Subject: [for-next][PATCH 0/4] ftrace: Add dynamic trampoline support

This adds the allocation of dynamic trampolines. It still does not
allow for dynamic ftrace_ops to use them on CONFIG_PREEMPT systems.
That will come in 3.20, as I want to test out call_rcu_tasks() for
a bit first on my own boxes.
