Subject: [PATCH 05/19] perf stat: Add cpu aggr id for no aggregation mode
Date:   Thu, 13 Oct 2022 23:15:36 -0700
Message-Id: <20221014061550.463644-6-namhyung@kernel.org>
In-Reply-To: <20221014061550.463644-1-namhyung@kernel.org>

Likewise, add an aggr_id for cpu for none aggregation mode.  This is not
used actually yet but later code will use to unify the aggregation code.

No functional change intended.
