There are also new DT compatible strings for a couple of platforms, and thermal zones on some platforms will be registered as HWmon sensors now. Apart from the above, some drivers are updated (fixes mostly) and there is a new piece of documentation for the Intel DPTF (Dynamic Power and Thermal Framework) sysfs interface. Specifics: - Add a new thermal driver for the Intel Hardware Feedback Interface (HFI) including the HFI initialization, HFI notification interrupt handling and sending CPU capabilities change messages to user space via the thermal netlink interface (Ricardo Neri, Srinivas Pandruvada, Nathan Chancellor, Randy Dunlap). - Extend the intel-speed-select utility to handle out-of-band CPU configuration changes and add support for the CPU capabilities change messages sent over the thermal netlink interface by the new HFI thermal driver to it (Srinivas Pandruvada). - Convert the DT bindings to yaml format for the Exynos platform and fix and update the MAINTAINERS file for this driver (Krzysztof Kozlowski). - Register the thermal zones as HWmon sensors for the QCom's Tsens driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour). - Add the msm8953 compatible documentation in the bindings (Luca Weiss). - Add the sm8150 platform support to the QCom LMh driver's DT binding (Thara Gopinath). - Check the command result from the IPC command to the BPMP in the Tegra driver (Mikko Perttunen). - Silence the error for normal configuration where the interrupt is optionnal in the Broadcom thermal driver (Florian Fainelli). - Remove remaining dead code from the TI thermal driver (Yue Haibing). - Don't use bitmap_weight() in end_power_clamp() in the powerclamp driver (Yury Norov). - Update the OS policy capabilities handshake in the int340x thermal driver (Srinivas Pandruvada). - Increase the policies bitmap size in int340x (Srinivas Pandruvada). - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the int340x thermal driver (Rafael Wysocki). - Check for NULL after calling kmemdup() in int340x (Jiasheng Jiang). - Add Intel Dynamic Power and Thermal Framework (DPTF) kernel interface documentation (Srinivas Pandruvada). - Fix bullet list warning in the thermal documentation (Randy Dunlap)" * tag 'thermal-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (30 commits) thermal: int340x: Update OS policy capability handshake thermal: int340x: Increase bitmap size Documentation: thermal: DPTF Documentation MAINTAINERS: thermal: samsung: update Krzysztof Kozlowski's email thermal/drivers/ti-soc-thermal: Remove unused function ti_thermal_get_temp() thermal/drivers/brcmstb_thermal: Interrupt is optional thermal: tegra-bpmp: Handle errors in BPMP response drivers/thermal/ti-soc-thermal: Add hwmon support dt-bindings: thermal: tsens: Add msm8953 compatible dt-bindings: thermal: Add sm8150 compatible string for LMh thermal/drivers/qcom/lmh: Add support for sm8150 thermal/drivers/tsens: register thermal zones as hwmon sensors MAINTAINERS: thermal: samsung: Drop obsolete properties dt-bindings: thermal: samsung: Convert to dtschema tools/power/x86/intel-speed-select: v1.12 release tools/power/x86/intel-speed-select: HFI support tools/power/x86/intel-speed-select: OOB daemon mode thermal: intel: hfi: INTEL_HFI_THERMAL depends on NET thermal: netlink: Fix parameter type of thermal_genl_cpu_capability_event() stub thermal: Replace acpi_bus_get_device() ...

This notification type will allow user space to avoid running workloads on certain CPUs or proactively adjust power limits to avoid future events.

As result, applications compiled with the old version of struct smc_diag_linkinfo will receive garbage in struct smc_diag_lgrinfo.role if the kernel implements this new version of struct smc_diag_linkinfo. Fix this regression by reverting the part of commit 79d39fc503b4 that changes struct smc_diag_linkinfo. After all, there is SMC_GEN_NETLINK interface which is good enough, so there is probably no need to touch the smc_diag ABI in the first place.

Probing those, for example so that they can be passed to ARCH_REQ_XCOMP_GUEST_PERM, requires a new ioctl or arch_prctl. The latter is in fact worse, even though that is what the rest of the API uses, because it would require supported_xcr0 to be moved from the KVM module to the kernel just for this use. In addition, the value would be nonsensical (or an error would have to be returned) until the KVM module is loaded in. Therefore, to limit the growth of system ioctls, add a /dev/kvm variant of KVM_{GET,HAS}_DEVICE_ATTR, and implement it in x86 with just one group (0) and attribute (KVM_X86_XCOMP_GUEST_SUPP).

This new scheme set things up so that request_threaded_irq() is only called when a kernel wq type is being enabled. This also sets up for future interrupt request where different interrupt handler such as wq occupancy interrupt can be setup instead of the wq completion interrupt. Not calling request_irq() until the WQ actually needs an irq also prevents wasting of CPU irq vectors on x86 systems, which is a limited resource. idxd_flush_pending_descs() is moved to device.c since descriptor flushing is now part of wq disable rather than shutdown().

Also important is the e820 handling change on x86 that should work around PCI BAR allocation issues on some systems shipping since 2019. The rest is just a handful of assorted fixes and cleanups on top of the ACPI material merged previously. Specifics: - Add support for the the Platform Firmware Runtime Update and Telemetry (PFRUT) interface based on ACPI to allow certain pieces of the platform firmware to be updated without restarting the system and to provide a mechanism for collecting platform firmware telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang). - Ignore E820 reservations covering PCI host bridge windows on sufficiently recent x86 systems to avoid issues with allocating PCI BARs on systems where the E820 reservations cover the entire PCI host bridge memory window returned by the _CRS object in the system's ACPI tables (Hans de Goede). - Fix and clean up acpi_scan_init() (Rafael Wysocki). - Add more sanity checking to ACPI SPCR tables parsing (Mark Langsdorf). - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang). - Drop unnecessary "static" from the ACPI PCC address space handling driver added recently (kernel test robot)" * tag 'acpi-5.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: PCC: pcc_ctx can be static ACPI: scan: Rename label in acpi_scan_init() ACPI: scan: Simplify initialization of power and sleep buttons ACPI: scan: Change acpi_scan_init() return value type to void ACPI: SPCR: check if table->serial_port.access_width is too wide ACPI: APD: Check for NULL pointer after calling devm_ioremap() x86/PCI: Ignore E820 reservations for bridge windows on newer systems ACPI: pfr_telemetry: Fix info leak in pfrt_log_ioctl() ACPI: pfr_update: Fix return value check in pfru_write() ACPI: tools: Introduce utility for firmware updates/telemetry ACPI: Introduce Platform Firmware Runtime Telemetry driver ACPI: Introduce Platform Firmware Runtime Update device driver efi: Introduce EFI_FIRMWARE_MANAGEMENT_CAPSULE_HEADER and corresponding structures

Both PFRU and PFRT are based on ACPI _DSM interfaces located under special device objects in the ACPI Namespace, but these interfaces are different from each other, so it is better to provide a separate driver from each of them, even though they share some common definitions and naming conventions.
