In commit 185be15143aa ("x86/mm: Remove set_pages_x() and set_pages_nx()"), the wrappers were removed as they did not provide a real benefit over set_memory_x() and set_memory_nx(). This change causes a problem because the wrappers were exported, but the underlying routines were not. As a result, external modules that used the wrappers would need to recreate a significant part of memory management.
