Machines that support SoC Slider largely use it instead of EPP, which may continue to exist in a diminished role, or vanish entirely.

Check that the driver actually registered the profile named "SoC Slider" before reading or writing these modparams. n.b. This utility allows writing the Slider and Offset modparams even if the driver policy is not "balanced". Currently the processor_thermal_soc_slider consults those modparams only in "balanced" mode.

This was due to how set_thread_siblings() parsed the sibling-bit-mask. Update set_thread_siblings to instead parse the sibling-list, like other cpu lists, and to thus order HT siblings by ascending CPU number, no matter the size of the system.
