Michel Lespinasse 956cb3f228 FROMLIST: mm: create new include/linux/vm_event.h header file ...

Split off the definitions necessary to update event counters from vmstat.h
into a new vm_event.h file.

The rationale is to allow header files included from mm.h to update
counter events. vmstat.h can not be included from such header files,
because it refers to page_pgdat() which is only defined later down
in mm.h, and thus results in compile errors. vm_event.h does not refer
to page_pgdat() and thus does not result in such errors.
