This patchset is to introduce coherent I/O memory barriers, which could be more efficient for coherent memory between I/O device and CPU, especially for ARMv8.
v4: * rename barriers to "coherent I/O memory barrier". * Make groups for various barriers in Doxygen doc. v3: * add more detailed comments about the new memory barriers. v2: * introduce DMA memory barriers.
