From 7673c8a4c75d1cac2cd47156b9768f462683a09d Mon Sep 17 00:00:00 2001 From: Juri Lelli Date: Mon, 4 Dec 2017 11:23:23 +0100 Subject: sched/cpufreq: Remove arch_scale_freq_capacity()'s 'sd' parameter The 'sd' parameter is never used in arch_scale_freq_capacity() (and it's hard to see where information coming from scheduling domains might help doing frequency invariance scaling). Remove it; also in anticipation of moving arch_scale_freq_capacity() outside CONFIG_SMP.
