+From d5c84ea4595ea1fbb5b213621e0966ebe0fd3cc9 Mon Sep 17 00:00:00 2001
+From: Joseph Schuchart <joseph.schuchart@stonybrook.edu>
+Date: Wed, 28 May 2025 10:11:58 -0400
+Subject: [PATCH] Force alignment of opal_atomic_int128_t to be 16B
+
+Some architectures will align 128bit integer on 8B but require 16B alignment
+for 128bit CAS instructions and otherwise fall back to a lock-based
+atomicity model. By forcing 16bit alignment we can ensure that the variables
+are properly aligned and the fall-back is not triggered.
+
+Thanks to Ulrich Weigand for the analysis and proposed fix in https://github.com/open-mpi/ompi/issues/10988#issuecomment-2913388506.
