+ * linux/byteorder_generic.h
+ * Generic Byte-reordering support
+ *
+ * Francois-Rene Rideau <rideau@ens.fr> 19970707
+ *    gathered all the good ideas from all asm-foo/byteorder.h into one file,
+ *    cleaned them up.
+ *    I hope it is compliant with non-GCC compilers.
+ *    I decided to put __BYTEORDER_HAS_U64__ in byteorder.h,
+ *    because I wasn't sure it would be ok to put it in types.h
+ *    Upgraded it to 2.1.43
+ * Francois-Rene Rideau <rideau@ens.fr> 19971012
+ *    Upgraded it to 2.1.57
+ *    to please Linus T., replaced huge #ifdef's between little/big endian
+ *    by nestedly #include'd files.
+ * Francois-Rene Rideau <rideau@ens.fr> 19971205
+ *    Made it to 2.1.71; now a facelift:
+ *    Put files under include/linux/byteorder/
+ *    Split swab from generic support.
+ *
+ * TODO:
+ *   = Regular kernel maintainers could also replace all these manual
+ *    byteswap macros that remain, disseminated among drivers,
+ *    after some grep or the sources...
+ *   = Linus might want to rename all these macros and files to fit his taste,
+ *    to fit his personal naming scheme.
+ *   = it seems that a few drivers would also appreciate
+ *    nybble swapping support...
+ *   = every architecture could add their byteswap macro in asm/byteorder.h
+ *    see how some architectures already do (i386, alpha, ppc, etc)
+ */
+
+/*
+ * The following macros are to be defined by <asm/byteorder.h>:
+ *
+ * Conversion of long and short int between network and host format
+ *	ntohl(__u32 x)
+ *	ntohs(__u16 x)
+ *	htonl(__u32 x)
+ *	htons(__u16 x)
+ * It seems that some programs (which? where? or perhaps a standard? POSIX?)
+ * might like the above to be functions, not macros (why?).
+ * if that's true, then detect them, and take measures.
+ * Anyway, the measure is: define only ___ntohl as a macro instead,
+ * and in a separate file, have
+ * unsigned long inline ntohl(x){return ___ntohl(x);}
+ *
+ * The same for constant arguments
+ *	__constant_ntohl(__u32 x)
+ *	__constant_ntohs(__u16 x)
+ *	__constant_htonl(__u32 x)
+ *	__constant_htons(__u16 x)
+ *
+ * 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
