I'd be fine with either way. As long as it disables the blinking cursor.

Well, all I need is a way to disable the cursor at boot time, as we
don't want it to be in our boot screen on a embedded system. It is not
only ruin the aesthetics but also gives the wrong assumption that the
system awaits input. There is no userspace at this point, so that's no
option.

My first approach was adding a __setup variable to select that, but it
wasn't beloved by the people get_maintainer.pl spit out. So I made it
compile-time definable, and Clemens extended that to a more powerful
interface of settings.

I don't really have a strong opinion on which way to go, all I need is a
cursor-free system startup :) And I would of course prefer that patch to
be in mainline.
