mm: move enum vm_event_item into a standalone header file
enums are problematic because they cannot be forward-declared: akpm2:/home/akpm> cat t.c enum foo; static inline void bar(enum foo f) { } akpm2:/home/akpm> gcc -c t.c t.c:4: error: parameter 1 ('f') has incomplete type So move the enum's definition into a standalone header file which can be used wherever its definition is needed.
