      Pull erofs updates from Gao Xiang:
       "In this cycle, tail-packing data inline for compressed files is now
        supported so that tail pcluster can be stored and read together with
        inode metadata in order to save data I/O and storage space.
      
        In addition to that, to prepare for the upcoming subpage, folio and
        fscache features, we also introduce meta buffers to get rid of
        erofs_get_meta_page() since it was too close to the page itself.
      
        In addition, in order to show supported kernel features and control
        sync decompression strategy, new sysfs nodes are introduced in this
        cycle as well.
      
        Summary:
      
         - add sysfs interface and a sysfs node to control sync decompression
      
         - add tail-packing inline support for compressed files
      
         - get rid of erofs_get_meta_page()"

      drivers/pcmcia: Fix ifdef covering yenta_pm_ops · 579f3a6d
      Paul E. McKenney authored
      Currently, yenta_dev_suspend_noirq(), yenta_dev_resume_noirq(), and
      yenta_pm_ops are covered by "#ifdef CONFIG_PM", which results in
      compiler warnings in kernels built with CONFIG_PM_SLEEP=n and
      CONFIG_PM=y:
      
        drivers/pcmcia/yenta_socket.c:1322:12: warning: ‘yenta_dev_resume_noirq’ defined but not used [-Wunused-function]
         1322 | static int yenta_dev_resume_noirq(struct device *dev)

      This affects kernels built without suspend and hibernation.
      
      Avoid these warnings by using "#ifdef CONFIG_PM_SLEEP".

      Linus Torvalds authored
      Pull fs idmapping updates from Christian Brauner:
       "This contains the work to enable the idmapping infrastructure to
        support idmapped mounts of filesystems mounted with an idmapping.
      
        In addition this contains various cleanups that avoid repeated
        open-coding of the same functionality and simplify the code in quite a
        few places.
      
        We also finish the renaming of the mapping helpers we started a few
        kernel releases back and move them to a dedicated header to not
        continue polluting the fs header needlessly with low-level idmapping
        helpers. With this series the fs header only contains idmapping
        helpers that interact with fs objects.
      
        Currently we only support idmapped mounts for filesystems mounted
        without an idmapping themselves. This was a conscious decision
        mentioned in multiple places (cf. [1]).
      
        As explained at length in [3] it is perfectly fine to extend support
        for idmapped mounts to filesystem's mounted with an idmapping should
        the need arise. The need has been there for some time now (cf. [2]).
      
        Before we can port any filesystem that is mountable with an idmapping
        to support idmapped mounts in the coming cycles, we need to first
        extend the mapping helpers to account for the filesystem's idmapping.
        This again, is explained at length in our documentation at [3] and
        also in the individual commit messages so here's an overview.
      
        Currently, the low-level mapping helpers implement the remapping
        algorithms described in [3] in a simplified manner as we could rely on
        the fact that all filesystems supporting idmapped mounts are mounted
        without an idmapping.
      
        In contrast, filesystems mounted with an idmapping are very likely to
        not use an identity mapping and will instead use a non-identity
        mapping. So the translation step from or into the filesystem's
        idmapping in the remapping algorithm cannot be skipped for such
        filesystems.
      
        Non-idmapped filesystems and filesystems not supporting idmapped
        mounts are unaffected by this change as the remapping algorithms can
        take the same shortcut as before. If the low-level helpers detect that
        they are dealing with an idmapped mount but the underlying filesystem
        is mounted without an idmapping we can rely on the previous shortcut
        and can continue to skip the translation step from or into the
        filesystem's idmapping. And of course, if the low-level helpers detect
        that they are not dealing with an idmapped mount they can simply
        return the relevant id unchanged; no remapping needs to be performed
        at all.
      
        These checks guarantee that only the minimal amount of work is
        performed. As before, if idmapped mounts aren't used the low-level
        helpers are idempotent and no work is performed at all"

       "The gpio-sim module is back, this time without any changes to

        never got any follow-up on the committable items and didn't want to
        delay this module for several more months.
      
        Other than that we have support for several new models and some
        support going away. We started working on converting GPIO drivers to
        using fwnode exclusively in order to limit references to OF symbols to
        gpiolib-of.c exclusively. We also have regular tweaks and improvements
        all over the place.
      
        Summary:
      
         - new testing module: gpio-sim that is scheduled to replace
           gpio-mockup
      
         - initial changes aiming at converting all GPIO drivers to using the
           fwnode interface and limiting any references to OF symbols to
           gpiolib-of.c
      
         - add support for Tegra234 and Tegra241 to gpio-tegra186

         - drop support for unused platforms in gpio-xlp
      
         - cleanup leftovers from the removal of the legacy Samsung Exynos
           GPIO driver
      
         - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make
           PREEMPT_RT happy
      
         - generalize the common 'ngpios' device property by reading it in the
           core gpiolib code so that we can remove duplicate reads from
           drivers
      
         - allow line names from device properties to override names set by
           drivers
      
         - code shrink in gpiod_add_lookup_table()

      Pull workqueue updates from Tejun Heo:
      
       - The code around workqueue scheduler hooks got reorganized early 2019
         which unfortuately introdued a couple subtle and rare race conditions
         where preemption can mangle internal workqueue state triggering a
         WARN and possibly causing a stall or at least delay in execution.
      
         Frederic fixed both early December and the fixes were sitting in
         for-5.16-fixes which I forgot to push. They are here now. I'll
         forward them to stable after they land.
      
       - The scheduler hook reorganization has more implicatoins for workqueue

      select: Fix indefinitely sleeping task in poll_schedule_timeout() · 68514dac
      Jan Kara authored
      A task can end up indefinitely sleeping in do_select() ->
      poll_schedule_timeout() when the following race happens:
      
        TASK1 (thread1)             TASK2                   TASK1 (thread2)
        do_select()
          setup poll_wqueues table
          with 'fd'
                                    write data to 'fd'
                                      pollwake()
                                        table->triggered = 1
                                                            closes 'fd' thread1 is
                                                              waiting for
          poll_schedule_timeout()
            - sees table->triggered
            table->triggered = 0
            return -EINTR
          loop back in do_select()
      
      But at this point when TASK1 loops back, the fdget() in the setup of
      poll_wqueues fails.  So now so we never find 'fd' is ready for reading
      and sleep in poll_schedule_timeout() indefinitely.
      
      Treat an fd that got closed as a fd on which some event happened.  This
      makes sure cannot block indefinitely in do_select().
      
      Another option would be to return -EBADF in this case but that has a
      potential of subtly breaking applications that excercise this behavior
      and it happens to work for them.  So returning fd as active seems like a
      safer choice.

      Pull power management updates from Rafael Wysocki:
       "The most signigicant change here is the addition of a new cpufreq
        'P-state' driver for AMD processors as a better replacement for the
        venerable acpi-cpufreq driver.
      
        There are also other cpufreq updates (in the core, intel_pstate, ARM
        drivers), PM core updates (mostly related to adding new macros for
        declaring PM operations which should make the lives of driver
        developers somewhat easier), and a bunch of assorted fixes and
        cleanups.
      
        Summary:
      
         - Add new P-state driver for AMD processors (Huang Rui).
      
         - Fix initialization of min and max frequency QoS requests in the
           cpufreq core (Rafael Wysocki).
      
         - Fix EPP handling on Alder Lake in intel_pstate (Srinivas
           Pandruvada).
      
         - Make intel_pstate update cpuinfo.max_freq when notified of HWP
           capabilities changes and drop a redundant function call from that
           driver (Rafael Wysocki).
      
         - Improve IRQ support in the Qcom cpufreq driver (Ard Biesheuvel,
           Stephen Boyd, Vladimir Zapolskiy).
      
         - Fix double devm_remap() in the Mediatek cpufreq driver (Hector
           Yuan).
      
         - Introduce thermal pressure helpers for cpufreq CPU cooling (Lukasz
           Luba).
      
         - Make cpufreq use default_groups in kobj_type (Greg Kroah-Hartman).
      
         - Make cpuidle use default_groups in kobj_type (Greg Kroah-Hartman).
      
         - Fix two comments in cpuidle code (Jason Wang, Yang Li).

           sysfs attribute handling code (Srinivas Pandruvada).
      
         - Simplify locking in pm_runtime_put_suppliers() (Rafael Wysocki).
      
         - Add safety net to supplier device release in the runtime PM core
           code (Rafael Wysocki).
      
         - Capture device status before disabling runtime PM for it (Rafael
           Wysocki).
      
         - Add new macros for declaring PM operations to allow drivers to
           avoid guarding them with CONFIG_PM #ifdefs or __maybe_unused and
           update some drivers to use these macros (Paul Cercueil).
      
         - Allow ACPI hardware signature to be honoured during restore from
           hibernation (David Woodhouse).
      
         - Update outdated operating performance points (OPP) documentation
           (Tang Yizhou).
      
         - Reduce log severity for informative message regarding frequency
           transition failures in devfreq (Tzung-Bi Shih).
      
         - Add DRAM frequency controller devfreq driver for Allwinner sunXi
           SoCs (Samuel Holland).
      
         - Add missing COMMON_CLK dependency to sun8i devfreq driver (Arnd
           Bergmann).
      
         - Add support for new layout of Psys PowerLimit Register on SPR to
           the Intel RAPL power capping driver (Zhang Rui).
      
         - Fix typo in a comment in idle_inject.c (Jason Wang).
      
         - Remove unused function definition from the DTPM (Dynamit Thermal
           Power Management) power capping framework (Daniel Lezcano).

      netfilter: nf_tables: don't use 'data_size' uninitialized · 63045bfd
      Linus Torvalds authored
      Commit 2c865a8a ("netfilter: nf_tables: add rule blob layout") never
      initialized the new 'data_size' variable.
      
      I'm not sure how it ever worked, but it might have worked almost by
      accident - gcc seems to occasionally miss these kinds of 'variable used
      uninitialized' situations, but I've seen it do so because it ended up
      zero-initializing them due to some other simplification.
      
      But clang is very unhappy about it all, and correctly reports
      
          net/netfilter/nf_tables_api.c:8278:4: error: variable 'data_size' is uninitialized when used here [-Werror,-Wuninitialized]
                                  data_size += sizeof(*prule) + rule->dlen;
                                  ^~~~~~~~~
          net/netfilter/nf_tables_api.c:8263:30: note: initialize the variable 'data_size' to silence this warning
                  unsigned int size, data_size;
                                              ^
                                               = 0
          1 error generated.
      
      and this fix just initializes 'data_size' to zero before the loop.

        ----
      
         - Defer freeing TCP skbs to the BH handler, whenever possible, or at
           least perform the freeing outside of the socket lock section to
           decrease cross-CPU allocator work and improve latency.
      
         - Add netdevice refcount tracking to locate sources of netdevice and
           net namespace refcount leaks.
      
         - Make Tx watchdog less intrusive - avoid pausing Tx and restarting
           all queues from a single CPU removing latency spikes.
      
         - Various small optimizations throughout the stack from Eric Dumazet.
      
         - Make netdev->dev_addr[] constant, force modifications to go via
           appropriate helpers to allow us to keep addresses in ordered data
           structures.
      
         - Replace unix_table_lock with per-hash locks, improving performance
           of bind() calls.
      
         - Extend skb drop tracepoint with a drop reason.
      
         - Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.

            - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
              for tracing programs, all inlined by the verifier
      
         - Support BPF relocations (CO-RE) in the kernel loader.
      
         - Further the support for BTF_TYPE_TAG annotations.
      
         - Allow access to local storage in sleepable helpers.
      
         - Convert verifier argument types to a composable form with different
           attributes which can be shared across types (ro, maybe-null).
      
         - Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
           creating new, extensible ones where missing and deprecating those
           to be removed.
