+    aarch64: use PTR_ARG and SIZE_ARG instead of DELOUSE
+    
+    DELOUSE was added to asm code to make them compatible with non-LP64
+    ABIs, but it is an unfortunate name and the code was not compatible
+    with ABIs where pointer and size_t are different. Glibc currently
+    only supports the LP64 ABI so these macros are not really needed or
+    tested, but for now the name is changed to be more meaningful instead
+    of removing them completely.
+    
+    Some DELOUSE macros were dropped: clone, strlen and strnlen used it
+    unnecessarily.
+    
+    The out of tree ILP32 patches are currently not maintained and will
+    likely need a rework to rebase them on top of the time64 changes.
+
+Keeping the DELOUSE macro avoids the need to update all string
+functions.  Lack of BTI markers and architecture variants cause many
+conflicts in a full upstream backport.
