578  * I hope it is compliant with non-GCC compilers.
579  * I decided to put __BYTEORDER_HAS_U64__ in byteorder.h,
580  * because I wasn't sure it would be ok to put it in types.h
581  * Upgraded it to 2.1.43
582  * Francois-Rene Rideau <fare@tunes.org> 19971012
583  * Upgraded it to 2.1.57
584  * to please Linus T., replaced huge #ifdef's between little/big endian
585  * by nestedly #include'd files.
586  * Francois-Rene Rideau <fare@tunes.org> 19971205
587  * Made it to 2.1.71; now a facelift:
588  * Put files under include/linux/byteorder/
589  * Split swab from generic support.
590  *
591  * TODO:
592  * = Regular kernel maintainers could also replace all these manual
593  * byteswap macros that remain, disseminated among drivers,
594  * after some grep or the sources...
595  * = Linus might want to rename all these macros and files to fit his taste,
596  * to fit his personal naming scheme.
597  * = it seems that a few drivers would also appreciate
598  * nybble swapping support...
599  * = every architecture could add their byteswap macro in asm/byteorder.h
600  * see how some architectures already do (i386, alpha, ppc, etc)
601  * = cpu_to_beXX and beXX_to_cpu might some day need to be well
602  * distinguished throughout the kernel. This is not the case currently,
603  * since little endian, big endian, and pdp endian machines needn't it.
