From Toshiaki Makita.
      
       5) Several call sites of sk->sk_data_ready() were referencing an SKB
          just added to the socket receive queue in order to calculate the
          second argument via skb->len.  This is dangerous because the moment
          the skb is added to the receive queue it can be consumed in another
          context and freed up.
      
          It turns out also that none of the sk->sk_data_ready()
          implementations even care about this second argument.
      
          So just kill it off and thus fix all these use-after-free bugs as a
          side effect.
      
       6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti.
      
       7) pktgen needs to do locking properly for LLTX devices, from Daniel
          Borkmann.

          Vincenzo Maffione.
      
       9) After refactoring, some tunnel drivers allow a tunnel to be
          configured on top itself.  Fix from Nicolas Dichtel.
