From 2c2320041c46f82c4a3001fff995e723f7950b9a Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Sat, 8 Aug 2020 14:42:42 +0200 Subject: [PATCH] FROMLIST: fix arm64 build with lack of __cpu_logical_map exported Currently Linus's tree fails with the following build error on arm64 makeallmodconfig: ERROR: modpost: "__cpu_logical_map" [drivers/cpufreq/tegra194-cpufreq.ko] undefined! Seems that kernel.ci also notices this for the past 2 days: https://lore.kernel.org/r/5f2c97ab.1c69fb81.160f4.0196@mx.google.com https://lore.kernel.org/r/5f2ab734.1c69fb81.24b16.8537@mx.google.com Fix this up by just exporting the symbol. Don't know if it's the "right" fix, but it solves the build error for my machines.
