From: Arnd Bergmann <arnd@xxxxxxxx> In previous kernels, there were conflicting definitions for what ioread64_lo_hi() and similar functions were supposed to do on architectures with native 64-bit MMIO. Based on the actual usage in drivers, they are in fact expected to be a pair of 32-bit accesses on all architectures, which makes the powerpc64 definition wrong. Remove it and use the generic implementation instead. Drivers that want to have split lo/hi or hi/lo accesses on 32-bit architectures but can use 64-bit accesses where supported should instead use ioread64()/iowrite64() after including the corresponding header file.
