2013-11-08mlx5: Support communicating arbitrary host page size to firmwareEli Cohen
Connect-IB firmware requires 4K pages to be communicated with the driver. This patch breaks larger pages to 4K units to enable support for architectures utilizing larger page size, such as PowerPC. This patch also fixes several places that referred to PAGE_SHIFT instead of explicit 12 which is the inherent page shift on Connect-IB.

2013-11-08IB/mlx5: Fix srq free in destroy qpMoshe Lazer
On destroy QP the driver walks over the relevant CQ and removes CQEs reported for the destroyed QP. It also frees the related SRQ entry without checking that this is actually an SRQ-related CQE. In case of a CQ used for both send and receive QP, we could free SRQ entries for send CQEs. This patch resolves this issue by verifying that this is a SRQ related CQE by checking the SRQ number in the CQE is not zero.

2013-07-08mlx5: Add driver for Mellanox Connect-IB adaptersEli Cohen
The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.
