Pull thread updates from Christian Brauner:
 "This contains the changes to add the missing support for attaching to
  time namespaces via pidfds.

  Last cycle setns() was changed to support attaching to multiple
  namespaces atomically. This requires all namespaces to have a point of
  no return where they can't fail anymore.

  Specifically, <namespace-type>_install() is allowed to perform
  permission checks and install the namespace into the new struct nsset
  that it has been given but it is not allowed to make visible changes
  to the affected task. Once <namespace-type>_install() returns,
  anything that the given namespace type additionally requires to be
  setup needs to ideally be done in a function that can't fail or if it
  fails the failure must be non-fatal.

  For time namespaces the relevant functions that fell into this
  category were timens_set_vvar_page() and vdso_join_timens(). The
  latter could still fail although it didn't need to. This function is
  only implemented for vdso_join_timens() in current mainline. As
  discussed on-list (cf. [1]), in order to make setns() support time
  namespaces when attaching to multiple namespaces at once properly we
  changed vdso_join_timens() to always succeed. So vdso_join_timens()
  replaces the mmap_write_lock_killable() with mmap_read_lock().

  Please note that arm is about to grow vdso support for time namespaces
  (possibly this merge window). We've synced on this change and arm64
  also uses mmap_read_lock(), i.e. makes vdso_join_timens() a function
  that can't fail. Once the changes here and the arm64 changes have
  landed, vdso_join_timens() should be turned into a void function so
  it's obvious to callers and implementers on other architectures that
  the expectation is that it can't fail.

  We didn't do this right away because it would've introduced
  unnecessary merge conflicts between the two trees for no major gain.

  As always, tests included"

Pull execve updates from Eric Biederman:
 "During the development of v5.7 I ran into bugs and quality of
  implementation issues related to exec that could not be easily fixed
  because of the way exec is implemented. So I have been diggin into
  exec and cleaning up what I can.

  This cycle I have been looking at different ideas and different
  implementations to see what is possible to improve exec, and cleaning
  the way exec interfaces with in kernel users. Only cleaning up the
  interfaces of exec with rest of the kernel has managed to stabalize
  and make it through review in time for v5.9-rc1 resulting in 2 sets of
  changes this cycle.

   - Implement kernel_execve

   - Make the user mode driver code a better citizen

  With kernel_execve the code size got a little larger as the copying of
  parameters from userspace and copying of parameters from userspace is
  now separate. The good news is kernel threads no longer need to play
  games with set_fs to use exec. Which when combined with the rest of
  Christophs set_fs changes should security bugs with set_fs much more
  difficult"

The addition of percpu.h to the list of includes in random.h revealed
some circular dependencies on arm64 and possibly other platforms.  This
include was added solely for the pseudo-random definitions, which have
nothing to do with the rest of the definitions in this file but are
still there for legacy reasons.

This patch moves the pseudo-random parts to linux/prandom.h and the
percpu.h include with it, which is now guarded by _LINUX_PRANDOM_H and
protected against recursive inclusion.

A further cleanup step would be to remove this from <linux/random.h>
entirely, and make people who use the prandom infrastructure include
just the new header file.  That's a bit of a churn patch, but grepping
for "prandom_" and "next_pseudo_random32" "struct rnd_state" should
catch most users.

But it turns out that that nice cleanup step is fairly painful, because
a _lot_ of code currently seems to depend on the implicit include of
<linux/random.h>, which can currently come in a lot of ways, including
such fairly core headfers as <linux/net.h>.

So the "nice cleanup" part may or may never happen.

Pull ACPI updates from Rafael Wysocki:
 "These eliminate significant AML processing overhead related to using
  operation regions in system memory, update the ACPICA code in the
  kernel to upstream revision 20200717 (including a fix to prevent
  operation region reference counts from overflowing in some cases),
  remove the last bits of the (long deprecated) ACPI procfs interface
  and do some assorted cleanups.

  Specifics:

   - Eliminate significant AML processing overhead related to using
     operation regions in system memory by reworking the management of
     memory mappings in the ACPI code to defer unmap operations (to do
     them outside of the ACPICA locks, among other things) and making
     the memory operation reagion handler avoid releasing memory
     mappings created by it too early (Rafael Wysocki).

   - Avoid redundant object evaluation in the ACPI device properties
     handling code (Heikki Krogerus).

   - Avoid unecessary memory overhead related to storing the signatures
     of the ACPI tables recognized by the kernel (Ard Biesheuvel).

   - Add missing newline characters when printing module parameter
     values in some places (Xiongfeng Wang).

   - Update the link to the ACPI specifications in some places (Tiezhu
     Yang).

   - Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R.

   - Drop redundant variable initialization from the APEI code (Colin

 "The most significant change here is the extension of the Energy Model
  to cover non-CPU devices (as well as CPUs) from Lukasz Luba.

  There is also some new hardware support (Ice Lake server idle states

  done by Lee Jones.

  Specifics:

   - Make the Energy Model cover non-CPU devices (Lukasz Luba).

       * Add a new sysfs attribute for disabling/enabling CPU
         energy-efficiency optimizations in the processor.

       * Make the driver avoid enabling HWP if EPP is not supported.

       * Allow the driver to handle numeric EPP values in the sysfs
         interface and fix the setting of EPP via sysfs in the active

Pull new ARM SoC support from Arnd Bergmann:
 "There are three SoC families newly dded to the 32-bit and 64-bit Arm
  architecture code in the kernel this time:

   - Daniel Palmer adds initial support for two chips made by MStar, a
     taiwanese SoC manufacturer that became part of Mediatek in 2012.

     For now, the added support is fairly minimal, with just two of its
     Cortex-A7 based 32-bit camera chips getting support for a limited
     set of on-chip peripherals.

   - Lars Povlsen from Microchip adds support for their new Sparx5
     family of ethernet switch chips using 64-bit Cortex-A53 cores.

     These are descended from earlier VSC7xxx SparX and Ocelot chips
     using 32-bit MIPS cores.

   - Daniele Alessandrelli from Intel adds support for the new Keem Bay
     SoC for computer vision, built around a Movidius VPU with Linux
     running on Arm Cortex-A53 cores"

Pull ARM SoC driver updates from Arnd Bergmann:
 "A couple of subsystems have their own subsystem maintainers but choose
  to have the code merged through the soc tree as upstream, as the code
  tends to be used across multiple SoCs or has SoC specific drivers
  itself:

   - memory controllers:

     Krzysztof Kozlowski takes ownership of the drivers/memory subsystem
     and its drivers, starting out with a set of cleanup patches.

     A larger driver for the Tegra memory controller that was
     accidentally missed for v5.8 is now added.

   - reset controllers:

     Only minor updates to drivers/reset this time

   - firmware:

     The "turris mox" firmware driver gains support for signed firmware
     blobs The tegra firmware driver gets extended to export some debug
     information Various updates to i.MX firmware drivers, mostly
     cosmetic

   - ARM SCMI/SCPI:

     A new mechanism for platform notifications is added, among a number
     of minor changes.

   - optee:

     Probing of the TEE bus is rewritten to better support detection of
     devices that depend on the tee-supplicant user space. A new
     firmware based trusted platform module (fTPM) driver is added based
     on OP-TEE

   - SoC attributes:

     A new driver is added to provide a generic soc_device for
     identifying a machine through the SMCCC ARCH_SOC_ID firmware
     interface rather than by probing SoC family specific registers.

     The series also contains some cleanups to the common soc_device
     code.

  There are also a number of updates to SoC specific drivers, the main
  ones are:

   - Mediatek cmdq driver gains a few in-kernel interfaces

   - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
     support for additional SoC variants

   - The Qualcomm GENI core code gains interconnect path voting and
     performance level support, and integrating this into a number of
     device drivers.

   - A new driver for Samsung Exynos5800 voltage coupler for

   - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
     specific device drivers

   - Updates to the TI K3 Ring Accelerator driver"

Pull ARM SoC DT updates from Arnd Bergmann:
 "As usual, there are many patches addressing minor issues in existing
  DTS files, such as DTC warnings, or adding support for additional
  peripherals.

  There are three added SoCs in existing product families:

   - Amazon:

     Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs,
     otherwise known as AL73400 or first-generation Graviton, and
     following the already supported Cortex-A1`5 and Cortex-A57 based
     Alpine chips. This one is added together with the official
     Evaluation platform.

   - Qualcomm:

     The Snapdragon SDM630 platform is a family of mid-range mobile
     phone chips from 2017 based on Cortex-A53 or Kryo 260 CPUs. A total
     of five end-user products are added based on these, all Android
     phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra.

   - Renesas:

     RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G
     family, and apparently closely related to the RZ/G2N and RZ/G2M
     models we already support but has a faster GPU and additional
     on-chip peripherals. It is added along with the HopeRun HiHope
     RZ/G2H development board

  A small number of new boards for already supported SoCs also debut:

   - Allwinner sunxi:

     Only one new machine, revision v1.2 of the Pine64 PinePhone
     (non-Android) smartphone, containing minor changes compared to
     earlier versions.

   - Amlogic Meson:

     WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box

   - Aspeed:

     EthanolX is AMD's EPYC data center rerence platform, using an
     ASpeed AST2600 baseboard management controller.

   - Mediatek:

     Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook based
     on the MT8183 (Helio P60t) SoC.

   - Nvidia Tegra:

     ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android
     tablets from around 2012 using Tegra 3 and Tegra 2, respectively.
     Thanks to PostmarketOS, these can now run mainline kernels and
     become useful again.

     The Jetson Xavier NX Developer Kit uses a SoM and carrier board for
     the Tegra194, their latest 64-bit chip based on Carmel CPU cores
     and Volta graphics.

   - NXP i.MX:

     Five new boards based on the 32-bit i.MX6 series are added: The
     MYiR MYS-6ULX single-board computer, and four different models of
     industrial computers from Protonic.

   - Qualcomm:

     MikroTik RouterBoard 3011 is a rackmounted router based on the
     32-bit IPQ8064 networking SoC

     Three older phones get added, the Snapdragon 808 (msm8992) based
     Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running
     Windows Phone, and the Snapdragon 810 (msm8994) based Sony Xperia
     Z5.

   - Renesas:

     In addition to the HiHope RZ/G2H board mentioned above, we gain
     support for board versions 3.0 and 4.0 of the earlier RZ/G2M and
     RZ/G2N reference boards. Beacon EmbeddedWorks adds another
     SoM+Carrier development board for RZ/G2M.

   - Rockchips:

     Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it is
     based on, using the high-end 32-bit rk3288 SoC.

  Notable updates to existing platforms are usually for added on-chip
  peripherals, including:

   - ASpeed AST2xxx (various)

   - Allwinner (cpufreq, thermal, Pinephone touchscreen)

   - Amlogic Meson (audio, gpu dvdfs, board updates)

  x86/alternatives: Add pr_fmt() to debug macros

Pull scheduler updates from Ingo Molnar:

 - Improve uclamp performance by using a static key for the fast path

 - Add the "sched_util_clamp_min_rt_default" sysctl, to optimize for
   better power efficiency of RT tasks on battery powered devices.
   (The default is to maximize performance & reduce RT latencies.)

 - Improve utime and stime tracking accuracy, which had a fixed boundary
   of error, which created larger and larger relative errors as the
   values become larger. This is now replaced with more precise
   arithmetics, using the new mul_u64_u64_div_u64() helper in math64.h.

 - Improve the deadline scheduler, such as making it capacity aware

 - Improve frequency-invariant scheduling

 - Misc cleanups in energy/power aware scheduling

 - Add sched_update_nr_running tracepoint to track changes to nr_running

 - Documentation additions and updates

 - Misc cleanups and smaller fixes

Pull perf event updates from Ingo Molnar:
 "HW support updates:

   - Add uncore support for Intel Comet Lake

   - Add RAPL support for Hygon Fam18h

   - Add Intel "IIO stack to PMON mapping" support on Skylake-SP CPUs,
     which enumerates per device performance counters via sysfs and
     enables the perf stat --iiostat functionality

   - Add support for Intel "Architectural LBRs", which generalized the
     model specific LBR hardware tracing feature into a
     model-independent, architected performance monitoring feature.

     Usage is mostly seamless to tooling, as the pre-existing LBR
     features are kept, but there's a couple of advantages under the
     hood, such as faster context-switching, faster LBR reads, cleaner
     exposure of LBR features to guest kernels, etc.

     ( Since architectural LBRs are supported via XSAVE, there's related
       changes to the x86 FPU code as well. )

  ftrace/perf updates:

   - Add support to add a text poke event to record changes to kernel
     text (i.e. self-modifying code) in order to support tracers like
     Intel PT decoding through jump labels, kprobes and ftrace
     trampolines.

  Misc cleanups, smaller fixes..."
