Suresh Siddha 77e81365e0 sched: Clean up domain traversal in select_idle_sibling() ... Instead of going through the scheduler domain hierarchy multiple times (for giving priority to an idle core over an idle SMT sibling in a busy core), start with the highest scheduler domain with the SD_SHARE_PKG_RESOURCES flag and traverse the domain hierarchy down till we find an idle group. This cleanup also addresses an issue reported by Mike where the recent changes returned the busy thread even in the presence of an idle SMT sibling in single socket platforms.
