[PATCH] mm: put activate_page_pvecs and others pagevec together

["Ming Li" <mingli199x@qq.com>]

hi, I have been studying mm and learn agexxx, at the very beginning I felt confuse when I saw activatexxx, after I learned the whole thing I understood that it's similar with other pagevec's function. Can we put it with other pagevec together? I think it is easier for newbies to read and understand.

regards,
