[PATCH v3 18/26] sched/core: Annotate runqueues into meminspect

From: Eugen Hristev <[email protected]>

Annotate runqueues into meminspect. Even if these are static, they are
defined percpu, and a later init call will instantiate them for each
cpu. Hence, we cannot annotate them in the usual way, but rather have to
call meminspect API at init time.
