Change from v8 -. add suggested-by Peterz -. add several comments
Change from v7 -. fix a trivial typo -. modify commit messages to explain what it does more clearly -. simplify code with an existing macro
Change from v6 -. add a comment about selection of fallback_cpu incase more than one exist -. modify a comment explaining what we do wrt PREFER_SIBLING
Change from v5 -. exclude two patches already picked up by peterz (sched/deadline: Make find_later_rq() choose a closer cpu in topology) (sched/deadline: Change return value of cpudl_find()) -. apply what peterz fixed for 'prefer sibling', into deadline and rt
Change from v4 -. remove a patch that might cause huge lock contention (by spin lock(&cpudl.lock) in a hot path of scheduler)
Change from v3 -. rename closest_cpu to best_cpu so that it align with rt -. protect referring cpudl.elements with cpudl.lock -. change return value of cpudl_find() to bool
Change from v2 -. add support for SD_PREFER_SIBLING
Change from v1 -. clean up the patch
Byungchul Park (2): sched/deadline: Add support for SD_PREFER_SIBLING on find_later_rq() sched/rt: Add support for SD_PREFER_SIBLING on find_lowest_rq()
