So, while I'm generally in favor of moving this code over to samples/,
I'm a bit nervous about a single, do-it-all patch.  I'd rather see each
subsystem's stuff moved separately, with (1) review from the appropriate
maintainer, and (2) some sense that somebody has looked at this code and
ensured that it still makes sense to keep around.

For example, pcmcia/crc32hash.c predates the git era and has only seen
trivial changes in living memory.  I have this vague sense that the
number of new PCMCIA cards needing addition is pretty small these days.
Rather than move it to samples/ (what is it a sample of?), we might want
to consider just getting rid of it.

Thanks,
