From: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
PEM: o Would it be possible to make this bisectable as follows?
a. Insert a new patch after current patch 4/6 that defines destroy_rcu_head_on_stack(), init_rcu_head_on_stack(), and init_rcu_head() with their !CONFIG_DEBUG_OBJECTS_RCU_HEAD definitions.
This patch performs this transition.
