* Split swab from generic support.
*

* = 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.
