Current behaviour assumes that memory in RAM is contiguous and

In dis contiguous platform, we just finish up walking linear

Yes, that is what the following example explains.
If memory exists at 0-5 GB and 6-10 GB then the current approach will
check if entries exist in the hash table from 0GB to 9GB. This patch
changes the behaviour to iterate up to the end of RAM.
So it fixes the commit which added memblock_phys_mem_size().
Hence needs "Fixes: " tag as well.
Woops, will add that!
