- * Generic Byte-reordering support

- * The "... p" macros, like le64_to_cpup, can be used with pointers
- * to unaligned data, but there will be a performance penalty on
- * some architectures. Use get_unaligned for unaligned data.
- *
- * The following macros are to be defined by <asm/byteorder.h>:
- *
- * Conversion of XX-bit integers (16- 32- or 64-)
- * between native CPU format and little/big endian format
- * 64-bit stuff only defined for proper architectures
- * cpu_to_[bl]eXX(__uXX x)
- * [bl]eXX_to_cpu(__uXX x)
- *
- * The same, but takes a pointer to the value to convert
- * cpu_to_[bl]eXXp(__uXX x)
- * [bl]eXX_to_cpup(__uXX x)
- *
- * The same, but change in situ
- * cpu_to_[bl]eXXs(__uXX x)
- * [bl]eXX_to_cpus(__uXX x)
- *
- * See asm-foo/byteorder.h for examples of how to provide
- * architecture-optimized versions
