Public bug reported:
"Commit a365ab6b9dfb ("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"
I believe I'm seeing this issue on my laptop during suspend/resume. The
upstream fix is:
commit dbea75fe18f60e364de6d994fc938a24ba249d81
