rcu: Remove full memory barrier on boot time eqs sanity check
When the boot CPU initializes the per-CPU data on behalf of all possible CPUs, a sanity check is performed on each of them to make sure none is initialized in an extended quiescent state. This check involves a full memory barrier which is useless at this early boot stage. Do a plain access instead. Signed-off-by: Frederic Weisbecker <frederic@kernel.org> Signed-off-by: Paul E.
