/*
 * 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
