Pull arm64 updates from Catalin Marinas: - kdump support, including two necessary memblock additions: memblock_clear_nomap() and memblock_cap_memory_range() - ARMv8.3 HWCAP bits for JavaScript conversion instructions, complex numbers and weaker release consistency - arm64 ACPI platform MSI support - arm perf updates: ACPI PMU support, L3 cache PMU in some Qualcomm SoCs, Cortex-A53 L2 cache events and DTLB refills, MAINTAINERS update for DT perf bindings - architected timer errata framework (the arch/arm64 changes only) - support for DMA_ATTR_FORCE_CONTIGUOUS in the arm64 iommu DMA API - arm64 KVM refactoring to use common system register definitions - remove support for ASID-tagged VIVT I-cache (no ARMv8 implementation using it and deprecated in the architecture) together with some I-cache handling clean-up - PE/COFF EFI header clean-up/hardening - define BUG() instruction without CONFIG_BUG * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (92 commits) arm64: Fix the DMA mmap and get_sgtable API with DMA_ATTR_FORCE_CONTIGUOUS arm64: Print DT machine model in setup_machine_fdt() arm64: pmu: Wire-up Cortex A53 L2 cache events and DTLB refills arm64: module: split core and init PLT sections arm64: pmuv3: handle pmuv3+ arm64: Add CNTFRQ_EL0 trap handler arm64: Silence spurious kbuild warning on menuconfig arm64: pmuv3: use arm_pmu ACPI framework arm64: pmuv3: handle !PMUv3 when probing drivers/perf: arm_pmu: add ACPI framework arm64: add function to get a cpu's MADT GICC table drivers/perf: arm_pmu: split out platform device probe logic drivers/perf: arm_pmu: move irq request/free into probe drivers/perf: arm_pmu: split cpu-local irq request/free drivers/perf: arm_pmu: rename irq request/free functions drivers/perf: arm_pmu: handle no platform_device drivers/perf: arm_pmu: simplify cpu_pmu_request_irqs() drivers/perf: arm_pmu: factor out pmu registration drivers/perf: arm_pmu: fold init into alloc drivers/perf: arm_pmu: define armpmu_init_fn ...
