[PATCH v2 17/25] sched/core: Annotate runqueues into meminspect

[Mukesh Ojha]

From: Eugen Hristev <eugen.hristev@xxxxxxxxxx>

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.
