Subject: [PATCH net V1 0/3] Mellanox EN driver fixes 2014-06-23


Below are some fixes to patches submitted to 3.16.

First patch is according to discussions with Ben [1] and Thomas [2] - to do not
use affinity notifier, since it breaks RFS. Instead detect changes in IRQ
affinity map, by checking if current CPU is set in affinity map on NAPI poll.
The two other patches fix some bugs introduced in commit [3].

Patches were applied and tested over commit dba6311: ('powerpc: bpf: Fix the
broken LD_VLAN_TAG_PRESENT test')


[1] -
[2] -
[3] - 554e101: ('lib/cpumask: cpumask_set_cpu_local_first to use all cores when
      numa node is not defined')

Changes from V0:
- Patch 1/3: net/mlx4_en: Don't use irq_affinity_notifier to track changes...
  - Added missing include to fix build issue on s390x arch
