What is in include/asm-generic/io.h? $ git grep iowrite64be | grep generic include/asm-generic/io.h:#ifndef iowrite64be include/asm-generic/io.h:#define iowrite64be iowrite64be include/asm-generic/io.h:static inline void iowrite64be(u64 value, volatile void __iomem *addr) include/asm-generic/iomap.h:extern void iowrite64be(u64, void __iomem *); so are you sure this is needed? What code is failing to build for you? thanks, greg k-h
