Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull ARM64 updates from Catalin Marinas: - KGDB support for arm64 - PCI I/O space extended to 16M (in preparation of PCIe support patches) - Dropping ZONE_DMA32 in favour of ZONE_DMA (we only need one for the time being), together with swiotlb late initialisation to correctly setup the bounce buffer - DMA API cache maintenance support (not all ARMv8 platforms have hardware cache coherency) - Crypto extensions advertising via ELF_HWCAP2 for compat user space - Perf support for dwarf unwinding in compat mode - asm/tlb.h converted to the generic mmu_gather code - asm-generic rwsem implementation - Code clean-up * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (42 commits) arm64: Remove pgprot_dmacoherent() arm64: Support DMA_ATTR_WRITE_COMBINE arm64: Implement custom mmap functions for dma mapping arm64: Fix __range_ok macro arm64: Fix duplicated Kconfig entries arm64: mm: Route pmd thp functions through pte equivalents arm64: rwsem: use asm-generic rwsem implementation asm-generic: rwsem: de-PPCify rwsem.h arm64: enable generic CPU feature modalias matching for this architecture arm64: smp: make local symbol static arm64: debug: make local symbols static ARM64: perf: support dwarf unwinding in compat mode ARM64: perf: add support for frame pointer unwinding in compat mode ARM64: perf: add support for perf registers API arm64: Add boot time configuration of Intermediate Physical Address size arm64: Do not synchronise I and D caches for special ptes arm64: Make DMA coherent and strongly ordered mappings not executable arm64: barriers: add dmb barrier arm64: topology: Implement basic CPU topology support arm64: advertise ARMv8 extensions to 32-bit compat ELF binaries ...
