Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

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
