none of them. I did my personal patch:

struct mthca_icm *mthca_alloc_icm(struct mthca_dev *dev, int npages,
                                  gfp_t gfp_mask, int coherent)
{
        struct mthca_icm *icm;
        struct mthca_icm_chunk *chunk = NULL;
        int cur_order;
        int ret;

+        coherent = 1;
        /* We use sg_set_buf for coherent allocs, which assumes low memory */
+        //BUG_ON(coherent && (gfp_mask & __GFP_HIGHMEM));
