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

[Suren Baghdasaryan <surenb@google.com>]

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()).
