mm: remove gfp_mask from add_to_swap
Remove gfp_mask argument from add_to_swap(): it's misleading because its only caller, shrink_page_list(), is not atomic at that point; and in due course (implementing discard) we'll sometimes want to allocate some memory with GFP_NOIO (as is used in swap_writepage) when allocating swap. No change to the gfp_mask passed down to add_to_swap_cache(): still use __GFP_HIGH without __GFP_WAIT (with nomemalloc and nowarn as before): though it's not obvious if that's the best combination to ask for here.
