    Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux · 1ce235fa
    Linus Torvalds authored
    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
