4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Lukasz Anaczkowski <lukasz.anaczkowski@xxxxxxxxx> commit 69cefc273f942bd7bb347a02e8b5b738d5f6e6f3 upstream. Scaling for Knights Landing is same as the default scaling (100000). When Knigts Landing support was added to the pstate driver, this parameter was omitted resulting in a kernel panic during boot.
