Subject: [PATCH 0/2] Interrupt Aware Scheduler

This patch introduces Interrupt Aware Scheduler(IAS). The tests till now
show an overall improvement in cases where the workload has some
interrupt activity.

The patch avoids CPUs which might be considered interrupt-heavy when
trying to schedule threads (on the push side) in the system. Interrupt
Awareness has only been added into the fair scheduling class.
