Subject: [PATCH 0/2] Add tracepoints to trace all x86 system IRQs

This is a patch series aiming to trace all the x86 system IRQs. The
tracepoints make it easier to understand IRQ interaction with other
system events and how do the IRQs affect the system behavior.

Patch#0 adds irq_handler_{entry,exit} tracepoints to x86 timer interrupt
handler.
Patch#1 creates a irq_vectors/ event sub system and
irq_vectors_{entry,exit} trace events. It adds tracepoints to all x86
IRQ vector handlers.

Currently the patch only adds tracepoints to x86. A similar approach can
be taken with other architectures to trace IRQ vectors in the system.
