On allocation we use the array size and on destruction num_ports, use the
array size of destruction as well, in this context the array corresponds
to the native/actual ports on the NIC so no need to adjust this logic for
representors.

In downstream patches we will need access to the ports before doing any
stages, in order to set net device per representor.

Simplify drivers by ensuring lifetime of ib_ah object. The changes
in .create_ah() go hand in hand with relevant update in .destroy_ah().
We will use this opportunity and convert .destroy_ah() to don't fail, as
it was suggested a long time ago, because there is nothing to do in case
of failure during destroy.

The mlx5 Sub-Function (SF) sub device will be introduced in
subsequent patches. It will be created as mediated device and
belong to mdev bus. It is necessary to treat dma operations on
PF, VF and SF in uniform way, hence reduce the dependency on
pdev pci dev struct and work directly out of newly introduced
'struct device' from previous patch.
This patch does not change any functionality.

When scatter to CQE is enabled on a DCT QP it corrupts the mailbox command
since it tried to treat it as as QP create mailbox command instead of a
DCT create command.
The corrupted mailbox command causes userspace to malfunction as the
device doesn't create the QP as expected.
A new mlx5 capability is exposed to user-space which ensures that it will
not enable the feature on DCT without this fix in the kernel.

This merge commit includes some misc shared code updates from mlx5-next branch needed

1) From Maxim, Remove un-used macros and spinlock from mlx5 code.
2) From Aya, Expose Management PCIE info register layout and add rate limit

3) From Tariq, Compilation warning fix in fs_core.c
4) From Vu, Huy and Saeed, Improve mlx5 initialization flow:
The goal is to provide a better logical separation of mlx5 core
device initialization flow and will help to seamlessly support
creating different mlx5 device types such as PF, VF and SF
mlx5 sub-function virtual devices.
Mlx5_core driver needs to separate HCA resources from pci resources.
Its initialize/load/unload will be broken into stages:
1. Initialize common data structures
2. Setup function which initializes pci resources (for PF/VF)
or some other specific resources for virtual device
3. Initialize software objects according to hardware capabilities
4. Load all mlx5_core components
It is also necessary to detach mlx5_core mdev name/message from pci
device mdev->pdev name/message for a clearer report/debug of
different mlx5 device types.

When deferring a prefetch request we need to protect against MR or PD
being destroyed while the request is still enqueued.
The first step is to validate that PD owns the lkey that describes the MR
and that the MR that the lkey refers to is owned by that PD.
The second step is to dequeue all requests when MR is destroyed.
Since PD can't be destroyed while it owns MRs it is guaranteed that when a
worker wakes up the request it refers to is still valid.
Now, it is possible to refrain from taking a reference on the device since
it is assured to be present as pd.
While that, replace the dedicated ordered workqueue with the system
unbound workqueue to reuse an existing resource and improve
performance. This will also fix a bug of queueing to the wrong workqueue.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

Two flow specifications can set the ip protocol field in
the flow table entry:
1) IB_FLOW_SPEC_TCP/UDP/GRE - set the ip protocol accordingly.
2) IB_FLOW_SPEC_IPV4/6 - has ip_protocol field for users
who want to receive specific L4 packets.
We need to avoid overriding of the ip_protocol with zeros,
in case that the user first put the L4 specification and
only then the L3.

Manage indirection mkey upon DEVX flow to support ODP.
To support a page fault event on the indirection mkey it needs to be part
of the device mkey radix tree.
Both the creation and the deletion flows for a DEVX object which is
indirection mkey were adapted to handle that.

In subsequent patch, device->provider_ibdev one-to-one mapping is no

Therefore, introduce an API rdma_device_to_ibdev() that provides such

Most provider routines are callback routines which ib core invokes.
_callback suffix doesn't convey information about when such callback is
invoked. Therefore, rename port_callback to init_port.
Additionally, store the init_port function pointer in ib_device_ops, so
that it can be accessed in subsequent patches when binding rdma device to
net namespace.

Device capability bits are exposing what specific device supports from HW
perspective. Those bits are not dependent on kernel configurations and
RDMA/core should ensure that proper interfaces to users will be disabled
if CONFIG_INFINIBAND_ON_DEMAND_PAGING is not set.

Pull rdma updates from Jason Gunthorpe:
"This has been a fairly typical cycle, with the usual sorts of driver
updates. Several series continue to come through which improve and
modernize various parts of the core code, and we finally are starting
to get the uAPI command interface cleaned up.
- Various driver fixes for bnxt_re, cxgb3/4, hfi1, hns, i40iw, mlx4,
mlx5, qib, rxe, usnic
- Rework the entire syscall flow for uverbs to be able to run over
ioctl(). Finally getting past the historic bad choice to use
write() for command execution
- More functional coverage with the mlx5 'devx' user API
- Start of the HFI1 series for 'TID RDMA'
- SRQ support in the hns driver
- Support for new IBTA defined 2x lane widths
- A big series to consolidate all the driver function pointers into a
big struct and have drivers provide a 'static const' version of the
struct instead of open coding initialization
- New 'advise_mr' uAPI to control device caching/loading of page
tables
- Support for inline data in SRPT
- Modernize how umad uses the driver core and creates cdev's and
sysfs files
- First steps toward removing 'uobject' from the view of the drivers"

The per-port Q counter is some kernel resource and as such may be used by
few UID(s) upon DEVX usage.
To enable using it for QP/RQ when DEVX context is used need to allocate it
with a sharing mode indication to let firmware allows its usage.
The UID = 0xffff was chosen to mark it.
