Kefeng Wang cf6a1d16c6 mm: use memalloc_nofs_save() in page_cache_ra_order() 
commit 30153e4466 upstream.

See commit f2c817bed5 ("mm: use memalloc_nofs_save in readahead path"),
ensure that page_cache_ra_order() do not attempt to reclaim file-backed
pages too, or it leads to a deadlock, found issue when test ext4 large
folio.
