The quilt patch titled
     Subject: dma-remap: drop nth_page() in dma_common_contiguous_remap()

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: dma-remap: drop nth_page() in dma_common_contiguous_remap()
Date: Mon, 1 Sep 2025 17:03:44 +0200

dma_common_contiguous_remap() is used to remap an "allocated contiguous
region".  Within a single allocation, there is no need to use nth_page()
anymore.

Neither the buddy, nor hugetlb, nor CMA will hand out problematic page
ranges.
