That's because certain configurations, where this shows up, like !

extremely weird configs for most modern HW and distributions.
I'm not saying we can't fix the problem with tools or that we can't
invest huge amounts of time patching and fixing this. I am saying we
should be questioning the value of the investment in doing so.
I also claim that getting rid of the __dev.* sectional attributes (for
which I've already submitted a small patch) fixes 90% of the problems
(since they're mainly caused by driver writers not understanding what
all of these things mean). The remaining ones are clearer and
additionally, show up on every build (whether HOTPLUG or not).
Before we start to pillory driver writers for not caring about configs
they rightly don't give a toss about, could we at least get someone
(anyone!) in the community that cares about extreme low memory
configurations to give us reasons why there's value to all this effort
(rather than spending it on say reducing cache footprints or eliminating
space in structures)? All the people I've asked so far (mainly in arm,
admittedly) have said they have bigger things to worry about.
