Cover letter [PATCH v2 0/7] arm64: numa/topology/smp: update the cpumasks for CPU hotplug
Hi Sudeep,
Quoted 5 lines · Sudeep Holla
was reported to cause some hotplug and system suspend regressions when it was merged. On investigation, it was found that unlike x86/PPC, arm64 doesn't update the cpu and numa masks on CPU hotplug. That's somewhat expected from the scheduler.

Since these changes were bit invasive as a solution to the above mentioned regression, as small change was temporarily applied as a fix. This series updates the cpu and numa masks on CPU hotplug and reverts that temporary fix.
It would be good to get this tested(CPU hotplug - few and all CPUs in a socket) on multi-socket/NUMA systems from Cavium and Huawei/Hisilicon.
This is looking pretty good to me. I've made some minor comments on a couple of the patches, so please address those and repost with the Tested-bys that you received, then I can queue this for 4.19.
Thanks,
Will
