Hi Christoph,

For the changes in arch/arm64, Will gave his ack here:
https://lore.kernel.org/linux-iommu/20200821090116.GB20255@willie-the-truck/

and the patchset has been refined to v8
https://lore.kernel.org/linux-iommu/20200823230309.28980-1-song.bao.hua@hisilicon.com/
with one additional patch to remove magic number:
[PATCH v8 3/3] mm: cma: use CMA_MAX_NAME to define the length of cma name array
https://lore.kernel.org/linux-iommu/20200823230309.28980-4-song.bao.hua@hisilicon.com/

Hopefully, you didn't miss it:-)
Does the new one need an Ack from Linux-mm maintainer?

Thanks
Barry
