Subject: [PATCH 0/4] IB: decrease large contigous allocation

The size of mlx4_ib_device became too large to be allocated as whole contigous 
block of memory. Currently it takes about 55K. On architecture with 4K page it 
means 3rd order.

This patch series makes an attempt to split mlx4_ib_device into several parts 
and allocate them with less expensive kvzalloc

Jan Dakinevich (4):
  IB/core: introduce ->release() callback
  IB/mlx4: move iboe field aside from mlx4_ib_dev
  IB/mlx4: move pkeys field aside from mlx4_ib_dev
  IB/mlx4: move sriov field aside from mlx4_ib_dev
