Hi Dave,
I spent a few cycles on transmit problems for af_iucv over regular
netdevices - please apply the following fixes to -net.

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
