From c819bfdc4a762ba8a3035815c910c2d5443b616b Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Sun, 9 Nov 2025 17:31:50 -0800 Subject: [PATCH] tool build: Remove __get_cpuid feature test This feature test is no longer used so remove. The function tested by the feature test is used in: tools/power/x86/x86_energy_perf_policy/x86_energy_perf_policy.c however, the Makefile just assumes the presence of the function and doesn't perform a build feature test for it.
