Pull SoC DT updates from Arnd Bergmann: "About a quarter of the changes are for 32-bit arm, mostly filling in device support for existing machines and adding minor cleanups, mostly for Qualcomm and Samsung based machines. Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from Rockchips that have been around for a while but were lacking kernel support so far: RV1126 is a Vision SoC with an NPU and is used in the Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design for TV boxes and so far only comes with a dts for its refernece design. The other 32-bit boards that were added are two ASpeed AST2600 based BMC boards, the Microchip sam9x60_curiosity development board (Armv5 based!), the Enclustra PE1 FPGA-SoM baseboard, and a few more boards for i.MX53 and i.MX6ULL. On the RISC-V side, there are fewer patches, but a total of ten new single-board computers based on variations of the Allwinner D1/T113 chip, plus one more board based on Microchip Polarfire. As usual, arm64 has by far the most changes here, with over 700 non-merge changesets, among them over 400 alone for Qualcomm. The newly added SoCs this time are all recent high-end embedded SoCs for various markets, each on comes with support for its reference board: - Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones - Qualcomm QDU1000/QRU1000 5G RAN platform - Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs - TI J784S4 for industrial and automotive applications In total, there are 46 new arm64 machines: - Reference platforms for each of the five new SoCs - Three Amlogic based development boards - Six embedded machines based on NXP i.MX8MM and i.MX8MP - The Mediatek mt7986a based Banana Pi R3 router - Six tablets based on Qualcomm MSM8916 (Snapdragon 410), SM6115 (Snapdragon 662) and SM8250 (Snapdragon 865) - Two LTE dongles, also based on MSM8916 - Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610), SDM450 and SDM632 - Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c) - Nine development boards based on Rockchips RK3588, RK3568, RK3566 and RK3328. - Five development machines based on TI K3 (AM642/AM654/AM68/AM69) The cleanup of dtc warnings continues across all platforms, adding to the total number of changes" * tag 'soc-dt-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (1035 commits) dt-bindings: riscv: correct starfive visionfive 2 compatibles ARM: dts: socfpga: Add enclustra PE1 devicetree dt-bindings: altera: Add enclustra mercury PE1 arm64: dts: qcom: msm8996: align RPM G-Link clock-controller node with bindings arm64: dts: qcom: qcs404: align RPM G-Link node with bindings arm64: dts: qcom: ipq6018: align RPM G-Link node with bindings arm64: dts: qcom: sm8550: remove invalid interconnect property from cryptobam arm64: dts: qcom: sc7280: Adjust zombie PWM frequency arm64: dts: qcom: sc8280xp-pmics: Specify interrupt parent explicitly arm64: dts: qcom: sm7225-fairphone-fp4: enable remaining i2c busses arm64: dts: qcom: sm7225-fairphone-fp4: move status property down arm64: dts: qcom: pmk8350: Use the correct PON compatible arm64: dts: qcom: sc8280xp-x13s: Enable external display arm64: dts: qcom: sc8280xp-crd: Introduce pmic_glink arm64: dts: qcom: sc8280xp: Add USB-C-related DP blocks arm64: dts: qcom: sm8350-hdk: enable GPU arm64: dts: qcom: sm8350: add GPU, GMU, GPU CC and SMMU nodes arm64: dts: qcom: sm8350: finish reordering nodes arm64: dts: qcom: sm8350: move more nodes to correct place arm64: dts: qcom: sm8350: reorder device nodes ...

Pull ARM defconfigs updates from Arnd Bergmann: "As usual, this contains all the patches to enable options for newly added device drivers in the 32-bit and 64-bit defconfig files. I have sorted the files according to the changes to Kconfig files, to make it easier to check what has changed compared to the 'make savedefconfig' output. The most notable change this time is a series from Mark Brown to add a 'virtconfig' target for arm64, which is for the moment the same as the 'defconfig' target but disables all the top-level SoC specific options in order to have a smaller and faster kernel build" * tag 'soc-defconfig-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (39 commits) arm64: defconfig: enable drivers required by the Qualcomm SA8775P platform arm64: defconfig: Enable DisplayPort on SC8280XP laptops arm64: configs: Add virtconfig kbuild: Provide a version of merge_into_defconfig without override warnings scripts: merge_config: Add option to suppress warning on overrides ARM: reorder defconfig files arm64: reorder defconfig arm64: defconfig: enable Qualcomm SDAM nvmem driver arm64: defconfig: enable SM8450 DISPCC clock driver ARM: defconfig: Add IOSCHED_BFQ to the default configs ARM: configs: multi_v7: enable NVMEM driver for STM32 ARM: Add wpcm450_defconfig for Nuvoton WPCM450 arm64: defconfig: Enable DMA_RESTRICTED_POOL arm64: defconfig: Enable missing configs for mt8192-asurada riscv: defconfig: Enable the Allwinner D1 platform and drivers ARM: imx_v6_v7_defconfig: Don't enable PROVE_LOCKING ARM: multi_v7_defconfig: Add GXP Fan and SPI support ARM: add multi_v7_lpae_defconfig kbuild: Add config fragment merge functionality ARM: multi_v7_defconfig: Add options to support TQMLS102xA series ...

Pull ARM SoC boardfile updates from Arnd Bergmann "Unused boardfile removal for 6.3 This is a follow-up to the deprecation of most of the old-style board files that was merged in linux-6.0, removing them for good. This branch is almost exclusively dead code removal based on those annotations. Some device driver removals went through separate subsystem trees, but the majority is in the same branch, in order to better handle dependencies between the patches and avoid breaking bisection. Unfortunately that leads to merge conflicts against other changes in the subsystem trees, but they should all be trivial to resolve by removing the files. See commit 7d0d3fa7 ("Merge tag 'arm-boardfiles-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the description of which machines were marked unused and are now removed. The only removals that got postponed are Terastation WXL (mv78xx0) and Jornada720 (StrongARM1100), which turned out to still have potential users" * tag 'arm-boardfile-remove-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (91 commits) mmc: omap: drop TPS65010 dependency ARM: pxa: restore mfp-pxa320.h usb: ohci-omap: avoid unused-variable warning ARM: debug: remove references in DEBUG_UART_8250_SHIFT to removed configs ARM: s3c: remove obsolete s3c-cpu-freq header MAINTAINERS: adjust SAMSUNG SOC CLOCK DRIVERS after s3c24xx support removal MAINTAINERS: update file entries after arm multi-platform rework and mach-pxa removal ARM: remove CONFIG_UNUSED_BOARD_FILES mfd: remove htc-pasic3 driver w1: remove ds1wm driver usb: remove ohci-tmio driver fbdev: remove w100fb driver fbdev: remove tmiofb driver mmc: remove tmio_mmc driver mfd: remove ucb1400 support mfd: remove toshiba tmio drivers rtc: remove v3020 driver power: remove pda_power supply driver ASoC: pxa: remove unused board support pcmcia: remove unused pxa/sa1100 drivers ...

Pull btrfs updates from David Sterba: "The usual mix of performance improvements and new features. The core change is reworking how checksums are processed, with followup cleanups and simplifications. There are two minor changes in block layer and iomap code.

Pull erofs updates from Gao Xiang: "The most noticeable feature for this cycle is per-CPU kthread decompression since Android use cases need low-latency I/O handling in order to ensure the app runtime performance, currently unbounded workqueue latencies are not quite good for production on many aarch64 hardwares and thus we need to introduce a deterministic expectation for these. Decompression is CPU-intensive and it is sleepable for EROFS, so other alternatives like decompression under softirq contexts are not considered. More details are in the corresponding commit message. Others are random cleanups around the whole codebase and we will continue to clean up further in the next few months. Due to Lunar New Year holidays, some other new features were not completely reviewed and solidified as expected and we may delay them into the next version.

Pull vfs hardening update from Christian Brauner: "Jan pointed out that during shutdown both filp_close() and super block destruction will use basic printk logging when bugs are detected. This causes issues in a few scenarios: - Tools like syzkaller cannot figure out that the logged message indicates a bug. - Users that explicitly opt in to have the kernel bug on data corruption by selecting CONFIG_BUG_ON_DATA_CORRUPTION should see the kernel crash when they did actually select that option. - When there are busy inodes after the superblock is shut down later access to such a busy inodes walks through freed memory. It would be better to cleanly crash instead. All of this can be addressed by using the already existing CHECK_DATA_CORRUPTION() macro in these places when kernel bugs are detected. Its logging improvement is useful for all users. Otherwise this only has a meaningful behavioral effect when users do select CONFIG_BUG_ON_DATA_CORRUPTION which means this is backward compatible for regular users" * tag 'fs.v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping: fs: Use CHECK_DATA_CORRUPTION() when kernel bugs are detected

Pull vfs idmapping updates from Christian Brauner: - Last cycle we introduced the dedicated struct mnt_idmap type for mount idmapping and the required infrastucture in 256c8aed ("fs: introduce dedicated idmap type for mounts"). As promised in last cycle's pull request message this converts everything to rely on struct mnt_idmap. Currently we still pass around the plain namespace that was attached to a mount. This is in general pretty convenient but it makes it easy to conflate namespaces that are relevant on the filesystem with namespaces that are relevant on the mount level. Especially for non-vfs developers without detailed knowledge in this area this was a potential source for bugs. This finishes the conversion. Instead of passing the plain namespace around this updates all places that currently take a pointer to a mnt_userns with a pointer to struct mnt_idmap. Now that the conversion is done all helpers down to the really low-level helpers only accept a struct mnt_idmap argument instead of two namespace arguments. Conflating mount and other idmappings will now cause the compiler to complain loudly thus eliminating the possibility of any bugs. This makes it impossible for filesystem developers to mix up mount and filesystem idmappings as they are two distinct types and require distinct helpers that cannot be used interchangeably. Everything associated with struct mnt_idmap is moved into a single separate file. With that change no code can poke around in struct mnt_idmap. It can only be interacted with through dedicated helpers. That means all filesystems are and all of the vfs is completely oblivious to the actual implementation of idmappings. We are now also able to extend struct mnt_idmap as we see fit. For example, we can decouple it completely from namespaces for users that don't require or don't want to use them at all. We can also extend the concept of idmappings so we can cover filesystem specific requirements. In combination with the vfs{g,u}id_t work we finished in v6.2 this makes this feature substantially more robust and thus difficult to implement wrong by a given filesystem and also protects the vfs. - Enable idmapped mounts for tmpfs and fulfill a longstanding request. A long-standing request from users had been to make it possible to create idmapped mounts for tmpfs. For example, to share the host's tmpfs mount between multiple sandboxes. This is a prerequisite for some advanced Kubernetes cases. Systemd also has a range of use-cases to increase service isolation. And there are more users of this. However, with all of the other work going on this was way down on the priority list but luckily someone other than ourselves picked this up. As usual the patch is tiny as all the infrastructure work had been done multiple kernel releases ago. In addition to all the tests that we already have I requested that Rodrigo add a dedicated tmpfs testsuite for idmapped mounts to xfstests. It is to be included into xfstests during the v6.3 development cycle. This should add a slew of additional tests. * tag 'fs.idmapped.v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping: (26 commits) shmem: support idmapped mounts for tmpfs fs: move mnt_idmap fs: port vfs{g,u}id helpers to mnt_idmap fs: port fs{g,u}id helpers to mnt_idmap fs: port i_{g,u}id_into_vfs{g,u}id() to mnt_idmap fs: port i_{g,u}id_{needs_}update() to mnt_idmap quota: port to mnt_idmap fs: port privilege checking helpers to mnt_idmap fs: port inode_owner_or_capable() to mnt_idmap fs: port inode_init_owner() to mnt_idmap fs: port acl to mnt_idmap fs: port xattr to mnt_idmap fs: port ->permission() to pass mnt_idmap fs: port ->fileattr_set() to pass mnt_idmap fs: port ->set_acl() to pass mnt_idmap fs: port ->get_acl() to pass mnt_idmap fs: port ->tmpfile() to pass mnt_idmap fs: port ->rename() to pass mnt_idmap fs: port ->mknod() to pass mnt_idmap fs: port ->mkdir() to pass mnt_idmap ...

With no remaining callers of get_kernel_pages() the function is removed" [ This looks like it's just some random 'tee' cleanup, but the bigger picture impetus for this is really to to to remove historical confusion with mixed use of kernel virtual addresses and 'struct page' pointers. Kernel virtual pointers in the vmalloc space is then particularly confusing - both for looking up a page pointer (when trying to then unify a "virtual address or page" interface) and _particularly_ when mixed with HIGHMEM support and the kmap*() family of remapping. This is particularly true with HIGHMEM getting much less test coverage with 32-bit architectures being increasingly legacy targets. So we actively wanted to remove get_kernel_pages() to make sure nobody else used it too, and thus the 'tee' part is "finally remove last user". See also commit 6647e76a ("v4l2: don't fall back to follow_pfn() if pin_user_pages_fast() fails") for a totally different version of a conceptually similar "let's stop this confusion of different ways of referring to memory". - Linus ] * tag 'remove-get_kernel_pages-for-6.3' of https://git.linaro.org/people/jens.wiklander/linux-tee: mm: Remove get_kernel_pages() tee: Remove call to get_kernel_pages() tee: Remove vmalloc page support highmem: Enhance is_kmap_addr() to check kmap_local_page() mappings
