  "message": "cpufreq: Make cpufreq_update_pressure() fall back to cpuinfo.max_freq\n\nIf arch_scale_freq_ref() is not defined for a given arch (like x86, for\nexample), cpufreq_update_pressure() will always set cpufreq_pressure to\nzero for all CPUs in the system, which is generally problematic on\nsystems with asymmetric capacity [1].\n\nHowever, in the absence of arch_scale_freq_ref(), it is reasonable\nto assume that cpuinfo.max_freq is the maximum sustainable frequency\nfor the given cpufreq policy.  Moreover, there are cases in which\narch_scale_freq_ref() would need to be defined to return essentially\nthe cpuinfo.max_freq value anyway (for example, intel_pstate on\nhybrid platforms).\n\nFor the above reasons, update cpufreq_update_pressure() to fall back to\nusing cpuinfo.max_freq as the reference frequency if zero is returned by\narch_scale_freq_ref().\n\nFixes: 75d659317bb1 (\"cpufreq: Add a cpufreq pressure feedback for the scheduler\")\nLink: https://lore.kernel.org/lkml/CAKfTPtBuRLfYNnR4w--cFZYZy-R8gaPEgVwCcaMmbCcJ2H-muQ@mail.gmail.com/ [1]\nSigned-off-by: Rafael J.
