Subject: [PATCH] mm/page_owner: set page_owner_* storage-class-specifier to static

smatch reports
mm/page_owner.c:739:30: warning: symbol
'page_owner_stack_operations' was not declared. Should it be static?
mm/page_owner.c:748:5: warning: symbol
'page_owner_threshold_get' was not declared. Should it be static?
mm/page_owner.c:754:5: warning: symbol
'page_owner_threshold_set' was not declared. Should it be static?

This variable and functions are only used in their defining file,
so it should be static
