I'm not a fan of this change, because the new argument will only be needed in one place where intel_pstate_get_hwp_max() and it requires adding redundant local vars and pointless updates elsewhere. Besides, in intel_pstate_get_cpu_pstates() you can do something like this after calling intel_pstate_get_hwp_max(): cpu->pstate.max_pstate = HWP_GUARANTEED_PERF(READ_ONCE(cpu->hwp_cap_cached)); cpu->pstate.max_freq = cpu->pstate.max_pstate * cpu->pstate.scaling;
