FROMLIST: fix arm64 build with lack of __cpu_logical_map exported

Browse Source 
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.
