The paride drivers are some of the cruftiest, grottiest block drivers
(besides drivers/ide and floppy.c) and have seen one single targeted
commit since the dawn of git in 2007.  Drop them to make block layer
improvements easier.

This will make my parallel port ZIP and LS-120 drives useless :(

So you are still using them and the code actually works properly?

I don't use them daily, only occasionally. Last time they worked.
Checked now and it seems to work:
