> arch_timer.h includes linux/smp.h since the commit:
>
>   6acc71ccac7187fc ("arm64: arch_timer: Allows a CPU-specific erratum to only affect a subset of CPUs")
>
> It was included to use DEFINE_PER_CPU(), etc. But It should have
> included <linux/percpu.h> rather than <linux/smp.h>. It worked because
> smp.h includes percpu.h.
>
> The next commit will remove percpu.h from smp.h and it will break this
> usage.
>
> Explicitly include percpu.h and remove smp.h
