Pull nfsd updates from Bruce Fields:
 "Olga added support for the NFSv4.2 asynchronous copy protocol. We
  already supported COPY, by copying a limited amount of data and then
  returning a short result, letting the client resend. The asynchronous
  protocol should offer better performance at the expense of some
  complexity.

  The other highlight is Trond's work to convert the duplicate reply
  cache to a red-black tree, and to move it and some other server caches
  to RCU. (Previously these have meant taking global spinlocks on every
  RPC)

Pull tracing updates from Steven Rostedt:
 "The biggest change here is the updates to kprobes

  Back in January I posted patches to create function based events.
  These were the events that you suggested I make to allow developers to
  easily create events in code where no trace event exists. After
  posting those changes for review, it was suggested that we implement
  this instead with kprobes.

  The problem with kprobes is that the interface is too complex and
  needs to be simplified. Masami Hiramatsu posted patches in March and
  I've been playing with them a bit. There's been a bit of clean up in
  the kprobe code that was inspired by the function based event patches,
  and a couple of enhancements to the kprobe event interface.

   - If the arch supports it (we added support for x86), you can place a
     kprobe event at the start of a function and use $arg1, $arg2, etc
     to reference the arguments of a function. (Before you needed to
     know what register or where on the stack the argument was).

   - The second is a way to see array of events. For example, if you
     reference a mac address, you can add:

	echo 'p:mac ip_rcv perm_addr=+574($arg2):x8[6]' > kprobe_events

     And this will produce:

	mac: (ip_rcv+0x0/0x140) perm_addr={0x52,0x54,0x0,0xc0,0x76,0xec}

  Other changes include

   - Exporting trace_dump_stack to modules

   - Have the stack tracer trace the entire stack (stop trying to remove
     tracing itself, as we keep removing too much).

   - Added support for SDT in uprobes"

   - The TEE subsystem gains an in-kernel interface to access the TEE
     from device drivers.

   - The reset controller subsystem gains a driver for the Qualcomm
     Snapdragon 845 Power Domain Controller.

   - The Xilinx Zynq platform now has a firmware interface for its
     platform management unit. This contains a firmware "ioctl"
     interface that was a little controversial at first, but the version
     we merged solved that by not exposing arbitrary firmware calls to
     user space.

   - The Amlogic Meson platform gains a "canvas" driver that is used for
     video processing and shared between different high-level drivers.

  The rest is more of the usual, mostly related to SoC specific power
  management support and core drivers in drivers/soc:

   - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
     features related to power and reset control.

   - The Mediatek mt8183 and mt6765 SoC platforms gain support for their

Pull ARM SoC device tree updates from Arnd Bergmann:
 "There are close to 800 indivudal changesets in this branch again,
  which feels like a lot. There are particularly many changes for the
  NVIDIA Tegra platform this time, in fact more than it has seen in the
  two years since the v4.9 merge window. Aside from this, it's been
  fairly normal, with lots of changes going into Renesas R-CAR, NXP
  i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP.

  Most of the changes are for adding new features into existing boards,
  for brevity I'm only mentioning completely new machines and SoCs here.
  For the first time I think we have (slightly) more new 64-bit hardware
  than 32-bit:

  Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
  computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a
  minor variation of the motherboards of the GTA04 phone, see
  https://shop.goldelico.com/wiki.php?page=GTA04A5

  Clearfog is a nice little board for quad-core Marvell Armada 8040
  network processor, see
  https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/

  Two additional server boards come with the Aspeed baseboard management
  controllers: Stardragon4800 is an arm64 reference platform made by HXT
  (based on Qualcomm's server chips), and TiogaPass is an Open Compute
  mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the
  BMC.

  NXP i.MX usually sees a lot of new boards each release. This time
  there we only add one minor variant: ConnectCore 6UL SBC Pro uses the
  same SoM design as the ConnectCore 6UL SBC Express added later.
  However, there is a new chip, the i.MX6ULZ, which is an even smaller
  variant of the i.MX6ULL, with features removed. There is also support
  for the reference board design, the i.MX6ULZ 14x14 EVK.

  A new Raspberry Pi variant gets added, this one is the CM3 compute
  module based on bcm2837, it was launched in early 2017 but only now
  added to the kernel, both as 32-bit and as 64-bit files, as we tend to
  do for Raspberry Pi.

  On the Allwinner side, everything is again about cheap development
  boards, usually of the "Fruit Pi" variety. The new ones this time are:
   - Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
   - Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
   - Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
   - Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
  The last one of these is now a 64-bit version of the earlier Banana Pi
  M2+ H3, with the same board layout.

  Similarly, for Rockchips, get get another variant of the 32-bit Asus
  Tinker board, the model 'S' based on rk3288, and three now boards
  based on the popular RK3399 chip:
   - ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
   - Rock960: https://www.96boards.org/product/rock960/
   - RockPro64: https://www.pine64.org/?page_id=61454
  These are all quite powerful boards with lots of RAM and I/O, and the
  RK3399 is the same chip used in several Chromebooks. Finally, we get
  support for the PX30 (aka rk3326) chip, which is based on the low-end
  64-bit Cortex-A35 CPU core. So far, only the evaluation board is
  supported.

  One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is
  based on the MT7622 WiFi router platform, and the first product I've
  seen with a 64-bit Mediatek chip in that market:
  http://www.banana-pi.org/r64.html

  For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
  development board, which are similar to the Hi3660 and Hikey 360
  respectively, but add support for an NPU.

  Amlogic gets initial support for the Meson-G12A chip (S905D2), another
  quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit
  side, we gain support for an actual end-user product, the Endless
  Computers Endless Mini based on Meson8b (S805), see
  https://endlessos.com/computers/

  Qualcomm adds support for their MSM8998 SoC and evaluation platform.
  This chip is commonly known as the Snapdragon 835, and is used in
  high-end phones as well as low-end laptops.

  For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
  but no boards for this one. However, we do add boards for the
  previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the
  M3NULCB Starter Kit Pro.

  While we have lots of DT changes for NVIDIA to update the existing
  files, the only board that gets added is the Toradex Colibri T20 on
  Colibri Evaluation Board for the old Tegra2.

In call_xpt_users(), we delete the entry from the list, but we
do not reinitialise it. This triggers the list poisoning when
we later call unregister_xpt_user() in nfsd4_del_conns().

alloc_init_deleg() both allocates an nfs4_delegation, and
bumps the refcount on odstate. So after this point, we need to
put_clnt_odstate() and nfs4_put_stid() to not leave the odstate
refcount inappropriately bumped.

Reduce queuing on clients by allowing more credits by default.

64 is the default NFSv4.1 slot table size on Linux clients. This
size prevents the credit limit from putting RPC requests to sleep
again after they have already slept waiting for a session slot.

Since commit ffe1f0df ("rpcrdma: Merge svcrdma and xprtrdma

Similar to a change made in the client's forward channel reply
handler: The xprt_release_rqst_cong() call is not necessary.

Also, release xprt->recv_lock when taking xprt->transport_lock

Simplify the duplicate replay cache by initialising the preallocated
cache entry, so that we can use it as a key for the cache lookup.

Note that the 99.999% case we want to optimise for is still the one
where the lookup fails, and we have to add this entry to the cache,
so preinitialising should not cause a performance penalty.
