I've given some more thought on this over the weekend.

I completely agree with Dave's opinion now. He has a good understanding
of a long-term kernel development process (his opinions on ide were right
back in 2009 and 2005).

We keep support for hardware that has no active users "just in case" until
the maintenance cost becomes too high or it blocks (in major way) some new
developments. This is not the case with ide (even with all active users
ported to libata we will still be left with some support for hardware which
can no longer be tested) and it should stay unless some of above conditions
change. My personal wish to have coherent PATA support in the kernel doesn't
really matter here.

I would apologize for being wrong on this and I'm sorry for waisting
people's time.

Coming back to the pata_pcmcia patch, Tejun, please just ignore it. It is
now in mailing list's archives and this is sufficient to reference it if
ever needed.

Best regards,
