I assume this was to avoid compilation errors, when I rebased I got
conflict and I ordered them back alphabetically as before and hit the
compilation error.

The actual fix would be to include linux/arch_topology.h in linux/topology.h
as you are moving contents of asm/topology.h which it includes.

I did the change and get it tested by kbuild. See [1]
