Pull s390 updates from Heiko Carstens: "Besides all the small improvements and cleanups the most notable part is the fast vector/SIMD implementation of the ChaCha20 stream cipher, which is an adaptation of Andy Polyakov's code for the kernel. Summary: - add fast vector/SIMD implementation of the ChaCha20 stream cipher, which mainly adapts Andy Polyakov's code for the kernel - add status attribute to AP queue device so users can easily figure out its status - fix race in page table release code, and and lots of documentation - remove uevent suppress from cio device driver, since it turned out that it generated more problems than it solved problems - quite a lot of virtual vs physical address confusion fixes - various other small improvements and cleanups all over the place" * tag 's390-5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (39 commits) s390/dasd: use default_groups in kobj_type s390/sclp_sd: use default_groups in kobj_type s390/pci: simplify __pciwb_mio() inline asm s390: remove unused TASK_SIZE_OF s390/crash_dump: fix virtual vs physical address handling s390/crypto: fix compile error for ChaCha20 module s390/mm: check 2KB-fragment page on release s390/mm: better annotate 2KB pagetable fragments handling s390/mm: fix 2KB pgtable release race s390/sclp: release SCLP early buffer after kernel initialization s390/nmi: disable interrupts on extended save area update s390/zcrypt: CCA control CPRB sending s390/disassembler: update opcode table s390/uv: fix memblock virtual vs physical address confusion s390/smp: fix memblock_phys_free() vs memblock_free() confusion s390/sclp: fix memblock_phys_free() vs memblock_free() confusion s390/exit: remove dead reference to do_exit from copy_thread s390/ap: add missing virt_to_phys address conversion s390/pgalloc: use pointers instead of unsigned long values s390/pgalloc: add virt/phys address handling to base asce functions ...

Pull ARM SoC devicetree updates from Arnd Bergmann: "As usual, this is the bulk of the updates for the SoC tree, adding more devices to existing files, addressing issues from ever improving automated checking, and fixing minor issues. The most interesting bits as usual are the new platforms. All the newly supported SoCs belong into existing families this time: - Qualcomm gets support for two newly announced platforms, both of which can now work in production environments: the SDX65 5G modem that can run a minimal Linux on its Cortex-A7 core, and the Snapdragon 8 Gen 1, their latest high-end phone SoC. - Renesas adds support for R-Car S4-8, the most recent automotive Server/Communication SoC. - TI adds support for J721s2, a new automotive SoC in the K3 family. - Mediatek MT7986a/b is a SoC used in Wifi routers, the latest generation following their popular MT76xx series. Only basic support is added for now. - NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8 series. - TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we have supported for a long time. New boards with the existing SoCs include - Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers - AT91/SAMA5 based evaluation board - NXP gains twenty new development and industrial boards for their i.MX and Layerscape SoCs - Intel IXP4xx now supports the final two machines in device tree that were previously only supported in old style board files. - Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while MT8183 is used in the Acer Chromebook 314. - Qualcomm gains support for the reference machines using the two new SoCs, plus a number of Chromebook variants and phones based on the Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia devices and the Microsoft Surface Duo 2. - ST STM32 now supports the Engicam i.Core STM32MP1 carrier board. - Tegra now boots various older Android devices based on 32-bit chips out of the box, including a number of ASUS Transformer tablets. There is also a new Jetson AGX Orin developer kit. - Apple support adds the missing device trees for all the remaining M1 Macbook and iMac variants, though not yet the M1 Pro/Max versions. - Allwinner now supports another version of the Tanix TX6 set-top box based on the H6 SoC. - Broadcom gains support for the Netgear RAXE500 Wireless router based on BCM4908" * tag 'dt-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (574 commits) Revert "ARM: dts: BCM5301X: define RTL8365MB switch on Asus RT-AC88U" arm64: dts: qcom: sm6125: Avoid using missing SM6125_VDDCX arm64: dts: qcom: sm8450-qrd: Enable USB nodes arm64: dts: qcom: sm8450: Add usb nodes ARM: dts: aspeed: add LCLK setting into LPC KCS nodes dt-bindings: ipmi: bt-bmc: add 'clocks' as a required property ARM: dts: aspeed: add LCLK setting into LPC IBT node ARM: dts: aspeed: p10: Add TPM device ARM: dts: aspeed: p10: Enable USB host ports ARM: dts: aspeed: Add TYAN S8036 BMC machine ARM: dts: aspeed: tyan-s7106: Add uart_routing and fix vuart config ARM: dts: aspeed: Adding Facebook Bletchley BMC ARM: dts: aspeed: g220a: Enable secondary flash ARM: dts: Add openbmc-flash-layout-64-alt.dtsi ARM: dts: aspeed: Add secure boot controller node dt-bindings: aspeed: Add Secure Boot Controller bindings ARM: dts: Remove "spidev" nodes dt-bindings: pinctrl: samsung: Add pin drive definitions for Exynos850 dt-bindings: arm: samsung: Document E850-96 board binding dt-bindings: Add vendor prefix for WinLink ...

Since irq request is the last thing in the driver probe, it happens later than the input device registration. This means that there is a small time window where if the open method is called the driver will attempt to enable not yet available irq. Fix that by moving the irq request before the input device registration.

This largely reverts commit 5a7b95fb. It breaks suspend with AMD GPUs, and we couldn't incrementally fix it. So, let's remove the code and go back to the drawing board. We keep the header extension to not break drivers already populating the regulator. We expect to re-add the code handling it soon.

This was detected on OpenSuSE Tumbleweed with libtraceevent-devel 1.3.0, as described by Jiri Slaby: ======================================================================= It breaks build with LIBTRACEEVENT_DYNAMIC and version 1.3.0: > util/debug.c: In function ‘perf_debug_option’: > util/debug.c:243:17: error: implicit declaration of function ‘tep_set_loglevel’ [-Werror=implicit-function-declaration] > 243 | tep_set_loglevel(TEP_LOG_INFO); > | ^~~~~~~~~~~~~~~~ > util/debug.c:243:34: error: ‘TEP_LOG_INFO’ undeclared (first use in this function); did you mean ‘TEP_PRINT_INFO’? > 243 | tep_set_loglevel(TEP_LOG_INFO); > | ^~~~~~~~~~~~ > | TEP_PRINT_INFO > util/debug.c:243:34: note: each undeclared identifier is reported only once for each function it appears in > util/debug.c:245:34: error: ‘TEP_LOG_DEBUG’ undeclared (first use in this function) > 245 | tep_set_loglevel(TEP_LOG_DEBUG); > | ^~~~~~~~~~~~~ > util/debug.c:247:34: error: ‘TEP_LOG_ALL’ undeclared (first use in this function) > 247 | tep_set_loglevel(TEP_LOG_ALL); > | ^~~~~~~~~~~ It is because the gcc's command line looks like: gcc ... -I/home/abuild/rpmbuild/BUILD/tools/lib/ ... -DLIBTRACEEVENT_VERSION=65790 ... ======================================================================= The proper way to fix this is more involved and so not suitable for this late in the 5.16-rc stage.

When running 'perf trace' with an BPF object like: # perf trace -e openat,tools/perf/examples/bpf/hello.c the event parsing eventually calls llvm__get_kbuild_opts() that runs a script and that ends up with SIGCHLD delivered to the 'perf trace' handler, which assumes the workload process is done and quits 'perf trace'. Move the SIGCHLD handler setup directly to trace__run(), where the event is parsed and the object is already compiled.

The PCI Write Barrier instruction ignores the registers encoded in it. There is thus no need to explicitly set the register to zero or to associate it with a variable at all.

cgroup process migration permission checks are performed at write time as whether a given operation is allowed or not is dependent on the content of the write - the PID. This currently uses current's cgroup namespace which is a potential security weakness as it may allow scenarios where a less privileged process tricks a more privileged one into writing into a fd that it created. This patch makes cgroup remember the cgroup namespace at the time of open and uses it for migration permission checks instad of current's. Note that this only applies to cgroup2 as cgroup1 doesn't have namespace support. This also fixes a use-after-free bug on cgroupns reported in https://lore.kernel.org/r/00000000000048c15c05d0083397@google.com Note that backporting this fix also requires the preceding patch.

of->priv is currently used by each interface file implementation to store private information. This patch collects the current two private data usages into struct cgroup_file_ctx which is allocated and freed by the common path. This allows generic private data which applies to multiple files, which will be used to in the following patch. Note that cgroup_procs iterator is now embedded as procs.iter in the new cgroup_file_ctx so that it doesn't need to be allocated and freed separately. v2: union dropped from cgroup_file_ctx and the procs iterator is embedded in cgroup_file_ctx as suggested by Linus. v3: Michal pointed out that cgroup1's procs pidlist uses of->priv too. Converted. Didn't change to embedded allocation as cgroup1 pidlists get stored for caching.
