*I* am too lazy? I am doing all the work. Nobody else is doing
anything about it.

Linux is throttling the CPU speed of this machine without trying to to
increase the fan speed first, that is not ideal.

So I do the first step of writing the fan driver and I get told it
shouldn't be a separate driver, it should be part of wmi, only to be
told later by the same person that it doesn't belong in wmi when I put
it there. Then I get told virt_to_physical() is not good, and it
should move to staging, and then I'm told you don't want it.

And at no point in time has anybody helped an iota to actually solve
the throttling problem.

So much for collaborative effort.

Forget it, I was hoping other people could use the driver while
somebody explains to me how to plug it o the thermal framework so it
gets activated when the machine gets hot, but clearly that's not going
to happen.

I have done my fair share of collaboration.

I'll just keep the driver for myself and figure out how to solve the
throttling by myself, which apparently I have to do anyway.

Cheers.
