Subject: [PATCH net-next V1 0/2]  net: Affinity hint helper function

Hi,

This patchset will set affinity hint to influence IRQs to be allocated on the
same NUMA node as the one where the card resides. As discussed in
http://www.spinics.net/lists/netdev/msg271497.html

If number of IRQs allocated is greater than the number of local NUMA cores, all
local cores will be used first, and the rest of the IRQs will be on a remote
NUMA node.
If no NUMA support - IRQ's and cores will be mapped 1:1

The patch was tested and applied on top of commit 750f679 "Merge branch '6lowpan'"

Amir
