Tue, 10 Feb 2026 05:28:45 +0100

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linuxPull arm64 updates from Will Deacon: "There's a little less than normal, probably due to LPC & Christmas/New Year meaning that a few series weren't quite ready or reviewed in time. It's still useful across the board, despite the only real feature being support for the LS64 feature enabling 64-byte atomic accesses to endpoints that support it. ACPI: - Add interrupt signalling support to the AGDI handler - Add Catalin and myself to the arm64 ACPI MAINTAINERS entry CPU features: - Drop Kconfig options for PAN and LSE (these are detected at runtime) - Add support for 64-byte single-copy atomic instructions (LS64/LS64V) - Reduce MTE overhead when executing in the kernel on Ampere CPUs - Ensure POR_EL0 value exposed via ptrace is up-to-date - Fix error handling on GCS allocation failure CPU frequency: - Add CPU hotplug support to the FIE setup in the AMU driver Entry code: - Minor optimisations and cleanups to the syscall entry path - Preparatory rework for moving to the generic syscall entry code Hardware errata: - Work around Spectre-BHB on TSV110 processors - Work around broken CMO propagation on some systems with the SI-L1 interconnect Miscellaneous: - Disable branch profiling for arch/arm64/ to avoid issues with noinstr - Minor fixes and cleanups (kexec + ubsan, WARN_ONCE() instead of WARN_ON(), reduction of boolean expression) - Fix custom __READ_ONCE() implementation for LTO builds when operating on non-atomic types Perf and PMUs: - Support for CMN-600AE - Be stricter about supported hardware in the CMN driver - Support for DSU-110 and DSU-120 - Support for the cycles event in the DSU driver (alongside the dedicated cycles counter) - Use IRQF_NO_THREAD instead of IRQF_ONESHOT in the cxlpmu driver - Use !bitmap_empty() as a faster alternative to bitmap_weight() - Fix SPE error handling when failing to resume profiling Selftests: - Add support for the FORCE_TARGETS option to the arm64 kselftests - Avoid nolibc-specific my_syscall() function - Add basic test for the LS64 HWCAP - Extend fp-pidbench to cover additional workload patterns"* tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (43 commits) perf/arm-cmn: Reject unsupported hardware configurations perf: arm_spe: Properly set hw.state on failures arm64/gcs: Fix error handling in arch_set_shadow_stack_status() arm64: Fix non-atomic __READ_ONCE() with CONFIG_LTO=y arm64: poe: fix stale POR_EL0 values for ptrace kselftest/arm64: Raise default number of loops in fp-pidbench kselftest/arm64: Add a no-SVE loop after SVE in fp-pidbench perf/cxlpmu: Replace IRQF_ONESHOT with IRQF_NO_THREAD arm64: mte: Set TCMA1 whenever MTE is present in the kernel arm64/ptrace: Return early for ptrace_report_syscall_entry() error arm64/ptrace: Split report_syscall() arm64: Remove unused _TIF_WORK_MASK kselftest/arm64: Add missing file in .gitignore arm64: errata: Workaround for SI L1 downstream coherency issue kselftest/arm64: Add HWCAP test for FEAT_LS64 arm64: Add support for FEAT_{LS64, LS64_V} KVM: arm64: Enable FEAT_{LS64, LS64_V} in the supported guest arm64: Provide basic EL2 setup for FEAT_{LS64, LS64_V} usage at EL0/1 KVM: arm64: Handle DABT caused by LS64* instructions on unsupported memory KVM: arm64: Add documentation for KVM_EXIT_ARM_LDST64B ...

f22c81bebf8bda6e54dc132df0ed54f6bf8756f9 - arm64: Disable branch profiling for all arm64 code

Tue, 06 Jan 2026 11:16:35 +0100

arm64: Disable branch profiling for all arm64 codeThe arm64 kernel doesn't boot with annotated branches(PROFILE_ANNOTATED_BRANCHES) enabled and CONFIG_DEBUG_VIRTUAL together.Bisecting it, I found that disabling branch profiling in arch/arm64/mmsolved the problem. Narrowing down a bit further, I found thatphysaddr.c is the file that needs to have branch profiling disabled toget the machine to boot.I suspect that it might invoke some ftrace helper very early in the bootprocess and ftrace is still not enabled(!?).Rather than playing whack-a-mole with individual files, disable branchprofiling for the entire arch/arm64 tree, similar to what x86 alreadydoes in arch/x86/Kbuild.Cc: stable@vger.kernel.orgSigned-off-by: Breno Leitao Acked-by: Mark Rutland Signed-off-by: Will Deacon List of files: /linux/arch/arm64/Kbuild
