Just to confirm, is this going as a fix ? We want to drop exporting
cpu_logical_map in v5.9 so this needs to go as fix. I missed it earlier,
actually,
Fixes: df320f89359c ("cpufreq: Add Tegra194 cpufreq driver")
is appropriate here so that we can drop export symbol which was part of
Commit eaecca9e7710 ("arm64: Fix __cpu_logical_map undefined issue")
as a workaround to fix the build.
