69e68b4f03 mm: cleanup follow_page_mask() 
Cleanups:
 - move pte-related code to separate function. It's about half of the
   function;
 - get rid of some goto-logic;
 - use 'return NULL' instead of 'return page' where page can only be
   NULL;

pretty much self-contained let's move it to separate file.
