+Subject: smp: Provide 'setup_max_cpus' definition on UP too
+
+From: Ingo Molnar <mingo@kernel.org>
+
+commit 3c2f8859ae1ce53f2a89c8e4ca4092101afbff67 upstream.
+
+This was already defined locally by init/main.c, but let's make
+it generic, as arch/x86/kernel/cpu/topology.c is going to make
+use of it to have more uniform code.
