To avoid some undesirable interactions between thermal zone suspend and resume with user space that is running when those operations are carried out, move them closer to the suspend and resume of devices, respectively, by updating dpm_prepare() to carry out thermal zone suspend and dpm_complete() to start thermal zone resume (that will continue asynchronously).

10 daysthermal: core: Drop redundant check from thermal_zone_device_update()Rafael J. Wysocki
Since __thermal_zone_device_update() checks if tz->state is TZ_STATE_READY and bails out immediately otherwise, it is not necessary to check the thermal_zone_is_present() return value in thermal_zone_device_update(). Namely, tz->state is equal to TZ_STATE_FLAG_INIT initially and that flag is only cleared in thermal_zone_init_complete() after adding tz to the list of thermal zones, and thermal_zone_exit() sets TZ_STATE_FLAG_EXIT in tz->state while removing tz from that list. Thus tz->state is not TZ_STATE_READY when tz is not in the list and the check mentioned above is redundant. Accordingly, drop the redundant thermal_zone_is_present() check from thermal_zone_device_update() and drop the former altogether because it has no more users. No intentional functional impact.

10 daysthermal: core: Free thermal zone ID later during removalRafael J. Wysocki
The thermal zone removal ordering is different from the thermal zone registration rollback path ordering and the former is arguably problematic because freeing a thermal zone ID prematurely may cause it to be used during the registration of another thermal zone which may fail as a result. Prevent that from occurring by changing the thermal zone removal ordering to reflect the thermal zone registration rollback path ordering. Also more the ida_destroy() call from thermal_zone_device_unregister() to thermal_release() for consistency.

10 daysthermal: core: Fix thermal zone governor cleanup issuesRafael J. Wysocki
If thermal_zone_device_register_with_trips() fails after adding a thermal governor to the thermal zone being registered, the governor is not removed from it as appropriate which may lead to a memory leak. In turn, thermal_zone_device_unregister() calls thermal_set_governor() without acquiring the thermal zone lock beforehand which may race with a governor update via sysfs and may lead to a use-after-free in that case. Address these issues by adding two thermal_set_governor() calls, one to thermal_release() to remove the governor from the given thermal zone, and one to the thermal zone registration error path to cover failures preceding the thermal zone device registration.

2026-04-01thermal: intel: int340x: processor: Move MMIO primitives to MMIO driverKuppuswamy Sathyanarayanan
MMIO-specific primitives differ from those used by the TPMI interface. The MSR and MMIO interfaces shared the same primitives in the common driver, but MMIO does not require many MSR-specific entries (like PSYS). Keeping these in the common driver does not add any value and requires interface-specific handling logic that makes the common layer unnecessarily complex. Move the MMIO primitive definitions and associated bitmasks into the MMIO interface driver. This change includes: 1. Add MMIO-local struct rapl_primitive_info instance without MSR-specific entries and assign it to priv->rpi during MMIO initialization. 2. Remove the RAPL MMIO case from rapl_config() in the common driver. No functional changes are intended.

2026-03-31thermal: core: Address thermal zone removal races with resumeRafael J. Wysocki
Since thermal_zone_pm_complete() and thermal_zone_device_resume() re-initialize the poll_queue delayed work for the given thermal zone, the cancel_delayed_work_sync() in thermal_zone_device_unregister() may miss some already running work items and the thermal zone may be freed prematurely [1]. There are two failing scenarios that both start with running thermal_pm_notify_complete() right before invoking thermal_zone_device_unregister() for one of the thermal zones. In the first scenario, there is a work item already running for the given thermal zone when thermal_pm_notify_complete() calls thermal_zone_pm_complete() for that thermal zone and it continues to run when thermal_zone_device_unregister() starts. Since the poll_queue delayed work has been re-initialized by thermal_pm_notify_complete(), the running work item will be missed by the cancel_delayed_work_sync() in thermal_zone_device_unregister() and if it continues to run past the freeing of the thermal zone object, a use-after-free will occur. In the second scenario, thermal_zone_device_resume() queued up by thermal_pm_notify_complete() runs right after the thermal_zone_exit() called by thermal_zone_device_unregister() has returned. The poll_queue delayed work is re-initialized by it before cancel_delayed_work_sync() is called by thermal_zone_device_unregister(), so it may continue to run after the freeing of the thermal zone object, which also leads to a use-after-free. Address the first failing scenario by ensuring that no thermal work items will be running when thermal_pm_notify_complete() is called. For this purpose, first move the cancel_delayed_work() call from thermal_zone_pm_complete() to thermal_zone_pm_prepare() to prevent new work from entering the workqueue going forward. Next, switch over to using a dedicated workqueue for thermal events and update the code in thermal_pm_notify() to flush that workqueue after thermal_pm_notify_prepare() has returned which will take care of all leftover thermal work already on the workqueue (that leftover work would do nothing useful anyway because all of the thermal zones have been flagged as suspended). The second failing scenario is addressed by adding a tz->state check to thermal_zone_device_resume() to prevent it from re-initializing the poll_queue delayed work if the thermal zone is going away. Note that the above changes will also facilitate relocating the suspend and resume of thermal zones closer to the suspend and resume of devices, respectively.

2026-03-05thermal: intel: int340x: processor: Move RAPL defaults to MMIO driverKuppuswamy Sathyanarayanan
Previously, the MMIO and MSR RAPL interfaces shared the same set of RAPL defaults provided by common code. However, unlike the MSR interface, the MMIO RAPL interface does not require CPU-specific variations in its default handling. Keeping the RAPL defaults in the RAPL common driver therefore provides no additional benefit. Move the MMIO defaults into the MMIO interface driver. This change includes the following updates: * Introduce a MMIO-local rapl_defaults instance with the appropriate default callbacks. * Assign the MMIO-specific rapl_defaults to priv->defaults during MMIO driver initialization. No functional changes are expected.

2026-03-05powercap: intel_rapl: Add a symbol namespace for intel_rapl exportsKuppuswamy Sathyanarayanan
Cleanup of the intel_rapl common driver requires introducing additional exported helper and lifecycle functions. Before adding new exports, create a dedicated symbol namespace for intel_rapl and update the relevant interface drivers to explicitly import it. This makes the intended usage of these symbols explicit, avoids polluting the global namespace, and prepares the codebase for the ongoing RAPL refactoring. No functional changes are intended.

2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21Convert 'alloc_flex' family to use the new default GFP_KERNEL argumentLinus Torvalds
This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2026-02-01thermal/qcom/lmh: Replace IRQF_ONESHOT with IRQF_NO_THREADSebastian Andrzej Siewior
Passing IRQF_ONESHOT ensures that the interrupt source is masked until the secondary (threaded) handler is done. If only a primary handler is used then the flag makes no sense because the interrupt can not fire (again) while its handler is running. The flag also prevents force-threading of the primary handler and the irq-core will warn about this. The intention here was probably to not allow forced-threading.

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the temperature calibration via SMC SIP and do not have a reset for the TSU peripheral, and use different minimum and maximum temperature values compared to the already supported RZ/G3E. Although the calibration data is stored in an OTP memory, the OTP itself is not memory-mapped, access to it is done through an OTP controller. The OTP controller is only accessible from the secure world, but the temperature calibration data stored in the OTP is exposed via SMC. Add support for retrieving the calibration data using arm_smcc_smc(). Add a compatible for RZ/T2H, RZ/N2H can use it as a fallback.
