Pull x86 fsgsbase from Thomas Gleixner:
"Support for FSGSBASE. Almost 5 years after the first RFC to support
it, this has been brought into a shape which is maintainable and
actually works.
This final version was done by Sasha Levin who took it up after Intel
dropped the ball. Sasha discovered that the SGX (sic!) offerings out
there ship rogue kernel modules enabling FSGSBASE behind the kernels
back which opens an instantanious unpriviledged root hole.
The FSGSBASE instructions provide a considerable speedup of the
context switch path and enable user space to write GSBASE without
kernel interaction. This enablement requires careful handling of the
exception entries which go through the paranoid entry path as they
can no longer rely on the assumption that user GSBASE is positive (as
enforced via prctl() on non FSGSBASE enabled systemn).
All other entries (syscalls, interrupts and exceptions) can still just
utilize SWAPGS unconditionally when the entry comes from user space.
Converting these entries to use FSGSBASE has no benefit as SWAPGS is
only marginally slower than WRGSBASE and locating and retrieving the
kernel GSBASE value is not a free operation either. The real benefit
of RD/WRGSBASE is the avoidance of the MSR reads and writes.
The changes come with appropriate selftests and have held up in field
testing against the (sanitized) Graphene-SGX driver"

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

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).
- Update the ACPICA code in the kernel to upstream revision 20200717:
* Prevent operation region reference counts from overflowing in
some cases (Erik Kaneda).

Silva).
- Fix ACPI PCI hotplug reference counting (Rafael Wysocki).
- Drop last bits of the ACPI procfs interface (Thomas Renninger).
- Drop some redundant checks from the code parsing ACPI tables
related to NUMA (Hanjun Guo).

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.
Silva).
- Drop redundant variable initialization from the APEI code (Colin
Ian King).
- Drop uninitialized_var() from the ACPI PAD driver (Jason Yan).
- Replace HTTP links with HTTPS ones in the ACPI code (Alexander A.
Klimov)"

Pull power management updates from Rafael Wysocki:
"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
table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
RAPL driver), some new functionality in the existing drivers (eg. a
new switch to disable/enable CPU energy-efficiency optimizations in
intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq

devfreq), including the elimination of W=1 build warnings from cpufreq
done by Lee Jones.
Specifics:
- Make the Energy Model cover non-CPU devices (Lukasz Luba).

core_initcall level and allow the default cpufreq governor to be
specified in the kernel command line (Quentin Perret).
- Extend, fix and clean up the intel_pstate driver (Srinivas
Pandruvada, Rafael Wysocki):
* 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
mode.
* Eliminate a static checker warning and clean up a kerneldoc
comment.
- Clean up some variable declarations in the powernv cpufreq driver
(Wei Yongjun).
- Fix up the ->enter_s2idle callback definition to cover the case
when it points to the same function as ->idle correctly (Neal Liu).
- Rearrange and clean up the PSCI cpuidle driver (Ulf Hansson).
- Make the PM core emit "changed" uevent when adding/removing the
"wakeup" sysfs attribute of devices (Abhishek Pandit-Subedi).
- Add a helper macro for declaring PM callbacks and use it in the MMC
jz4740 driver (Paul Cercueil).
- Fix white space in some places in the hibernate code and make the
system-wide PM code use "const char *" where appropriate (Xiang
Chen, Alexey Dobriyan).
- Add one more "unsafe" helper macro to the freezer to cover the NFS
use case (He Zhe).
- Change the language in the generic PM domains framework to use
parent/child terminology and clean up a typo and some comment
fromatting in that code (Kees Cook, Geert Uytterhoeven).

"A fairly quiet release for SPI, nothing really going on in the core

This includes the addition of some shared code in drivers/memory for
the Renesas RPC-IF which is used by a newly added SPI driver, the
memory subsystem doesn't seem to have a fixed maintainer at the minute
and this seemed like the most sensible way to get that hardware
supported.
- Quite a few cleanups and optimizations for the Altera, Qualcomm
GENI, sun6i and lantiq drivers.

- 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

- 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

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

- 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. )

Pull arm64 and cross-arch updates from Catalin Marinas:
"Here's a slightly wider-spread set of updates for 5.9.
Going outside the usual arch/arm64/ area is the removal of
read_barrier_depends() series from Will and the MSI/IOMMU ID
translation series from Lorenzo.
The notable arm64 updates include ARMv8.4 TLBI range operations and
translation level hint, time namespace support, and perf.
Summary:
- Removal of the tremendously unpopular read_barrier_depends()
barrier, which is a NOP on all architectures apart from Alpha, in
favour of allowing architectures to override READ_ONCE() and do
whatever dance they need to do to ensure address dependencies
provide LOAD -> LOAD/STORE ordering.
This work also offers a potential solution if compilers are shown
to convert LOAD -> LOAD address dependencies into control
dependencies (e.g. under LTO), as weakly ordered architectures will
effectively be able to upgrade READ_ONCE() to smp_load_acquire().
The latter case is not used yet, but will be discussed further at
LPC.
- Make the MSI/IOMMU input/output ID translation PCI agnostic,
augment the MSI/IOMMU ACPI/OF ID mapping APIs to accept an input ID
bus-specific parameter and apply the resulting changes to the
device ID space provided by the Freescale FSL bus.
- arm64 support for TLBI range operations and translation table level
hints (part of the ARMv8.4 architecture version).
- Time namespace support for arm64.
- Export the virtual and physical address sizes in vmcoreinfo for
makedumpfile and crash utilities.
- CPU feature handling cleanups and checks for programmer errors
(overlapping bit-fields).
- ACPI updates for arm64: disallow AML accesses to EFI code regions
and kernel memory.
- perf updates for arm64.
- Miscellaneous fixes and cleanups, most notably PLT counting
optimisation for module loading, recordmcount fix to ignore
relocations other than R_AARCH64_CALL26, CMA areas reserved for
gigantic pages on 16K and 64K configurations.
- Trivial typos, duplicate words"

Pull unicore32 removal from Mike Rapoport:
"Remove unicore32 support.
The unicore32 port do not seem maintained for a long time now, there
is no upstream toolchain that can create unicore32 binaries and all
the links to prebuilt toolchains for unicore32 are dead. Even
compilers that were available are not supported by the kernel anymore.
Guenter Roeck says:
"I have stopped building unicore32 images since v4.19 since there is
no available compiler that is still supported by the kernel. I am
surprised that support for it has not been removed from the kernel"
However, it's worth pointing out two things:
- Guan Xuetao is still listed as maintainer and asked for the port to
be kept around the last time Arnd suggested removing it two years
ago. He promised that there would be compiler sources (presumably
llvm), but has not made those available since.
- https://github.com/gxt has patches to linux-4.9 and qemu-2.7, both
released in 2016, with patches dated early 2019. These patches
mainly restore a syscall ABI that was never part of mainline Linux
but apparently used in production. qemu-2.8 removed support for
that ABI and newer kernels (4.19+) can no longer be built with the
old toolchain, so apparently there will not be any future updates
to that git tree"

Pull fscrypt updates from Eric Biggers:
"This release, we add support for inline encryption via the blk-crypto
framework which was added in 5.8.
Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt',
the contents of encrypted files will be encrypted/decrypted via
blk-crypto, instead of directly using the crypto API. This model
allows taking advantage of the inline encryption hardware that is
integrated into the UFS or eMMC host controllers on most mobile SoCs.
Note that this is just an alternate implementation; the ciphertext
written to disk stays the same.
(This pull request does *not* include support for direct I/O on
encrypted files, which blk-crypto makes possible, since that part is
still being discussed.)
Besides the above feature update, there are also a few fixes and
cleanups, e.g. strengthening some memory barriers that may be too
weak.
All these patches have been in linux-next with no reported issues.
I've also tested them with the fscrypt xfstests, as usual. It's also
been tested that the inline encryption support works with the support
for Qualcomm and Mediatek inline encryption hardware that will be in
the scsi pull request for 5.9. Also, several SoC vendors are already
using a previous, functionally equivalent version of these patches"

a21ee6055c30 ("lockdep: Change hardirq{s_enabled,_context} to per-cpu variables")
and this fresh upstream commit:
aa54ea903abb ("ARM: percpu.h: fix build error")
a21ee6055c30 is a simpler solution to the dependency problem and doesn't
further increase header hell - so this conflict resolution effectively
reverts aa54ea903abb and uses the a21ee6055c30 solution.

- Add support for zstd compressed kernel
- Define __DISABLE_EXPORTS in Makefile
- Remove __DISABLE_EXPORTS definition from kaslr.c
- Bump the heap size for zstd.
- Update the documentation.
Integrates the ZSTD decompression code to the x86 pre-boot code.
Zstandard requires slightly more memory during the kernel decompression
on x86 (192 KB vs 64 KB), and the memory usage is independent of the
window size.
__DISABLE_EXPORTS is now defined in the Makefile, which covers both
the existing use in kaslr.c, and the use needed by the zstd decompressor
in misc.c.
This patch has been boot tested with both a zstd and gzip compressed
kernel on i386 and x86_64 using buildroot and QEMU.
Additionally, this has been tested in production on x86_64 devices.
We saw a 2 second boot time reduction by switching kernel compression
from xz to zstd.
