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.

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")

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.

59e7a8cc2d Merge tag 'drm-msm-next-2020-03-22' of https://gitlab.freedesktop.org/drm/msm into drm-next
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.

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.

642e53ead6 Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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.

   - Misc fixes, cleanups and optimizations - see the changelog for
     details"

Pull locking updates from Ingo Molnar:
 "The main changes in this cycle were:

   - Continued user-access cleanups in the futex code.

   - percpu-rwsem rewrite that uses its own waitqueue and atomic_t
     instead of an embedded rwsem. This addresses a couple of
     weaknesses, but the primary motivation was complications on the -rt
     kernel.

   - Introduce raw lock nesting detection on lockdep
     (CONFIG_PROVE_RAW_LOCK_NESTING=y), document the raw_lock vs. normal
     lock differences. This too originates from -rt.

   - Reuse lockdep zapped chain_hlocks entries, to conserve RAM
     footprint on distro-ish kernels running into the "BUG:

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"

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.

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.

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.

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.

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.

7ecc6aa522 Documentation/locking/locktypes: Further clarifications and wordsmithing
The documentation of rw_semaphores is wrong as it claims that the non-owner
reader release is not supported by RT. That's just history biased memory
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:

 - Add pseudo code to document the spinlock state preserving mechanism on
   PREEMPT_RT

 - Wordsmith the bitspinlock and lock nesting sections

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.

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.
 
 - 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 supply.
 
 - The i.MX6 phycore SoM specified the wrong voltage for the SoC,
   this is now set to the values from the datasheet.
 
 - Some 64-bit machines use a deprecated string to identify the PSCI
   firmware.
 
 There are also several small code fixes addressing mostly serious
 issues:
 
 - Fix the sunxi rsb bus access to no longer return incorrect data when
   mixing 8 and 16 bit I/O.
 
 - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
   quirk in the ti-sysc driver
 
 - Fix a NULL pointer access from a race in the fsl dpio driver
 
 - Fix a v5.5 regression in the exynos-chipid driver that caused an
   invalid error code probing the device on non-exynos platforms
 
 - Fix an out-of-bounds access in the AMD TEE driver

Provide more information about __ex_table sorting post link.

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
sections, then finding these sections, iterating elements within them,
and possibly revisiting them or modifying the data at these addresses.

Sorting readonly arrays to minimize runtime penalties is quite clever.

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.

Documentation/devicetree/bindings/iio/accel/adi,adxl345.yaml

The trivial-devices binding doesn't capture that 'adi,adxl346' has a
fallback compatible 'adi,adxl345', so let's add it to adi,adxl345.yaml.

56effbdd2c Qualcomm ARM64 DT updates for v5.7
This brings initial support for the SM8250 and IPQ6018 platforms.
 
 SDM845 gets audio, PCIe and IP-accelerator support, and the interconnect
 providers are refactored. The Lenovo Yoga C630 has audio enabled and the
 DB845c has PCIe, analog audio and low-speed interfaces enabled. The
 SDM845 MTP has its display enabled and firmware location updated to
 match linux-firmware.
 
 SC7180 gains CPU topology and power properties. Interconnect providers,
 eMMC, SD-card, multimedia clocks, display, Bluetooth, Venus are added.
 Critical trip points are added as well as various fixes.
 
 For MSM8916 FastRPC support is added, ETM power management and reserved
 memory for Samsung A2015 are corrected.
 
 MSM8996 switches to generic QMP phy driver for its UFS support. MSM8998
 temporarily disables part of Coresight to boot without
 clk_ignore_unused.  CEQ for eMMC on QCS404 is enabled.
 
 Fixes throughout the platforms to fix binding compliance, correct
 compatibles for SDHCI nodes and add gpio-ranges.

e6dfccb710 Drop legacy platform data for omaps for v5.7
This series of changes continues dropping legacy platform data for
 omaps by updating devices to probe with ti-sysc interconnect target
 module driver:
 
 - Update omap4, omap5, am437x, and dra7 display subsystem (DSS)
   to probe with device tree data only
 
 - Update am335x, am437x and dra7 to probe EDMA to probe with
   device tree data only
 
 - Drop legacy platform data for am335x and am437x PRUSS as the
   current code just keeps the devices in reset
 
 - Drop legacy platform data for omap4 DSP and IPU as the current
   code just keeps the devices in reset
 
 - Configure am437x and dra7 PRU-ICSS to probe with device tree
   data
 
 For the dropped omap4 DSP and IPU platform data, there will be patches
 coming later on to configure the accelerators using the omap remoteproc
 bindings so hopefully folks can actually use these devices eventually.

To allow new drivers to support elf64, add rproc_elf_sanity_check

it will support both elf versions.

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.

8c061865f5 bpf: Document bpf_inspect drgn tool
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)

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.

Merge tag 'spi-nor/for-5.7' into mtd/next

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.

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.

 - Stefan adds GPIO labels to the Raspberry Pi 4 Model B board DTS
 
 - Nicolas moves the eMMC2 controller into its separate node in order for
   platform firmware to perform the necessary "dma-ranges" property
   patching based on the chip revision since the eMMC controller has
   different addressing constraints.

Merge tag 'arm-soc/for-5.7/devicetree' of https://github.com/Broadcom/stblinux into arm/dt

This pull request contains Broadcom ARM-based SoCs Device Tree changes
for 5.7, please pull the following:

- Stefan adds GPIO labels to the Raspberry Pi 4 Model B board DTS

- Nicolas moves the eMMC2 controller into its separate node in order for
  platform firmware to perform the necessary "dma-ranges" property
  patching based on the chip revision since the eMMC controller has
  different addressing constraints.

- Florian convers a whole bunch of Broadcom boards bindings from text to
  YAML.

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:

Before:

Device:         rrqm/s   wrqm/s     r/s     w/s    rkB/s    wkB/s avgrq-sz avgqu-sz   await r_await w_await  svctm  %util
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
sdb               0,00     0,00   82,50    0,00   330,00     0,00     8,00     1,00   12,10   12,10    0,00  12,12  99,99

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.

   reset quirks
 
 - Enable module reset to work with modules with no sysconfig register
 
 - Also consider non-existing module register when matching quirks

 Note that there is also a DSS driver specific probe fix to allow
 probing devices configured for interconnect target module data that
 was agreed to be merged along with the ti-sysc driver changes.
 
 And then there also changes to handle RTC, EDMA and PRUSS:
 
 - Add module unlock quirk for RTC
 
 - Detect EDMA modules
 
 - Add support for handling PRUSS

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.

 To solve that just drop the changes from commit cf52c8a776 in

 The list of specific subsystem device IDs are not necessary after

 * support for getting btcoex settings from Device Tree
 
 * support QCA9377 SDIO device

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.
