If it's going to stay, then Intel should be able to provide simple tables
which give us the required information for a particular CPU model.

By sample table - does this mean we can map a throttle value in non-linear
scale to its percentage ?

Exactly. And that map should be provided by Intel simply because it's a
royal pain in the neck if users have to map random power of 2 values to
something useful. And of course every user has to do the same thing on
their own. That'd be more than silly.

Ok. Right now we dont have this capability on any SKUs, so i will just do a call to say get_throttle_map() for non_linear scale and fail if there is a nonlinear scale and later we can update to API to actually return the map for SKUs that support it.
