These use CONFIG_RAW_MEMCPY_IO to determine whether an arch should use the generic __raw_memcpy_toio32 routine or its own specialised version. We provide a specialised implementation for x86_64. These patches should apply cleanly against current -git, and have been tested on i386 and x86_64. The patch series is as follows: raw_memcpy_io.patch Introduce the generic MMIO 32-bit copy routine. x86_64-memcpy32.patch Add memcpy32 routine to x86_64. arch-specific-raw_memcpy_io.patch Get each arch to use generic memcpy_io code, except x86_64, which uses memcpy32.
