+Subject: [PATCH] xf86atomic: require CAS support in libatomic_ops
+
+Since AO_compare_and_swap_full() is used by libdrm, AO_REQUIRE_CAS
+must be defined before including <atomic_ops.h> so that we are sure
+that CAS support will be provided. This is necessary to make sure that
+the AO_compare_and_swap_full() function will be provided on all
+architectures, including the ones that don't have built-in CAS support
+such as SPARCv8.
