This patch adds new function i8k_get_fan_nominal_speed() for
doing SMM call which will return nominal fan RPM for
specified fan speed. It returns nominal RPM value at which
fan operate when speed (0, 1, 2, 3) is set. It looks like
RPM value is not accurate, but still provides very useful
information.
First it can be used to validate if certain fan speed could
be accepted by SMM for setting fan speed and we can use
this routine to detect maximal fan speed.
Second it returns RPM value, so we can check if value looks
correct with multiplier 30 or multiplier 1 (until now only
these two multiplier were used). If RPM value with
multiplier 30 is too high, then multiplier 1 is used.
In case when SMM reports that new function is not supported
we will fallback to old hardcoded values. Maximal fan speed
would be 2 and RPM multiplier 30.

Tested-by the submitter is kind of implied.
Anyway, this patch does not apply to 3.19-rc1, nor to 3.18.
What is your baseline ? Can you rebase to 3.19-rc1 ?
Or do I need to apply some other patch first ?
Thanks,
Guenter
You need to apply these old patches:
i8k: Add support for temperature sensor labels
i8k: Register only temperature sensors which have labels
i8k: Return -ENODATA for invalid temperature
i8k: Rework error retries
