[Andrew Morton]

The quilt patch titled
     Subject: math.h: amend abs() kernel-doc and add a note about signed type limits
has been removed from the -mm tree.  Its filename was
     mathh-amend-kernel-doc-and-add-a-note-about-signed-type-limits.patch

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

Subject: math.h: amend abs() kernel-doc and add a note about signed type limits
Date: Thu, 6 Nov 2025 16:20:51 +0100

- amend the kernel-doc so the description is decoupled from the
  parameter descriptions.

- add a note to explain behaviour for the signed types when supplied
  value is the minimum (e.g., INT_MIN for int type).
