[PULL][lunar] sched: cpumask: improve on cpumask_local_spread() locality

[dann frazier]

BugLink: https://bugs.launchpad.net/bugs/2008824

A patch series landed upstream during the v6.3 merge window that shows
impressive performance improvements in iperf3 multi-stream performance
on NUMA based systems w/ Mellanox network controllers:
  https://www.spinics.net/lists/linux-rdma/msg115357.html

It cherry-picks cleanly back to lunar's 6.2. I looked for any
following commits with Fixes: references to these commits, and found
one which I've also included here.

Running our 8 client ubuntu_performance_iperf3 test from autotest
shows a 7% improvement with a test kernel I built in ppa:dannf/mlnxaffinity.
(I measured w/o "set_irq_affinity.sh" tuning, so I could see the
impact on default behavior).

The following changes since commit a89b4899c906ed38ab38a41f4d2448d834e42b8e:
