Merge tag 'random-6.0-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld:
"Though there's been a decent amount of RNG-related development during
this last cycle, not all of it is coming through this tree, as this
cycle saw a shift toward tackling early boot time seeding issues,
which took place in other trees as well.
Here's a summary of the various patches:
- The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot
option have been removed, as they overlapped with the more widely
supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and
"random.trust_cpu". This change allowed simplifying a bit of arch
code.
- x86's RDRAND boot time test has been made a bit more robust, with
RDRAND disabled if it's clearly producing bogus results. This would
be a tip.git commit, technically, but I took it through random.git
to avoid a large merge conflict.
- The RNG has long since mixed in a timestamp very early in boot, on
the premise that a computer that does the same things, but does so
starting at different points in wall time, could be made to still
produce a different RNG state. Unfortunately, the clock isn't set
early in boot on all systems, so now we mix in that timestamp when
the time is actually set.
- User Mode Linux now uses the host OS's getrandom() syscall to
generate a bootloader RNG seed and later on treats getrandom() as
the platform's RDRAND-like faculty.
- The arch_get_random_{seed_,}_long() family of functions is now
arch_get_random_{seed_,}_longs(), which enables certain platforms,
such as s390, to exploit considerable performance advantages from
requesting multiple CPU random numbers at once, while at the same
time compiling down to the same code as before on platforms like
x86.
- A small cleanup changing a cmpxchg() into a try_cmpxchg(), from
Uros.
- A comment spelling fix"
More info about other random number changes that come in through various
architecture trees in the full commentary in the pull request:

* tag 'random-6.0-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random:
random: correct spelling of "overwrites"

timekeeping: contribute wall clock to rng on time change
x86/rdrand: Remove "nordrand" flag in favor of "random.trust_cpu"

Pull selinux updates from Paul Moore:
"A relatively small set of patches for SELinux this time, eight patches
in total with really only one significant change.
The highlights are:
- Add support for proper labeling of memfd_secret anonymous inodes.
This will allow LSMs that implement the anonymous inode hooks to
apply security policy to memfd_secret() fds.
- Various small improvements to memory management: fixed leaks, freed
memory when needed, boundary checks.
- Hardened the selinux_audit_data struct with __randomize_layout.
- A minor documentation tweak to fix a formatting/style issue"

This isn't very efficient, and we even have specific code in io-wq to serialize buffered writes to the same inode to avoid further inefficiencies with thread offload. This is particularly sad since most buffered writes don't block, they simply copy data to a page and dirty it. With this pull request, we can handle buffered writes a lot more effiently. If balance_dirty_pages() needs to block, we back off on writes as indicated. This improves buffered write support by 2-3x.

Thermal control updates for 5.20-rc1
- Consolidate the thermal core code by beginning to move the thermal
trip structure from the thermal OF code as a generic structure to be
used by the different sensors when registering a thermal zone
(Daniel Lezcano).
- Make per cpufreq / devfreq cooling device ops instead of using a
global variable, fix comments and rework the trace information
(Lukasz Luba).
- Add the include/dt-bindings/thermal.h under the area covered by the
thermal maintainer in the MAINTAINERS file (Lukas Bulwahn).
- Improve the error output by giving the sensor identification when a
thermal zone failed to initialize, the DT bindings by changing the
positive logic and adding the r8a779f0 support on the rcar3 (Wolfram
Sang).
- Convert the QCom tsens DT binding to the dtsformat format (Krzysztof
Kozlowski).
- Remove the pointless get_trend() function in the QCom, Ux500 and
tegra thermal drivers, along with the unused DROP_FULL and

Pull thermal control updates from Rafael Wysocki:
"These start a rework of the handling of trip points in the thermal
core, improve the cpufreq/devfreq cooling device handling, update some
thermal control drivers and the tmon utility and clean up code.
Specifics:
- Consolidate the thermal core code by beginning to move the thermal
trip structure from the thermal OF code as a generic structure to
be used by the different sensors when registering a thermal zone
(Daniel Lezcano).
- Make per cpufreq / devfreq cooling device ops instead of using a
global variable, fix comments and rework the trace information
(Lukasz Luba).
- Add the include/dt-bindings/thermal.h under the area covered by the
thermal maintainer in the MAINTAINERS file (Lukas Bulwahn).
- Improve the error output by giving the sensor identification when a
thermal zone failed to initialize, the DT bindings by changing the
positive logic and adding the r8a779f0 support on the rcar3
(Wolfram Sang).
- Convert the QCom tsens DT binding to the dtsformat format
(Krzysztof Kozlowski).
- Remove the pointless get_trend() function in the QCom, Ux500 and
tegra thermal drivers, along with the unused DROP_FULL and
RAISE_FULL trends definitions. Simplify the code by using clamp()
macros (Daniel Lezcano).
- Fix ref_table memory leak at probe time on the k3_j72xx bandgap
(Bryan Brattlof).
- Fix array underflow in prep_lookup_table (Dan Carpenter).
- Add static annotation to the k3_j72xx_bandgap_j7* data structure

pwm: Changes for v5.20-rc1
After v5.19 had all drivers converted to the new atomic API and nobody has reported any breakage, this set of changes starts by dropping the legacy support. Some existing drivers get improvements and broader chip support and a new driver is added that emulates a PWM controller using a clock output. Other than that there's the usual bits of cleanups and minor fixes. -----BEGIN PGP SIGNATURE----- iQJNBAABCAA3FiEEiOrDCAFJzPfAjcif3SOs138+s6EFAmLkCHUZHHRoaWVycnku cmVkaW5nQGdtYWlsLmNvbQAKCRDdI6zXfz6zoRvrD/0VT7JcsM4qHqo1lgzoQF8b KE4H//LnA234/8ucfQQwS0cCOAycl/fA4pRAauFYfM+sg7ENsHA0Oh9Vz6nB+8nu Yn7fL/hjUrUt7MHGGvxmlsoEvEujLFGKggP+qUjDIXxn0eOK9+okTj2WNSnMq6J/ vvCdQY60Qc5LiZIaVFTLEoWxbb/FGJu8U8WvuJiSz3FSTm8TA6PG8BPT9gWMe2eH QM0AejlcUoTt/S9UIBkE1Jdh5BWIj31PChmb4HbsqeI5zNp+9HuImjaGgTK4ZfKC mg6eFzt9JErEQF9TgMKMq4mTQlX3CXFqAzOjCR7/7DH/BUnQKHdumHGkL9btSH8L hUUohD9dVHaD4BT3A8vI08YDqjrtdhnIorbJHZSbScVZT38yGtKyB/vnJWtpa5al phwTEyulq4rwkuwtUQi6M6Lip8jYl0LBd35Q+9+JuDjDgDI00bYNMfe+e4AqTsKO HfIM2J2L3vCk2NWPMMVV1ljywR0q8Qigx8lfzflMDace5mnUrVqEVeU27MQZJ+8u LmW9u7HDSMqaQIQJ2un/coX9vJYH2vr7x5r07tytSgxgEvEkdS9Q1rfIPaQj5ag9 s8crLGnRdkacs92bcHnwHKWtOsx91DWLFlUyGDSlgQZwTciwF99Mlg4gF1CVACd8 RkQbcU+qaSEBpGtYRkFstQ== =TDca -----END PGP SIGNATURE----- Merge tag 'pwm/for-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm updates from Thierry Reding: "After v5.19 had all drivers converted to the new atomic API and nobody has reported any breakage, this set of changes starts by dropping the legacy support.

spi: Updates for v5.20
The big update this time around is some excellent work from David Jander
who went through the fast path and really eliminated overheads, meaning
that we are seeing a huge reduction in the time spent between transfers
for single threaded clients. Benchmarking has been coming out at about a
halving of overhead which is clearly visible in system level usage that
stresses SPI like some CAN and IIO applications, especially with small
transfers. Thanks to David for taking the time to drill down into this
and push the work upstream.
Otherwise there's been a bunch of new device support and the usual
- Optimisation of the fast path, particularly around the number and
types of locking operations, from David Jander.
- Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder Bay,
MediaTek MT8188 and MT8365, Microchip FPGAs, nVidia Tegra 241 and
Samsung Exynos Auto v9 and 4210.

ARM: boardfile deprecation for 6.0
Over the past ten years, new machine support was based on device tree,
and an initial set of about 400 boards using ATAGS with boardfile
for booting were grandfathered in, with about half of them either
removed or converted to DT over time.
Based on the recent mailing list discussion I started, I have now
turned the findings into a set of patches that marks most board files as
'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.
For the boards that are marked as unused, there are two final chances
for potential users: The removal is scheduled to take place after the
longterm stable kernel at the end of 2022, so users can stay on that
version for another few years, and if anyone still has one of these
machines and is planning to keep updating kernels beyond that version,
they can speak up now to have their boards taken off the list again.
Waiting for the LTS release also makes sure that there will be at
least one longterm kernel that contains the recent multiplatform
conversion along while still supporting all legacy boards.
The short summary of the current status is:
- The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
users and will be removed entirely.
- The mmp and davinci platforms have DT support for the important
machines and will become DT-only after this.
- s3c64xx, dove, orion5x, and pxa keep some board files to allow
those to be migrated over to DT more easily, but most board files
are getting removed now. DT support on these platforms is partially
working but requires changes to additional drivers for the other
boards.
- omap1, ep93xx, sa1100, footbridge and rpc have no DT support at
the moment but have some boards with known users. Removing the board
files that nobody uses should make it easier to try a DT conversion
if anyone cares.
There is no explicit timeline what happens with the boards that remain
after this removal, but I expect to revisit this in the future, and
with most boards gone, there will be a good time to do a treewide
review of platform drivers that never gained DT support and have no
remaining in-tree board files.

ARM: new SoC support for 6.0
This adds initial support for two SoC families that have been under review for a while.

ARM: SoC defconfig updates for 6.0
This branch includes the usual updates to defconfig files, enabling additional driver support for the supported platforms. There is also a global refresh for all of them that reorders the lines according to the 'savedefconfig' output, but without removing lines that are no longer part of the refresh. I went through the most common removed lines to also address them while making sure to catch renamed options and add them back under the new name. The boardfile deprecation branch is based on top of this to avoid conflicts against removing the unused boardfile configs from the generic defconfig files. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmLo+14ACgkQmmx57+YA GNnFGw/+Ml2Jich+21ZIcgcAHjrMXq89lCoRa+3clGcxjDl97ZshNumqmRlgXqhM SlcqoA8gxFzx6SAFkCgxmi2m3+Cf8041VglM9YG9zcQnKxvcaRmAnLJ6X8ruwrRy OLHimRi187Wp33c4Y4On0s51g+F+cDHAJA9zmAoGISqPCluTkh/QeD9LXWSfBvFI 6203Hpbge69WzOL520zW7DBaLIRNL8qxSL3Pau6VUwHm2I2GvJ1WHE1S5kQwrd1a LKERfZswaBQtV3RJFRPigEqXzdzWAnD6XBLe1idGzaU52YAY6pxqQHTzOeVxlEPP m+w4jN6wEGK+iu8f0hjEnfr2qtM1Qx45UCvmg+tyY7WIwMWN304WDi+vgCpXPUWp W+IZNk6KPY9Bd3OauFtsiHHz9xXALidJRJT2JojnKDnQKK9J/iTpnBU2fPbpDNiC XOWcbm6e2R7U34LZZE2ursVqPk1iklXfb49/A+nl2x4MkxeX2va1QgyqJf6T6I9y 1avFY4V62lWvrEEMyKu+d7lpRKs3gj0Ky8W/R6+zLlnh4R2r9R+/BJAWi1MiP7qU ZpqWPc7m6cJcUC8Jgf2k+sDG8FNUWn0o6LNbCgv1m5GEYzzr1K9b3+KKV5JB1A9C Hjz9NMRXEOHm+QNvmbgXpCZjx9ga3Av+XAKN4pZ7JG9gc8fnrp0= =2GbW -----END PGP SIGNATURE----- Merge tag 'arm-defconfig-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC defconfig updates from Arnd Bergmann: "This branch includes the usual updates to defconfig files, enabling additional driver support for the supported platforms.

ARM: DT changes for 6.0
As usual, the bulk of the changes for the SoC tree are devicetree file
updates, and most of these changes are for 64-bit embedded machines.
As before, there are a ton of style cleanups, and additional hardware
support for existing machines.
Looking only at the new SoC, the notable additions are:
- A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813.
Each SoC comes with a corresponding reference board.
- The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
i.MX8 embedded SoCs, now using Cortex-A55 cores and the
Ethos-U65 NPU.
- Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end
of Arm based Laptop SoCs, and its automotive cousin, the
SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s
laptop that also gets added here in addition to the reference
boards.
- Allwinner H616, a newer version of the H6 SoC, targeted at
Set-top-box applications. It comes with dts files for the
Orange Pi zero2 single-board computer and the X96 Mate
set-top-box
- Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip
in the Armada SoC family based on the Cortex-A55 core.
New machines based on previously supported SoCs include:
- Several new machines on NXP i.MX platforms: multiple Toradex
Colibri boards using the "Iris" and "Ixora" carriers,
DH electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems
TQMa8MPQL, and phytech phyBOARD-Polis-i.MX8MM.
- Google Chameleon v3 FPGA board based on Intel Arria10 and
Stratix 10 Software Virtual platform, both in the SoCFPGA
platform.
- Two new wireless devices based on Broadcom SoCs:
The Asus GT-AX6000 Router and the Cisco Meraki MR26 access point
- Improved Chromebook support for both the Mediatek and Qualcomm
SoC families brought added machines: Acer Chromebook 514 (MT8192),
Acer Chromebook Spin 513 (MT8195) and a couple of SC7180 based
machines including the Lenovo IdeaPad Chromebook Duet 3.
- Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
- Finally, there are a few development board on other chips:
PCB8309 (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308)
DH DRC Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm
SDM660)

This was a fairly quiet cycle for the locking subsystem:
- lockdep: Fix a handful of the more complex lockdep_init_map_*() primitives
that can lose the lock_type & cause false reports. No such mishap was
observed in the wild.
- jump_label improvements: simplify the cross-arch support of
initial NOP patching by making it arch-specific code (used on MIPS only),
and remove the s390 initial NOP patching that was superfluous.

This cycle's scheduler updates for v6.0 are:
Load-balancing improvements:
============================
- Improve NUMA balancing on AMD Zen systems for affine workloads.
- Improve the handling of reduced-capacity CPUs in load-balancing.
- Energy Model improvements: fix & refine all the energy fairness metrics (PELT),
and remove the conservative threshold requiring 6% energy savings to
migrate a task. Doing this improves power efficiency for most workloads,
and also increases the reliability of energy-efficiency scheduling.
- Optimize/tweak select_idle_cpu() to spend (much) less time searching
for an idle CPU on overloaded systems. There's reports of several
milliseconds spent there on large systems with large workloads ...
[ Since the search logic changed, there might be behavioral side effects. ]
- Improve NUMA imbalance behavior. On certain systems
with spare capacity, initial placement of tasks is non-deterministic,
and such an artificial placement imbalance can persist for a long time,
hurting (and sometimes helping) performance.
The fix is to make fork-time task placement consistent with runtime
NUMA balancing placement.
Note that some performance regressions were reported against this,
caused by workloads that are not memory bandwith limited, which benefit
from the artificial locality of the placement bug(s). Mel Gorman's
conclusion, with which we concur, was that consistency is better than
random workload benefits from non-deterministic bugs:
"Given there is no crystal ball and it's a tradeoff, I think it's
better to be consistent and use similar logic at both fork time
and runtime even if it doesn't have universal benefit."
- Improve core scheduling by fixing a bug in sched_core_update_cookie() that
caused unnecessary forced idling.
- Improve wakeup-balancing by allowing same-LLC wakeup of idle CPUs for newly
woken tasks.
- Fix a newidle balancing bug that introduced unnecessary wakeup latencies.
ABI improvements/fixes:
=======================
- Do not check capabilities and do not issue capability check denial messages
when a scheduler syscall doesn't require privileges. (Such as increasing niceness.)
- Add forced-idle accounting to cgroups too.
- Fix/improve the RSEQ ABI to not just silently accept unknown flags.
(No existing tooling is known to have learned to rely on the previous behavior.)
- Depreciate the (unused) RSEQ_CS_FLAG_NO_RESTART_ON_* flags.
Optimizations:
==============
- Optimize & simplify leaf_cfs_rq_list()
- Micro-optimize set_nr_{and_not,if}_polling() via try_cmpxchg().
Misc fixes & cleanups:
======================
- Fix the RSEQ self-tests on RISC-V and Glibc 2.35 systems.
- Fix a full-NOHZ bug that can in some cases result in the tick not being
re-enabled when the last SCHED_RT task is gone from a runqueue but there's
still SCHED_OTHER tasks around.
- Various PREEMPT_RT related fixes.
- Misc cleanups & smaller fixes.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"Highlights include a major rework of our kPTI page-table rewriting
code (which makes it both more maintainable and considerably faster in
the cases where it is required) as well as significant changes to our
early boot code to reduce the need for data cache maintenance and
greatly simplify the KASLR relocation dance.
Summary:
- Remove unused generic cpuidle support (replaced by PSCI version)
- Fix documentation describing the kernel virtual address space
- Handling of some new CPU errata in Arm implementations
- Rework of our exception table code in preparation for handling
machine checks (i.e. RAS errors) more gracefully
- Switch over to the generic implementation of ioremap()
- Fix lockdep tracking in NMI context
- Instrument our memory barrier macros for KCSAN
- Rework of the kPTI G->nG page-table repainting so that the MMU
remains enabled and the boot time is no longer slowed to a crawl
for systems which require the late remapping
- Enable support for direct swapping of 2MiB transparent huge-pages
on systems without MTE
- Fix handling of MTE tags with allocating new pages with HW KASAN
- Expose the SMIDR register to userspace via sysfs
- Continued rework of the stack unwinder, particularly improving the
behaviour under KASAN
- More repainting of our system register definitions to match the
architectural terminology
- Improvements to the layout of the vDSO objects
- Support for allocating additional bits of HWCAP2 and exposing
FEAT_EBF16 to userspace on CPUs that support it
- Considerable rework and optimisation of our early boot code to
reduce the need for cache maintenance and avoid jumping in and out
of the kernel when handling relocation under KASLR
- Support for disabling SVE and SME support on the kernel
command-line
- Support for the Hisilicon HNS3 PMU
- Miscellanous cleanups, trivial updates and minor fixes"
