Subject: [PATCH repost] sched: export sched_set/getaffinity to modules

Author: Sridhar Samudrala <sri@...ibm.com>

sched: export sched_set/getaffinity to modules

vhost-net driver wants to copy the affinity from the
owner thread to thread it creates. Export
sched_set/get affinity to modules to make this possible
when vhost is built as a module.
