a4235ec06a virtio: allow __virtioXX, __leXX in config space
Currently all config space fields are of the type __uXX.
This confuses people and some drivers (notably vdpa)
access them using CPU endian-ness - which only
works well for legacy or LE platforms.

Update virtio_cread/virtio_cwrite macros to allow __virtioXX
and __leXX field types. Follow-up patches will convert
config space to use these types.

5487196878 virtio_ring: sparse warning fixup
virtio_store_mb was built with split ring in mind so it accepts
__virtio16 arguments. Packed ring uses __le16 values, so sparse
complains.  It's just a store with some barriers so let's convert it to
a macro, we don't loose too much type safety by doing that.

75820314de i2c: core: add generic I2C GPIO recovery
Multiple I2C bus drivers use similar bindings to obtain information needed
for I2C recovery. For example, for platforms using device-tree, the
properties look something like this:

&i2c {
	...
	pinctrl-names = "default", "gpio";
	pinctrl-0 = <&pinctrl_i2c_default>;
	pinctrl-1 = <&pinctrl_i2c_gpio>;
	sda-gpios = <&pio 0 GPIO_ACTIVE_HIGH>;
	scl-gpios = <&pio 1 (GPIO_ACTIVE_HIGH | GPIO_OPEN_DRAIN)>;
	...
}

For this reason, we can add this common initialization in the core. This
way, other I2C bus drivers will be able to support GPIO recovery just by
providing a pointer to platform's pinctrl and calling i2c_recover_bus()
when SDA is stuck low.

262e6ae708 modules: inherit TAINT_PROPRIETARY_MODULE
If a TAINT_PROPRIETARY_MODULE exports symbol, inherit the taint flag
for all modules importing these symbols, and don't allow loading
symbols from TAINT_PROPRIETARY_MODULE modules if the module previously
imported gplonly symbols.  Add a anti-circumvention devices so people
don't accidentally get themselves into trouble this way.

2324d50d05 It's been a busy cycle for documentation - hopefully the busiest for a
while to come.  Changes include:
 
  - Some new Chinese translations
 
  - Progress on the battle against double words words and non-HTTPS URLs
 
  - Some block-mq documentation
 
  - More RST conversions from Mauro.  At this point, that task is
    essentially complete, so we shouldn't see this kind of churn again for a
    while.  Unless we decide to switch to asciidoc or something...:)
 
  - Lots of typo fixes, warning fixes, and more.

3f0d6ecdf1 Generic implementation of common syscall, interrupt and exception
entry/exit functionality based on the recent X86 effort to ensure
 correctness of entry/exit vs. RCU and instrumentation.
 
 As this functionality and the required entry/exit sequences are not
 architecture specific, sharing them allows other architectures to benefit
 instead of copying the same code over and over again.
 
 This branch was kept standalone to allow others to work on it. The
 conversion of x86 comes in a seperate pull request which obviously is based

7de62bc09f SUNRPC dont update timeout value on connection reset
Current behaviour: every time a v3 operation is re-sent to the server
we update (double) the timeout. There is no distinction between whether
or not the previous timer had expired before the re-sent happened.

Here's the scenario:
1. Client sends a v3 operation
2. Server RST-s the connection (prior to the timeout) (eg., connection
is immediately reset)
3. Client re-sends a v3 operation but the timeout is now 120sec.

As a result, an application sees 2mins pause before a retry in case
server again does not reply.

Instead, this patch proposes to keep track off when the minor timeout
should happen and if it didn't, then don't update the new timeout.
Value is updated based on the previous value to make timeouts
predictable.

  The syscall originally came up in a discussion around the new mount
  API and making new file descriptor types cloexec by default. During
  this discussion, Al suggested the close_range() syscall.

  First, it helps to close all file descriptors of an exec()ing task.
  This can be done safely via (quoting Al's example from [1] verbatim):

        /* that exec is sensitive */
        unshare(CLONE_FILES);
        /* we don't want anything past stderr here */
        close_range(3, ~0U);
        execve(....);

  The code snippet above is one way of working around the problem that
  file descriptors are not cloexec by default. This is aggravated by the
  fact that we can't just switch them over without massively regressing
  userspace. For a whole class of programs having an in-kernel method of
  closing all file descriptors is very helpful (e.g. demons, service
  managers, programming language standard libraries, container managers
  etc.).

  Second, it allows userspace to avoid implementing closing all file
  descriptors by parsing through /proc/<pid>/fd/* and calling close() on
  each file descriptor and other hacks. From looking at various
  large(ish) userspace code bases this or similar patterns are very
  common in service managers, container runtimes, and programming
  language runtimes/standard libraries such as Python or Rust.

  In addition, the syscall will also work for tasks that do not have
  procfs mounted and on kernels that do not have procfs support compiled
  in. In such situations the only way to make sure that all file
  descriptors are closed is to call close() on each file descriptor up
  to UINT_MAX or RLIMIT_NOFILE, OPEN_MAX trickery.

  Based on Linus' suggestion close_range() also comes with a new flag
  CLOSE_RANGE_UNSHARE to more elegantly handle file descriptor dropping
  right before exec. This would usually be expressed in the sequence:

        unshare(CLONE_FILES);
        close_range(3, ~0U);

  as pointed out by Linus it might be desirable to have this be a part
  of close_range() itself under a new flag CLOSE_RANGE_UNSHARE which
  gets especially handy when we're closing all file descriptors above a
  certain threshold.

  Test-suite as always included"

Pull checkpoint-restore updates from Christian Brauner:
 "This enables unprivileged checkpoint/restore of processes.

  Given that this work has been going on for quite some time the first
  sentence in this summary is hopefully more exciting than the actual
  final code changes required. Unprivileged checkpoint/restore has seen
  a frequent increase in interest over the last two years and has thus
  been one of the main topics for the combined containers &
  checkpoint/restore microconference since at least 2018 (cf. [1]).

  Here are just the three most frequent use-cases that were brought forward:

   - The JVM developers are integrating checkpoint/restore into a Java
     VM to significantly decrease the startup time.

   - In high-performance computing environment a resource manager will
     typically be distributing jobs where users are always running as
     non-root. Long-running and "large" processes with significant
     startup times are supposed to be checkpointed and restored with
     CRIU.

   - Container migration as a non-root user.

  In all of these scenarios it is either desirable or required to run
  without CAP_SYS_ADMIN. The userspace implementation of
  checkpoint/restore CRIU already has the pull request for supporting
  unprivileged checkpoint/restore up (cf. [2]).

  To enable unprivileged checkpoint/restore a new dedicated capability
  CAP_CHECKPOINT_RESTORE is introduced. This solution has last been
  discussed in 2019 in a talk by Google at Linux Plumbers (cf. [1]
  "Update on Task Migration at Google Using CRIU") with Adrian and
  Nicolas providing the implementation now over the last months. In
  essence, this allows the CRIU binary to be installed with the
  CAP_CHECKPOINT_RESTORE vfs capability set thereby enabling
  unprivileged users to restore processes.

  To make this possible the following permissions are altered:

   - Selecting a specific PID via clone3() set_tid relaxed from userns
     CAP_SYS_ADMIN to CAP_CHECKPOINT_RESTORE.

   - Selecting a specific PID via /proc/sys/kernel/ns_last_pid relaxed
     from userns CAP_SYS_ADMIN to CAP_CHECKPOINT_RESTORE.

   - Accessing /proc/pid/map_files relaxed from init userns
     CAP_SYS_ADMIN to init userns CAP_CHECKPOINT_RESTORE.

   - Changing /proc/self/exe from userns CAP_SYS_ADMIN to userns
     CAP_CHECKPOINT_RESTORE.

  Of these four changes the /proc/self/exe change deserves a few words
  because the reasoning behind even restricting /proc/self/exe changes
  in the first place is just full of historical quirks and tracking this
  down was a questionable version of fun that I'd like to spare others.

  In short, it is trivial to change /proc/self/exe as an unprivileged
  user, i.e. without userns CAP_SYS_ADMIN right now. Either via ptrace()
  or by simply intercepting the elf loader in userspace during exec.
  Nicolas was nice enough to even provide a POC for the latter (cf. [3])
  to illustrate this fact.

  The original patchset which introduced PR_SET_MM_MAP had no
  permissions around changing the exe link. They too argued that it is
  trivial to spoof the exe link already which is true. The argument
  brought up against this was that the Tomoyo LSM uses the exe link in
  tomoyo_manager() to detect whether the calling process is a policy
  manager. This caused changing the exe links to be guarded by userns
  CAP_SYS_ADMIN.

  All in all this rather seems like a "better guard it with something
  rather than nothing" argument which imho doesn't qualify as a great
  security policy. Again, because spoofing the exe link is possible for
  the calling process so even if this were security relevant it was
  broken back then and would be broken today. So technically, dropping
  all permissions around changing the exe link would probably be
  possible and would send a clearer message to any userspace that relies
  on /proc/self/exe for security reasons that they should stop doing
  this but for now we're only relaxing the exe link permissions from
  userns CAP_SYS_ADMIN to userns CAP_CHECKPOINT_RESTORE.

  There's a final uapi change in here. Changing the exe link used to
  accidently return EINVAL when the caller lacked the necessary
  permissions instead of the more correct EPERM. This pr contains a
  commit fixing this. I assume that userspace won't notice or care and
  if they do I will revert this commit. But since we are changing the
  permissions anyway it seems like a good opportunity to try this fix.

  With these changes merged unprivileged checkpoint/restore will be
  possible and has already been tested by various users"

Merge tag 'fork-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull fork cleanups from Christian Brauner:
 "This is cleanup series from when we reworked a chunk of the process
  creation paths in the kernel and switched to struct
  {kernel_}clone_args.

  High-level this does two main things:

   - Remove the double export of both do_fork() and _do_fork() where
     do_fork() used the incosistent legacy clone calling convention.

     Now we only export _do_fork() which is based on struct
     kernel_clone_args.

   - Remove the copy_thread_tls()/copy_thread() split making the
     architecture specific HAVE_COYP_THREAD_TLS config option obsolete.

  This switches all remaining architectures to select
  HAVE_COPY_THREAD_TLS and thus to the copy_thread_tls() calling
  convention. The current split makes the process creation codepaths
  more convoluted than they need to be. Each architecture has their own
  copy_thread() function unless it selects HAVE_COPY_THREAD_TLS then it
  has a copy_thread_tls() function.

  The split is not needed anymore nowadays, all architectures support
  CLONE_SETTLS but quite a few of them never bothered to select
  HAVE_COPY_THREAD_TLS and instead simply continued to use copy_thread()
  and use the old calling convention. Removing this split cleans up the
  process creation codepaths and paves the way for implementing clone3()
  on such architectures since it requires the copy_thread_tls() calling
  convention.

  After having made each architectures support copy_thread_tls() this
  series simply renames that function back to copy_thread(). It also
  switches all architectures that call do_fork() directly over to
  _do_fork() and the struct kernel_clone_args calling convention. This
  is a corollary of switching the architectures that did not yet support
  it over to copy_thread_tls() since do_fork() is conditional on not
  supporting copy_thread_tls() (Mostly because it lacks a separate
  argument for tls which is trivial to fix but there's no need for this
  function to exist.).

  The do_fork() removal is in itself already useful as it allows to to
  remove the export of both do_fork() and _do_fork() we currently have
  in favor of only _do_fork(). This has already been discussed back when
  we added clone3(). The legacy clone() calling convention is - as is
  probably well-known - somewhat odd:

    #
    # ABI hall of shame
    #
    config CLONE_BACKWARDS
    config CLONE_BACKWARDS2
    config CLONE_BACKWARDS3

  that is aggravated by the fact that some architectures such as sparc
  follow the CLONE_BACKWARDSx calling convention but don't really select
  the corresponding config option since they call do_fork() directly.

  So do_fork() enforces a somewhat arbitrary calling convention in the
  first place that doesn't really help the individual architectures that
  deviate from it. They can thus simply be switched to _do_fork()
  enforcing a single calling convention. (I really hope that any new
  architectures will __not__ try to implement their own calling
  conventions...)

  Most architectures already have made a similar switch (m68k comes to
  mind).

  Overall this removes more code than it adds even with a good portion
  of added comments. It simplifies a chunk of arch specific assembly
  either by moving the code into C or by simply rewriting the assembly.

  Architectures that have been touched in non-trivial ways have all been
  actually boot and stress tested: sparc and ia64 have been tested with
  Debian 9 images. They are the two architectures which have been
  touched the most. All non-trivial changes to architectures have seen
  acks from the relevant maintainers. nios2 with a custom built
  buildroot image. h8300 I couldn't get something bootable to test on
  but the changes have been fairly automatic and I'm sure we'll hear
  people yell if I broke something there.

  All other architectures that have been touched in trivial ways have
  been compile tested for each single patch of the series via git rebase
  -x "make ..." v5.8-rc2. arm{64} and x86{_64} have been boot tested
  even though they have just been trivially touched (removal of the
  HAVE_COPY_THREAD_TLS macro from their Kconfig) because well they are
  basically "core architectures" and since it is trivial to get your
  hands on a useable image"

Merge tag 'threads-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull thread updates from Christian Brauner:
 "This contains the changes to add the missing support for attaching to
  time namespaces via pidfds.

  Last cycle setns() was changed to support attaching to multiple
  namespaces atomically. This requires all namespaces to have a point of
  no return where they can't fail anymore.

  Specifically, <namespace-type>_install() is allowed to perform
  permission checks and install the namespace into the new struct nsset
  that it has been given but it is not allowed to make visible changes
  to the affected task. Once <namespace-type>_install() returns,
  anything that the given namespace type additionally requires to be
  setup needs to ideally be done in a function that can't fail or if it
  fails the failure must be non-fatal.

  For time namespaces the relevant functions that fell into this
  category were timens_set_vvar_page() and vdso_join_timens(). The
  latter could still fail although it didn't need to. This function is
  only implemented for vdso_join_timens() in current mainline. As
  discussed on-list (cf. [1]), in order to make setns() support time
  namespaces when attaching to multiple namespaces at once properly we
  changed vdso_join_timens() to always succeed. So vdso_join_timens()
  replaces the mmap_write_lock_killable() with mmap_read_lock().

  Please note that arm is about to grow vdso support for time namespaces
  (possibly this merge window). We've synced on this change and arm64
  also uses mmap_read_lock(), i.e. makes vdso_join_timens() a function
  that can't fail. Once the changes here and the arm64 changes have
  landed, vdso_join_timens() should be turned into a void function so
  it's obvious to callers and implementers on other architectures that
  the expectation is that it can't fail.

  We didn't do this right away because it would've introduced
  unnecessary merge conflicts between the two trees for no major gain.

  As always, tests included"

df23bb18b4 ipv4: route: Ignore output interface in FIB lookup for PMTU route
Currently, processes sending traffic to a local bridge with an
encapsulation device as a port don't get ICMP errors if they exceed
the PMTU of the encapsulated link.

David Ahern suggested this as a hack, but it actually looks like
the correct solution: when we update the PMTU for a given destination
by means of updating or creating a route exception, the encapsulation
might trigger this because of PMTU discovery happening either on the
encapsulation device itself, or its lower layer. This happens on
bridged encapsulations only.

The output interface shouldn't matter, because we already have a
valid destination. Drop the output interface restriction from the
associated route lookup.

For UDP tunnels, we will now have a route exception created for the
encapsulation itself, with a MTU value reflecting its headroom, which
allows a bridge forwarding IP packets originated locally to deliver
errors back to the sending socket.

The behaviour is now consistent with IPv6 and verified with selftests
pmtu_ipv{4,6}_br_{geneve,vxlan}{4,6}_exception introduced later in
this series.

v2:
- reset output interface only for bridge ports (David Ahern)
- add and use netif_is_any_bridge_port() helper (David Ahern)

a0102bda5b ceph: move sb->wb_pagevec_pool to be a global mempool
When doing some testing recently, I hit some page allocation failures
on mount, when creating the wb_pagevec_pool for the mount. That
requires 128k (32 contiguous pages), and after thrashing the memory
during an xfstests run, sometimes that would fail.

128k for each mount seems like a lot to hold in reserve for a rainy
day, so let's change this to a global mempool that gets allocated
when the module is plugged in.

Now that pci_parse_request_of_pci_ranges() callers just setup
pci_host_bridge.windows and dma_ranges directly and don't need the bus
range returned, we can just initialize them when allocating the
pci_host_bridge struct.

With this, pci_parse_request_of_pci_ranges() becomes a static function.

c0842fbc1b random32: move the pseudo-random 32-bit definitions to prandom.h
The addition of percpu.h to the list of includes in random.h revealed
some circular dependencies on arm64 and possibly other platforms.  This
include was added solely for the pseudo-random definitions, which have
nothing to do with the rest of the definitions in this file but are
still there for legacy reasons.

This patch moves the pseudo-random parts to linux/prandom.h and the
percpu.h include with it, which is now guarded by _LINUX_PRANDOM_H and
protected against recursive inclusion.

A further cleanup step would be to remove this from <linux/random.h>
entirely, and make people who use the prandom infrastructure include
just the new header file.  That's a bit of a churn patch, but grepping
for "prandom_" and "next_pseudo_random32" "struct rnd_state" should
catch most users.

But it turns out that that nice cleanup step is fairly painful, because
a _lot_ of code currently seems to depend on the implicit include of
<linux/random.h>, which can currently come in a lot of ways, including
such fairly core headfers as <linux/net.h>.

So the "nice cleanup" part may or may never happen.

d88ca7e1a2 fbmem: pull fbcon_update_vcs() out of fb_set_var()
syzbot is reporting OOB read bug in vc_do_resize() [1] caused by memcpy()
based on outdated old_{rows,row_size} values, for resize_screen() can
recurse into vc_do_resize() which changes vc->vc_{cols,rows} that outdates
old_{rows,row_size} values which were saved before calling resize_screen().

Daniel Vetter explained that resize_screen() should not recurse into
fbcon_update_vcs() path due to FBINFO_MISC_USEREVENT being still set
when calling resize_screen().

Instead of masking FBINFO_MISC_USEREVENT before calling fbcon_update_vcs(),
we can remove FBINFO_MISC_USEREVENT by calling fbcon_update_vcs() only if
fb_set_var() returned 0. This change assumes that it is harmless to call
fbcon_update_vcs() when fb_set_var() returned 0 without reaching
fb_notifier_call_chain().

  - Drop last bits of the ACPI procfs interface (Thomas Renninger).
 
  - Drop some redundant checks from the code parsing ACPI tables
    related to NUMA (Hanjun Guo).
 
  - Avoid redundant object evaluation in the ACPI device properties
    handling code (Heikki Krogerus).
 
  - Avoid unecessary memory overhead related to storing the signatures
    of the ACPI tables recognized by the kernel (Ard Biesheuvel).

Pull ACPI updates from Rafael Wysocki:
 "These eliminate significant AML processing overhead related to using
  operation regions in system memory, update the ACPICA code in the
  kernel to upstream revision 20200717 (including a fix to prevent
  operation region reference counts from overflowing in some cases),
  remove the last bits of the (long deprecated) ACPI procfs interface
  and do some assorted cleanups.

  Specifics:

   - Eliminate significant AML processing overhead related to using
     operation regions in system memory by reworking the management of
     memory mappings in the ACPI code to defer unmap operations (to do
     them outside of the ACPICA locks, among other things) and making
     the memory operation reagion handler avoid releasing memory
     mappings created by it too early (Rafael Wysocki).

   - Update the ACPICA code in the kernel to upstream revision 20200717:

       * Prevent operation region reference counts from overflowing in
         some cases (Erik Kaneda).

       * Replace one-element array with flexible-array (Gustavo A. R.
         Silva).

   - Fix ACPI PCI hotplug reference counting (Rafael Wysocki).

   - Drop last bits of the ACPI procfs interface (Thomas Renninger).

   - Drop some redundant checks from the code parsing ACPI tables
     related to NUMA (Hanjun Guo).

   - Avoid redundant object evaluation in the ACPI device properties
     handling code (Heikki Krogerus).

   - Avoid unecessary memory overhead related to storing the signatures
     of the ACPI tables recognized by the kernel (Ard Biesheuvel).

   - Add missing newline characters when printing module parameter
     values in some places (Xiongfeng Wang).

   - Update the link to the ACPI specifications in some places (Tiezhu
     Yang).

   - Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R.
     Silva).

   - Drop redundant variable initialization from the APEI code (Colin
     Ian King).

   - Drop uninitialized_var() from the ACPI PAD driver (Jason Yan).

   - Replace HTTP links with HTTPS ones in the ACPI code (Alexander A.
     Klimov)"

b171373902 spi: Updates for v5.9
A fairly quiet release for SPI, nothing really going on in the core
 although there's been quite a bit of driver related activity.  This pull
 request includes the addition of some shared code in drivers/memory for
 the Renesas RPC-IF which is used by a newly added SPI driver, the memory
 subsystem doesn't seem to have a fixed maintainer at the minute and this
 seemed like the most sensible way to get that hardware supported.
 
  - Quite a few cleanups and optimizations for the Altera, Qualcomm GENI,
    sun6i and lantiq drivers.
  - Several more GPIO descriptor conversions.
  - Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
  - New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and

822ef14e9d ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
 to have the code merged through the soc tree as upstream, as the code
 tends to be used across multiple SoCs or has SoC specific drivers itself:
 
  - memory controllers:
      Krzysztof Kozlowski takes ownership of the drivers/memory
      subsystem and its drivers, starting out with a set of cleanup
      patches.
      A larger driver for the Tegra memory controller that was accidentally
      missed for v5.8 is now added.
 
  - reset controllers:
      Only minor updates to drivers/reset this time
 
  - firmware:
      The "turris mox" firmware driver gains support for signed firmware blobs
      The tegra firmware driver gets extended to export some debug information
      Various updates to i.MX firmware drivers, mostly cosmetic
 
  - ARM SCMI/SCPI:
      A new mechanism for platform notifications is added, among a number
      of minor changes.
 
  - optee:
      Probing of the TEE bus is rewritten to better support detection of
      devices that depend on the tee-supplicant user space.
      A new firmware based trusted platform module (fTPM) driver is added
      based on OP-TEE
 
  - SoC attributes:
      A new driver is added to provide a generic soc_device for identifying
      a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
      by probing SoC family specific registers.
      The series also contains some cleanups to the common soc_device code.
 
 There are also a number of updates to SoC specific drivers,
 the main ones are:
 
  - Mediatek cmdq driver gains a few in-kernel interfaces
 
  - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
    support for additional SoC variants
 
  - The Qualcomm GENI core code gains interconnect path voting and
    performance level support, and integrating this into a number of
    device drivers.
 
  - A new driver for Samsung Exynos5800 voltage coupler for
 
  - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
    specific device drivers
 
  - Updates to the TI K3 Ring Accelerator driver

6ce076f415 ARM: SoC changes for v5.9
These are mostly cosmetic changes and minor bugfixes for the SoC
 specific code, across the 32-bit at91, mvebu, davinci, samsung, and
 omap platforms.
 
 The main notable changes are for the Samsung Exynos platform, which
 sees a rewrite of gpio handling and a change to restore and adds
 a workaround for a problem with cpuidle support.

   cgroup. Also extend BPF selftests with coverage, from YiFei Zhu.

5) Add BPF exception tables to ARM64 JIT in order to be able to JIT BPF_PROBE_MEM
   load instructions, from Jean-Philippe Brucker.

6) Follow-up fixes on BPF socket lookup in combination with reuseport group
   handling. Also add related BPF selftests, from Jakub Sitnicki.

7) Allow to use socket storage in BPF_PROG_TYPE_CGROUP_SOCK-typed programs for
   socket create/release as well as bind functions, from Stanislav Fomichev.

8) Fix an info leak in xsk_getsockopt() when retrieving XDP stats via old struct
   xdp_statistics, from Peilin Ye.

9) Fix PT_REGS_RC{,_CORE}() macros in libbpf for MIPS arch, from Jerry Crunchtime.

10) Extend BPF kernel test infra with skb->family and skb->{local,remote}_ip{4,6}
    fields and allow user space to specify skb->dev via ifindex, from Dmitry Yakunin.

11) Fix a bpftool segfault due to missing program type name and make it more robust
    to prevent them in future gaps, from Quentin Monnet.

12) Consolidate cgroup helper functions across selftests and fix a v6 localhost
    resolver issue, from John Fastabend.

5f402bb175 gpio: don't use same lockdep class for all devm_gpiochip_add_data users
Commit 959bc7b22b ("gpio: Automatically add lockdep keys") documents
in its commits message its intention to "create a unique class key for
each driver".

It does so by having gpiochip_add_data add in-place the definition of
two static lockdep classes for LOCKDEP use. That way, every caller of
the macro adds their gpiochip with unique lockdep classes.

There are many indirect callers of gpiochip_add_data, however, via
use of devm_gpiochip_add_data. devm_gpiochip_add_data has external
linkage and all its users will share the same lockdep classes, which
probably is not intended.

Fix this by replicating the gpio_chip_add_data statics-in-macro for
the devm_ version as well.

Fixes: 959bc7b22b ("gpio: Automatically add lockdep keys")

c0dfadfed8 The main change in this cycle was to add support for ZSTD-compressed
kernel and initrd images.
 
 ZSTD has a very fast decompressor, yet it compresses better than gzip.
