Some processors use the Interrupt Response Time Limit (IRTL) MSR value to describe the maximum IRQ response time latency for deep package C-states. (Though others have the register, but do not use it) Lets print it out to give insight into the cases where it is used. IRTL begain in SNB, with PC3/PC6/PC7, and HSW added PC8/PC9/PC10.
