6.6-stable review patch. If anyone has any objections, please let me know.

commit 06eaa824fd239edd1eab2754f29b2d03da313003 upstream.
The second parameter of memblock_set_node() is size instead of end.
Since it iterates from lower address to higher address, finally the node id is correct. But during the process, some of them are wrong.
Pass size instead of end.
