When cross compiling the kernel with clang, we need to override CLANG_CROSS_FLAGS when preparing the step libraries. Prior to commit d1d096312176 ("tools: fix annoying "mkdir -p ..." logs when building tools in parallel"), MAKEFLAGS would have been set to a value that wouldn't set a value for CLANG_CROSS_FLAGS, hiding the fact that we weren't properly overriding it.

2025-06-10pinctrl: sunxi: dt: Consider pin base when calculating bank number from pinChen-Yu Tsai
In prepare_function_table() when the pinctrl function table IRQ entries are generated, the pin bank is calculated from the absolute pin number; however the IRQ bank mux array is indexed from the first pin bank of the controller. For R_PIO controllers, this means the absolute pin bank is way off from the relative pin bank used for array indexing. Correct this by taking into account the pin base of the controller.

2025-06-09ARC: Replace __ASSEMBLY__ with __ASSEMBLER__ in the non-uapi headersThomas Huth
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize on the __ASSEMBLER__ macro that is provided by the compilers now. This is a completely mechanical patch (done with a simple "sed -i" statement).

2025-06-09ARC: unwind: Use built-in sort swap to reduce code size and improve performanceYu-Chun Lin
The custom swap function used in sort() was identical to the default built-in sort swap. Remove the custom swap function and passes NULL to sort(), allowing it to use the default swap function. This change reduces code size and improves performance, particularly when CONFIG_MITIGATION_RETPOLINE is enabled. With RETPOLINE mitigation, indirect function calls incur significant overhead, and using the default swap function avoids this cost. $ ./scripts/bloat-o-meter ./unwind.o.old ./unwind.o.new add/remove: 0/1 grow/shrink: 0/1 up/down: 0/-22 (-22) Function old new delta init_unwind_hdr.constprop 544 540 -4 swap_eh_frame_hdr_table_entries 18 - -18 Total: Before=4410, After=4388, chg -0.50% Signed-off-by: Yu-Chun Lin <eleanor15x@gmail.com> Signed-off-by: Vineet Gupta <vgupta@kernel.org>
2025-06-09ARC: atomics: Implement arch_atomic64_cmpxchg using _relaxedJason Gunthorpe
The core atomic code has a number of macros where it elaborates architecture primitives into more functions. ARC uses arch_atomic64_cmpxchg() as it's architecture primitive which disable alot of the additional functions. Instead provide arch_cmpxchg64_relaxed() as the primitive and rely on the core macros to create arch_cmpxchg64(). The macros will also provide other functions, for instance, try_cmpxchg64_release(), giving a more complete implementation.

2025-06-08tools/power turbostat: Avoid probing the same perf countersZhang Rui
For the RAPL package energy status counter, Intel and AMD share the same perf_subsys and perf_name, but with different MSR addresses. Both rapl_counter_arch_infos[0] and rapl_counter_arch_infos[1] are introduced to describe this counter for different Vendors. As a result, the perf counter is probed twice, and causes a failure in in get_rapl_counters() because expected_read_size and actual_read_size don't match. Fix the problem by skipping the already probed counter. Note, this is not a perfect fix. For example, if different vendors/platforms use the same MSR value for different purpose, the code can be fooled when it probes a rapl_counter_arch_infos[] entry that does not belong to the running Vendor/Platform. In a long run, better to put rapl_counter_arch_infos[] into the platform_features so that this becomes Vendor/Platform specific.

2025-06-08tools/power turbostat: Allow probing RAPL with platform_features->rapl_msrs ↵Zhang Rui
cleared platform_features->rapl_msrs describes the RAPL MSRs supported. While RAPL Perf counters can be exposed from different kernel backend drivers, e.g. RAPL MSR I/F driver, or RAPL TPMI I/F driver. Thus, turbostat should first blindly probe all the available RAPL Perf counters, and falls back to the RAPL MSR counters if they are listed in platform_features->rapl_msrs. With this, platforms that don't have RAPL MSRs can clear the platform_features->rapl_msrs bits and use RAPL Perf counters only.

2025-06-08tools/power turbostat: Fix AMD package-energy reportingGautham R. Shenoy
commit 05a2f07db888 ("tools/power turbostat: read RAPL counters via perf") that adds support to read RAPL counters via perf defines the notion of a RAPL domain_id which is set to physical_core_id on platforms which support per_core_rapl counters (Eg: AMD processors Family 17h onwards) and is set to the physical_package_id on all the other platforms. However, the physical_core_id is only unique within a package and on platforms with multiple packages more than one core can have the same physical_core_id and thus the same domain_id. (For eg, the first cores of each package have the physical_core_id = 0). This results in all these cores with the same physical_core_id using the same entry in the rapl_counter_info_perdomain[]. Since rapl_perf_init() skips the perf-initialization for cores whose domain_ids have already been visited, cores that have the same physical_core_id always read the perf file corresponding to the physical_core_id of the first package and thus the package-energy is incorrectly reported to be the same value for different packages. Note: This issue only arises when RAPL counters are read via perf and not when they are read via MSRs since in the latter case the MSRs are read separately on each core. Fix this issue by associating each CPU with rapl_core_id which is unique across all the packages in the system.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 perf fix from Thomas Gleixner: "A single fix for the x86 performance counters on Intel CPUs: The MSR offset calculations for fixed performance counters are stored at the wrong index in the configuration array causing the general purpose counter MSR offset to be overwritten, so both the general purpose and the fixed counters offsets are incorrect. Correct the array index calculation to fix that" * tag 'perf-urgent-2025-06-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/intel: Fix incorrect MSR index calculations in intel_pmu_config_acr()

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq fix from Thomas Gleixner: "A single fix for the PCI/MSI code: The conversion to per device MSI domains created a MSI domain with size 1 instead of sizing it to the maximum possible number of MSI interrupts for the device. This "worked" as the subsequent allocations resized the domain, but the recent change to move the prepare() call into the domain creation path broke this works by chance mechanism. Size the domain properly at creation time" * tag 'irq-urgent-2025-06-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: PCI/MSI: Size device MSI domain with the maximum number of vectors

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull more tracing fixes from Steven Rostedt: - Fix regression of waiting a long time on updating trace event filters When the faultable trace points were added, it needed task trace RCU synchronization. This was added to the tracepoint_synchronize_unregister() function. The filter logic always called this function whenever it updated the trace event filters before freeing the old filters. This increased the time of "trace-cmd record" from taking 13 seconds to running over 2 minutes to complete. Move the freeing of the filters to call_rcu*() logic, which brings the time back down to 13 seconds. - Fix ring_buffer_subbuf_order_set() error path lock protection The error path of the ring_buffer_subbuf_order_set() released the mutex too early and allowed subsequent accesses to setting the subbuffer size to corrupt the data and cause a bug. By moving the mutex locking to the end of the error path, it prevents the reentrant access to the critical data and also allows the function to convert the taking of the mutex over to the guard() logic. - Remove unused power management clock events The clock events were added in 2010 for power management. In 2011 arm used them. In 2013 the code they were used in was removed. These events have been wasting memory since then. - Fix sparse warnings There was a few places that sparse warned about trace_events_filter.c where file->filter was referenced directly, but it is annotated with an __rcu tag. Use the helper functions and fix them up to use rcu_dereference() properly. * tag 'trace-v6.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Add rcu annotation around file->filter accesses tracing: PM: Remove unused clock events ring-buffer: Fix buffer locking in ring_buffer_subbuf_order_set() tracing: Fix regression of filter waiting a long time on RCU synchronization
