2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds-14/+7
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-2/+2
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-29/+29
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-53/+55
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-1/+1
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.

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the temperature calibration data via SMC SIP calls. To prepare for supporting these SoCs, do the following changes. Rename rzg3e_thermal_parse_dt() to rzg3e_thermal_get_syscon_trim(). Move the syscon usage out of rzg3e_thermal_get_calibration() and into rzg3e_thermal_get_syscon_trim() and remove single-use variables from the private state. Place a pointer to rzg3e_thermal_get_syscon_trim() into the chip-specific struct, and use it in the probe function to retrieve the calibration values. Now that syscon usage has been moved out of rzg3e_thermal_get_calibration(), remove it and inline the calibration validation into the probe function. Also, reuse the TSU_CODE_MAX macro to mask the calibration values, as GEMASK(11, 0) and 0xFFF are equivalent, and replace the hardcoded 0xFFF with TSU_CODE_MAX in the calibration validation.

2026-01-07thermal: int340x: processor_thermal: Enable slow workload type hintsSrinivas Pandruvada-8/+49
On processors starting from Panther Lake, additional workload type hints are provided. The hardware analyzes workload residencies over an extended period to determine whether the workload classification tends toward idle/battery life states or sustained/performance states. Based on this long-term analysis, it classifies: Power Classification: If the workload exhibits more idle or battery life residencies, it is classified as "power". This is indicated by setting bit 4 of the current workload type. Performance Classification: If the workload exhibits more sustained or performance residencies, it is classified as "performance". This is indicated by clearing bit 4 of the current workload type. This approach enables applications to ignore short-term workload fluctuations and instead respond to longer-term power vs. performance trends. Hints of this type are called slow workload hints. To get notifications for slow workload hints, bit 22 in the thermal mailbox can be used for configuring workload interrupts. It is possible to exclusively enable slow workload hints or enable them in addition to the current workload hints. To enable slow workload hints, a new sysfs attribute is added to the existing workload hint attributes: workload_slow_hint_enable (RW): Write 1 to enable, 0 to disable. Reading this attribute shows the current state. This attribute is not present on any previous generation of processors.

The register layout differs from other chips, necessitating the creation of a dedicated file for this. This sensor provides a resolution of 1/64°C (6-bit fraction). For actual accuracy, refer to the datasheet, as it varies depending on the chip grade. Provide an interrupt for end of measurement and threshold violation and Contain temperature threshold comparators, in normal and secure address space, with direction and threshold programmability.

2025-11-21powercap: intel_rapl: Prepare read_raw() interface for atomic-context callersKuppuswamy Sathyanarayanan-1/+1
The current read_raw() implementation of the TPMI, MMIO and MSR interfaces does not distinguish between atomic and non-atomic callers. rapl_msr_read_raw() uses rdmsrq_safe_on_cpu(), which can sleep and issue cross CPU calls. When MSR-based RAPL PMU support is enabled, PMU event handlers can invoke this function from atomic context where sleeping or rescheduling is not allowed. In atomic context, the caller is already executing on the target CPU, so a direct rdmsrq() is sufficient. To support such usage, introduce an atomic flag to the read_raw() interface to allow callers pass the context information. Modify the common RAPL code to propagate this flag, and set the flag to reflect the calling contexts. Utilize the atomic flag in rapl_msr_read_raw() to perform direct MSR read with rdmsrq() when running in atomic context, and a sanity check to ensure target CPU matches the current CPU for such use cases. The TPMI and MMIO implementations do not require special atomic handling, so the flag is ignored in those paths. This is a preparatory patch for adding MSR-based RAPL PMU support.
