9ff9b0d392 networking changes for the 5.10 merge window 
Add redirect_neigh() BPF packet redirect helper, allowing to limit stack
 traversal in common container configs and improving TCP back-pressure.
 Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.
 
 Expand netlink policy support and improve policy export to user space.
 (Ge)netlink core performs request validation according to declared
 policies. Expand the expressiveness of those policies (min/max length
 and bitmasks). Allow dumping policies for particular commands.
 This is used for feature discovery by user space (instead of kernel
 version parsing or trial and error).
 
 Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge.
 
 Allow more than 255 IPv4 multicast interfaces.
 
 Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
 packets of TCPv6.
 
 In Multi-patch TCP (MPTCP) support concurrent transmission of data
 on multiple subflows in a load balancing scenario. Enhance advertising
 addresses via the RM_ADDR/ADD_ADDR options.
 
 Support SMC-Dv2 version of SMC, which enables multi-subnet deployments.
 
 Allow more calls to same peer in RxRPC.
 
 Support two new Controller Area Network (CAN) protocols -
 CAN-FD and ISO 15765-2:2016.
 
 Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
 kernel problem.
 
 Add TC actions for implementing MPLS L2 VPNs.
 
 Improve nexthop code - e.g. handle various corner cases when nexthop
 objects are removed from groups better, skip unnecessary notifications
 and make it easier to offload nexthops into HW by converting
 to a blocking notifier.
 
 Support adding and consuming TCP header options by BPF programs,
 opening the doors for easy experimental and deployment-specific
 TCP option use.
 
 Reorganize TCP congestion control (CC) initialization to simplify life
 of TCP CC implemented in BPF.
 
 Add support for shipping BPF programs with the kernel and loading them
 early on boot via the User Mode Driver mechanism, hence reusing all the
 user space infra we have.
 
 Support sleepable BPF programs, initially targeting LSM and tracing.
 
 Add bpf_d_path() helper for returning full path for given 'struct path'.
 
 Make bpf_tail_call compatible with bpf-to-bpf calls.
 
 Allow BPF programs to call map_update_elem on sockmaps.
 
 Add BPF Type Format (BTF) support for type and enum discovery, as
 well as support for using BTF within the kernel itself (current use
 is for pretty printing structures).
 
 Support listing and getting information about bpf_links via the bpf
 syscall.
 
 Enhance kernel interfaces around NIC firmware update. Allow specifying
 overwrite mask to control if settings etc. are reset during update;
 report expected max time operation may take to users; support firmware
 activation without machine reboot incl. limits of how much impact
 reset may have (e.g. dropping link or not).
 
 Extend ethtool configuration interface to report IEEE-standard
 counters, to limit the need for per-vendor logic in user space.
 
 Adopt or extend devlink use for debug, monitoring, fw update
 in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw,
 mv88e6xxx, dpaa2-eth).
 
 In mlxsw expose critical and emergency SFP module temperature alarms.
 Refactor port buffer handling to make the defaults more suitable and
 support setting these values explicitly via the DCBNL interface.
 
 Add XDP support for Intel's igb driver.
 
 Support offloading TC flower classification and filtering rules to
 mscc_ocelot switches.
 
 Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
 fixed interval period pulse generator and one-step timestamping in
 dpaa-eth.
 
 Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
 offload.
 
 Add Lynx PHY/PCS MDIO module, and convert various drivers which have
 this HW to use it. Convert mvpp2 to split PCS.
 
 Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
 7-port Mediatek MT7531 IP.
 
 Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
 and wcn3680 support in wcn36xx.
 
 Improve performance for packets which don't require much offloads
 on recent Mellanox NICs by 20% by making multiple packets share
 a descriptor entry.
 
 Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto
 subtree to drivers/net. Move MDIO drivers out of the phy directory.
 
 Clean up a lot of W=1 warnings, reportedly the actively developed
 subsections of networking drivers should now build W=1 warning free.
 
 Make sure drivers don't use in_interrupt() to dynamically adapt their
 code. Convert tasklets to use new tasklet_setup API (sadly this
 conversion is not yet complete).

Pull drm updates from Dave Airlie:
 "Not a major amount of change, the i915 trees got split into display
  and gt trees to better facilitate higher level review, and there's a
  major refactoring of i915 GEM locking to use more core kernel concepts
  (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards
  get DC support, nouveau got a bump in displayport support with common
  code extraction from i915.

  Outside of drm this contains a couple of patches for hexint
  moduleparams which you've acked, and a virtio common code tree that
  you should also get via it's regular path.

efc7d01a9e docs: net: 80211: reduce docs build time 
the files under /80211 calls kernel-doc script 207 times, one for each
single function and doc chapter. Due to that, it takes a lot of time
handling it:

	$ touch Documentation/driver-api/80211/*rst && time make SPHINXDIRS=driver-api/80211 htmldocs
...
	real	0m22,928s
	user	0m21,644s
	sys	0m1,334s

Reduce the build time by doing only one kernel-doc call
per functions that belong to the same group. With that, there's now
50 calls to kernel-doc, which makes the build time for those docs
62% faster:

	$ touch Documentation/driver-api/80211/*rst && time make SPHINXDIRS=driver-api/80211 htmldocs
...
	real	0m8,666s
	user	0m8,084s
	sys	0m0,642s

As a side effect, it should now be easier to add newer
functions, as there's no need to repeat the kernel-doc
pattern.

Measurements made on a NUC8i7HNK machine with lots of ram
and a fast SSD disk with Sphinx 3.2.1.

c3cfc5f484 media: cec-core.rst: fix warnings with Sphinx 3.0+ 
The new C domain code on Sphinx 3 is a lot more pedantic.
It only accepts real functions declared as c:function.

So, declarations like this are not valid:

	.. c:function::
	        int (*adap_enable)(struct cec_adapter *adap, bool enable);

Also, no blank lines are allowed after ".. c:function:", and
continuation lines should be like:

	.. c:function:
		int (void foo, \
		     int bar);

Change the logic there, in order to avoid lots of warnings
when built with Sphinx 3.x.

The subdev registration topic is pretty lengthy, and takes more than
half of the "V4L2 sub-devices" section. Help readers in finding their
way through the document by dedicating a subsection to
"Subdev registration".

Each of the two registration methods takes many paragraphs, but since
adding a subsubsection would be overkill, just emphasize them in bold.

because the chapter name was wrong.

001e92922c docs: soundwire: fix some identation at stream.rst 
Currently, sphinx emits one warning on this file:

	Documentation/driver-api/soundwire/stream.rst:522: WARNING: Block quote ends without a blank line; unexpected unindent.

That's due to some extra spaces before the title of a chapter.

Yet, the list afterwards is missing identation.

So, address both issues.

implicitly like devm_kmemdup(), devm_kstrdup() etc.).

Managed realloc'ed chunks can be manually released with devm_kfree().

4c8e84b887 drm/managed: Cleanup of unused functions and polishing docs 
Following functions are only used internally, not by drivers:
- devm_drm_dev_init

Also, now that we have a very slick and polished way to allocate a
drm_device with devm_drm_dev_alloc, update all the docs to reflect the
new reality. Mostly this consists of deleting old and misleading
hints. Two main ones:

- it is no longer required that the drm_device base class is first in
  the structure. devm_drm_dev_alloc can cope with it being anywhere

- obviously embedded now strongly recommends using devm_drm_dev_alloc

v2: Fix typos (Noralf)

v3: Split out the removal of drm_dev_init, that's blocked on some
discussions on how to convert vgem/vkms/i915-selftests. Adjust commit
message to reflect that.

c0c419c045 Staging/IIO driver patches for 5.9-rc1 
Here is the large set of Staging and IIO driver patches for 5.9-rc1.
 
 Lots of churn here, but overall the size increase in lines added is
 small, while adding a load of new IIO drivers.
 
 Major things in here:
 	- lots and lots of IIO new drivers and frameworks added
 	- IIO driver fixes and updates
 	- lots of tiny coding style cleanups for staging drivers
 	- vc04_services major reworks and cleanups
 
 We had 3 set of drivers move out of staging in this round as well:
 	- wilc1000 wireless driver moved out of staging
 	- speakup moved out of staging
 	- most USB driver moved out of staging
 
 Full details are in the shortlog.
 
 All of these have been in linux-next with no reported issues.  The last
 few changes here were to resolve reported linux-next issues, and they
 seem to have resolved the problems.

1d8ce0e093 This is the bulk of GPIO changes for the v5.9 kernel cycle: 
Core changes:
 
 - Introduce the for_each_requested_gpio() macro to help in
   dependent code all over the place. Also patch a few locations
   to use it while we are at it.
 
 - Split out the sysfs code into its own file.
 
 - Split out the character device code into its own file, then
   make a set of refactorings and improvements to this code.
   We are setting the stage to revamp the userspace API a bit
   in the next cycle.
 
 - Fix a whole slew of kerneldoc that was wrong or missing.
 
 New drivers:
 
 - The PCA953x driver now supports the PCAL9535.
 
 Driver improvements:
 
 - A host of incremental modernizations and improvements to the
   PCA953x driver.
 
 - Incremental improvements to the Xilinx Zynq driver.
 
 - Some improvements to the GPIO aggregator driver.
 
 - I ran all over the place switching all threaded and other
   drivers requesting their own IRQ while using the core
   GPIO IRQ helpers to pass the GPIO irq chip as a template
   instead of calling the explicit set-up functions. Next merge
   window we may retire the old code altogether.

Merge tag 'gpio-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.9 kernel cycle.

  There is nothing too exciting in it, but a new macro that fixes a
  build failure on a minor ARM32 platform that appeared yesterday is
  part of it so we better merge it.

  Core changes:

   - Introduce the for_each_requested_gpio() macro to help in dependent
     code all over the place. Also patch a few locations to use it while
     we are at it.

   - Split out the sysfs code into its own file.

   - Split out the character device code into its own file, then make a
     set of refactorings and improvements to this code. We are setting
     the stage to revamp the userspace API a bit in the next cycle.

   - Fix a whole slew of kerneldoc that was wrong or missing.

  New drivers:

   - The PCA953x driver now supports the PCAL9535.

  Driver improvements:

   - A host of incremental modernizations and improvements to the
