      Pull ARM fixes from Russell King:
       "Most of this update are fixes primarily discovered from testing on the
        older StrongARM 1110 and PXA systems, as a result of recent interest
        from several people in these platforms:
      
         - Locomo interrupt handling incorrectly stores the handler data in
           the chip's private data slot: when Locomo is combined with an
           interrupt controller who's chip uses the chip private data, this
           leads to an oops.
      
         - SA1111 was missing a call to clk_disable() to clean up after a
           failed probe.
      
         - SA1111 and PCMCIA suspend/resume was broken:
      
           The PCMCIA "ds" layer was using the legacy bus suspend/resume
           methods, which the core PM code is no longer calling as a result of
           device_pm_check_callbacks() introduced in commit aa8e54b5
           ("PM / sleep: Go direct_complete if driver has no callbacks").
      
           SA1111 was broken due to changes to PCMCIA which makes PCMCIA
           suspend itself later than the SA1111 code expects, and resume
           before the SA1111 code has initialised access to the pcmcia
           sub-device.
      
         - the default SA1111 interrupt mask polarity got messed up when it
           was converted to use a dynamic interrupt base number for its
           interrupts.
      
         - fix platform_get_irq() error code propagation, which was causing
           problems on platforms where the interrupt may not be available at
            probe time in DT setups.
      
         - fix the lack of clock to PCMCIA code on PXA platforms, which was
           omitted in conversions of PXA to CCF.
      
         - fix an oops in the PXA PCMCIA code caused by a previous commit not
           realising that Lubbock is different from the rest of the PXA PCMCIA
           drivers.
      
         - ensure that SA1111 low-level PCMCIA drivers propagate their error
           codes to the main probe function, rather than the driver silently
           accepting a failure.
      
         - fix the sa11xx debugfs reporting of timing information, which
           always indicated zero due to the clock being a factor of 1000 out.
      
         - fix the polarity of the status change signal reported from the
           sockets.
      
        Lastly, one ARM specific commit from Stefan Agner fixing the LPAE
        cache attributes"

      IB/rxe: Fix race condition between requester and completer · 3050b998
      Yonatan Cohen 提交于
      rxe_requester() is sending a pkt with rxe_xmit_packet() and
      then calls rxe_update() to update the wqe and qp's psn values.
      But sometimes the response is received before the requester
      had time to update the wqe in which case the completer
      acts on errornous wqe values.
      This fix updates the wqe and qp before actually sending
      the request and rolls back when xmit fails.

      IB/rxe: Fix duplicate atomic request handling · 90894887
      Yonatan Cohen 提交于
      When handling ack for atomic opcodes like "fetch&add"
      or "cmp&swp", the method send_atomic_ack() saves the ack
      before sending it, in case it gets lost and never reach the
      requester. In which case the method duplicate_request()
      will need to find it using the duplicated request.psn.
      But send_atomic_ack() used a wrong psn value and thus
      the above ack was never found.
      This fix uses the ack.psn to locate the ack in case
      its needed.
      This fix also copies the ack packet to the skb's control buffer
      since duplicate_request() will need it when calling rxe_xmit_packet()

      IB/mlx4: Use correct subnet-prefix in QP1 mads under SR-IOV · 8ec07bf8
      Jack Morgenstein 提交于
      When sending QP1 MAD packets which use a GRH, the source GID
      (which consists of the 64-bit subnet prefix, and the 64 bit port GUID)
      must be included in the packet GRH.
      
      For SR-IOV, a GID cache is used, since the source GID needs to be the
      slave's source GID, and not the Hypervisor's GID. This cache also
      included a subnet_prefix. Unfortunately, the subnet_prefix field in
      the cache was never initialized (to the default subnet prefix 0xfe80::0).
      As a result, this field remained all zeroes.  Therefore, when SR-IOV
      was active, all QP1 packets which included a GRH had a source GID
      subnet prefix of all-zeroes.
      
      However, the subnet-prefix should initially be 0xfe80::0 (the default
      subnet prefix). In addition, if OpenSM modifies a port's subnet prefix,
      the new subnet prefix must be used in the GRH when sending QP1 packets.
      To fix this we now initialize the subnet prefix in the SR-IOV GID cache
      to the default subnet prefix. We update the cached value if/when OpenSM
      modifies the port's subnet prefix. We take this cached value when sending
      QP1 packets when SR-IOV is active.
      
      Note that the value is stored as an atomic64. This eliminates any need
      for locking when the subnet prefix is being updated.
      
      Note also that we depend on the FW generating the "port management change"
      event for tracking subnet-prefix changes performed by OpenSM. If running
      early FW (before 2.9.4630), subnet prefix changes will not be tracked (but
      the default subnet prefix still will be stored in the cache; therefore
      users who do not modify the subnet prefix will not have a problem).
      IF there is a need for such tracking also for early FW, we will add that
      capability in a subsequent patch.

      The indentation in the QP1 GRH flow in procedure build_mlx_header is
      really confusing. Fix it, in preparation for a commit which touches
      this code.

      IB/mlx4: Fix incorrect MC join state bit-masking on SR-IOV · e5ac40cd
      Alex Vesker 提交于
      Because of an incorrect bit-masking done on the join state bits, when
      handling a join request we failed to detect a difference between the
      group join state and the request join state when joining as send only
      full member (0x8). This caused the MC join request not to be sent.
      This issue is relevant only when SRIOV is enabled and SM supports
      send only full member.
      
      This fix separates scope bits and join states bits a nibble each.

      IB/ipoib: Don't allow MC joins during light MC flush · 344bacca
      Alex Vesker 提交于
      This fix solves a race between light flush and on the fly joins.
      Light flush doesn't set the device to down and unset IPOIB_OPER_UP
      flag, this means that if while flushing we have a MC join in progress
      and the QP was attached to BC MGID we can have a mismatches when
      re-attaching a QP to the BC MGID.
      
      The light flush would set the broadcast group to NULL causing an on
      the fly join to rejoin and reattach to the BC MCG as well as adding
      the BC MGID to the multicast list. The flush process would later on
      remove the BC MGID and detach it from the QP. On the next flush
      the BC MGID is present in the multicast list but not found when trying
      to detach it because of the previous double attach and single detach.
