But the semantic of early_memreamp should be that it will just return a normal memory pointer instead of iomem so the fix to convert the internal implementation to return a __force __kernel make sense to me.
For iounmap I think since we have early_memremap, we have reason to add early_memunmap() so sparse will be happy.
Thanks Dave
