Rafael J. Wysocki 96f9abc918 cpufreq: intel_pstate: Clear HWP desired on suspend/shutdown and offline ... [ Upstream commit dbea75fe18 ] Commit a365ab6b9d ("cpufreq: intel_pstate: Implement the ->adjust_perf() callback") caused intel_pstate to use nonzero HWP desired values in certain usage scenarios, but it did not prevent them from being leaked into the confugirations in which HWP desired is expected to be 0. The failing scenarios are switching the driver from the passive mode to the active mode and starting a new kernel via kexec() while intel_pstate is running in the passive mode. To address this issue, ensure that HWP desired will be cleared on offline and suspend/shutdown.
