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,
