- * linux/byteorder_generic.h
- * 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.
- *
- * Francois-Rene Rideau <fare@...es.org> 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 <fare@...es.org> 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 <fare@...es.org> 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)
- *   = cpu_to_beXX and beXX_to_cpu might some day need to be well
- *    distinguished throughout the kernel. This is not the case currently,
- *    since little endian, big endian, and pdp endian machines needn't it.
- *    But this might be the case for, say, a port of Linux to 20/21 bit
- *    architectures (and F21 Linux addict around?).

- * 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 of all the swab functions
- *    (including the s and p versions).  These can be defined in
- *    asm-arch/byteorder.h.  Any which are not, are defined here.
- *    __arch__swabXXs() is defined in terms of __arch__swabXXp(), which
- *    is defined in terms of __arch__swabXX(), which is in turn defined
- *    in terms of ___swabXX(x).
- *    These must be macros.  They may be unsafe for arguments with
- *    side-effects.
- *
- * __fswabXX
- *    Inline function versions of the __arch__ macros.  These _are_ safe
- *    if the arguments have side-effects.  Note there are no s and p
- *    versions of these.
- *
- * __swabXX[sb]
- *    There are the ones you should actually use.  The __swabXX versions
- *    will be a constant given a constant argument and use the arch
- *    specific code (if any) for non-constant arguments.  The s and p
- *    versions always use the arch specific code (constant folding
- *    doesn't apply).  They are safe to use with arguments with
- *    side-effects.
- *
- * swabXX[sb]
- *    Nicknames for __swabXX[sb] to use in the kernel.
