Subject: [PATCH 1/1] alloc_tag: Export memory allocation profiling symbols
 used by modules

Export mem_alloc_profiling_key, page_ext_get() and page_ext_set() symbols
as they can be used by modules (mem_alloc_profiling_key is used indirectly
via mem_alloc_profiling_enabled()).

Closes: https://lore.kernel.org/oe-kbuild-all/202407080044.DWMC9N9I-lkp@intel.com/
