git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: "No major architecture features this time around, just some new HWCAP definitions, support for the Ampere SoC PMUs and a few fixes/cleanups. The bulk of the changes is reworking of the CPU capability checking code (cpus_have_cap() etc). - Major refactoring of the CPU capability detection logic resulting in the removal of the cpus_have_const_cap() function and migrating the code to "alternative" branches where possible - Backtrace/kgdb: use IPIs and pseudo-NMI - Perf and PMU: - Add support for Ampere SoC PMUs - Multi-DTC improvements for larger CMN configurations with multiple Debug & Trace Controllers - Rework the Arm CoreSight PMU driver to allow separate registration of vendor backend modules - Fixes: add missing MODULE_DEVICE_TABLE to the amlogic perf driver; use device_get_match_data() in the xgene driver; fix NULL pointer dereference in the hisi driver caused by calling cpuhp_state_remove_instance(); use-after-free in the hisi driver - HWCAP updates: - FEAT_SVE_B16B16 (BFloat16) - FEAT_LRCPC3 (release consistency model) - FEAT_LSE128 (128-bit atomic instructions) - SVE: remove a couple of pseudo registers from the cpufeature code. There is logic in place already to detect mismatched SVE features - Miscellaneous: - Reduce the default swiotlb size (currently 64MB) if no ZONE_DMA bouncing is needed. The buffer is still required for small kmalloc() buffers - Fix module PLT counting with !RANDOMIZE_BASE - Restrict CPU_BIG_ENDIAN to LLVM IAS 15.x or newer move synchronisation code out of the set_ptes() loop - More compact cpufeature displaying enabled cores - Kselftest updates for the new CPU features" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (83 commits) arm64: Restrict CPU_BIG_ENDIAN to GNU as or LLVM IAS 15.x or newer arm64: module: Fix PLT counting when CONFIG_RANDOMIZE_BASE=n arm64, irqchip/gic-v3, ACPI: Move MADT GICC enabled check into a helper perf: hisi: Fix use-after-free when register pmu fails drivers/perf: hisi_pcie: Initialize event->cpu only on success drivers/perf: hisi_pcie: Check the type first in pmu::event_init() arm64: cpufeature: Change DBM to display enabled cores arm64: cpufeature: Display the set of cores with a feature perf/arm-cmn: Enable per-DTC counter allocation perf/arm-cmn: Rework DTC counters (again) perf/arm-cmn: Fix DTC domain detection drivers: perf: arm_pmuv3: Drop some unused arguments from armv8_pmu_init() drivers: perf: arm_pmuv3: Read PMMIR_EL1 unconditionally drivers/perf: hisi: use cpuhp_state_remove_instance_nocalls() for hisi_hns3_pmu uninit process clocksource/drivers/arm_arch_timer: limit XGene-1 workaround arm64: Remove system_uses_lse_atomics() arm64: Mark the 'addr' argument to set_ptes() and __set_pte_at() as unused drivers/perf: xgene: Use device_get_match_data() perf/amlogic: add missing MODULE_DEVICE_TABLE arm64/mm: Hoist synchronization out of set_ptes() loop ...
