I don't think that's an issue.  The max_pfn is calculated from the first
e820 map, but it's already been truncated by command line.  So by the
time we get to setting up iomem (and the kernel code and data that Gerd
is after), the e820 map has a final E820_RAM mapping that ends at
max_pfn.  I suspect the end result in /proc/iomem would be the same.
