c793011242 This is the bulk of pin control changes for the v5.15 kernel cycle, 
no core changes at all this time, just driver work!
 
 New drivers:
 
 - New subdriver for Intel Keem Bay (an ARM-based SoC)
 
 - New subdriver for Qualcomm MDM9607 and SM6115
 
 - New subdriver for ST Microelectronics STM32MP135
 
 - New subdriver for Freescale i.MX8ULP ("Ultra Low Power")
 
 - New subdriver for Ingenic X2100
 
 - Support for Qualcomm PMC8180, PMC8180C, SA8155p-adp PMIC GPIO
 
 - Support Samsung Exynos850
 
 - Support Renesas RZ/G2L
 
 Enhancements:
 
 - A major refactoring of the Rockchip driver, breaking part of it out
   to a separate GPIO driver in drivers/gpio
 
 - Pin bias support on Renesas r8a77995
 
 - Add SCI pins support to Ingenic JZ4755 and JZ4760

75d6e7d9ce Nothing changed in the clk framework core this time around. We did get 
some updates to the basic clk types to use determine_rate for the
 divider type and add a power of two fractional divider flag though.
 Otherwise, this is a collection of clk driver updates. More than half
 the diffstat is in the Qualcomm clk driver where we add a bunch of data
 to describe clks on various SoCs and fix bugs. The other big new thing
 in here is the Mediatek MT8192 clk driver. That's been under review for
 a while and it's nice to see that it's finally upstream.
 
 Beyond that it's the usual set of minor fixes and tweaks to clk drivers.
 There are some non-clk driver bits in here which have all been acked by
 the respective maintainers.
 
 New Drivers:
  - Support video, gpu, display clks on qcom sc7280 SoCs
  - GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs
  - Multimedia clks (MMCC) on qcom MSM8994/MSM8992
  - RPMh clks on qcom SM6350 SoCs
  - Support for Mediatek MT8192 SoCs
  - Add display (DU and DSI) clocks on Renesas R-Car V3U
  - Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and
    resets on Renesas RZ/G2L
 
 Updates:
  - Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators
  - Add power of two flag to fractional divider clk type
  - Migrate some clk drivers to clk_divider_ops.determine_rate
  - Migrate to clk_parent_data in gcc-sdm660
  - Fix CLKOUT clocks on i.MX8MM and i.MX8MN by using imx_clk_hw_mux2
  - Switch from .round_rate to .determine_rate in clk-divider-gate
  - Fix clock tree update for TF-A controlled clocks for all i.MX8M
  - Add missing M7 core clock for i.MX8MN
  - YAML conversion of rk3399 clock controller binding
  - Removal of GRF dependency for the rk3328/rk3036 pll types
  - Drop CLK_IS_CRITICAL flag from Tegra fuse clk
  - Make CLK_R9A06G032 Kconfig symbol invisible
  - Convert various DT bindings to YAML

Pull erofs updates from Gao Xiang:
 "In this cycle, direct I/O and fsdax support for uncompressed files are
  now added in order to avoid double-caching for loop device and VM
  container use cases. All uncompressed cases are now turned into iomap
  infrastructure, which looks much simpler and cleaner.

  In addition, fiemap support is added for both (un)compressed files by
  using iomap infrastructure as well so end users can easily get file
  distribution. We've also added chunk-based uncompressed files support
  for data deduplication as the next step of VM container use cases.

  Summary:

   - support direct I/O for all uncompressed files

   - support fsdax for non-tailpacking regular files

This updates the following:

1) The ASL code to follow latest ACPI requirements, i.e.
   - static buffer to be defined outside of the method
   - The _ADR and _HID shouldn't be together for the same device

2) EFI section relies on the additional kernel configuration option,
   i.e. CONFIG_EFI_CUSTOM_SSDT_OVERLAYS

3) Refer to ACPI machine language as AML (capitalized)

Pull printk updates from Petr Mladek:

 - Optionally, provide an index of possible printk messages via
   <debugfs>/printk/index/. It can be used when monitoring important
   kernel messages on a farm of various hosts. The monitor has to be
   updated when some messages has changed or are not longer available by
   a newly deployed kernel.

 - Add printk.console_no_auto_verbose boot parameter. It allows to
   generate crash dump even with slow consoles in a reasonable time
   frame.

 - Remove printk_safe buffers. The messages are always stored directly
   to the main logbuffer, even in NMI or recursive context. Also it
   allows to serialize syslog operations by a mutex instead of a spin
   lock.

 - Misc clean up and build fixes.

    Elbert and Fuji server boards.
 
  - Snapdragon 665 based Sony Xperia 10II
 
  - Snapdragon MSM8916 based Xiaomi Redmi 2
 
  - Snapdragon MSM8226 based Samsung Galaxy S3 Neo
 
  - NXP i.MX based 32-bit boards:
    - DHCOM based PicoITX
    - DHSOM based DRC0ỉ
    - SolidRun SolidSense
    - SKOV i.MX6 boards.
 
  - NXP i.MX based 64-bit boards:
    - Nitrogen8 SoM and MNT Reform2
    - LS1088A based Traverse Ten64
    - i.MX8M based GW7902.
 
  - NVIDIA Jetson TX2 NX Developer Kit
 
  - 4KOpen STiH418-b2264 development board
 
  - ux500 based Samsung phones: Gavini, Codina and Kyle
 
  - TI AM335x based Sancloud BBE Lite
 
  - ixp4xx dts files to replace all old board files
 
 Other changes:
 
  - Treewide fixes for dtc warnings
 
  - Rockchips i/o domain support
 
  - TI OMAP/AM3 CPSW switch driver support
 
  - Improved device support for allwinner, aspeed, qualcomm, NXP,

57c78a234e arm64 updates for 5.15: 
- Support for 32-bit tasks on asymmetric AArch32 systems (on top of the
   scheduler changes merged via the tip tree).
 
 - More entry.S clean-ups and conversion to C.
 
 - MTE updates: allow a preferred tag checking mode to be set per CPU
   (the overhead of synchronous mode is smaller for some CPUs than
   others); optimisations for kernel entry/exit path; optionally disable
   MTE on the kernel command line.
 
 - Kselftest improvements for SVE and signal handling, PtrAuth.
 
 - Fix unlikely race where a TLBI could use stale ASID on an ASID
   roll-over (found by inspection).
 
 - Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher
   exception levels; drop unnecessary sigdelsetmask() call in the
   signal32 handling; remove BUG_ON when failing to allocate SVE state
   (just signal the process); SYM_CODE annotations.
 
 - Other trivial clean-ups: use macros instead of magic numbers, remove
   redundant returns, typos.

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:

  core:
   - extract i915 eDP backlight into core

4cd67adc44 This tag contains habanalabs driver changes for v5.15: 
- Add a new uAPI (under the cs ioctl) to enable to user to reserve
   signals and signal them from within its workloads, while the driver
   performs the waiting. This allows finer granularity of pipelining
   between the different engines and resource utilization.
 
 - Add a new uAPI (under the wait_for_cs ioctl) to allow waiting
   on multiple command submissions (workloads) at the same time. This
   is an optimization for the user process so it won't need to call
   multiple times to the wait_for_cs ioctl.
 
 - Add new feature of "state dump", which can be triggered through new
   debugfs node. This is a similar concept to the kernel panic dump.
   This new mechanism retrieves information from the device in case
   one of the workloads that was sent by the user got stuck. This is
   very helpful for debugging the hang.
 
 - Add a new debugfs node to perform lookup of user pointers that are
   mapped to habana device's pmmu.
 
 - Fix to the tracking of user process when running inside a container.
 
 - Allow user to map more than 4GB of memory to the device MMU in single
   IOCTL call.
 
 - Minimize number of register reads done in GAUDI during user operation.
 
 - Allow user to retrieve the device's server type that the device is
   connected to.
 
 - Several fixes to the code of waiting on interrupts on behalf of the
   user.
 
 - Fixes and improvements to the hint mechanism in our VA allocation.
 
 - Update the firmware header files to the latest version while
   maintaining backward compatibility with older firmware versions.
 
 - Multiple fixes to various bugs.

0d290223a6 sound updates for 5.15-rc1 
There are a few intensive changes in ALSA core side at this time that
 helped the significant code reduction.  Meanwhile we keep getting new
 stuff, so the total size still grows...
 Anyway, the below are some highlights in this development cycle.
 
 ALSA core:
 - New helpers to manage page allocations and card object with devres
 - Refactoring for memory allocation with wc-pages
 - A new PCM hardware flag SNDRV_PCM_INFO_EXPLICIT_SYNC for controlling
   the explicit sync of the stream control; it'll be used for ASoC SOF
   and non-coherent memory in future
 
 ASoC:
 - Lots of cleanups and improvements to the Intel drivers, including
   some new systems support
 - New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek Mt8195,
   Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P, Renesas RZ/G2L,
   Rockchip RK3568 S/PDIF
 
 USB-audio:
 - Re-organized the quirk handling and  a new option quirk_flags
 - Fix for a regression in 5.14 code change for JACK
 - Quirks for Sony WALKMAN, Digidesign mbox
 
 HD-audio:
 - Enhanced support for CS8409 codec
 - More consistent shutdown behavior with the runtime PM
 - The model option can accept the PCI or codec SSID as an alias
 - Quirks for ASUS ROG, HP Spectre x360
 
 Others:
 - Lots of code reduction in legacy drivers with devres helpers
 - FireWire MOTU 896HD support

ebf435d3b5 IIO / Staging driver update for 5.15-rc1 
Here is the big set of staging and IIO driver updates for 5.15-rc1.
 Also included in here are the counter driver subsystem updates as the
 IIO drivers needed them.
 
 Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
 driver and replaced it with a newer version of the driver that had been
 maintained out-of-tree by Larry with the end goal of actually being able
 to get this driver out of staging eventually.  Despite that driver being
 "newer" the line count of this pull request is going up.
 
 Some drivers moved out of staging as well, which is always nice to see,
 that is why there are additions to the mfc and misc driver subsystems.
 All of these were acked by the various subsystem maintainers involved.
 
 But by far, as normal, it's coding style cleanups all over the
 drivers/staging/ tree in here.
 
 Full details of these changes are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 problems.

[ Note: the r8188eu merge clashed with commit 89939e8906 ("staging:
  rtlwifi: use siocdevprivate") from the networking tree. When resolving
  the issue, I noted that the whole r8188eu rtw_android code is dead
  since commit ae7471cae0 ("staging: r8188eu: remove rtw_ioctl

  End result: the merge resolution was to throw all of that away,

efa916af13 - Add DM infrastructure for IMA-based remote attestion. These changes 
are the basis for deploying DM-based storage in a "cloud" that must
   validate configurations end-users run to maintain trust. These DM
   changes allow supported DM targets' configurations to be measured
   via IMA. But the policy and enforcement (of which configurations are
   valid) is managed by something outside the kernel (e.g. Keylime).

Pull idmapping documentation updates from Christian Brauner:
 "The bulk of the idmapped work this cycle was adding support for
  idmapped mounts to btrfs.

  While this required the addition of a (simple) new vfs helper all the
  work is going through David Sterba's btrfs tree. It was way simpler to
  do it this way rather then forcing David to coordinate between his
  btrfs and my tree. Plus I don't care who merges it as long as I feel I
  can trust the maintainer and the btrfs folks were really fast and
  helpful in reviewing this work.

  As always, associated with the btrfs port for idmapped mounts is a new
  fstests extension specifically concerned with btrfs ioctls (e.g.
  subvolume creation, deletion etc.) on idmapped mounts which can be
  found in the fstests repo as 5f8179ce8b00 ("btrfs: introduce btrfs
  specific idmapped mounts tests").

  Consequently, this cycle the idmapping pull is boring. It only
  contains documentation updates, specifically about how idmappings and
  idmapped mounts work"

 "Initial merge of kernel smb3 file server, ksmbd.

  The SMB family of protocols is the most widely deployed network
  filesystem protocol, the default on Windows and Macs (and even on many
  phones and tablets), with clients and servers on all major operating
  systems, but lacked a kernel server for Linux. For many cases the
  current userspace server choices were suboptimal either due to memory
  footprint, performance or difficulty integrating well with advanced
  Linux features.

  ksmbd is a new kernel module which implements the server-side of the
  SMB3 protocol. The target is to provide optimized performance, GPLv2
  SMB server, and better lease handling (distributed caching). The
  bigger goal is to add new features more rapidly (e.g. RDMA aka
  "smbdirect", and recent encryption and signing improvements to the
  protocol) which are easier to develop on a smaller, more tightly
  optimized kernel server than for example in Samba.

  The Samba project is much broader in scope (tools, security services,
  LDAP, Active Directory Domain Controller, and a cross platform file
  server for a wider variety of purposes) but the user space file server
  portion of Samba has proved hard to optimize for some Linux workloads,
  including for smaller devices.

  This is not meant to replace Samba, but rather be an extension to
  allow better optimizing for Linux, and will continue to integrate well
  with Samba user space tools and libraries where appropriate. Working
  with the Samba team we have already made sure that the configuration
  files and xattrs are in a compatible format between the kernel and
  user space server.

  Various types of functional and regression tests are regularly run
  against it. One example is the automated 'buildbot' regression tests
  which use the Linux client to test against ksmbd, e.g.

     http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/8/builds/56

  but other test suites, including Samba's smbtorture functional test
  suite are also used regularly"

8596e589b7 Updates for timekeeping, timers and related drivers: 
Core code:
 
   - Cure a couple of incorrectness issues in the posix CPU timer code to
     prevent that the tick dependency for NOHZ full is kept alive for no
     reason.
 
   - Avoid expensive double reprogramming of the clockevent device in
     hrtimer_start_range_ns().
 
   - Avoid pointless SMP function calls when the clock was set to avoid
     disturbing CPUs which do not have any affected timers queued.
 
   - Make the clocksource watchdog test work correctly when CONFIG_HZ is
     less than 100.
 
 Drivers:
 
   - Prefer the ARM architected timer over the Exynos timer which is way
     more expensive to access.
 
   - Add device tree bindings for new Ingenic SoCs
 
   - The usual improvements and cleanups all over the place

Pull timer updates from Thomas Gleixner:
 "Updates for timekeeping, timers and related drivers:

  Core code:

   - Cure a couple of correctness issues in the posix CPU timer code to
     prevent that the tick dependency for NOHZ full is kept alive for no
     reason.

   - Avoid expensive double reprogramming of the clockevent device in
     hrtimer_start_range_ns().

   - Avoid pointless SMP function calls when the clock was set to avoid
     disturbing CPUs which do not have any affected timers queued.

   - Make the clocksource watchdog test work correctly when CONFIG_HZ is
     less than 100.

  Drivers:

   - Prefer the ARM architected timer over the Exynos timer which is way
     more expensive to access.

   - Add device tree bindings for new Ingenic SoCs

   - The usual improvements and cleanups all over the place"

e5e726f7bb Updates for locking and atomics: 
The regular pile:
 
   - A few improvements to the mutex code
 
   - Documentation updates for atomics to clarify the difference between
     cmpxchg() and try_cmpxchg() and to explain the forward progress
     expectations.
 
   - Simplification of the atomics fallback generator
 
   - The addition of arch_atomic_long*() variants and generic arch_*()
     bitops based on them.
 
   - Add the missing might_sleep() invocations to the down*() operations of
     semaphores.
 
 The PREEMPT_RT locking core:
 
   - Scheduler updates to support the state preserving mechanism for
     'sleeping' spin- and rwlocks on RT. This mechanism is carefully
     preserving the state of the task when blocking on a 'sleeping' spin- or
     rwlock and takes regular wake-ups targeted at the same task into
     account. The preserved or updated (via a regular wakeup) state is
     restored when the lock has been acquired.
 
   - Restructuring of the rtmutex code so it can be utilized and extended
     for the RT specific lock variants.
 
   - Restructuring of the ww_mutex code to allow sharing of the ww_mutex
     specific functionality for rtmutex based ww_mutexes.
 
   - Header file disentangling to allow substitution of the regular lock
     implementations with the PREEMPT_RT variants without creating an
     unmaintainable #ifdef mess.
 
   - Shared base code for the PREEMPT_RT specific rw_semaphore and rwlock
     implementations. Contrary to the regular rw_semaphores and rwlocks the
     PREEMPT_RT implementation is writer unfair because it is infeasible to
     do priority inheritance on multiple readers. Experience over the years
     has shown that real-time workloads are not the typical workloads which
     are sensitive to writer starvation. The alternative solution would be
     to allow only a single reader which has been tried and discarded as it
     is a major bottleneck especially for mmap_sem. Aside of that many of
     the writer starvation critical usage sites have been converted to a
     writer side mutex/spinlock and RCU read side protections in the past
     decade so that the issue is less prominent than it used to be.
 
   - The actual rtmutex based lock substitutions for PREEMPT_RT enabled
     kernels which affect mutex, ww_mutex, rw_semaphore, spinlock_t and
     rwlock_t. The spin/rw_lock*() functions disable migration across the
     critical section to preserve the existing semantics vs. per CPU
     variables.
 
   - Rework of the futex REQUEUE_PI mechanism to handle the case of early
     wake-ups which interleave with a re-queue operation to prevent the
     situation that a task would be blocked on both the rtmutex associated
     to the outer futex and the rtmutex based hash bucket spinlock.
 
     While this situation cannot happen on !RT enabled kernels the changes
     make the underlying concurrency problems easier to understand in
     general. As a result the difference between !RT and RT kernels is
     reduced to the handling of waiting for the critical section. !RT
     kernels simply spin-wait as before and RT kernels utilize rcu_wait().
 
   - The substitution of local_lock for PREEMPT_RT with a spinlock which
     protects the critical section while staying preemptible. The CPU
     locality is established by disabling migration.
 
   The underlying concepts of this code have been in use in PREEMPT_RT for
   way more than a decade. The code has been refactored several times over
   the years and this final incarnation has been optimized once again to be
   as non-intrusive as possible, i.e. the RT specific parts are mostly
   isolated.
 
   It has been extensively tested in the 5.14-rt patch series and it has
   been verified that !RT kernels are not affected by these changes.

   - In-kernel torture-test updates

   - Torture-test scripting, perhaps most notably the pinning of
     torture-test guest OSes so as to force differences in memory
     latency. For example, in a two-socket system, a four-CPU guest OS
     will have one pair of its CPUs pinned to threads in a single core
     on one socket and the other pair pinned to threads in a single core
     on the other socket. This approach proved able to force race
     conditions that earlier testing missed. Some of these race
     conditions are still being tracked down"

From Maor Gottlieb
====================

Fix the use of nents and orig_nents in the sg table append helpers. The
nents should be used by the DMA layer to store the number of DMA mapped
sges, the orig_nents is the number of CPU sges.

Since the sg append logic doesn't always create a SGL with exactly
orig_nents entries store a total_nents as well to allow the table to be
properly free'd and reorganize the freeing logic to share across all the
use cases.

Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next:

1) Clean up and consolidate ct ecache infrastructure by merging ct and
   expect notifiers, from Florian Westphal.

2) Missing counters and timestamp in nfnetlink_queue and _log conntrack
   information.

3) Missing error check for xt_register_template() in iptables mangle,
   as a incremental fix for the previous pull request, also from
   Florian Westphal.

4) Add netfilter hooks for the SRv6 lightweigh tunnel driver, from
   Ryoga Sato. The hooks are enabled via nf_hooks_lwtunnel sysctl
   to make sure existing netfilter rulesets do not break. There is
   a static key to disable the hooks by default.

   The pktgen_bench_xmit_mode_netif_receive.sh shows no noticeable
   impact in the seg6_input path for non-netfilter users: similar
   numbers with and without this patch.

   This is a sample of the perf report output:

d532bcd0b2 netfilter: conntrack: sanitize table size default settings 
conntrack has two distinct table size settings:
nf_conntrack_max and nf_conntrack_buckets.

The former limits how many conntrack objects are allowed to exist
in each namespace.

The second sets the size of the hashtable.

As all entries are inserted twice (once for original direction, once for
reply), there should be at least twice as many buckets in the table than
the maximum number of conntrack objects that can exist at the same time.

Change the default multiplier to 1 and increase the chosen bucket sizes.
This results in the same nf_conntrack_max settings as before but reduces
the average bucket list length.

0e35f63f7f hwmon: add driver for Aquacomputer D5 Next 
This driver exposes hardware sensors of the Aquacomputer D5 Next
watercooling pump, which communicates through a proprietary USB HID
protocol.

Available sensors are pump and fan speed, power, voltage and current, as
well as coolant temperature. Also available through debugfs are the serial
number, firmware version and power-on count.

Attaching a fan is optional and allows it to be controlled using
temperature curves directly from the pump. If it's not connected,
the fan-related sensors will report zeroes.

The pump can be configured either through software or via its physical
interface. Configuring the pump through this driver is not implemented,
as it seems to require sending it a complete configuration. That
includes addressable RGB LEDs, for which there is no standard sysfs
interface. Thus, that task is better suited for userspace tools.

This driver has been tested on x86_64, both in-kernel and as a module.

When set, a driver only matches the entry when dev->driver_override is

aa6eca5b81 dt-bindings: PCI: mediatek: Update the Device tree bindings 
There are two independent PCIe controllers in MT2712 and MT7622
platform. Each of them should contain an independent MSI domain.

In old dts architecture, MSI domain will be inherited from the root
bridge, and all of the devices will share the same MSI domain.
Hence that, the PCIe devices will not work properly if the irq number
which required is more than 32.

Split the PCIe node for MT2712 and MT7622 platform to comply with
the hardware design and fix MSI issue.

e2cd76907f dt-bindings: usb: mtk-xhci: add compatible for mt8195 
There are 4 USB controllers on MT8195, the controllers (IP1~IP3,
exclude IP0) have a wrong default SOF/ITP interval which is
calculated from the frame counter clock 24Mhz by default, but
in fact, the frame counter clock is 48Mhz, so we should set
the accurate interval according to 48Mhz. Here add a new compatible
for MT8195, it's also supported in driver. But the first controller
(IP0) has no such issue, we prefer to use generic compatible,
e.g. mt8192's compatible.

246b184fff pktgen: document the latest pktgen usage options 
Currently, the pktgen.rst documentation doesn't cover the latest pktgen
sample usage options such as count and IPv6, and so on. Also, this
documentation includes the old sample scripts which are no longer use
because it was removed by the commit a4b6ade835 ("samples/pktgen :
remove remaining old pktgen sample scripts")

Thus, this commit documents pktgen sample usage using the latest options
and removes old sample scripts, and fixes a minor typo.

2af2b50acf of: fdt: Add generic support for handling usable memory range property 
Add support for handling the "linux,usable-memory-range" property in the
"/chosen" node to the FDT core code.  This can co-exist safely with the
architecture-specific handling, until the latter has been removed.

f7e7ce93aa of: fdt: Add generic support for handling elf core headers property 
There are two methods to specify the location of the elf core headers:
using the "elfcorehdr=" kernel parameter, as handled by generic code in
kernel/crash_dump.c, or using the "linux,elfcorehdr" property under the
"/chosen" node in the Device Tree, as handled by architecture-specific
code in arch/arm64/mm/init.c.

Extend support for "linux,elfcorehdr" to all platforms supporting DT by
adding platform-agnostic handling for handling this property to the FDT
core code.  This can co-exist safely with the architecture-specific
handling, until the latter has been removed.

This requires moving the call to of_scan_flat_dt() up, as the code
scanning the "/chosen" node now needs to be aware of the values of
"#address-cells" and "#size-cells".
