      Pull RCU updates from Paul McKenney:
      
       - Documentation updates, perhaps most notably Neil Brown's writeup of
         the reference-counting analogy to RCU.
      
       - Expedited grace-period cleanups.
      
       - Remove CONFIG_RCU_FAST_NO_HZ due to lack of valid users. I have asked
         around, posted a blog entry, and sent this series to LKML without
         result.
      
       - Miscellaneous fixes.
      
       - RCU callback offloading updates, perhaps most notably Frederic
         Weisbecker's updates allowing CPUs booted in the de-offloaded state
         to be offloaded at runtime.
      
       - nolibc fixes from Willy Tarreau and Anmar Faizi, but also including
         Mark Brown's addition of gettid().
      
       - RCU Tasks Trace fixes, including changes that increase the
         scalability of call_rcu_tasks_trace() for the BPF folks (Martin Lau
         and KP Singh).
      
       - Various fixes including those from Wander Lairson Costa and Li
         Zhijian.
      
       - Fixes plus addition of tests for the increased call_rcu_tasks_trace()
         scalability.

      Pull printk updates from Petr Mladek:
      
       - Remove some twists in the console registration code. It does not
         change the existing behavior except for one corner case. The proper
         default console (with tty binding) will be registered again even when
         it has been removed in the meantime. It is actually a bug fix.
         Anyway, this modified behavior requires some manual interaction.
      
       - Optimize gdb extension for huge ring buffers.

      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
         code in that the hooks are now more strictly synchronized and thus
         the interacting operations can become more straight-forward.
      
         Lai is in the process of simplifying workqueue code and this pull
         request contains some of the patches.

      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).
      
         - Allow model-specific normal EPB value to be used in the intel_epb
           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).
      
         - Reduce DTPM trace verbosity (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.

       "Core
        ----
      
         - 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
        ---
      
         - New helpers:
            - bpf_find_vma(), find and inspect VMAs for profiling use cases
            - bpf_loop(), runtime-bounded loop helper trading some execution
              time for much faster (if at all converging) verification
            - bpf_strncmp(), improve performance, avoid compiler flakiness
            - 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.
      
        Protocols
        ---------
      
         - WiFi (mac80211/cfg80211):
            - notify user space about long "come back in N" AP responses,

            - support fastclose option (quick shutdown of the full MPTCP
              connection, similar to TCP RST in regular TCP)
      
         - MCTP (Management Component Transport) over serial, as defined by
           DMTF spec DSP0253 - "MCTP Serial Transport Binding".

        ----------
      
         - Support timestamping on bond interfaces in active/passive mode.
      
         - Introduce generic phylink link mode validation for drivers which
           don't have any quirks and where MAC capability bits fully express
           what's supported. Allow PCS layer to participate in the validation.
           Convert a number of drivers.
      
         - Add support to set/get size of buffers on the Rx rings and size of
           the tx copybreak buffer via ethtool.
      
         - Support offloading TC actions as first-class citizens rather than
           only as attributes of filters, improve sharing and device resource
           utilization.

      This reverts commit a896f870.
      
      It causes odd flickering on my Radeon RX580 (PCI ID 1002:67df rev e7,
      subsystem ID 1da2:e353).
      
      Bisected right to this commit, and reverting it fixes things.

       - Separate struct slab from struct page - an offshot of the page folio
         work.
      
         Struct page fields used by slab allocators are moved from struct page
         to a new struct slab, that uses the same physical storage. Similar to
         struct folio, it always is a head page. This brings better type
         safety, separation of large kmalloc allocations from true slabs, and
         cleanup of related objcg code.

      Pull random number generator updates from Jason Donenfeld:
       "These a bit more numerous than usual for the RNG, due to folks
        resubmitting patches that had been pending prior and generally renewed
        interest.
      
        There are a few categories of patches in here:
      
         1) Dominik Brodowski and I traded a series back and forth for a some
            weeks that fixed numerous issues related to seeds being provided
            at extremely early boot by the firmware, before other parts of the
            kernel or of the RNG have been initialized, both fixing some
            crashes and addressing correctness around early boot randomness.
            One of these is marked for stable.
      
         2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
            extractor, and made the construction a bit safer and more
            standard. This was sort of a long overdue low hanging fruit, as we
            were supposed to have phased out SHA-1 usage quite some time ago
            (even if all we needed here was non-invertibility). Along the way
            it also made extraction 131% faster. This required a bit of
            Kconfig and symbol plumbing to make things work well with the
            crypto libraries, which is one of the reasons why I'm sending you
            this pull early in the cycle.
      
         3) I got rid of a truly superfluous call to RDRAND in the hot path,
            which resulted in a whopping 370% increase in performance.
      
         4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
            the full series of which wasn't ready yet, but the first two
            preparatory cleanups were good on their own. One of them touches
            files in kernel/irq/, which is the other reason why I'm sending
            you this pull early in the cycle.
      
         5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
            Mark Brown, Dominik Brodowski, and myself"
