The quilt patch titled
     Subject: mm: memblock: fix arguments passed to memblock_set_node()
has been removed from the -mm tree.  Its filename was
     mm-memblock-fix-arguments-passed-to-memblock_set_node.patch

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: mm: memblock: fix arguments passed to memblock_set_node()
Date: Fri, 25 Apr 2025 10:20:03 +0000

memblock_set_node() receives a `base` and a `size` arguments, but we are
passing the `start` and `end` of the memory regions when iterating over
them in memmap_init_reserved_pages() to set their node ids.

This results in the function setting the node ids for the reserved memory
regions in `[base, base + base + size)` instead of `[base, base + size)`.

Pass `start` and `size`, so that we iterate over the correct range.
