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));
