As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. As I'm interested in the relative comparison I can just compare the total runtimes (the "real" time) for the same result. Theory (A) is most likely based on the frame widths in the flame graph.
