The computation: end = start + (size - (start_phys_aligned - start_phys)) / incr could theoretically underflow if size < offset, leading to a massive iteration. Add VM_WARN_ON_ONCE() to detect cases where the region size is smaller than the alignment offset. While this should never happen in practice due to memblock guarantees, the warning helps catch potential bugs in early memory initialization code.
