This series comes to allow user space applications to monitor real time
traffic activity and events of the verbs objects it manages, e.g.:
ibv_qp, ibv_wq, ibv_flow.
This API enables generic counters creation and define mapping
to association with a verbs object, current mlx5 driver using
this API for flow counters.
With this API, an application can monitor the entire life cycle of
object activity, defined here as a static counters attachment.
This API also allows dynamic counters monitoring of measurement points
for a partial period in the verbs object life cycle.
In addition it presents the implementation of the generic counters interface.
This will be achieved by extending flow creation by adding a new flow count
specification type which allows the user to associate a previously created
flow counters using the generic verbs counters interface to the created flow,
once associated the user could read statistics by using the read function of
the generic counters interface.
The API includes:
1. create and destroyed API of a new counters objects
2. read the counters values from HW
Note:
Attaching API to allow application to define the measurement points per objects
is a user space only API and this data is passed to kernel when the counted
object (e.g. flow) is created with the counters object.

Update mlx4 to support user MR creation against read-only memory, previously
it required the memory to be writable.
Based on rdma for-rc due to dependencies.
* mr_fix: (2 commits)
IB/mlx4: Mark user MR as writable if actual virtual memory is writable
IB/core: Make testing MR flags for writability a static inline function
To allow rereg_user_mr to modify the MR from read-only to writable without
using get_user_pages again, we needed to define the initial MR as writable.
However, this was originally done unconditionally, without taking into
account the writability of the underlying virtual memory.
As a result, any attempt to register a read-only MR over read-only
virtual memory failed.
To fix this, do not add the writable flag bit when the user virtual memory
is not writable (e.g. const memory).
However, when the underlying memory is NOT writable (and we therefore
do not define the initial MR as writable), the IB core adds a
"force writable" flag to its user-pages request. If this succeeds,
the reg_user_mr caller gets a writable copy of the original pages.
If the user-space caller then does a rereg_user_mr operation to enable
writability, this will succeed. This should not be allowed, since
the original virtual memory was not writable.

On fatal error the driver simulates CQE's for ULPs that rely on
completion of all their posted work-request.
For the GSI traffic, the mlx5 has its own mechanism that sends the
completions via software CQE's directly to the relevant CQ.
This should be kept in fatal error too, so the driver should simulate
such CQE's with the specified error state in order to complete GSI QP
work requests.

These management packets have an opcode of IB_OPCODE_UD_SEND_ONLY,
a fixed 3Byte pad, and a header length of 24Bytes.

The current implementation always checked against dpi=0 doorbell range
leading to a wrong mapping for doorbell bar. (It entered an else case
that mapped the address differently). qedr_mmap should only be used
for doorbells, so the else was actually wrong in the first place.
This only has an affect on arm architecture and not an issue on a
x86 based architecture.
This lead to doorbells not occurring on arm based systems and left
applications that use more than one dpi (or several applications
run simultaneously ) to hang.
