Hi, Breno,
Thanks for the review. I agree with splitting the series. I will
separate the bug fixes into an independent patchset so you can pick them
up more easily. Please note that the arm64 crash hotplug feature depends
on these fixes, so they need to land first. I will send out the split
patches soon.

Only the last three patches are related to the feature, and all the
preceding patches are bug fixes. I will separate them out.
