David,

I pulled down the net-next tree and the issue is with the first patch:
0001-Drivers-hv-vmbus-Export-the-vmbus_sendpacket_pagebuf.patch

The net-next tree is not current with Greg's tree and this patch is on code that
is in Greg's tree. This patch merely exports an API that is already in Greg's tree.
Greg wanted me to take this patch through your tree since the only user
of this functionality is the network driver. Any suggestions on how I should 
proceed here.

The second patch:
0002-hyperv-Support-batched-notification.patch

applies cleanly to your tree.

Regards,

K. Y
