The patch titled
i8k: make fan multiplier tunable with a module parameter
has been removed from the -mm tree. Its filename was
i8k-make-fan-multiplier-tunable-with-a-module-parameter.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: i8k: make fan multiplier tunable with a module parameter
From: Jochen Eisinger <jochen@xxxxxxxxxxxxxxxxxxx>
The i8k driver multiplies the fan speed reported by the BIOS with a factor of
30. On my Dell Latitude D800, this factor is not required.
I'd suggest to make this configurable.
