Sasha,

This patch and the upstream commit 26e495f34107 ("iommu/amd: Restore IRTE.RemapEn bit after programming IRTE") are related. Since the commit 26e495f34107 has been back-ported to linux-5.4.y branch of the stable tree, this patch should also be add to linux-5.4.y as well.

It doesn't apply to 5.4.y at all, can someone please provide a working backport?

thanks,

greg k-h

Let me work on this and send upstream.

Thank you, Suravee
