Michal Hocko da6bc57a8f net: use kvmalloc with __GFP_REPEAT rather than open coded variant ... fq_alloc_node, alloc_netdev_mqs and netif_alloc* open code kmalloc with vmalloc fallback. Use the kvmalloc variant instead. Keep the __GFP_REPEAT flag based on explanation from Eric: "At the time, tests on the hardware I had in my labs showed that vmalloc() could deliver pages spread all over the memory and that was a small penalty (once memory is fragmented enough, not at boot time)" The way how the code is constructed means, however, that we prefer to go and hit the OOM killer before we fall back to the vmalloc for requests <=32kB (with 4kB pages) in the current code. This is rather disruptive for something that can be achived with the fallback. On the other hand __GFP_REPEAT doesn't have any useful semantic for these requests. So the effect of this patch is that requests which fit into 32kB will fall back to vmalloc easier now.
