Release 4.12 include/uapi/asm-generic/swab.h



#include <asm/bitsperlong.h>

 * 32 bit architectures typically (but not always) want to
 * set __SWAB_64_THRU_32__. In user space, this is only
 * valid if the compiler supports 64 bit data types.

#if __BITS_PER_LONG == 32
#if defined(__GNUC__) && !defined(__STRICT_ANSI__) || defined(__KERNEL__)

#define __SWAB_64_THRU_32__

#endif /* _ASM_GENERIC_SWAB_H */
