This is a combination of Christoph's work to refactor
generic_file_buffered_read() and some of my large-page support
which was disrupted by Kent's refactoring of generic_file_buffered_read.

v5:
 - Rebase on next-20210122 (new conflict due to typo fix)
 - Folded in Reviewed-bys
v4:
 - Rebase on next-20210120
 - Fix compilation error with pagevec_init & reinit
 - Simplify filemap_range_uptodate() by passing pos instead of iocb
v3:
 - Fixed missing put_page for readahead with IOCB_NOIO (hch)
 - Fixed commit message for lock_page_for_iocb (nborisov)
v2:
 - Added pagevec conversion upfront and rebased other patches on top of
   it (me)
 - Limit page search by max pgoff_t rather than by number of pages (me)
 - Renamed mapping_get_read_thps() to filemap_get_read_batch() (hch/me)
 - Added doc for filemap_get_read_batch() (hch/me)
 - Removed 'first' parameter from filemap_update_page() (me)
 - Folded "Remove parameters from filemap_update_page()" into an earlier
   patch (hch)
 - Restructured filemap_update_page() error handling flow (hch/me)
 - Pass the pagevec to filemap_create_page() (hch)
 - Renamed 'find_page' label to 'retry' (hch)
 - Explicitly check for AOP_TRUNCATED_PAGE instead of assuming err > 0
   means retry (hch)
 - Move mark_page_accessed() and handling of i_size into main copy loop (me)
