I suspect the whole series could use some reordering.

patch 1:

add ->bio_split and blk_queue_split

patch 2..n:

one for each non-trivial driver that implements ->merge_bvec_fn to
remove it and instead split bios in ->make_request. The md patch
to do the right thing in chunk_aligned_read goes into the general
md patch here. The bcache patch also goes into this series.

patch n+1:

- add blk_queue_split calls for remaining trivial drivers

patch n+2:

- remove ->merge_bvec_fn and checking of max_sectors a for all
drivers, simplify bio_add_page

patch n+2:

- remove splitting in blkdev_issue_discard

patch n+3

- remove bio_fits_rdev

patch n+4

- remove bio_get_nr_vecs

patch n+4

- use bio_add_page

patch n+5

- update documentation
