The quilt patch titled

has been removed from the -mm tree.  Its filename was
     mm-vma-add-page-table-limit-to-unmap_region.patch

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: mm/vma: add page table limit to unmap_region()
Date: Wed, 21 Jan 2026 11:49:41 -0500

The unmap_region() calls need to pass through the page table limit for a
future patch.

No functional changes intended.
