[PATCH 04/19] context_tracking: Rename context_tracking_cpu_set() to context_tracking_cpu_track_user()

[Frederic Weisbecker]

context_tracking_cpu_set() is called in order to tell a CPU to track
user/kernel transitions. Since context tracking is going to expand in
to also track transitions from/to idle/IRQ/NMIs, the scope
of this function name becomes too broad and needs to be made more
specific.
