Yes, Sebastian overlooked that post.
What should we do now?

* ~ 12 drivers are affected.
* "*start = page + (begin-off)" is very common, most proc functions use
that
* I tried your patch, "dd bs=1" and "dd bs=1024" doesn't match.
* quite many proc functions don't support "bs=1" properly.

the overhead is negligible. IMHO we should do that.
