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
