Pull ACPI updates from Rafael Wysocki: "These rework the handling of ACPI device objects to use the driver core facilities for managing child ones instead of some questionable home-grown ways without the requisite locking and reference counting, clean up the EC driver, improve suspend-to-idle handling on x86, add some systems to the ACPI backlight quirk list, fix some assorted issues, clean up code and improve documentation. Specifics: - Use facilities provided by the driver core and some additional helpers to handle the children of a given ACPI device object in multiple places instead of using the children and node list heads in struct acpi_device which is error prone (Rafael Wysocki). - Fix ACPI-related device reference counting issue in the hisi_lpc bus driver (Yang Yingliang). - Drop the children and node list heads that are not needed any more from struct acpi_device (Rafael Wysocki). - Drop driver member from struct acpi_device (Uwe Kleine-König). - Drop redundant check from acpi_device_remove() (Uwe Kleine-König). - Prepare the CPPC library for handling backwards-compatible future _CPC return package formats gracefully (Rafael Wysocki). - Clean up the ACPI EC driver after previous changes in it (Hans de Goede). - Drop leftover acpi_processor_get_limit_info() declaration (Riwen Lu). - Split out thermal initialization from ACPI PSS (Riwen Lu). - Annotate more functions in the ACPI CPU idle driver to live in the cpuidle section (Guilherme G. Piccoli). - Fix _EINJ vs "special purpose" EFI memory regions (Dan Williams). - Implement a better fix to avoid spamming the console with old error logs (Tony Luck). - Fix typo in a comment in the APEI code (Xiang wangx). - Save NVS memory during transitions into S3 on Lenovo G40-45 (Manyi Li). - Add support for upcoming AMD uPEP device ID AMDI008 to the ACPI suspend-to-idle driver for x86 platforms (Shyam Sundar S K). - Clean up checks related to the ACPI_FADT_LOW_POWER_S0 platform flag in the LPIT table driver and the suspend-to-idle driver for x86 platforms (Rafael Wysocki). - Print information messages regarding declared LPS0 idle support in the platform firmware (Rafael Wysocki). - Fix missing check in register_device_clock() in the ACPI driver for Intel SoCs (huhai). - Fix ACS setup in the VIOT table parser (Eric Auger). - Skip IRQ override on AMD Zen platforms where it's harmful (Chuanhong Guo). - Use native backlight on Dell Inspiron N4010 (Hans de Goede). - Use native backlight on some TongFang devices (Werner Sembach). - Drop X86 dependency from the ACPI backlight driver Kconfig (Riwen Lu). - Shorten the quirk list in the ACPI backlight driver by identifying Clevo by board_name only (Werner Sembach). - Remove useless NULL pointer checks from 2 ACPI PCI link management functions (Andrey Strachuk). - Fix obsolete example in the ACPI EINJ documentation (Qifu Zhang). - Update links and references to _DSD-related documents (Sudeep Holla)" * tag 'acpi-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (46 commits) ACPI/PCI: Remove useless NULL pointer checks ACPI: CPPC: Do not prevent CPPC from working in the future ACPI: PM: x86: Print messages regarding LPS0 idle support ACPI: resource: skip IRQ override on AMD Zen platforms Documentation: ACPI: EINJ: Fix obsolete example ACPI: video: Use native backlight on Dell Inspiron N4010 ACPI: PM: s2idle: Use LPS0 idle if ACPI_FADT_LOW_POWER_S0 is unset Revert "ACPI / PM: LPIT: Register sysfs attributes based on FADT" ACPI: video: Shortening quirk list by identifying Clevo by board_name only ACPI: video: Force backlight native for some TongFang devices ACPI: PM: s2idle: Add support for upcoming AMD uPEP HID AMDI008 ACPI: VIOT: Fix ACS setup ACPI: bus: Drop unused list heads from struct acpi_device hisi_lpc: Use acpi_dev_for_each_child() bus: hisi_lpc: fix missing platform_device_put() in hisi_lpc_acpi_probe() ACPI: bus: Drop driver member of struct acpi_device ACPI: bus: Drop redundant check in acpi_device_remove() ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP ACPI: LPSS: Fix missing check in register_device_clock() ACPI: APEI: Better fix to avoid spamming the console with old error logs ...

Pull spi updates from Mark Brown: "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 updates. - 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" * tag 'spi-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (97 commits) MAINTAINERS: add spi support to GXP spi: dt-bindings: add documentation for hpe,gxp-spifi spi: spi-gxp: Add support for HPE GXP SoCs spi: a3700: support BE for AC5 SPI driver spi/panel: dt-bindings: drop CPHA and CPOL from common properties spi: bcm2835: enable shared interrupt support spi: dt-bindings: spi-controller: correct example indentation spi: dt-bindings: qcom,spi-geni-qcom: allow three interconnects spi: npcm-fiu: Add NPCM8XX support dt-binding: spi: Add npcm845 compatible to npcm-fiu document spi: npcm-fiu: Modify direct read dummy configuration spi: atmel: remove #ifdef CONFIG_{PM, SLEEP} spi: dt-bindings: Add compatible for MediaTek MT8188 spi: dt-bindings: mediatek,spi-mtk-nor: Update bindings for nor flash spi: dt-bindings: atmel,at91rm9200-spi: convert to json-schema spi: tegra20-slink: fix UAF in tegra_slink_remove() spi: Fix simplification of devm_spi_register_controller spi: microchip-core: switch to use dev_err_probe() spi: microchip-core: switch to use devm_spi_alloc_master() spi: microchip-core: fix UAF in mchp_corespi_remove() ...

Pull ARM boardfile deprecation from Arnd Bergmann: "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" Link: https://lore.kernel.org/linux-arm-kernel/CAK8P3a0Z9vGEQbVRBo84bSyPFM-LF+hs5w8ZA51g2Z+NsdtDQA@mail.gmail.com/ * tag 'arm-boardfiles-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: ARM: cns3xxx: add CONFIG_UNUSED_BOARD_FILES dependency ARM: iop32x: mark as unused ARM: s3c: mark most board files as unused ARM: omap1: add Kconfig dependencies for unused boards ARM: sa1100: mark most boards as unused ARM: footbridge: mark cats board for removal ARM: mmp: mark all board files for removal ARM: ep93xx: mark most board files as unused ARM: davinci: mark all ATAGS board files as unused ARM: orion: add ATAGS dependencies ARM: pxa: add Kconfig dependencies for ATAGS based boards ARM: add CONFIG_UNUSED_BOARD_FILES ARM: add ATAGS dependencies to non-DT platforms

Pull ARM new SoC support from Arnd Bergmann: "This adds initial support for two SoC families that have been under review for a while. In both cases, the origonal idea was to have a minimally functional version, but we ended up leaving out the clk drivers that are still under review and will be merged through the corresponding subsystem tree.

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. 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.

Pull scheduler updates from Ingo Molnar: "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().

Merge tag 'fs.idmapped.overlay.acl.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull acl updates from Christian Brauner: "Last cycle we introduced support for mounting overlayfs on top of idmapped mounts. While looking into additional testing we realized that posix acls don't really work correctly with stacking filesystems on top of idmapped layers. We already knew what the fix were but it would require work that is more suitable for the merge window so we turned off posix acls for v5.19 for overlayfs on top of idmapped layers with Miklos routing my patch upstream in 72a8e05d ("Merge tag 'ovl-fixes-5.19-rc7' [..]"). This contains the work to support posix acls for overlayfs on top of idmapped layers. Since the posix acl fixes should use the new vfs{g,u}id_t work the associated branch has been merged in. (We sent a pull request for this earlier.) We've also pulled in Miklos pull request containing my patch to turn of posix acls on top of idmapped layers. This allowed us to avoid rebasing the branch which we didn't like because we were already at rc7 by then. Merging it in allows this branch to first fix posix acls and then to cleanly revert the temporary fix it brought in by commit 4a47c638 ("ovl: turn of SB_POSIXACL with idmapped layers temporarily"). The last patch in this series adds Seth Forshee as a co-maintainer for idmapped mounts. Seth has been integral to all of this work and is also the main architect behind the filesystem idmapping work which ultimately made filesystems such as FUSE and overlayfs available in containers. He continues to be active in both development and review. I'm very happy he decided to help and he has my full trust. This increases the bus factor which is always great for work like this. I'm honestly very excited about this because I think in general we don't do great in the bringing on new maintainers department" For more explanations of the ACL issues, see https://lore.kernel.org/all/20220801145520.1532837-1-brauner@kernel.org/ * tag 'fs.idmapped.overlay.acl.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: Add Seth Forshee as co-maintainer for idmapped mounts Revert "ovl: turn of SB_POSIXACL with idmapped layers temporarily" ovl: handle idmappings in ovl_get_acl() acl: make posix_acl_clone() available to overlayfs acl: port to vfs{g,u}id_t acl: move idmapped mount fixup into vfs_{g,s}etxattr() mnt_idmapping: add vfs[g,u]id_into_k[g,u]id()

Pull fs idmapping updates from Christian Brauner: "This introduces the new vfs{g,u}id_t types we agreed on. Similar to k{g,u}id_t the new types are just simple wrapper structs around regular {g,u}id_t types. They allow to establish a type safety boundary in the VFS for idmapped mounts preventing confusion betwen {g,u}ids mapped into an idmapped mount and {g,u}ids mapped into the caller's or the filesystem's idmapping. An initial set of helpers is introduced that allows to operate on vfs{g,u}id_t types. We will remove all references to non-type safe idmapped mounts helpers in the very near future. The patches do already exist. This converts the core attribute changing codepaths which become significantly easier to reason about because of this change. Just a few highlights here as the patches give detailed overviews of what is happening in the commit messages: - The kernel internal struct iattr contains type safe vfs{g,u}id_t values clearly communicating that these values have to take a given mount's idmapping into account. - The ownership values placed in struct iattr to change ownership are identical for idmapped and non-idmapped mounts going forward. This also allows to simplify stacking filesystems such as overlayfs that change attributes In other words, they always represent the values. - Instead of open coding checks for whether ownership changes have been requested and an actual update of the inode is required we now have small static inline wrappers that abstract this logic away removing a lot of code duplication from individual filesystems that all open-coded the same checks" * tag 'fs.idmapped.vfsuid.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: mnt_idmapping: align kernel doc and parameter order mnt_idmapping: use new helpers in mapped_fs{g,u}id() fs: port HAS_UNMAPPED_ID() to vfs{g,u}id_t mnt_idmapping: return false when comparing two invalid ids attr: fix kernel doc attr: port attribute changes to new types security: pass down mount idmapping to setattr hook quota: port quota helpers mount ids fs: port to iattr ownership update helpers fs: introduce tiny iattr ownership update helpers fs: use mount types in iattr fs: add two type safe mapping helpers mnt_idmapping: add vfs{g,u}id_t

Previously, the immediate cleanup would lead to extraneous warnings when the result arrived. - Tracepoint improvements, e.g. adding the lock resource name. - Delay the completion of lockspace creation until one full recovery cycle has completed. This allows more error cases to be returned to the caller. - Remove warnings from the locking layer about delayed network replies. The recently added midcomms warnings are much more useful. - Begin the process of deprecating two unused lock-timeout-related features. These features now require enabling via a Kconfig option, and enabling them triggers deprecation warnings.

The unhold_lkb() function decrements the lock's kref, and asserts that the ref count was not the final one. Use the kref_put release function (which should not be called) to call the assert, rather than doing the assert based on the kref_put return value. Using kill_lkb() as the release function doesn't make sense if we only want to assert. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>

This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option that must be enabled to use two timeout-related features that we intend to remove in kernel v6.2. Warnings are printed if either is enabled and used. Neither has ever been used as far as we know. . The DLM_LSFL_TIMEWARN lockspace creation flag will be removed, along with the associated configfs entry for setting the timeout. Setting the flag and configfs file would cause dlm to track how long locks were waiting for reply messages. After a timeout, a kernel message would be logged, and a netlink message would be sent to userspace. Recently, midcomms messages have been added that produce much better logging about actual problems with messages. No use has ever been found for the netlink messages. . The userspace libdlm API has allowed the DLM_LKF_TIMEOUT flag with a timeout value to be set in lock requests. The lock request would be cancelled after the timeout.
