Subject: [Patch 0/2] Add support for _TFP and configurable throttle pctg
This patch set adds support for two features to get a finer control
over the impact of Thermal Throttling on performance.
1) Patch 1: Adds support to read Thermal fast Sampling Period (_TFP)
ACPI object and use it over "Thermal Sampling Period (_TSP)" for
Passive cooling if both are present.
2) Patch 2: Adds support to configure the CPUFREQ reduction percentage
and not always cause throttling in steps of "20%".
Both patches can be applied independently.
