coccinelle: api: add device_attr_show script
According to the documentation[1] show() methods of device attributes should return the number of bytes printed into the buffer. This is the return value of scnprintf(). show() must not use snprintf() when formatting the value to be returned to user space. snprintf() returns the length the resulting string would be, assuming it all fit into the destination array[2]. scnprintf() return the length of the string actually created in buf. If one can guarantee that an overflow will never happen sprintf() can be used otherwise scnprintf().

random32: move the pseudo-random 32-bit definitions to prandom.h
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.

ACPI updates for 5.9-rc1
- 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).
* Replace one-element array with flexible-array (Gustavo A. R.
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).
- 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.
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).

spi: Updates for v5.9
A fairly quiet release for SPI, nothing really going on in the core
although there's been quite a bit of driver related activity. This pull
request 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.
- Several more GPIO descriptor conversions.
- Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
- New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
R8A774e1.

regulator: Updates for v5.9
This time around the bulk of the work on the regulator API has been
cleanups of various kinds, partly but not entirely inspired by the W=1
stuff that 0day turned on. There's also been a fairly large crop of new
drivers, and a few bugfixes for existing drivers.
- Mode setting support for MT6397 and DA9211.
- New drivers for ChromeOS embedded controllers, Fairchild FAN53880,
NXP PCA9450, Qualcomm LABIBB, MP5496, and VBUS booster, and Silergy

ARM: new SoC support for v5.9
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.

ARM: SoC driver updates for v5.9
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

ARM: SoC DT changes for 5.9
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)

The main changes in this cycle were:
- 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 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

- 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.

These were the main changes in this cycle:
- LKMM updates: mostly documentation changes, but also some new litmus tests for atomic ops.
- KCSAN updates: the most important change is that GCC 11 now has all fixes in place
to support KCSAN, so GCC support can be enabled again. Also more annotations.
- futex updates: minor cleanups and simplifications
- seqlock updates: merge preparatory changes/cleanups for the 'associated locks' facilities.
- lockdep updates:
- simplify IRQ trace event handling
- add various new debug checks
- simplify header dependencies, split out <linux/lockdep_types.h>, decouple
lockdep from other low level headers some more
- fix NMI handling
- misc cleanups and smaller fixes

arm64 and cross-arch updates for 5.9:

which is a NOP on all architectures apart from Alpha, in favour of

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

Merge tag 'rm-unicore32' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/linux
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"

userfaultfd: simplify fault handling
Instead of waiting in a loop for the userfaultfd condition to become true, just wait once and return VM_FAULT_RETRY. We've already dropped the mmap lock, we know we can't really successfully handle the fault at this point and the caller will have to retry anyway. So there's no point in making the wait any more complicated than it needs to be - just schedule away. And once you don't have that complexity with explicit looping, you can also just lose all the 'userfaultfd_signal_pending()' complexity, because once we've set the correct process sleeping state, and don't loop, the act of scheduling itself will be checking if there are any pending signals before going to sleep. We can also drop the VM_FAULT_MAJOR games, since we'll be treating all retried faults as major soon anyway (series to regularize and share more of fault handling across architectures in a separate series by Peter Xu, and in the meantime we won't worry about the possible minor - I'll be here all week, try the veal - accounting difference).
