# HG changeset patch # User Kevin Tian <kevin.tian@intel.com> # Date 1314800303 -3600 # Node ID 42d76c68b2bfbedee3e5f79d32344e14bce48b0f # Parent 51983821efa4db4040ae1c5063a4404791597699 x86: add irq count for IPIs such count is useful to assist decision make in cpuidle governor, while w/o this patch only device interrupts through do_IRQ is currently counted.
