Hi FelixCuioc,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on iommu/next]
[also build test ERROR on linux/master linus/master v5.8-rc7 next-20200730]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use

region.BIOS report the specified reserved memory region through
RMRR structures.Add analysis of ACPI device in RMRR and establish
identity mapping for ACPI device.
