Lubomir Rintel cdcbb19388 dt-bindings: Add "mrvl", a legacy vendor prefix for Marvell
While the preferred vendor prefix is "marvell", "mrvl" is used by many
older bindings already. Add it, while also marking it deprecated.

Lubomir Rintel c734a7cc77 dt-bindings: arm: mrvl: Add missing compatible strings
Add compatible strings for the boards we have in tree. At the same time,
fix the MMP3 compatible string: the preferred vendor name for Marvell is
"marvell", not "mrvl", and indeed "marvell,mmp3" has been actively used,
not "mrvl,mmp3".

Lubomir Rintel 39648d052f dt-bindings: arm: l2x0: Tauros 3 is PL310 compatible
The validation is unhappy about mmp3-dell-ariel declaring its
marvell,tauros3-cache node to be compatible with arm,pl310-cache:

  mmp3-dell-ariel.dt.yaml: cache-controller@d0020000: compatible:
       Additional items are not allowed ('arm,pl310-cache' was unexpected)
  mmp3-dell-ariel.dt.yaml: cache-controller@d0020000: compatible:
       ['marvell,tauros3-cache', 'arm,pl310-cache'] is too long

Let's allow this -- Tauros 3 is designed to be compatible with PL310.

Rob Herring 7f464532b0 dt-bindings: Add missing 'additionalProperties: false'
Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

Thomas Hebb f36938aa74 ALSA: hda/realtek - Remove now-unnecessary XPS 13 headphone noise fixups
patch_realtek.c has historically failed to properly configure the PC
Beep Hidden Register for the ALC256 codec (among others). Depending on
your kernel version, symptoms of this misconfiguration can range from
chassis noise, picked up by a poorly-shielded PCBEEP trace, getting
amplified and played on your internal speaker and/or headphones to loud
feedback, which responds to the "Headphone Mic Boost" ALSA control,
getting played through your headphones. For details of the problem, see
the patch in this series titled "ALSA: hda/realtek - Set principled PC
Beep configuration for ALC256", which fixes the configuration.

These symptoms have been most noticed on the Dell XPS 13 9350 and 9360,
popular laptops that use the ALC256. As a result, several model-specific
fixups have been introduced to try and fix the problem, the most
egregious of which locks the "Headphone Mic Boost" control as a hack to
minimize noise from a feedback loop that shouldn't have been there in
the first place.

Now that the underlying issue has been fixed, remove all these fixups.
Remaining fixups needed by the XPS 13 are all picked up by existing pin
quirks.

This change should, for the XPS 13 9350/9360

 - Significantly increase volume and audio quality on headphones
 - Eliminate headphone popping on suspend/resume
 - Allow "Headphone Mic Boost" to be set again, making the headphone
   jack fully usable as a microphone jack too.

Fixes: 8c69729b44 ("ALSA: hda - Fix headphone noise after Dell XPS 13 resume back from S3")
Fixes: 423cd78561 ("ALSA: hda - Fix headphone noise on Dell XPS 13 9360")
Fixes: e4c9fd10eb ("ALSA: hda - Apply headphone noise quirk for another Dell XPS 13 variant")

Thomas Hebb f128090491 ALSA: doc: Document PC Beep Hidden Register on Realtek ALC256
This codec (among others) has a hidden set of audio routes, apparently
designed to allow PC Beep output without a mixer widget on the output
path, which are controlled by an undocumented Realtek vendor register.
The default configuration of these routes means that certain inputs
aren't accessible, necessitating driver control of the register.
However, Realtek has provided no documentation of the register, instead
opting to fix issues by providing magic numbers, most of which have been
at least somewhat erroneous. These magic numbers then get copied by
others into model-specific fixups, leading to a fragmented and buggy set
of configurations.

To get out of this situation, I've reverse engineered the register by
flipping bits and observing how the codec's behavior changes. This
commit documents my findings. It does not change any code.

A bit smaller this time around.. there are still a couple uabi
additions for vulkan waiting in the wings, but I punted on them this
cycle due to running low on time.  (They should be easy enough to
rebase, and if it is a problem for anyone I can push a next+uabi
branch so that tu work can proceed.)

The bigger change is refactoring dpu resource manager and moving dpu
to use atomic global state.  Other than that, it is mostly cleanups
and fixes.

Linus Torvalds 2853d5fafb Support for "split lock" detection:
- Atomic operations (lock prefixed instructions) which span two cache
     lines have to acquire the global bus lock. This is at least 1k cycles
     slower than an atomic operation within a cache line and disrupts
     performance on other cores. Aside of performance disruption this is
     a unpriviledged form of DoS.
 
     Some newer CPUs have the capability to raise an #AC trap when such an
     operation is attempted. The detection is by default enabled in warning
     mode which will warn once when a user space application is caught. A
     command line option allows to disable the detection or to select fatal
     mode which will terminate offending applications with SIGBUS.

Pull scheduler updates from Ingo Molnar:
 "The main changes in this cycle are:

   - Various NUMA scheduling updates: harmonize the load-balancer and
     NUMA placement logic to not work against each other. The intended
     result is better locality, better utilization and fewer migrations.

   - Introduce Thermal Pressure tracking and optimizations, to improve
     task placement on thermally overloaded systems.

   - Implement frequency invariant scheduler accounting on (some) x86
     CPUs. This is done by observing and sampling the 'recent' CPU
     frequency average at ~tick boundaries. The CPU provides this data
     via the APERF/MPERF MSRs. This hopefully makes our capacity
     estimates more precise and keeps tasks on the same CPU better even
     if it might seem overloaded at a lower momentary frequency. (As
     usual, turbo mode is a complication that we resolve by observing
     the maximum frequency and renormalizing to it.)

   - Add asymmetric CPU capacity wakeup scan to improve capacity
     utilization on asymmetric topologies. (big.LITTLE systems)

   - PSI fixes and optimizations.

   - RT scheduling capacity awareness fixes & improvements.

   - Optimize the CONFIG_RT_GROUP_SCHED constraints code.

Linus Torvalds a776c270a0 Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI updates from Ingo Molnar:
 "The EFI changes in this cycle are much larger than usual, for two
  (positive) reasons:

   - The GRUB project is showing signs of life again, resulting in the
     introduction of the generic Linux/UEFI boot protocol, instead of
     x86 specific hacks which are increasingly difficult to maintain.
     There's hope that all future extensions will now go through that
     boot protocol.

   - Preparatory work for RISC-V EFI support.

  The main changes are:

   - Boot time GDT handling changes

   - Simplify handling of EFI properties table on arm64

   - Generic EFI stub cleanups, to improve command line handling, file
     I/O, memory allocation, etc.

   - Introduce a generic initrd loading method based on calling back
     into the firmware, instead of relying on the x86 EFI handover
     protocol or device tree.

   - Introduce a mixed mode boot method that does not rely on the x86
     EFI handover protocol either, and could potentially be adopted by
     other architectures (if another one ever surfaces where one
     execution mode is a superset of another)

   - Clean up the contents of 'struct efi', and move out everything that
     doesn't need to be stored there.

   - Incorporate support for UEFI spec v2.8A changes that permit
     firmware implementations to return EFI_UNSUPPORTED from UEFI
     runtime services at OS runtime, and expose a mask of which ones are
     supported or unsupported via a configuration table.

   - Partial fix for the lack of by-VA cache maintenance in the
     decompressor on 32-bit ARM.

   - Changes to load device firmware from EFI boot service memory
     regions

   - Various documentation updates and minor code cleanups and fixes"

Linus Torvalds a231bed226 spi/regulator: Updates for v5.7
At one point in the release cycle I managed to fat finger things and
 apply some SPI fixes onto a regulator branch and merge that into the SPI
 tree, then pull in a change shared with the MTD tree moving the Mediatek
 quadspi driver over to become the Mediatek spi-nor driver in the SPI
 tree.  This has made a mess which I only just noticed while preparing
 this and I can't see a sensible way to unpick things due to other
 subsequent merge commits especially the pull from MTD so it looks like
 the most sensible thing to do is give up and combine the two pull
 requests - I hope this is OK.  Sorry about this, I've changed some bits
 of workflow which should hopefully help me spot such issues earlier in
 future.
 
 Fortunately both subsystems were fairly quiet this cycle, the highlights
 are:
 
 regulator:
 
  - Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869 and
    Qualcomm PMI8994 and SMB208.
 
 SPI:
 
  - Lots of enhancements for spi-fsl-dspi, including XSPI mode support,
    from Vladimir Oltean.
  - Support for amlogic Meson G12A, IBM FSI, Mediatek spi-nor (moved from
    MTD), NXP i.MX8Mx, Rockchip PX30, RK3308 and RK3328, and Qualcomm
    Atheros AR934x/QCA95xx.

  This has made a mess which I only just noticed while preparing this
  and I can't see a sensible way to unpick things due to other
  subsequent merge commits especially the pull from MTD so it looks like
  the most sensible thing to do is give up and combine the two pull
  requests.

  Fortunately both subsystems were fairly quiet this cycle, the
  highlights are:

  regulator:

   - Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869
     and Qualcomm PMI8994 and SMB208.

  SPI:

   - Lots of enhancements for spi-fsl-dspi, including XSPI mode support,
     from Vladimir Oltean.

   - Support for amlogic Meson G12A, IBM FSI, Mediatek spi-nor (moved
     from MTD), NXP i.MX8Mx, Rockchip PX30, RK3308 and RK3328, and
     Qualcomm Atheros AR934x/QCA95xx"

Linus Torvalds 4c6ef3b156 Staging/IIO driver patches for 5.7-rc1
Here is the big staging and IIO driver pull request for 5.7-rc1.
 
 We again end up deleting more code than we added here, thanks to finally
 getting rid of the old and obsolete wireless USB stuff, and the exfat
 code (which is coming in again through the vfs tree in a much cleaner
 version).  But some code does come back, with the octeon drivers being
 found to actually be used in the wild, so those deletions are now
 reverted.
 
 Other than those major things, just loads and loads of tiny checkpatch
 cleanups all over the place, along with new IIO drivers and fixes.
 
 All have been in linux-next with no reported issues.

Convert ROHM bd71837 and bd71847 PMIC binding text docs to yaml. Split
the binding document to two separate documents (own documents for BD71837
and BD71847) as they have different amount of regulators. This way we can
better enforce the node name check for regulators. ROHM is also providing
BD71850 - which is almost identical to BD71847 - main difference is some
initial regulator states. The BD71850 can be driven by same driver and it
has same buck/LDO setup as BD71847 - add it to BD71847 binding document and
introduce compatible for it.

Kuppuswamy Sathyanarayanan 894020fdd8 PCI/AER: Rationalize error status register clearing
The AER interfaces to clear error status registers were a confusing mess:

  - pci_cleanup_aer_uncorrect_error_status() cleared non-fatal errors
    from the Uncorrectable Error Status register.

  - pci_aer_clear_fatal_status() cleared fatal errors from the
    Uncorrectable Error Status register.

  - pci_cleanup_aer_error_status_regs() cleared the Root Error Status
    register (for Root Ports), the Uncorrectable Error Status register,
    and the Correctable Error Status register.

Rename them to make them consistent:

  From                                     To
  ---------------------------------------- -------------------------------
  pci_cleanup_aer_uncorrect_error_status() pci_aer_clear_nonfatal_status()
  pci_aer_clear_fatal_status()             pci_aer_clear_fatal_status()
  pci_cleanup_aer_error_status_regs()      pci_aer_clear_status()

Since pci_cleanup_aer_error_status_regs() (renamed to
pci_aer_clear_status()) is only used within drivers/pci/, move the
declaration from <linux/aer.h> to drivers/pci/pci.h.

Kuppuswamy Sathyanarayanan b6cf1a42f9 PCI/ERR: Remove service dependency in pcie_do_recovery()
Previously we passed the PCIe service type parameter to pcie_do_recovery(),
where reset_link() looked up the underlying pci_port_service_driver and its
.reset_link() function pointer. Instead of using this roundabout way, we
can just pass the driver-specific .reset_link() callback function when
calling pcie_do_recovery() function.

This allows us to call pcie_do_recovery() from code that is not a PCIe port
service driver, e.g., Error Disconnect Recover (EDR) support.

Remove pcie_port_find_service() and pcie_port_service_driver.reset_link
since they are now unused.

The documentation of rw_semaphores is wrong as it claims that the non-owner

distortion.

Split the 'Owner semantics' section up and add separate sections for
semaphore and rw_semaphore to reflect reality.

Aside of that the following updates are done:

   PREEMPT_RT

 - Wordsmith the bitspinlock and lock nesting sections

Jason Gunthorpe 6bfef2f919 mm/hmm: remove HMM_FAULT_SNAPSHOT
Now that flags are handled on a fine-grained per-page basis this global
flag is redundant and has a confusing overlap with the pfn_flags_mask and
default_flags.

Normalize the HMM_FAULT_SNAPSHOT behavior into one place. Callers needing
the SNAPSHOT behavior should set a pfn_flags_mask and default_flags that
always results in a cleared HMM_PFN_VALID. Then no pages will be faulted,
and HMM_FAULT_SNAPSHOT is not a special flow that overrides the masking
mechanism.

As this is the last flag, also remove the flags argument. If future flags
are needed they can be part of the struct hmm_range function arguments.

Linus Torvalds 32db9f10d5 ARM: DT and driver fixes for v5.6
For the devicetree files, there are a total of 20 patches, almost
 entirely for 32-bit machines:
 
 - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
   both for correctness and for style that are addressed in separate
   patches. This causes most of the changed lines of the DT updates
   this time.
 
 - More Allwinner updates fixing the identification of the security
   system on sun8i/A33, a recent regression of the A83t ethernet, and a
   few board specific issues on the TBS-A711 macine.
 
 - Several bug fixes for OMAP dts files, most notably fixing the timings
   for the NAND flash on the Nokia N900 that regressed a while ago after
   the move to configuring them from DT.  Some other OMAPs now set the
   correct dma limits on the L3 bus, and a regression fix addresses lost
   Ethernet on dm814x
 
 - One incorrect setting in the newly added Raspberry Pi Zero W that
   may cause issues with the SD card controller.

Pull ARM DT and driver fixes from Arnd Bergmann:
 "For the devicetree files, there are a total of 20 patches, almost
  entirely for 32-bit machines:

   - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
     both for correctness and for style that are addressed in separate
     patches. This causes most of the changed lines of the DT updates
     this time.

   - More Allwinner updates fixing the identification of the security
     system on sun8i/A33, a recent regression of the A83t ethernet, and
     a few board specific issues on the TBS-A711 macine.

   - Several bug fixes for OMAP dts files, most notably fixing the
     timings for the NAND flash on the Nokia N900 that regressed a while
     ago after the move to configuring them from DT. Some other OMAPs
     now set the correct dma limits on the L3 bus, and a regression fix
     addresses lost Ethernet on dm814x

   - One incorrect setting in the newly added Raspberry Pi Zero W that
     may cause issues with the SD card controller.

   - A missing property on the bcm2835 firmware node caused incorrect
     DMA settings.

   - An old bug on the oxnas platform causing spurious interrupts is
     finally addressed.

   - A regression on the Exynos Midas board broke the OLED panel power

The exception tables and fixup tables use a commonly recurring pattern
in the kernel of storing the address of labels as date in custom ELF

Sorting readonly arrays to minimize runtime penalties is quite clever.

Christian Borntraeger 7a2653612b s390/gmap: return proper error code on ksm unsharing
If a signal is pending we might return -ENOMEM instead of -EINTR.
We should propagate the proper error during KSM unsharing.
unmerge_ksm_pages returns -ERESTARTSYS on signal_pending. This gets
translated by entry.S to -EINTR. It is important to get this error
code so that userspace can retry.

To make this clearer we also add -EINTR to the documentation of the
PV_ENABLE call, which calls unmerge_ksm_pages.

Daniel Vetter 9e1ed9fb1e drm: Add docs for managed resources
All collected together to provide a consistent story in one patch,
instead of the somewhat bumpy refactor-evolution leading to this.

Also some thoughts on what the next steps could be:

- Create a macro called devm_drm_dev_alloc() which essentially wraps
  the kzalloc(); devm_drm_dev_init(); drmm_add_final_kfree() combo.
  Needs to be a macro since we'll have to do some typeof trickery and
  casting to make this fully generic for all drivers that embed struct
  drm_device into their own thing.

- A lot of the simple drivers now have essentially just
  drm_dev_unplug(); drm_atomic_helper_shutdown(); as their
  $bus_driver->remove hook. We could create a devm_mode_config_reset
  which sets drm_atomic_helper_shutdown as it's cleanup action, and a
  devm_drm_dev_register with drm_dev_unplug as it's cleanup action,
  and simple drivers wouldn't have a need for a ->remove function at
  all, and we could delete them.

- For more complicated drivers we need drmm_ versions of a _lot_ more
  things. All the userspace visible objects (crtc, plane, encoder,
  crtc), anything else hanging of those (maybe a drmm_get_edid, at
  least for panels and other built-in stuff).

Also some more thoughts on why we're not reusing devm_ with maybe a
fake struct device embedded into the drm_device (we can't use the
kdev, since that's in each drm_minor).

- Code review gets extremely tricky, since every time you see a devm_
  you need to carefully check whether the fake device (with the
  drm_device lifetim) or the real device (with the lifetim of the
  underlying physical device and driver binding) are used. That's not
  going to help at all, and we have enormous amounts of drivers who
  use devm_ where they really shouldn't. Having different types makes
  sure the compiler type checks this for us and ensures correctness.

- The set of functions are very much non-overlapping. E.g.
  devm_ioremap makes total sense, drmm_ioremap has the wrong lifetime,
  since hw resources need to be cleaned out at driver unbind and wont
  outlive that like a drm_device. Similar, but other way round for
  drmm_connector_init (which is the only correct version, devm_ for
  drm_connector is just buggy). Simply not having the wrong version
  again prevents bugs.

Finally I guess this opens a huge todo for all the drivers. I'm
semi-tempted to do a tree-wide s/devm_kzalloc/drmm_kzalloc/ since most
likely that'll fix an enormous amount of bugs and most likely not
cause any issues at all (aside from maybe holding onto memory slightly
too long).

v2:
- Doc improvements from Laurent.
- Also add kerneldoc for the new drmm_add_action_or_reset.

v3:
- Remove kerneldoc for drmm_remove_action.

Daniel Vetter c3b790ea07 drm: Manage drm_mode_config_init with drmm_
drm_mode_config_cleanup is idempotent, so no harm in calling this
twice. This allows us to gradually switch drivers over by removing
explicit drm_mode_config_cleanup calls.

With this step it's now also possible that (at least for simple
drivers) automatic resource cleanup can be done correctly without a
drm_driver->release hook. Therefore allow this now in
devm_drm_dev_init().

Also with drmm_ explicit drm_driver->release hooks are kinda not the
best option: Drivers can always just register their current release
hook with drmm_add_action, but even better they could split them up to
simplify the unwinding for the driver load failure case. So deprecate
that hook to discourage future users.

v2: Fixup the example in the kerneldoc too.

v3:
- For paranoia, double check that minor->dev == dev in the release
  hook, because I botched the pointer math in the drmm library.
- Call drm_mode_config_cleanup when drmm_add_action fails, we'd be
  missing some mutex_destroy and ida_cleanup otherwise (Laurent)

v4: Add a drmm_add_action_or_reset (like devm_ has) to encapsulate this
pattern (Noralf).

v5: Fix oversight in the new drmm_add_action_or_reset macro (Noralf)

v4: Review from Sam:
- drmm_mode_config_init wrapper (also suggested by Thomas)
- improve commit message, explain better why ->relase is deprecated

v5:
- Make drmm_ the main function, with the old one as compat wrapper
  (Sam)
- Add FIXME comments to drm_mode_config_cleanup/init() that drivers
  shouldn't use these anymore.
- Move drmm_add_action_or_reset helper to an earlier patch.

Daniel Vetter c6603c740e drm: add managed resources tied to drm_device
We have lots of these. And the cleanup code tends to be of dubious
quality. The biggest wrong pattern is that developers use devm_, which
ties the release action to the underlying struct device, whereas
all the userspace visible stuff attached to a drm_device can long
outlive that one (e.g. after a hotunplug while userspace has open
files and mmap'ed buffers). Give people what they want, but with more
correctness.

Mostly copied from devres.c, with types adjusted to fit drm_device and
a few simplifications - I didn't (yet) copy over everything. Since
the types don't match code sharing looked like a hopeless endeavour.

For now it's only super simplified, no groups, you can't remove
actions (but kfree exists, we'll need that soon). Plus all specific to
drm_device ofc, including the logging. Which I didn't bother to make
compile-time optional, since none of the other drm logging is compile
time optional either.

One tricky bit here is the chicken&egg between allocating your
drm_device structure and initiliazing it with drm_dev_init. For
perfect onion unwinding we'd need to have the action to kfree the
allocation registered before drm_dev_init registers any of its own
release handlers. But drm_dev_init doesn't know where exactly the
drm_device is emebedded into the overall structure, and by the time it
returns it'll all be too late. And forcing drivers to be able clean up
everything except the one kzalloc is silly.

Work around this by having a very special final_kfree pointer. This
also avoids troubles with the list head possibly disappearing from
underneath us when we release all resources attached to the
drm_device.

v2: Do all the kerneldoc at the end, to avoid lots of fairly pointless
shuffling while getting everything into shape.

v3: Add static to add/del_dr (Neil)
Move typo fix to the right patch (Neil)

v4: Enforce contract for drmm_add_final_kfree:

Use ksize() to check that the drm_device is indeed contained somewhere
in the final kfree(). Because we need that or the entire managed
release logic blows up in a pile of use-after-frees. Motivated by a
discussion with Laurent.

v5: Review from Laurent:
- %zu instead of casting size_t
- header guards
- sorting of includes
- guarding of data assignment if we didn't allocate it for a NULL
  pointer
- delete spurious newline
- cast void* data parameter correctly in ->release call, no idea how
  this even worked before

v6: Review from Sam
- Add the kerneldoc for the managed sub-struct back in, even if it
  doesn't show up in the generated html somehow.
- Explain why __always_inline.
- Fix bisectability around the final kfree() in drm_dev_relase(). This
  is just interim code which will disappear again.
- Some whitespace polish.
- Add debug output when drmm_add_action or drmm_kmalloc fail.

v7: My bisectability fix wasn't up to par as noticed by smatch.

v8: Remove unecessary {} around if else

v9: Use kstrdup_const, which requires kfree_const and introducing a free_dr()
helper (Thomas).

v10: kfree_const goes boom on the plain "kmalloc" assignment, somehow
we need to wrap that in kstrdup_const() too!! Also renumber revision
log, I somehow reset it midway thruh.

To allow new drivers to support elf64, add rproc_elf_sanity_check

it will support both elf versions.
Driver which need to support both elf32/elf64 should use this new

Paul Mackerras 9a5788c615 KVM: PPC: Book3S HV: Add a capability for enabling secure guests
At present, on Power systems with Protected Execution Facility
hardware and an ultravisor, a KVM guest can transition to being a
secure guest at will.  Userspace (QEMU) has no way of knowing
whether a host system is capable of running secure guests.  This
will present a problem in future when the ultravisor is capable of
migrating secure guests from one host to another, because
virtualization management software will have no way to ensure that
secure guests only run in domains where all of the hosts can
support secure guests.

This adds a VM capability which has two functions: (a) userspace
can query it to find out whether the host can support secure guests,
and (b) userspace can enable it for a guest, which allows that
guest to become a secure guest.  If userspace does not enable it,
KVM will return an error when the ultravisor does the hypercall
that indicates that the guest is starting to transition to a
secure guest.  The ultravisor will then abort the transition and
the guest will terminate.

It's a follow-up for discussion in [1].

drgn tool bpf_inspect.py was merged to drgn repo in [2]. Document it
in kernel tree to make BPF developers aware that the tool exists and
can help with getting BPF state unavailable via UAPI.

For now it's just one tool but the doc is written in a way that allows
to cover more tools in the future if needed.

Please refer to the doc itself for more details.

The patch was tested by `make htmldocs` and sanity-checking that
resulting html looks good.

v2 -> v3:
  - two sections: "Description" and "Getting started" (Daniel);
  - add examples in "Getting started" section (Daniel);
  - add "Customization" section to show how tool can be customized.

v1 -> v2:
  - better "BPF drgn tools" section (Alexei)

David Gow 0d5792c9bc Documentation: kunit: Make the KUnit documentation less UML-specific
Remove some of the outmoded "Why KUnit" rationale, and move some
UML-specific information to the kunit_tool page. Also update the Getting
Started guide to mention running tests without the kunit_tool wrapper.

Miquel Raynal 245bbe80e0 SPI NOR core changes:
- move all the manufacturer specific quirks/code out of the core,
 to make the core logic more readable and thus ease maintenance.
 - move the SFDP logic out of the core, it provides a better
 separation between the SFDP parsing and core logic.
 - trim what is exposed in spi-nor.h. The SPI NOR controllers drivers
 must not be able to use structures that are meant just for the
 SPI NOR core.
 - use the spi-mem direct mapping API to let advanced controllers
 optimize the read/write operations when they support direct mapping.
 - add generic formula for the Status Register block protection
 handling. It fixes some long standing locking limitations and eases
 the addition of the 4bit block protection support.
 - add block protection support for flashes with 4 block protection
 bits in the Status Register.
 
 SPI NOR controller drivers changes:
 - the mtk-quadspi driver is replaced by the new spi-mem
 spi-mtk-nor driver. Merge tag 'mtk-mtd-spi-move' into spi-nor/next
 to avoid conflicts.

Sam Ravnborg 99f155d077 dt-bindings: display: drop data-mapping from panel-dpi
data-mapping may not be the best way to describe the
data format used between panels and display interface.

Drop it from the panel-dpi binding so we do not start to rely on it.
We can then work out how to best describe this mapping and when
we know it, we can add it to this binding.

Konstantin Khlebnikov 2b8bd42361 block/diskstats: more accurate approximation of io_ticks for slow disks
Currently io_ticks is approximated by adding one at each start and end of
requests if jiffies counter has changed. This works perfectly for requests
shorter than a jiffy or if one of requests starts/ends at each jiffy.

If disk executes just one request at a time and they are longer than two
jiffies then only first and last jiffies will be accounted.

Fix is simple: at the end of request add up into io_ticks jiffies passed
since last update rather than just one jiffy.

Example: common HDD executes random read 4k requests around 12ms.

fio --name=test --filename=/dev/sdb --rw=randread --direct=1 --runtime=30 &
iostat -x 10 sdb

Note changes of iostat's "%util" 8,43% -> 99,99% before/after patch:

sdb               0,00     0,00   82,60    0,00   330,40     0,00     8,00     0,96   12,09   12,09    0,00   1,02   8,43

After:

Device:         rrqm/s   wrqm/s     r/s     w/s    rkB/s    wkB/s avgrq-sz avgqu-sz   await r_await w_await  svctm  %util

Now io_ticks does not loose time between start and end of requests, but
for queue-depth > 1 some I/O time between adjacent starts might be lost.

For load estimation "%util" is not as useful as average queue length,
but it clearly shows how often disk queue is completely empty.

Arnd Bergmann d2687b896d Allwinner Fixes for 5.6 - part 2
This follows up on the previous 5.6 fixes tag with a fix for the A33
 Security System (crypto offloading hardware). The hardware was found
 to not be compatible with existing hardware and a new compatible was
 needed.
 
 The driver change was picked up right before the previous -rc6 and
 the DT bindings and DT changes were not picked up. The goal is to have
 all the changes in the same release, that is v5.6.

Damien Le Moal ccf4ad7da0 zonfs: Fix handling of read-only zones
The write pointer of zones in the read-only consition is defined as
invalid by the SCSI ZBC and ATA ZAC specifications. It is thus not
possible to determine the correct size of a read-only zone file on
mount. Fix this by handling read-only zones in the same manner as
offline zones by disabling all accesses to the zone (read and write)
and initializing the inode size of the read-only zone to 0).

For zones found to be in the read-only condition at runtime, only
disable write access to the zone and keep the size of the zone file to
its last updated value to allow the user to recover previously written
data.

Also fix zonefs documentation file to reflect this change.

this interface in an attempt to make the implementations easier.

Describe what each info section is supposed to contain, and make
some references to other HW interfaces (PCI caps).

Document how firmware management is expected to look, to make
it clear how devlink-info and devlink-flash work in concert.

Name some future work.

David S. Miller 5ef8c66541 wireless-drivers-next patches for v5.7
Second set of patches for v5.7. Lots of cleanup patches this time, but
 of course various new features as well fixes.
 
 When merging with wireless-drivers this pull request has a conflict in:
 
 drivers/net/wireless/intel/iwlwifi/pcie/drv.c
 
 To solve that just drop the changes from commit cf52c8a776 in
 wireless-drivers and take the hunk from wireless-drivers-next as is.
 The list of specific subsystem device IDs are not necessary after
 commit d6f2134a38 (in wireless-drivers-next) anymore, the detection
 is based on other characteristics of the devices.
 
 Major changes:
 
 qtnfmac
 
 * support WPA3 SAE and OWE in AP mode
 
 ath10k
 
 * support for getting btcoex settings from Device Tree
 
 * support QCA9377 SDIO device
 
 ath11k
 
 * add HE rate accounting
 
 * add thermal sensor and cooling devices

in combination with 'additionalProperties: false' and

'additionalProperties' applies to all properties that are not

First when we combine synopsys-dw-mshc.yaml,
synopsys-dw-mshc-common.yaml and mmc-controller.yaml it gives

Jann Horn 9c40365a65 threads: Update PID limit comment according to futex UAPI change
The futex UAPI changed back in commit 76b81e2b0e ("[PATCH] lightweight
robust futexes updates 2"), which landed in v2.6.17: FUTEX_TID_MASK is now
0x3fffffff instead of 0x1fffffff. Update the corresponding comment in
include/linux/threads.h.

Documentation mentions that only the lower 29 bits are available for TID
storage, but as the UAPI header released the bit already via
FUTEX_TID_MASK, this is moot as well. Fix it up.

Jacob Keller ff2e5c700e ice: add basic handler for devlink .info_get
The devlink .info_get callback allows the driver to report detailed
version information. The following devlink versions are reported with
this initial implementation:

 "fw.mgmt" -> The version of the firmware that controls PHY, link, etc
 "fw.mgmt.api" -> API version of interface exposed over the AdminQ
 "fw.mgmt.build" -> Unique build id of the source for the management fw
 "fw.undi" -> Version of the Option ROM containing the UEFI driver
 "fw.psid.api" -> Version of the NVM image format.
 "fw.bundle_id" -> Unique identifier for the combined flash image.
 "fw.app.name" -> The name of the active DDP package.
 "fw.app" -> The version of the active DDP package.

With this, devlink dev info can report at least as much information as
is reported by ETHTOOL_GDRVINFO.

Compare the output from ethtool vs from devlink:

  $ ethtool -i ens785s0
  driver: ice
  version: 0.8.1-k

Mauro Carvalho Chehab 4658b0eb94 docs: conf.py: avoid thousands of duplicate label warning on Sphinx
The autosectionlabel extension is nice, as it allows to refer to
a section by its name without requiring any extra tag to create
a reference name.

However, on its default, it has two serious problems:

1) the namespace is global. So, two files with different
   "introduction" section would create a label with the
   same name. This is easily solvable by forcing the extension
   to prepend the file name with:

	autosectionlabel_prefix_document = True

2) It doesn't work hierarchically. So, if there are two level 1
   sessions (let's say, one labeled "open" and another one "ioctl")
   and both have a level 2 "synopsis" label, both section 2 will
   have the same identical name.

   Currently, there's no way to tell Sphinx to create an
   hierarchical reference like:

		open / synopsis
		ioctl / synopsis

  This causes around 800 warnings. So, the fix should be to
  not let autosectionlabel to produce references for anything
  that it is not at a chapter level within any doc, with:

	autosectionlabel_maxdepth = 2

Mauro Carvalho Chehab c44166fe5f docs: prevent warnings due to autosectionlabel
Changeset 58ad30cf91 ("docs: fix reference to core-api/namespaces.rst")
enabled a new feature at Sphinx: it will now generate index for each
document title, plus to each chapter inside it.

There's a drawback, though: one document cannot have two sections
with the same name anymore.

A followup patch will change the logic of autosectionlabel to
avoid most creating references for every single section title,
but still we need to be able to reference the chapters inside
a document.

There are a few places where there are two chapters with the
same name. This patch renames one of the chapters, in order to
avoid symbol conflict within the same document.

Hans de Goede e4c2c0ff00 firmware: Add new platform fallback mechanism and firmware_request_platform()
In some cases the platform's main firmware (e.g. the UEFI fw) may contain
an embedded copy of device firmware which needs to be (re)loaded into the
peripheral. Normally such firmware would be part of linux-firmware, but in
some cases this is not feasible, for 2 reasons:

1) The firmware is customized for a specific use-case of the chipset / use
with a specific hardware model, so we cannot have a single firmware file
for the chipset. E.g. touchscreen controller firmwares are compiled
specifically for the hardware model they are used with, as they are
calibrated for a specific model digitizer.

2) Despite repeated attempts we have failed to get permission to
redistribute the firmware. This is especially a problem with customized
firmwares, these get created by the chip vendor for a specific ODM and the
copyright may partially belong with the ODM, so the chip vendor cannot
give a blanket permission to distribute these.

This commit adds a new platform fallback mechanism to the firmware loader
which will try to lookup a device fw copy embedded in the platform's main
firmware if direct filesystem lookup fails.

Drivers which need such embedded fw copies can enable this fallback
mechanism by using the new firmware_request_platform() function.

Note that for now this is only supported on EFI platforms and even on
these platforms firmware_fallback_platform() only works if
CONFIG_EFI_EMBEDDED_FIRMWARE is enabled (this gets selected by drivers
which need this), in all other cases firmware_fallback_platform() simply
always returns -ENOENT.

Yuantian Tang fd96a316d2 dt-bindings: thermal: make cooling-maps property optional
Cooling-maps doesn't have to be a required property because there may
be no cooling device on system, or there are no enough cooling devices for
each thermal zone in multiple thermal zone cases since cooling devices
can't be shared.
So make this property optional to remove such limitations.

For thermal zones with no cooling-maps, there could be critic trips
that can trigger CPU reset or shutdown. So they still can take actions.

Eric Biggers e98ad46475 fscrypt: add FS_IOC_GET_ENCRYPTION_NONCE ioctl
Add an ioctl FS_IOC_GET_ENCRYPTION_NONCE which retrieves the nonce from
an encrypted file or directory.  The nonce is the 16-byte random value
stored in the inode's encryption xattr.  It is normally used together
with the master key to derive the inode's actual encryption key.

The nonces are needed by automated tests that verify the correctness of
the ciphertext on-disk.  Except for the IV_INO_LBLK_64 case, there's no
way to replicate a file's ciphertext without knowing that file's nonce.

The nonces aren't secret, and the existing ciphertext verification tests
in xfstests retrieve them from disk using debugfs or dump.f2fs.  But in
environments that lack these debugging tools, getting the nonces by
manually parsing the filesystem structure would be very hard.

To make this important type of testing much easier, let's just add an
ioctl that retrieves the nonce.

Greg Kroah-Hartman 526ee72dfd debugfs: remove return value of debugfs_create_file_size()
No one checks the return value of debugfs_create_file_size, as it's not

Greg Kroah-Hartman 281d90e24f First set of new IIO device support, fatures and cleanups for the 5.7 cycle
Includes changes for the counter subsystem
 
 Core Feature
 * Explicitly handle sysfs values in dB, including correctly handling the
   needed postfix dB.
 * Add a TODO to suggest suitable activities for new contributors to IIO now
   the vast majority of drivers are out of staging (and the remaining ones
   there are 'hard'). Also update the TODO in staging to remove stale entries.
 
 Staging graduations
 * ad7192 ADC.
 
 New device support
 * ad5770r
   - New driver for this 6 channel DAC including DT bindings.
 * ad8366
   - Add supprot for the hmc1119 attenuator.
 * al3010
   - New driver supporting this Dyna-image light sensors.
   - Power management and DT bindings added in additional patches.
 * atlas-sensor
   - Add support for atlas DO-SM device.  Reads disolved oxygen in a solution.
 * gpap002x00f
   - New driver and bindings to support the GP2AP002A00F and GP2AP002S00F light
     and proximity sensors. There is some limited existing support in
     input.  The intent is to drop this driver once IIO driver is in place.
 * hmc425a
   - New driver for this attenuator.
 * icp10100
   - New driver for this presure sensor.
 * ltc2632
   - Add support for the ltc2636 8 channel DAC. Includes bindings and some
     tidying up of the driver.
 * inv_mpu6050
   - Support IAM20680, ICM20609, ICM20689 and ICM20690.
     Includes related tidy up and rework of low pass filter bandwidth
     handling to give suitable values for all chips.
 
 Binding conversions to yaml or missing bindings docs.
 * atlas-sensor, including consolidation of previous 3 separate docs into 1.
 * ad7923, previously no doc.
 * max1363, split into max1238 and max1363 to simplify yaml.
 * stm32-adc
 
 Features
 * (counter) 104-quad-8
   - Support a filter clock prescaler.
   - Support reporting of encoder cable status.
 * ad7124
   - Low pass filter support.
   - Debugfs interface to access registers directly.
 * ad8366
   - Support control of hardware gain.
 * inv_mpu6050
   - Runtime pm with autosuspend.
 * npcm adc
   - Add reset support. This is a breaking change if DT is not in sync,
     however this device is a BMC so the ecosystem is closed enought that
     this should not be a problem.
 * srf04
   - Add power management with DT bindings for the GPIO.
 * stm32-timer-trigger
   - Power management.
 * (counter) stm32-timer-cnt
   - Power management.
 * vcnl4000
   - Enable runtime PM for devices that don't use on demand measurement.
 
 Cleanups and minor fixes
 * core
   - Avoid double read when using debugfs.  Whilst we provide no guarantees
     on lack of side effects using the debugfs interfaces, this one is
     generate unexpected results so let us tidy it up.
 * dac/Kconfig
   - Alphabetic order.
 * ad5755
   - Grammar and minor other fixes.
 * ad7124
   - Fail probe if get_voltage fails as no meaningful readings can be had
     without knowing the external reference.
   - Switch to selection between different channel attributes rather than
     building the arrays at runtime.
   - Remove the spi_device_id table as the driver cannot be probled without
     more information that can be provided without dt.
   - Update sysfs docs to provide more inormation and bring remaining docs for
     this part out of staging.
 * ad9292
   - Use new SPI transfer delay structure.
 * adis library
   - Add unlocked version of adis_initial_startup and refactor the function.
   - Add a product ID santiy check.
   - Add support for different self test registers.
   - Use new SPI delay structure.
   - Add new docs and tidy up existing.
 * adis16136
   - Initialize adis_data statically.
 * adis16400
   - Initialize adis_data statically.
 * adis16460
   - Use core __adis_initial_Startup now it supports everything needed.
 * adis16480
   - Initialize adis_data statically.
   - Use core __adis_initial_startup now it supports everything needed.

   - Ensure autoloading works by adding the of_match_table.
 * atlas-sensor
   - Drop false requirement for interrupt line, the value can be polled using
     a sysfs or hrtimer type trigger.
 * exynos-adc
   - Silence warning message on deferring probe.
 * gp2ap002
   - Greatly simplify the Lux LUT.
   - Reorder actions around buffer setup and tear down as part of a sub-system
     wide standardization of these.
 * inv_mpu6050
   - Various lttle tidyups.
   - Simpliy I2C aux MUX handling by enabling it only at startup. It never
     needs to be disabled.
   - Simplify polling rate when magnetometer enabled by putting only under
     control of userspace.
   - Always execute full reset on devices supporting spi. It does no harm
     when using i2c and makes for simpler code.
   - Reduce over the top sleep times for vddio regulator power up.
   - Greatly simplify power and engine management.
   - Fix some delays in polled reads (only visible due to other changes)
   - Stop preventing sampling rate changes whilst running as there is no
     adverse consequence of doing so.
   - Prevent attempting to read the temperature if neither accel nor
     gyro is enabled.

     wide standardization of these.
 * max1118
   - Use new SPI transfer delay structure.
 * mcp320x
   - Use new SPI transfer delay structure.
 * si1133
   - Read full 24 bit signed integer instead o dropping last 8 bits of value.
     Not a critical fix as just adds precision.
 * st_sensors
   - Use st_sensors_dev_name_probe instead of open coded version in st_accel
   - Handle potential memory allocation failure.
 * st_lsm6dsx
   - Fix some wrong structure element naming in documentation.
   - Add missing return value check.
 * stm32_timer_cnt
   - Drop some unused left over IIO headers from this count subsystem driver.
   - Ensure the clock is enabled in master mode.  Theoretical issue rather
     than one known to happen in the wild.
 * tlc4541
   - Use new SPI delay structure.

Andrzej Pietrasiewicz 55f7f72753 drm/core: Add drm_afbc_framebuffer and a corresponding helper
The new struct contains afbc-specific data.

The new function can be used by drivers which support afbc to complete
the preparation of struct drm_afbc_framebuffer. It must be called after
allocating the said struct and calling drm_gem_fb_init_with_funcs().

Andy Shevchenko a3cb39d258 serial: core: Allow detach and attach serial device for console
In the future we would like to disable power management on the serial devices
used as kernel consoles to avoid weird behaviour in some cases. However,
disabling PM may prevent system to go to deep sleep states, which in its turn
leads to the higher power consumption.

Tony Lindgren proposed a work around, i.e. allow user to detach such consoles
to make PM working again. In case user wants to see what's going on, it also
provides a mechanism to attach console back.

Jessica Yu 5190044c29 modpost: move the namespace field in Module.symvers last
In order to preserve backwards compatability with kmod tools, we have to
move the namespace field in Module.symvers last, as the depmod -e -E
option looks at the first three fields in Module.symvers to check symbol
versions (and it's expected they stay in the original order of crc,
symbol, module).

In addition, update an ancient comment above read_dump() in modpost that
suggested that the export type field in Module.symvers was optional. I
suspect that there were historical reasons behind that comment that are
no longer accurate. We have been unconditionally printing the export
type since 2.6.18 (commit bd5cbcedf4), which is over a decade ago now.

Fix up read_dump() to treat each field as non-optional. I suspect the
original read_dump() code treated the export field as optional in order
to support pre <= 2.6.18 Module.symvers (which did not have the export
type field). Note that although symbol namespaces are optional, the
field will not be omitted from Module.symvers if a symbol does not have
a namespace. In this case, the field will simply be empty and the next
delimiter or end of line will follow.

regulator: mp886x: Document MP8867 support
MP8867 is an I2C-controlled adjustable voltage regulator made by
Monolithic Power Systems. The difference between MP8867 and MP8869
are:
1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of MP8867
is determined by the I2C control.
2.For MP8867, when setting voltage, if the steps is within 5, we need
to manually set the GO_BIT to 0.

Paolo Bonzini 1c482452d5 KVM: s390: Features and Enhancements for 5.7 part1
1. Allow to disable gisa
 2. protected virtual machines
   Protected VMs (PVM) are KVM VMs, where KVM can't access the VM's
   state like guest memory and guest registers anymore. Instead the
   PVMs are mostly managed by a new entity called Ultravisor (UV),
   which provides an API, so KVM and the PV can request management
   actions.
 
   PVMs are encrypted at rest and protected from hypervisor access
   while running.  They switch from a normal operation into protected
   mode, so we can still use the standard boot process to load a
   encrypted blob and then move it into protected mode.
 
   Rebooting is only possible by passing through the unprotected/normal
   mode and switching to protected again.
 
   One mm related patch will go via Andrews mm tree ( mm/gup/writeback:
   add callbacks for inaccessible pages)

Jay Zhou 3c9bd4006b KVM: x86: enable dirty log gradually in small chunks
It could take kvm->mmu_lock for an extended period of time when
enabling dirty log for the first time. The main cost is to clear
all the D-bits of last level SPTEs. This situation can benefit from
manual dirty log protect as well, which can reduce the mmu_lock
time taken. The sequence is like this:

1. Initialize all the bits of the dirty bitmap to 1 when enabling
   dirty log for the first time
2. Only write protect the huge pages
3. KVM_GET_DIRTY_LOG returns the dirty bitmap info
4. KVM_CLEAR_DIRTY_LOG will clear D-bit for each of the leaf level
   SPTEs gradually in small chunks

Under the Intel(R) Xeon(R) Gold 6152 CPU @ 2.10GHz environment,
I did some tests with a 128G windows VM and counted the time taken
of memory_global_dirty_log_start, here is the numbers:

VM Size        Before    After optimization
128G           460ms     10ms

Andrey Konovalov f2c2e71764 usb: gadget: add raw-gadget interface
USB Raw Gadget is a kernel module that provides a userspace interface for
the USB Gadget subsystem. Essentially it allows to emulate USB devices
from userspace. Enabled with CONFIG_USB_RAW_GADGET. Raw Gadget is
currently a strictly debugging feature and shouldn't be used in
production.

Raw Gadget is similar to GadgetFS, but provides a more low-level and
direct access to the USB Gadget layer for the userspace. The key
differences are:

1. Every USB request is passed to the userspace to get a response, while
   GadgetFS responds to some USB requests internally based on the provided
   descriptors. However note, that the UDC driver might respond to some
   requests on its own and never forward them to the Gadget layer.

2. GadgetFS performs some sanity checks on the provided USB descriptors,
   while Raw Gadget allows you to provide arbitrary data as responses to
   USB requests.

3. Raw Gadget provides a way to select a UDC device/driver to bind to,
   while GadgetFS currently binds to the first available UDC.

4. Raw Gadget uses predictable endpoint names (handles) across different
   UDCs (as long as UDCs have enough endpoints of each required transfer
   type).

5. Raw Gadget has ioctl-based interface instead of a filesystem-based one.

Sibi Sankar a03a5b6313 dt-bindings: soc: qcom: apr: Add protection domain bindings
Qualcomm SoCs (starting with MSM8998) allow for multiple protection
domains (PDs) to run on the same Q6 sub-system. This allows for
services like AVS AUDIO to have their own separate address space and
crash/recover without disrupting the other PDs running on the same Q6
ADSP. Add "qcom,protection-domain" bindings to capture the dependencies
between the APR service and the PD on which the apr service runs.

when reading the GICv4.1 GICD_TYPER2 register, which is unexpected...

Work around it by adding a new quirk for the following variants:

 ThunderX: CN88xx
 OCTEON TX: CN83xx, CN81xx
 OCTEON TX2: CN93xx, CN96xx, CN98xx, CNF95xx*

and use this flag to avoid accessing GICD_TYPER2. Note that all
reserved registers (including redistributors and ITS) are impacted
by this erratum, but that only GICD_TYPER2 has to be worked around
so far.

Alex Hung 1ffb8d032d acpi/x86: add a kernel parameter to disable ACPI BGRT
BGRT is for displaying seamless OEM logo from booting to login screen;
however, this mechanism does not always work well on all configurations
and the OEM logo can be displayed multiple times. This looks worse than
without BGRT enabled.

This patch adds a kernel parameter to disable BGRT in boot time. This is
easier than re-compiling a kernel with CONFIG_ACPI_BGRT disabled.
