This patch series adds support for
- allocating rx pages local to the interrupt
- setting affinity hint to influence IRQs to be allocated on the
same NUMA node as the one where the card resides.

sfc: use __GFP_NOWARN when allocating RX pages from atomic context.

From: Bert Kenward
With CONFIG_HAVE_MEMORYLESS_NODES cpu_to_node() may return
nodes without memory, which is not a good choice when later
using that to allocate memory. cpu_to_mem() instead provides
the most appropriate NUMA node to allocate from.

When the interrupt servicing a channel is on a NUMA node that is

rx pages on the node local to the interrupt (remote to the device)

From: Bert Kenward
Use cpumask_local_spread to provide interrupt affinity hints
for each queue. This will spread interrupts across NUMA local
CPUs first, extending to remote nodes if needed.

If we fail to allocate a page when in atomic context this is
handled by scheduling a fill in non-atomic context.
As such, a warning is not needed.

No big issue. Maybe Stephen can clarifiy things. I mean acknowledge no

Testing of the new UDP bearer has revealed that reception of
NAME_DISTRIBUTOR, LINK_PROTOCOL/RESET and LINK_PROTOCOL/ACTIVATE
message buffers is not prepared for the case that those may be
non-linear.
We now linearize all such buffers before they are delivered up to the
generic reception layer.

This patch changes how the multipath hash is computed for locally
generated UDP or TCP flows: now the hash comprises also l4 information
(source and destination port).
This allows better utilization of the available paths when the existing
flows have the same source IP and the same destination IP:
