df5fc62c69 ("sched/fair: Fix wake_affine() for !NUMA_BALANCING"): general protection fault: 0000 [#1] PREEMPT SMP KASAN

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git sched/wip commit df5fc62c696165c15520e2af5eb077fe20bcfcfd Author: Peter Zijlstra <peterz(a)infradead.org> AuthorDate: Mon Jul 31 17:50:05 2017 +0200 Commit: Peter Zijlstra <peterz(a)infradead.org> CommitDate: Mon Jul 31 17:50:48 2017 +0200 sched/fair: Fix wake_affine() for !NUMA_BALANCING In commit: 3fed382b46ba ("sched/numa: Implement NUMA node level wake_affine()") Rik changed wake_affine to consider NUMA information when balancing between LLC domains. There are a number of problems here which this patch tries to address: - LLC < NODE; in this case we'd use the wrong information to balance - !NUMA_BALANCING: in this case, the new code doesn't do any balancing at all - re-computes the NUMA data for every wakeup, this can mean iterating up to 64 CPUs for every wakeup. - default affine wakeups inside a cache We address these by saving the load/capacity values for each sched_domain during regular load-balance and using these values in wake_affine_llc(). The obvious down-side to using cached values is that they can be too old and poorly reflect reality. But this way we can use LLC wide information and thus not rely on assuming LLC matches NODE. We also don't rely on NUMA_BALANCING nor do we have to aggegate two nodes (or even cache domains) worth of CPUs for each wakeup.
