      This reverts commit 6bf950a8.
      
      To align with other vendors, NET_VENDOR configs are supposed to be ON by
      default, while their drivers should default to OFF.

      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.

       - 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.

      Linus Torvalds authored
      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"
