Add thermal zone support by making use of the thermistor SYS_THERM6.
Based on experiments, this thermistor seems to reflect the actual
surface temperature of the laptop.

For the cooling device, all BIG CPU cores are throttle down to keep the
temperature at a sane level.

Is it okay to let the 4xA78C run at full throttle in thermal emergencies though?

Ouch, I didn't know we were serving burnt fingers at the cafeteria today :D

Or maybe this just looks scary.. The laptop looks plastic, so maybe it won't cause instant
burns?

Disclaimer: I'm an end user that likes to cosplay as a kernel
developer sometimes...

IMO, it just looks scary.  the skin-temp, afaik, is the temperature of
the shell of the laptop, so once it reaches 73C, it would be crit.  In
practice (I've been testing this patch set for a while), I've never
been able to hit 73C, even with the ambient temperature in my
apartment being 77F and multiple compilations running.  I've also
tested a hack to increase the trips to a little bit higher (65/68/73)
and still not been able to do so.

On the flip side, without this patchset, we do not have any thermal
trips at all, and the machine will quite happily run up to 90C (and
I've not seen it shut down, but I wouldn't use it on my lap when this
is occurring...)

I don't get it. Can you elaborate?

73c is what the reasonable number I came up with after some experiments. At
this point the temperature won't burn your finger but crossing this surely
would (that's what happening without this series).

8280xp has 4xA78C and 4xX1C. You only added the latter ones to the 
cooling map.

Right, that's because the first 4 cores doesn't contribute to thermal much and
thottling them doesn't yield any thermal gain.
