 "Round three of 4.8 rc fixes.

  This is likely the last rdma pull request this cycle.  The new rxe
  driver had a few issues (you probably saw the boot bot bug report) and
  they should be addressed now.  There are a couple other fixes here,
  mainly mlx4.  There are still two outstanding issues that need
  resolved but I don't think their fix will make this kernel cycle.

  Summary:

   - Various fixes to rdmavt, ipoib, mlx5, mlx4, rxe"

      Pull ARM SoC fixes from Arnd Bergmann:
 "Here are a couple of bugfixes for v4.8-rc.

  Most of them have actually been around for a while this time but for
  some reason didn't get applied early on.  The shmobile regulator fix
  is the only one that isn't completely obvious.

  Device tree changes:
   - archtimer interrupts must be level triggered (multiple platforms)
   - fix for USB and MMC clocks on STiH410
   - fix split DT repository in case of raspberry-pi 3
   - a new use of skeleton.dtsi on arm64 has crept in after that was
     removed.

  defconfig updates:
   - xilinx vdma has a new Kconfig symbol name
   - keystone requires CONFIG_NOP_USB_XCEIV since v4.8-rc1

  Code fixes:
   - fix regulator quirk on shmobile
   - suspend-to-ram regression on EXYNOS

  Maintainer updates:
   - Javier Martinez Canillas is now a reviewer for Samsung EXYNOS"

      Linus Torvalds authored 
      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"

      The userspace memory region 'mr' is allocated with kzalloc in
__rvt_alloc_mr  however it is incorrectly being freed with vfree in
__rvt_free_mr. Fix this by using kfree to free it.

      IB/rxe: Fix race condition between requester and completer · 3050b998
      Yonatan Cohen authored 
      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 authored 
      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()
