SVN rev 197226 on 2009-09-15 19:14:25Z by attilio
MFC r197223:
Fix sched_switch_migrate() by assuming locks cannot be shared and a
deadlock between 3 different threads by acquiring both runqueue locks
when doing the migration.
Please note that this is a special condition as we want this fix in
before RC1 as we assume it is critical and so it has been handled
as an instant-merge. For the STABLE_7 branch, 1 week before the MFC
is assumed.
