  arm64: Remove pgprot_dmacoherent() (2014-03-24 10:35:35 +0000)

----------------------------------------------------------------
- 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

----------------------------------------------------------------
