From c0f97f20e5d97a1358ade650fcf6a322c0c9bc72 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 24 Jul 2020 20:22:05 -0700 Subject: rcu: Move rcu_cpu_started per-CPU variable to rcu_data When the rcu_cpu_started per-CPU variable was added by commit f64c6013a202 ("rcu/x86: Provide early rcu_cpu_starting() callback"), there were multiple sets of per-CPU rcu_data structures. Therefore, the rcu_cpu_started flag was added as a separate per-CPU variable. But now there is only one set of per-CPU rcu_data structures, so this commit moves rcu_cpu_started to a new ->cpu_started field in that structure. Signed-off-by: Paul E.
