v2 had issues on -tip tree and triggered a warning. It seems to have
disappeared. Perhaps it was due to another timer issue. Anyway this
version brings more debugging informations, with a layout that is more
bisection-friendly and it also handles ticks that fire outside IRQ
context and thus carry NULL irq regs. This happen when
hrtimer_interrupt() is called on hotplug cpu down for example.

We'll see if the issue arises again.
