The series reuses some of the patches posted by Eric in his earlier attempt here[1]. Patch #1 is a fix to the Guest reboot issue on NVDIMM hot add case described here[2] and patch #2 is another fix to the nvdimm aml issue discussed here[3]. I have done a basic sanity testing of NVDIMM deviecs with Guest booting with both ACPI and DT. Further testing is always welcome. Please let me know your feedback.
