[merged mm-stable] vmcoreinfo-export-section_has_mem_map.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: vmcoreinfo: export SECTION_HAS_MEM_MAP
has been removed from the -mm tree.  Its filename was
     vmcoreinfo-export-section_has_mem_map.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: vmcoreinfo: export SECTION_HAS_MEM_MAP
Date: Mon, 28 Sep 2026 10:48:21 +0200

The crash tool currently hardcodes SECTION_HAS_MEM_MAP, and makedumpfile
needs similar information (although still relying on
SECTION_MARKED_PRESENT, it should switch to SECTION_HAS_MEM_MAP).

Let's just export the value instead, so tools that work on vmcoreinfo
will not have to guess.
