      Pull cgroup updates from Tejun Heo:
       "Several core optimizations:
      
         - threadgroup_rwsem write locking is skipped when configuring
           controllers in empty subtrees.
      
           Combined with CLONE_INTO_CGROUP, this allows the common static
           usage pattern to not grab threadgroup_rwsem at all (glibc still
           doesn't seem ready for CLONE_INTO_CGROUP unfortunately).
      
         - threadgroup_rwsem used to be put into non-percpu mode by default
           due to latency concerns in specific use cases. There's no reason
           for everyone else to pay for it. Make the behavior optional.
      
         - psi no longer allocates memory when disabled.

         - Add a new taint type, TAINT_TEST to signal that a test has been
           run.
      
           This should discourage people from running these tests on
           production systems, and to make it easier to tell if tests have

      Pull RCU updates from Paul McKenney:
      
       - Documentation updates
      
       - Miscellaneous fixes
      
       - Callback-offload updates, perhaps most notably a new
         RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to be
         offloaded at boot time, regardless of kernel boot parameters.
      
         This is useful to battery-powered systems such as ChromeOS and
         Android. In addition, a new RCU_NOCB_CPU_CB_BOOST kernel boot
         parameter prevents offloaded callbacks from interfering with
         real-time workloads and with energy-efficiency mechanisms
      
       - Polled grace-period updates, perhaps most notably making these APIs
         account for both normal and expedited grace periods
      
       - Tasks RCU updates, perhaps most notably reducing the CPU overhead of
         RCU tasks trace grace periods by more than a factor of two on a
         system with 15,000 tasks.
      
         The reduction is expected to increase with the number of tasks, so it
         seems reasonable to hypothesize that a system with 150,000 tasks
         might see a 20-fold reduction in CPU overhead
      
       - Torture-test updates
      
       - Updates that merge RCU's dyntick-idle tracking into context tracking,
         thus reducing the overhead of transitioning to kernel mode from
         either idle or nohz_full userspace execution for kernels that track
         context independently of RCU.
      
         This is expected to be helpful primarily for kernels built with
         CONFIG_NO_HZ_FULL=y

        this last cycle, not all of it is coming through this tree, as this
        cycle saw a shift toward tackling early boot time seeding issues,
        which took place in other trees as well.
      
        Here's a summary of the various patches:
      
         - The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot
           option have been removed, as they overlapped with the more widely
           supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and
           "random.trust_cpu". This change allowed simplifying a bit of arch
           code.
      
         - x86's RDRAND boot time test has been made a bit more robust, with
           RDRAND disabled if it's clearly producing bogus results. This would
           be a tip.git commit, technically, but I took it through random.git
           to avoid a large merge conflict.
      
         - The RNG has long since mixed in a timestamp very early in boot, on
           the premise that a computer that does the same things, but does so
           starting at different points in wall time, could be made to still
           produce a different RNG state. Unfortunately, the clock isn't set
           early in boot on all systems, so now we mix in that timestamp when
           the time is actually set.
      
         - User Mode Linux now uses the host OS's getrandom() syscall to
           generate a bootloader RNG seed and later on treats getrandom() as
           the platform's RDRAND-like faculty.
      
         - The arch_get_random_{seed_,}_long() family of functions is now
           arch_get_random_{seed_,}_longs(), which enables certain platforms,
           such as s390, to exploit considerable performance advantages from
           requesting multiple CPU random numbers at once, while at the same
           time compiling down to the same code as before on platforms like
           x86.
      
         - A small cleanup changing a cmpxchg() into a try_cmpxchg(), from
           Uros.
      
         - A comment spelling fix"

       - Improve DM core's BLK_STS_DM_REQUEUE and BLK_STS_AGAIN handling.
      
       - Optimize DM core's more common bio splitting by eliminating the use
         of bio cloning with bio_split+bio_chain. Shift that cloning cost to
         the relatively unlikely dm_io requeue case that only occurs during
         error handling. Introduces dm_io_rewind() that will clone a bio that

      Pull io_uring buffered writes support from Jens Axboe:
       "This contains support for buffered writes, specifically for XFS. btrfs
        is in progress, will be coming in the next release.
      
        io_uring does support buffered writes on any file type, but since the
        buffered write path just always -EAGAIN (or -EOPNOTSUPP) any attempt
        to do so if IOCB_NOWAIT is set, any buffered write will effectively be
        handled by io-wq offload. This isn't very efficient, and we even have
        specific code in io-wq to serialize buffered writes to the same inode
        to avoid further inefficiencies with thread offload.
      
        This is particularly sad since most buffered writes don't block, they
        simply copy data to a page and dirty it. With this pull request, we
        can handle buffered writes a lot more effiently.
      
        If balance_dirty_pages() needs to block, we back off on writes as
        indicated.
      
        This improves buffered write support by 2-3x.
      
        Jan Kara helped with the mm bits for this, and Stefan handled the
        fs/iomap/xfs/io_uring parts of it"

      Pull io_uring updates from Jens Axboe:
      
       - As per (valid) complaint in the last merge window, fs/io_uring.c has
         grown quite large these days. io_uring isn't really tied to fs
         either, as it supports a wide variety of functionality outside of
         that.
      
         Move the code to io_uring/ and split it into files that either
         implement a specific request type, and split some code into helpers
         as well. The code is organized a lot better like this, and io_uring.c
         is now < 4K LOC (me).
      
       - Deprecate the epoll_ctl opcode. It'll still work, just trigger a
         warning once if used. If we don't get any complaints on this, and I
         don't expect any, then we can fully remove it in a future release
         (me).
      
       - Improve the cancel hash locking (Hao)
      
       - kbuf cleanups (Hao)
      
       - Efficiency improvements to the task_work handling (Dylan, Pavel)
      
       - Provided buffer improvements (Dylan)
      
       - Add support for recv/recvmsg multishot support. This is similar to
         the accept (or poll) support for have for multishot, where a single
         SQE can trigger everytime data is received. For applications that
         expect to do more than a few receives on an instantiated socket, this
         greatly improves efficiency (Dylan).
      
       - Efficiency improvements for poll handling (Pavel)
      
       - Poll cancelation improvements (Pavel)
      
       - Allow specifiying a range for direct descriptor allocations (Pavel)

       - Move io_uring types to greatly cleanup the tracing (Pavel)
      
       - Tons of great code cleanups and improvements (Pavel)
      
       - Add a way to do sync cancelations rather than through the sqe -> cqe
         interface, as that's a lot easier to use for some use cases (me).
      
       - Add support to IORING_OP_MSG_RING for sending direct descriptors to a
         different ring. This avoids the usually problematic SCM case, as we
         disallow those. (me)
      
       - Make the per-command alloc cache we use for apoll generic, place
         limits on it, and use it for netmsg as well (me).

        core, improve the cpufreq/devfreq cooling device handling, update some
        thermal control drivers and the tmon utility and clean up code.
      
        Specifics:
      
         - Consolidate the thermal core code by beginning to move the thermal
           trip structure from the thermal OF code as a generic structure to
           be used by the different sensors when registering a thermal zone

           (Krzysztof Kozlowski).
      
         - Remove the pointless get_trend() function in the QCom, Ux500 and

           macros (Daniel Lezcano).

           ida_simple_get()/ida_simple_remove() that have been deprecated
           (keliu).

        Some existing drivers get improvements and broader chip support and a
        new driver is added that emulates a PWM controller using a clock

       "The big update this time around is some excellent work from David

        meaning that we are seeing a huge reduction in the time spent between
        transfers for single threaded clients.
      
        Benchmarking has been coming out at about a halving of overhead which
        is clearly visible in system level usage that stresses SPI like some
        CAN and IIO applications, especially with small transfers. Thanks to
        David for taking the time to drill down into this and push the work
        upstream.
      
        Otherwise there's been a bunch of new device support and the usual
        updates.
