Hi Florian,

I love your patch! Perhaps something to improve:

[auto build test WARNING on net-next/master]

^1da177e Linus Torvalds 2005-04-16 25 * Made it to 2.1.71; now a facelift:
^1da177e Linus Torvalds 2005-04-16 26 * Put files under include/linux/byteorder/
^1da177e Linus Torvalds 2005-04-16 27 * Split swab from generic support.
^1da177e Linus Torvalds 2005-04-16 28 *
^1da177e Linus Torvalds 2005-04-16 29 * TODO:
^1da177e Linus Torvalds 2005-04-16 30 * = Regular kernel maintainers could also replace all these manual
^1da177e Linus Torvalds 2005-04-16 31 * byteswap macros that remain, disseminated among drivers,
^1da177e Linus Torvalds 2005-04-16 32 * after some grep or the sources...
^1da177e Linus Torvalds 2005-04-16 33 * = Linus might want to rename all these macros and files to fit his taste,
^1da177e Linus Torvalds 2005-04-16 34 * to fit his personal naming scheme.
^1da177e Linus Torvalds 2005-04-16 35 * = it seems that a few drivers would also appreciate
^1da177e Linus Torvalds 2005-04-16 36 * nybble swapping support...
^1da177e Linus Torvalds 2005-04-16 37 * = every architecture could add their byteswap macro in asm/byteorder.h
^1da177e Linus Torvalds 2005-04-16 38 * see how some architectures already do (i386, alpha, ppc, etc)
^1da177e Linus Torvalds 2005-04-16 39 * = cpu_to_beXX and beXX_to_cpu might some day need to be well
^1da177e Linus Torvalds 2005-04-16 40 * distinguished throughout the kernel. This is not the case currently,
^1da177e Linus Torvalds 2005-04-16 41 * since little endian, big endian, and pdp endian machines needn't it.
^1da177e Linus Torvalds 2005-04-16 42 * But this might be the case for, say, a port of Linux to 20/21 bit
^1da177e Linus Torvalds 2005-04-16 43 * architectures (and F21 Linux addict around?).
