Leon Romanovsky c546b2a3b6 IB/nes: Move user vendor structures
This patch moves nes vendor's specific structures to
common UAPI folder which will be visible to all consumers.

These structures are used by user-space library driver
(libmlx4) and currently manually copied to that library.

This move will allow cross-compile against these files and
simplify introduction of vendor specific data.

Bhaktipriya Shridhar 9e5df3125c IB/nes: Remove deprecated create_singlethread_workqueue
alloc_ordered_workqueue() replaces deprecated
create_singlethread_workqueue().

The workqueue "event_wq" queues work item &event->event_work and the
workqueue "disconn_wq" queues work item work (maps to
g_cm_core->disconn_wq).

WQ_MEM_RECLAIM has not been set since the workqueues are not being used
on a memory reclaim path.

There is no need to duplicate a lot of code that is in the kernel library for ages.
Replace duplicating code by calling to print_hex_dump() directly.

Note that output is slightly changed:
- hex and ascii parts have just two spaces delimeter
- there is no delimeter for ascii portions
- file and line removed from prefix (they were redundant anyway since previous
  output shows same closer enough)

Bart Van Assche 9aa8b3217e IB/core: Enhance ib_map_mr_sg()
The SRP initiator allows to set max_sectors to a value that exceeds
the largest amount of data that can be mapped at once with an mlx4
HCA using fast registration and a page size of 4 KB. Hence modify
ib_map_mr_sg() such that it can map partial sg-elements. If an
sg-element has been mapped partially, let the caller know
which fraction has been mapped by adjusting *sg_offset.

Christoph Hellwig e622f2f4ad IB: split struct ib_send_wr
This patch split up struct ib_send_wr so that all non-trivial verbs
use their own structure which embedds struct ib_send_wr.  This dramaticly
shrinks the size of a WR for most common operations:

sizeof(struct ib_send_wr) (old):	96

sizeof(struct ib_send_wr):		48
sizeof(struct ib_rdma_wr):		64
sizeof(struct ib_atomic_wr):		96
sizeof(struct ib_ud_wr):		88
sizeof(struct ib_fast_reg_wr):		88
sizeof(struct ib_bind_mw_wr):		96
sizeof(struct ib_sig_handover_wr):	80

And with Sagi's pending MR rework the fast registration WR will also be
down to a reasonable size:

sizeof(struct ib_fastreg_wr):		64

Ira Weiny 4cd7c9479a IB/mad: Add support for additional MAD info to/from drivers
In order to support alternate sized MADs (and variable sized MADs on OPA
devices) add in/out MAD size parameters to the process_mad core call.

In addition, add an out_mad_pkey_index to communicate the pkey index the driver
wishes the MAD stack to use when sending OPA MAD responses.

The out MAD size and the out MAD PKey index are required by the MAD
stack to generate responses on OPA devices.

Furthermore, the in and out MAD parameters are made generic by specifying them
as ib_mad_hdr rather than ib_mad.

Drivers are modified as needed and are protected by BUG_ON flags if the MAD
sizes passed to them is incorrect.

Matan Barak bcf4c1ea58 IB/core: Change provider's API of create_cq to be extendible
Add a new ib_cq_init_attr structure which contains the
previous cqe (minimum number of CQ entries) and comp_vector
(completion vector) in addition to a new flags field.
All vendors' create_cq callbacks are changed in order
to work with the new API.

This commit does not change any functionality.

Ira Weiny 7738613e7c IB/core: Add per port immutable struct to ib_device
As of commit 5eb620c81c "IB/core: Add helpers for uncached GID and P_Key
searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in
the ib_device.

The per port core capability flags to be added later are also immutable data to
be stored in the ib_device object.

In preparation for this create a structure for per port immutable data and
place the pkey and gid table lengths within this structure.

"get_port_immutable" is added as a mandatory device function to allow the
drivers to fill in this data.
