As suggested by Herbert, this is another approach to using the blkcipher walk API from a context where no [a]blkcipher transform instance exists.
I have copied some data that is retrieved from the transform into the blkcipher_walk struct, and added alternative blkcipher init and walk functions that allow these data member (iv size, alignmask, etc) to be supplied directly. Suggestions for better names than blkcipher_walk_init_raw and blkcipher_walk_virt_raw are highly appreciated.
