The FENCE indicator in hns WQE doesn't ensure that response data from
a previous Read/Atomic operation has been written to the requester's
memory before the subsequent Send/Write operation is processed. This
may result in the subsequent Send/Write operation accessing the original
data in memory instead of the expected response data.
Unlike FENCE, the SO (Strong Order) indicator blocks the subsequent
operation until the previous response data is written to memory and a
bresp is returned. Set the SO indicator instead of FENCE to maintain
strict order.

Implement the device API for ufile_hw_cleanup operation, which
iterates over the ufile uobjects lists, and attempts to destroy
DevX QPs, by issuing up to 8 commands in parallel.
This function is responsible only for cleaning the FW resources of the
QP, and doesn't necessarily cleanup all of its resources.
Hence the normal serialized cleanup flow is still executed after it
in __uverbs_cleanup_ufile() to cleanup the remaining resources and
handle the cleanup of SW objects.
In order to avoid double cleanup for the FW resources, new DevX flag
was added DEVX_OBJ_FLAGS_HW_FREED, which marks the object's FW resources
as already freed.
Since QP destruction is the most time-consuming operation in FW,
parallelizing it reduces the cleanup time of applications that use
DevX QPs.

Fix a race condition when creating a lag bond in active backup
mode where after the bond creation the backup slave was
attached to the IB device, instead of the active slave.
This caused stale entries in the GID table, as the gid updating
mechanism relies on ib_device_get_netdev(), which would return
the backup slave.
Send an MLX5_DRIVER_EVENT_ACTIVE_BACKUP_LAG_CHANGE_LOWERSTATE
event when activating the lag, additionally to when modifying
the lag. This ensures that eventually the active netdevice is
stored in the bond IB device.
When handling this event remove the GIDs of the previously
attached netdevice in this port and rescan the GIDs of the
newly attached netdevice.
This ensures that eventually the active slave netdevice is
correctly stored in the IB device port. While there might be
a brief moment where the backup slave GIDs appear in the GID
table, it will eventually stabilize with the correct GIDs
(of the bond and the active slave).

- enable srq_used when RC QP is configured to use SRQ.
- set the type based on the QP type.

system registers as we're about to fail
* Make sure that the host's vector length is at capped by a value
common to all CPUs

The blank line causes execve() to fail:
# strace ./postinst
execve("./postinst", ...) = -1 ENOEXEC (Exec format error)
strace: exec: Exec format error
+++ exited with 1 +++
However running the scripts via shell does work (at least with bash)
because the shell attempts to execute the file as a shell script when
execve() fails.

If we follow "make help" to "make dt_binding_schema", we will see
below error:
$ make dt_binding_schema
make[1]: *** No rule to make target 'dt_binding_schema'. Stop.
make: *** [Makefile:224: __sub-make] Error 2
It should be a typo. So this will fix it.

x86_android_tablet_remove() frees the pdevs[] array, so it should not
be used after calling x86_android_tablet_remove().
When platform_device_register() fails, store the pdevs[x] PTR_ERR() value
into the local ret variable before calling x86_android_tablet_remove()
to avoid using pdevs[] after it has been freed.
