e2a002b9a7 [PATCH] powerpc: Fix windfarm_pm112 not starting all control loops
This adds a couple of printk's to windfarm_pm112 to display which
control loops are actually starting and fixes a bug where it would not
start all loops.

b55fafc5a8 [PATCH] powerpc: Fix old g5 issues with windfarm
Some of the windfarm sensor modules can initialize on old machines that
don't have full windfarm support like non-dual core desktop G5s.
Unfortunately, by doing so, they would trigger a bug in their matching
algorithm causing them to attach to the wrong bus, thus triggering
issues with the i2c core and breaking the thermal driver.

This patch fixes the probing issue (so that they will work when a
windfarm port is done to these machines) and also prevents for now
windfarm to load at all on these machines that still use therm_pm72 to
avoid wasting resources.

ac171c4666 [PATCH] powerpc: Thermal control for dual core G5s
This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
(both 2 and 4 core models), keeping the machine from getting into
vacuum-cleaner mode ;) For proper credits, the patch was initially
written by Paul Mackerras, and slightly reworked by me to add overtemp
handling among others. The patch also removes the sysfs attributes from
windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
core to automagically expose attributes for sensor & controls.
