+
+    Don't write beyond destination in __mempcpy_avx512_no_vzeroupper (bug 23196)
+    
+    When compiled as mempcpy, the return value is the end of the destination
+    buffer, thus it cannot be used to refer to the start of it.
+
+Conflicts:
+	sysdeps/x86_64/multiarch/memmove-avx512-no-vzeroupper.S
+
+Change applied to sysdeps/x86_64/multiarch/memcpy-avx512-no-vzeroupper.S
+instead.
