      Pull x86 cpu-feature updates from Ingo Molnar:
       - Rework the Intel model names symbols/macros, which were decades of
         ad-hoc extensions and added random noise. It's now a coherent, easy
         to follow nomenclature.
       - Add new Intel CPU model IDs:
          - "Tiger Lake" desktop and mobile models
          - "Elkhart Lake" model ID
          - and the "Lightning Mountain" variant of Airmont, plus support code
       - Add the new AVX512_VP2INTERSECT instruction to cpufeatures
       - Remove Intel MPX user-visible APIs and the self-tests, because the
         toolchain (gcc) is not supporting it going forward. This is the
         first, lowest-risk phase of MPX removal.
       - Remove X86_FEATURE_MFENCE_RDTSC
       - Various smaller cleanups and fixes

       - MAINTAINERS: Add Mark Rutland as perf submaintainer, Juri Lelli and
         Vincent Guittot as scheduler submaintainers. Add Dietmar Eggemann,
         Steven Rostedt, Ben Segall and Mel Gorman as scheduler reviewers.
         As perf and the scheduler is getting bigger and more complex,
         document the status quo of current responsibilities and interests,
         and spread the review pain^H^H^H^H fun via an increase in the Cc:
         linecount generated by scripts/get_maintainer.pl. :-)
       - Add another series of patches that brings the -rt (PREEMPT_RT) tree
         closer to mainline: split the monolithic CONFIG_PREEMPT dependencies
         into a new CONFIG_PREEMPTION category that will allow the eventual
         introduction of CONFIG_PREEMPT_RT. Still a few more hundred patches
         to go though.
       - Extend the CPU cgroup controller with uclamp.min and uclamp.max to
         allow the finer shaping of CPU bandwidth usage.
       - Micro-optimize energy-aware wake-ups from O(CPUS^2) to O(CPUS).
       - Improve the behavior of high CPU count, high thread count
         applications running under cpu.cfs_quota_us constraints.
       - Improve balancing with SCHED_IDLE (SCHED_BATCH) tasks present.
       - Improve CPU isolation housekeeping CPU allocation NUMA locality.
       - Fix deadline scheduler bandwidth calculations and logic when cpusets
         rebuilds the topology, or when it gets deadline-throttled while it's
         being offlined.
       - Convert the cpuset_mutex to percpu_rwsem, to allow it to be used from
         setscheduler() system calls without creating global serialization.
         Add new synchronization between cpuset topology-changing events and
         the deadline acceptance tests in setscheduler(), which were broken
       - Rework the active_mm state machine to be less confusing and more
       - Rework (simplify) the pick_next_task() slowpath.
       - Improve load-balancing on AMD EPYC systems.
       - ... and misc cleanups, smaller fixes and improvements - please see
         the Git log for more details.

      Pull ARM DT updates from Arnd Bergmann:
       "This is another huge branch with close to 450 changessets related to
        devicetree files, roughly half of this for 32-bit and 64-bit
        respectively. There are lots of cleanups and additional hardware
        support for platforms we already support based on SoCs from Renesas,
        ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and
        other manufacturers.
        A total of 6 new SoCs and 37 new boards gets added this time, one more
        SoC will come in a follow-up branch. Most of the new boards are for
        64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
        Going more into details for SoC platforms with new hardware support:
         - The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone
           platform, usually paired with an external 5G modem. So far we only
           support the Qualcomm SM8150 MTP reference platform, but no actual
         - For the slightly older Qualcomm platforms, support for several
           interesting products is getting added: Three laptops based on
           Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix
           630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630)
           and several phones based on the older Snapdragon 410/MSM8916
           (Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed"
           aka Wileyfox Swift).
         - Mediatek MT7629 is a new wireless network router chip, similar to
           the older MT7623. It gets added together with the reference board
         - Allwinner V3 is a repackaged version of the existing low-end V3s
           chip, and is used in the tiny Lichee Pi Zero plus, also added here.
           There is also a new TV set-top box based on Allwinner H6, the Tanix
           TX6, and the eMMC variant of the Olimex A64-Olinuxino development
         - NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC
           family, similar to the i.MX8M Mini. As usual, there is a large
           number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML,
           SolidRun Hummingboard Pulse baseboard and System-on-Module,
           Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion
           PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the
           Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
           phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
           Innovations i.MX7 RMU2 board.
         - In a different NXP product line, the Layerscape LS1046A "Freeway"
           reference board gets added.
         - Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from
           their set-top-box line and smart speaker with newer CPU and GPU
           cores compared to their predecessors. Both are now also supported
           by the Khadas VIM3 development board series, and the dts files for
           that get reorganized a bit to better deal with all variants.
           Another board based on SM1 that gets added is the SEI Robotics
         - There are a handful of new x86 and Power9 server boards using
           Aspeed BMC chips that are gaining support for running Linux on the
           BMC through the OpenBMC project: Facebook
           Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably
           these are still new machines using SoCs based on the ARM9 and ARM11
           CPU cores, as support for the new Cortex-A7 based AST2600 is still
           ramping up.
         - There are three new end-user products using 32-bit Rockchips SoCs:
           Mecer Xtreme Mini S6 is an Android "mini PC" box based on the
           low-end RK3229 chip, while the two AOpen products Chromebox Mini
           (Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for
           commercial settings(digital signage, PoS, ...).
         - One more single-board computer based on the popular 64-bit RK3399
           is added: the Leez RK3399 P710"

      Pull ARM SoC platform updates from Arnd Bergmann:
       "The main change this time around is a cleanup of some of the oldest
        platforms based on the XScale and ARM9 CPU cores, which are between 10
        and 20 years old.
        The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
        IOP33x/IOP13xx platforms are removed after we determined that nobody
        is using them any more.
        The TI Davinci and NXP LPC32xx platforms on the other hand are still
        in active use and are converted to the ARCH_MULTIPLATFORM build,
        meaning that we can compile a kernel that works on these along with
        most other ARMv5 platforms. Changes toward that goal are also merged
        for IOP32x, but additional work is needed to complete this. Patches
        for the remaining ARMv5 platforms have started but need more work and
        some testing.
        Support for the new ASpeed AST2600 gets added, this is based on the
        Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
        ARMv6 chips in the same family.
        Other changes include a cleanup of the ST-Ericsson ux500 platform and
        the move of the TI Davinci platform to a new clocksource driver"
      [ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
        buildable on other platforms through COMPILE_TEST, but that causes new
        warnings that I most definitely do not want to see during the merge
        window as that could hide other issues.
        So the COMPILE_TEST option got disabled for them again   - Linus ]

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of changes in the GPIO subsystem for the v5.4 kernel
        Core changes:
         - Support hierarchical GPIO irqchips.
           We now have three consumers that can use this: Intel IXP4xx,
           ThunderX and Qualcomm SPMI GPIO (in the pinctrl subsystem).
           The support code has been long in the making and hashed out so it
           should be easily adaptable for all hierarchical irqchip parents.
           The code only gets compiled in if hierarchical irqchip is used at
           the topmost irq controller at least, as the hierarchical irqchip
           requires strict hierarchy all the way up in the system.
         - Determine the need for a "valid_mask" for GPIO lines on the
           gpio_chip and conversely for the "valid_mask" for the GPIO
           interrupt chip interrupt lines by looking for a .init_valid_mask()
           callback in the main chip or GPIO interrupt chip respectively.
           Allocate it with bitmap_alloc().
         - Isolate the device tree/open firmware GPIO description code out in
           its own file properly.
         - Isolate the ACPI GPIO description code out in its own file
         - Drop a whole lot of #ifdef:s in the main includes: it does not hurt
           to keep the include items around, and we get quicker and clearer
           compile failures if the appropriate kernel symbols are not selected
           for drivers.
        New/deleted drivers:
         - New driver for Aspeed SGPIO.
         - The KS8695 driver is deleted as the platform gets deleted from
           arch/arm in this kernel cycle.
         - The Cirrus Logic Madera driver now supports CS47L92 and CS47L15.
         - The Freescale MPC8xxx now supports LS1028A and LS1088A.
        Driver improvements:
         - We pass the GPIO irqchip intialization by directly filling in the
           struct instead of using set-up functions (the new way) for Intel
           MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86,
           MT7621, Zynq and EP93xx.
        Out-of-band changes:
         - Fix a GPIO header inclusion in Unicore - no response from
         - Drop FMC subsystem from MAINTAINERS - was deleted in the GPIO tree
           last cycle so let's mop up the shards"

       "This contains two features and various tests.
        First, it adds support for waiting on process through pidfds by adding
        the P_PIDFD type to the waitid() syscall. This completes the basic
        functionality of the pidfd api (cf. [1]). In the meantime we also have
        a new adition to the userspace projects that make use of the pidfd
        api. The qt project was nice enough to send a mail pointing out that
        they have a pr up to switch to the pidfd api (cf. [2]).
        Second, this tag contains an extension to the waitid() syscall to make
        it possible to wait on the current process group in a race free manner
        (even though the actual problem is very unlikely) by specifing 0
        together with the P_PGID type. This extension traces back to a
        discussion on the glibc development mailing list.
        There are also a range of tests for the features above. Additionally,
        the test-suite which detected the pidfd-polling race we fixed in [3]

      Revert "ext4: make __ext4_get_inode_loc plug" · 72dbcf72
      Linus Torvalds authored
      This reverts commit b03755ad.
      This is sad, and done for all the wrong reasons.  Because that commit is
      good, and does exactly what it says: avoids a lot of small disk requests
      for the inode table read-ahead.
      However, it turns out that it causes an entirely unrelated problem: the
      getrandom() system call was introduced back in 2014 by commit
       ("random: introduce getrandom(2) system call"), and people
      use it as a convenient source of good random numbers.
      But part of the current semantics for getrandom() is that it waits for
      the entropy pool to fill at least partially (unlike /dev/urandom).  And
      at least ArchLinux apparently has a systemd that uses getrandom() at
      boot time, and the improvements in IO patterns means that existing
      installations suddenly start hanging, waiting for entropy that will
      never happen.
      It seems to be an unlucky combination of not _quite_ enough entropy,
      together with a particular systemd version and configuration.  Lennart
      says that the systemd-random-seed process (which is what does this early
      access) is supposed to not block any other boot activity, but sadly that
      doesn't actually seem to be the case (possibly due bogus dependencies on
      cryptsetup for encrypted swapspace).
      The correct fix is to fix getrandom() to not block when it's not
      appropriate, but that fix is going to take a lot more discussion.  Do we
      just make it act like /dev/urandom by default, and add a new flag for
      "wait for entropy"? Do we add a boot-time option? Or do we just limit
      the amount of time it will wait for entropy?
      So in the meantime, we do the revert to give us time to discuss the
      eventual fix for the fundamental problem, at which point we can re-apply
      the ext4 inode table access optimization.
