Pull ARM SoC updates from Arnd Bergmann:
"These are mostly cosmetic changes and minor bugfixes for the SoC
specific code, across the 32-bit at91, mvebu, davinci, samsung, and
omap platforms.
The main notable changes are for the Samsung Exynos platform, which
sees a rewrite of gpio handling and a change to restore and adds a
workaround for a problem with cpuidle support"

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)
- Arm Versatile
- Broadcom (board updates for switch ports, Raspberry pi clock updates)
- Hisilicon (various)
- Intel/Altera SoCFPGA (various)
- Marvell Armada 7xxx/8xxx (smmu)
- Marvell MMP (GPU on mmp2/mmp3)
- Mediatek mt8183 (USB, pericfg)
- NXP Layerscape (VPU, thermal, DSPI)
- NXP i.MX (VPU, bindings, board updates)
- Nvidia Tegra194 (GPU)
- Qualcomm (GPU, Interconnect, ...)
- Renesas R-Car (SPI, IPMMU, board updates)
- STMicroelectronics STM32 (various)
- Samsung Exynos (various)
- Socionext Uniphier (updates to serial, and pcie)
- TI K3 (serdes, usb3, audio, sd, chipid)
- TI OMAP (IPU/DSP remoteproc changes, dropping platform data)"

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. )

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

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"

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.

Bump the ZO_z_extra_bytes margin for zstd.
Zstd needs 3 bytes per 128 KB, and has a 22 byte fixed overhead.
Zstd needs to maintain 128 KB of space at all times, since that is
the maximum block size. See the comments regarding in-place
decompression added in lib/decompress_unzstd.c for details.
The existing code is written so that all the compression algorithms use
the same ZO_z_extra_bytes. It is taken to be the maximum of the growth
rate plus the maximum fixed overhead. The comments just above this diff
state that:

The carry variables are assigned but never used, which upsets
the compiler. This patch removes them.

'Commit 8566ac8b8e7c ("KVM: SVM: Implement pause loop exit logic in SVM")'
drops disable pause loop exit/pause filtering capability completely, I
guess it is a merge fault by Radim since disable vmexits capabilities and
pause loop exit for SVM patchsets are merged at the same time. This patch
reintroduces the disable pause loop exit/pause filtering capability support.

Although iph is expected to point to at least 20 bytes of valid memory,
ihl may be bogus, for example on reception of a corrupt packet. If it
happens to be less than 5, we really don't want to run away and
dereference 16GB worth of memory until it wraps back to exactly zero...
