8bed5a5cfc Docs/EDID: Calculate CRC while building the code 
The previous version made it necessary to first generate an
EDID data set without correct CRC and then to fix the CRC in
a second step. This patch adds the CRC calculation to the
makefile in such a way that a correct EDID data set is generated
in a single build step. Successfully tested with all existing
and a couple of new data sets.

d2f112a568 Docs/EDID: Fixed erroneous bits of XOFFSET, XPULSE, YOFFSET and YPULSE 
The problem was found when EDID data sets for displays other
than the provided samples were generated. The patch has
no effect on the provided samples that still match the data
used in drivers/gpu/drm/drm_edid_load.c.

The provided samples use small values for XOFFSET, XPULSE,
YOFFSET and YPULSE, where the error doesn't occur. This fix
corrects the use of that values in case of high values, because
the most significant bits were treated incorrectly.

So in edid.S msbs4 should use bit 8 and 9 of XOFFSET and XPULS.
For YOFFSET and YPULSE msbs4 should use bit 4 and 5.

lsbs2 was introduced for a better overview, without
functional change.

Removing also the useless value 63 of all files, because
it is added in the *.S description files and then it is
subtracted in edid.S.

Pull block layer fixes from Jens Axboe:
 "The biggest part of this pull request is the revert of the blkcg
  cleanup series. It had one fix earlier for a stacked device issue, but
  another one was reported. Rather than play whack-a-mole with this,
  revert the entire series and try again for the next kernel release.

  Apart from that, only small fixes/changes.

  Summary:

   - Indentation fixup for mtip32xx (Colin Ian King)

   - The blkcg cleanup series revert (Dennis Zhou)

   - Two NVMe fixes. One fixing a regression in the nvme request
     initialization in this merge window, causing nvme-fc to not work.
     The other is a suspend/resume p2p resource issue (James, Keith)

   - Fix sg discard merge, allowing us to merge in cases where we didn't
     before (Jianchao Wang)

   - Call rq_qos_exit() after the queue is frozen, preventing a hang
     (Ming)

   - Fix brd queue setup, fixing an oops if we fail setting up all
     devices (Ming)"

c2aa1a444c vfs: rework data cloning infrastructure 
Rework the vfs_clone_file_range and vfs_dedupe_file_range infrastructure to use
 a common .remap_file_range method and supply generic bounds and sanity checking
 functions that are shared with the data write path. The current VFS
 infrastructure has problems with rlimit, LFS file sizes, file time stamps,
 maximum filesystem file sizes, stripping setuid bits, etc and so they are
 addressed in these commits.
 
 We also introduce the ability for the ->remap_file_range methods to return short
 clones so that clones for vfs_copy_file_range() don't get rejected if the entire
 range can't be cloned. It also allows filesystems to sliently skip deduplication
 of partial EOF blocks if they are not capable of doing so without requiring
 errors to be thrown to userspace.
 
 All existing filesystems are converted to user the new .remap_file_range method,
 and both XFS and ocfs2 are modified to make use of the new generic checking
 infrastructure.

Merge tag 'xfs-4.20-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull vfs dedup fixes from Dave Chinner:
 "This reworks the vfs data cloning infrastructure.

  We discovered many issues with these interfaces late in the 4.19 cycle
  - the worst of them (data corruption, setuid stripping) were fixed for
  XFS in 4.19-rc8, but a larger rework of the infrastructure fixing all
  the problems was needed. That rework is the contents of this pull
  request.

  Rework the vfs_clone_file_range and vfs_dedupe_file_range
  infrastructure to use a common .remap_file_range method and supply
  generic bounds and sanity checking functions that are shared with the
  data write path. The current VFS infrastructure has problems with
  rlimit, LFS file sizes, file time stamps, maximum filesystem file
  sizes, stripping setuid bits, etc and so they are addressed in these
  commits.

  We also introduce the ability for the ->remap_file_range methods to
  return short clones so that clones for vfs_copy_file_range() don't get
  rejected if the entire range can't be cloned. It also allows
  filesystems to sliently skip deduplication of partial EOF blocks if
  they are not capable of doing so without requiring errors to be thrown
  to userspace.

  Existing filesystems are converted to user the new remap_file_range
  method, and both XFS and ocfs2 are modified to make use of the new
  generic checking infrastructure"

e468f5c06b The Compiler Attributes series 
This is an effort to disentangle the include/linux/compiler*.h headers
 and bring them up to date.
 
 The main idea behind the series is to use feature checking macros
 (i.e. __has_attribute) instead of compiler version checks (e.g. GCC_VERSION),
 which are compiler-agnostic (so they can be shared, reducing the size
 of compiler-specific headers) and version-agnostic.
 
 Other related improvements have been performed in the headers as well,
 which on top of the use of __has_attribute it has amounted to a significant
 simplification of these headers (e.g. GCC_VERSION is now only guarding
 a few non-attribute macros).
 
 This series should also help the efforts to support compiling the kernel
 with clang and icc. A fair amount of documentation and comments have also
 been added, clarified or removed; and the headers are now more readable,
 which should help kernel developers in general.
 
 The series was triggered due to the move to gcc >= 4.6. In turn, this series
 has also triggered Sparse to gain the ability to recognize __has_attribute
 on its own.
 
 Finally, the __nonstring variable attribute series has been also applied
 on top; plus two related patches from Nick Desaulniers for unreachable()
 that came a bit afterwards.

Pull keys updates from James Morris:
 "Provide five new operations in the key_type struct that can be used to
  provide access to asymmetric key operations. These will be implemented
  for the asymmetric key type in a later patch and may refer to a key
  retained in RAM by the kernel or a key retained in crypto hardware.

     int (*asym_query)(const struct kernel_pkey_params *params,

  Since encrypt, decrypt and sign are identical in their interfaces,
  they're rolled together in the asym_eds_op() operation and there's an
  operation ID in the params argument to distinguish them.

  Verify is different in that we supply the data and the signature
  instead and get an error value (or 0) as the only result on the

d47748e5ae ovl: automatically enable redirect_dir on metacopy=on 
Current behavior is to automatically disable metacopy if redirect_dir is
not enabled and proceed with the mount.

If "metacopy=on" mount option was given, then this behavior can confuse the
user: no mount failure, yet metacopy is disabled.

This patch makes metacopy=on imply redirect_dir=on.

The converse is also true: turning off full redirect with redirect_dir=
{off|follow|nofollow} will disable metacopy.

If both metacopy=on and redirect_dir={off|follow|nofollow} is specified,
then mount will fail, since there's no way to correctly resolve the
conflict.

Pull stackleak gcc plugin from Kees Cook:
 "Please pull this new GCC plugin, stackleak, for v4.20-rc1. This plugin
  was ported from grsecurity by Alexander Popov. It provides efficient
  stack content poisoning at syscall exit. This creates a defense
  against at least two classes of flaws:

   - Uninitialized stack usage. (We continue to work on improving the
     compiler to do this in other ways: e.g. unconditional zero init was
     proposed to GCC and Clang, and more plugin work has started too).

   - Stack content exposure. By greatly reducing the lifetime of valid
     stack contents, exposures via either direct read bugs or unknown
     cache side-channels become much more difficult to exploit. This
     complements the existing buddy and heap poisoning options, but
     provides the coverage for stacks.

  The x86 hooks are included in this series (which have been reviewed by
  Ingo, Dave Hansen, and Thomas Gleixner). The arm64 hooks have already
  been merged through the arm64 tree (written by Laura Abbott and
  reviewed by Mark Rutland and Will Deacon).

  With VLAs having been removed this release, there is no need for
  alloca() protection, so it has been removed from the plugin"

519f64bf15 This time it looks like a quieter release cycle in the clk tree. I guess that's 
because of summer time holidays/vacations. The biggest change in the diffstat
 is in the Qualcomm clk driver, where they got support for CPUs and handful of
 SoCs. After that, the at91 driver got a major rewrite for newer DT bindings
 that should make things easier going forward and the TI code moved to a
 clockdomain based design. The long tail is mostly small driver updates for
 newer clks and some simpler SoC clock drivers such as the Hisilicon and imx
 support.
 
 In the core framework, we only have two small changes this time. One is a new
 clk API to get all clks for a device with the bulk clk APIs. This allows
 drivers that don't care about doing anything besides turning on all the clks to
 just clk_get() them all and turn them on. The other change is the beginning of
 a way to support save and restore of clk settings in the clk framework. TI is
 the only user right now, but we will want to expand upon this design in the
 future to support more save and restore of clk registers.  At least this gets
 us started and works well enough for one SoC, but there's more work in the
 future.
 
 Core:
  - clk_bulk_get_all() API and friends to get all the clks for a device
  - Basic clk state save/restore hooks
 
 New Drivers:
  - Renesas RZ/A2 (R7S9210) SoC, including early clocks
  - Rensas RZ/G1N (R8A7744) and RZ/G2E (R8A774C0) SoCs

  - Qualcomm Krait CPU clk support
  - Qualcomm QCS404 GCC support

  - Hisilicon 3670 SoC support
  - TI SCI clks on K3 SoCs
  - iMX6 MMDC clks
  - Reset Controller (RMU) support for Actions Semi Owl S900 and S700 SoCs
 
 Updates:
  - Rework at91 PMC clock driver for new DT bindings
  - Nvidia Tegra clk driver MBIST workaround fix
  - S2RAM support for Marvell mvebu periph clks
  - Use updated printk format for OF node names

Pull new experimental media request API from Mauro Carvalho Chehab:
 "A new media request API

  This API is needed to support device drivers that can dynamically
  change their parameters for each new frame. The latest versions of
  Google camera and codec HAL depends on such feature.

  At this stage, it supports only stateless codecs.

  It has been discussed for a long time (at least over the last 3-4
  years), and we finally reached to something that seem to work.

  This series contain both the API and core changes required to support
  it and a new m2m decoder driver (cedrus).

  As the current API is still experimental, the only real driver using
  it (cedrus) was added at staging[1]. We intend to keep it there for a
  while, in order to test the API. Only when we're sure that this API
  works for other cases (like encoders), we'll move this driver out of
  staging and set the API into a stone.

  [1] We added support for the vivid virtual driver (used only for
  testing) to it too, as it makes easier to test the API for the ones
  that don't have the cedrus hardware"

Let's document the magic a bit, especially why device_hotplug_lock is
required when adding/removing memory and how it all play together with
requests to online/offline memory from user space.

310c7585e8 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.)
 
 Otherwise, some RDMA work and miscellaneous bugfixes.

343a9f3540 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

 It adds support for audio DSP (both TZ-assisted and non-TZ assisted) and

 WiFi processor on Qualcomm QCS404 and through some renaming of the
 drivers cleans up the naming situation.

eca3654e3c vfs: enable remap callers that can handle short operations 
Plumb in a remap flag that enables the filesystem remap handler to
shorten remapping requests for callers that can handle it.  Now
copy_file_range can report partial success (in case we run up against
alignment problems, resource limits, etc.).

We also enable CAN_SHORTEN for fideduperange to maintain existing
userspace-visible behavior where xfs/btrfs shorten the dedupe range to
avoid stale post-eof data exposure.

42ec3d4c02 vfs: make remap_file_range functions take and return bytes completed 
Change the remap_file_range functions to take a number of bytes to
operate upon and return the number of bytes they operated on.  This is a
requirement for allowing fs implementations to return short clone/dedupe
results to the user, which will enable us to obey resource limits in a
graceful manner.

A subsequent patch will enable copy_file_range to signal to the
->clone_file_range implementation that it can handle a short length,
which will be returned in the function's return value.  For now the
short return is not implemented anywhere so the behavior won't change --
either copy_file_range manages to clone the entire range or it tries an
alternative.

Neither clone ioctl can take advantage of this, alas.

 - Linus Walleij lists himself for the ARM Reference platforms:
   versatile, vexpress, integrator and realview. He has been the main
   contributor for these for a while, and makes it official now.
 
 - Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood
 
 - Manivannan Sadhasivam becomes a secondary maintainer for the
   Actions Semi machines
 
 - Nicolas Ferre lists updates the MAINTAINER listing for the AT91
   platform: Ludovic Desroches is now a co-maintainer for the platform, and
   several other people (Claudiu Beznea, Cristian Birsan, Eugen Hristev,
   Codrin Ciubotariu) take over individual device drivers.
 
 Thanks everyone for working on this, and welcome to the new maintainers!
 
 The "virt" platform on qemy or kvm can now be used in big-endian mode
 without additional tricks, thanks to Jason Donenfeld.
 
 Once again, we gain support for another NXP i.MX6 variant, this time
 it's the i.MX 6ULZ 32-bit single-core version.
 
 On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
 and RZ/G2M (r8a774a1). These are described as microcontrollers on the
 manufacturer website, but appear to be rather powerful. The RZ/G2M is
 used on the reference board for the CIP Super Long Term Support (SLTS)
 Linux Kernels.

  maintainers!

  The "virt" platform on qemy or kvm can now be used in big-endian mode
  without additional tricks, thanks to Jason Donenfeld.

  Once again, we gain support for another NXP i.MX6 variant, this time
  it's the i.MX 6ULZ 32-bit single-core version.

  On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
  and RZ/G2M (r8a774a1). These are described as microcontrollers on the
  manufacturer website, but appear to be rather powerful. The RZ/G2M is
  used on the reference board for the CIP Super Long Term Support (SLTS)
  Linux Kernels"

b22b6beae6 ARM: SoC driver updates for 4.17 
The most noteworthy SoC driver changes this time include:
 
 - 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 respective power management chips.
 
 - A new driver for NXP i.MX8, which need a firmware interface for
   power management.
 
 - The SCPI firmware interface now contains support estimating power
   usage of performance states
 
 - The NVIDIA Tegra "pmc" driver gains a few new features, in particular
   a pinctrl interface for configuring the pads.
 
 - Lots of small changes for Qualcomm, in particular the "smem"
   device driver.
 
 - Some cleanups for the TI OMAP series related to their sysc
   controller.
 
 Additional cleanups and bugfixes in SoC specific drivers include the
 Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

93335e5911 ARM: SoC device tree updates for 4.20 
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.
 
 Synaptics add support for their AS370 SoC, which is part of the (formerly
 Marvell) Berlin line of set-top-box chips used e.g.  in the various Google
 Chromecast. Only the .dtsi gets added at this point, no actual machines.

5bd4af34a0 TTY/Serial patches for 4.20-rc1 
Here is the big tty and serial pull request for 4.20-rc1
 
 Lots of little things here, including a merge from the SPI tree in order
 to keep things simpler for everyone to sync around for one platform.
 
 Major stuff is:
 	- tty buffer clearing after use
 	- atmel_serial fixes and additions
 	- xilinx uart driver updates
 and of course, lots of tiny fixes and additions to individual serial
 drivers.
 
 All of these have been in linux-next with no reported issues for a
 while.

738b04fba1 Staging/IIO patches for 4.20-rc1 
Here is the big staging and IIO driver pull request for 4.20-rc1.
 
 There are lots of things here, we ended up adding more lines than
 removing, thanks to a large influx of Comedi National Instrument device
 support.  Someday soon we need to get comedi out of staging...
 
 Other than the comedi drivers, the "big" things here are:
   - new iio drivers
   - delete dgnc driver (no one used it and no one had the hardware
     anymore)
   - vbox driver updates and fixes
   - erofs fixes
   - tons and tons of tiny checkpatch fixes for almost all staging
     drivers
 
 All of these have been in linux-next, with the last few happening a bit
 "late" due to them getting stuck on my laptop during travel to the
 Mantainers summit.
 
 When merging with your tree, there will be 2 merge conflicts, both files
 will be simple to resolve, just delete them :)

c0e9ab2472 dt-bindings: drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1 
As far as I can tell the bindings that were added in commit
9c04400f7e ("dt-bindings: drm/panel: Document Innolux TV123WAM panel
bindings") weren't actually for Innolux TV123WAM but were actually for
Innolux P120ZDG-BF1.

As far as I can tell the Innolux TV123WAM isn't a real panel and but
it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1.
Let's unmosh.

Here's my evidence:

* Searching for TV123WAM on the Internet turns up a TI panel.  While
  it's possible that an Innolux panel has the same model number as the
  TI Panel, it seems a little doubtful.  Looking up the datasheet from
  the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm.

* As far as I know, the patch adding the Innolux Panel was supposed to
  be for the board that's sitting in front of me as I type this
  (support for that board is not yet upstream).  On the back of that
  panel I see Innolux P120ZDZ-EZ1 rev B1.

* Someone pointed me at a datasheet that's supposed to be for the
  panel in front of me (sorry, I can't share the datasheet).  That
  datasheet has the string "p120zdg-bf1"

* If I search for "P120ZDG-BF1" on the Internet I get hits for panels
  that are 2160x1440.  They don't have datasheets, but the fact that
  the resolution matches is a good sign.

While we doing the rename, also mention that no-hpd can be used with
this panel.  See the previous patch in this series ("drm/panel:
simple: Add "no-hpd" delay for Innolux TV123WAM").
