A few changes after going over all the memory allocations, but mostly just
keeping the patches up to date.
This patch series is the a full release of the Intel(R) I/O
Acceleration Technology (I/OAT) for Linux. It includes an in kernel API
for offloading memory copies to hardware, a driver for the I/OAT DMA memcpy
engine, and changes to the TCP stack to offload copies of received
networking data to application space.
Changes from last posting:
Fixed a struct ioat_dma_chan memory leak on driver unload.
Changed a lock that was never held in atomic contexts to a mutex
as part of avoiding unneeded GFP_ATOMIC allocations.
These changes apply to Linus' tree as of commit
6810b548b25114607e0814612d84125abccc0a4f

2) The Intel I/OAT DMA driver (ioatdma)
3) Core networking code to setup networking as a DMA memcpy client
4) Utility functions for sk_buff to iovec offloaded copy
5) Structure changes needed for TCP receive offload
6) Rename cleanup_rbuf to tcp_cleanup_rbuf
7) Make sk_eat_skb aware of early copied packets
