The first patch allows for skb allocations outside of GFP_DMA, while the second patch respects that drivers might use skb_cow_head() and/or want additional dev->needed_headroom. Patch 3 is for a separate issue, where we didn't setup some of the netdevice-specific infrastructure when running as a z/VM guest. Thanks, Julian Julian Wiedmann (3): net/af_iucv: remove GFP_DMA restriction for HiperTransport net/af_iucv: build proper skbs for HiperTransport net/af_iucv: always register net_device notifier net/iucv/af_iucv.c | 49 ++++++++++++++++++++++++++++++++++------------ 1 file changed, 36 insertions(+), 13 deletions(-) -- 2.17.1
