    mm/gup.c: convert to use get_user_{page|pages}_fast_only() · dadbb612
    Souptick Joarder authored
    API __get_user_pages_fast() renamed to get_user_pages_fast_only() to
    align with pin_user_pages_fast_only().
    
    As part of this we will get rid of write parameter.  Instead caller will
    pass FOLL_WRITE to get_user_pages_fast_only().  This will not change any
    existing functionality of the API.
    
    All the callers are changed to pass FOLL_WRITE.
    
    Also introduce get_user_page_fast_only(), and use it in a few places
    that hard-code nr_pages to 1.
    
    Updated the documentation of the API.
