Hmm.... this breaks s390:
CC block/ll_rw_blk.o
block/ll_rw_blk.c: In function 'blk_rq_map_sg':
block/ll_rw_blk.c:1357: error: implicit declaration of function 'sg_dma_len'
block/ll_rw_blk.c:1357: error: lvalue required as left operand of assignment
block/ll_rw_blk.c:1358: error: implicit declaration of function 'sg_dma_address'
block/ll_rw_blk.c:1358: error: lvalue required as left operand of assignment
make[1]: *** [block/ll_rw_blk.o] Error 1
