Changbin Du (5):
function_graph
When function_graph is used for latency tracers, relative timestamp
is more straightforward than absolute timestamp as function trace
does. This change adds relative timestamp support to function_graph
and applies to latency tracers (wakeup and irqsoff).

kernel
Add these info fields to funcgraph wakeup tracers:
o Show CPU info since the waker could be on a different CPU.
o Show function duration and overhead.
o Show IRQ markers.

This align the behavior of wakeup tracers with irqsoff latency tracer
that we record stacktrace at the beginning and end of waking up. The
stacktrace shows us what is happening in the kernel.
