Now as all commands use mlx5 ifc interface, instead of doing two calls
for executing a command we embed command status checking into
mlx5_cmd_exec to simplify the interface.
Also we do here some cleanup for redundant software structures
(inbox/outbox) and functions and improved command failure output.

Prior to this patch we assumed that modify QP commands have the
same layout.
In ConnectX-4 for each QP transition there is a specific command
and their layout can vary.
e.g: 2err/2rst commands don't have QP context in their layout and before
this patch we posted the QP context in those commands.
Fortunately the FW only checks the suffix of the commands and executes
them, while ignoring all invalid data sent after the valid command
layout.
This patch removes mlx5_modify_qp_mbox_in and changes
mlx5_core_qp_modify to receive the required transition and QP context
with opt_param_mask if needed. This way the caller is not required to
provide the command inbox layout and it will be generated automatically.
mlx5_core_qp_modify will generate the command inbox/outbox layouts
according to the requested transition and will fill the requested
parameters.

It is useful to know the reason why cpufreq_update_util() has just
been called and that can be passed as flags to cpufreq_update_util()
and to the ->func() callback in struct update_util_data. However,
doing that in addition to passing the util and max arguments they
already take would be clumsy, so avoid it.
Instead, use the observation that the schedutil governor is part
of the scheduler proper, so it can access scheduler data directly.
This allows the util and max arguments of cpufreq_update_util()
and the ->func() callback in struct update_util_data to be replaced
with a flags one, but schedutil has to be modified to follow.
Thus make the schedutil governor obtain the CFS utilization
information from the scheduler and use the "RT" and "DL" flags
instead of the special utilization value of ULONG_MAX to track
updates from the RT and DL sched classes. Make it non-modular
too to avoid having to export scheduler variables to modules at
large.
Next, update all of the other users of cpufreq_update_util()
and the ->func() callback in struct update_util_data accordingly.

Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of
certain interrupt types, pass positive flags like PCI_IRQ_LEGACY,
PCI_IRQ_MSI, etc., to specify the acceptable interrupt types.
This is based on a number of pending driver conversions that just happend
to be a whole more obvious to read this way, and given that we have no
users in the tree yet it can still easily be done.
I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting
all interrupt types very simple.

We seem to have a bit a mess in how to describe the bus formats, with

use MEDIA_BUS_FMT_ also for the hdmi color formats and high color
modes.
Also move all the display_info related functions into drm_connector.c
(there's only one) to group it all together. I did decided against
also moving the edid related display info functions, they seem to fit
better in drm_edid.c. Instead sprinkle a few cross references around.
While at that reduce the kerneldoc for static functions, there's not

Daniel Vetter proposed a new challenge to the serialisation inside the
busy-ioctl that exposed a flaw that could result in us reporting the
wrong engine as being busy. If the request is reallocated as we test
its busyness and then reassigned to this object by another thread, we
would not notice that the test itself was incorrect.
We are faced with a choice of using __i915_gem_active_get_request_rcu()
to first acquire a reference to the request preventing the race, or to
acknowledge the race and accept the limitations upon the accuracy of the
busy flags. Note that we guarantee that we never falsely report the
object as idle (providing userspace itself doesn't race), and so the
most important use of the busy-ioctl and its guarantees are fulfilled.

Ensure that the inner_protocol is set on transmit so that GSO segmentation,
which relies on that field, works correctly.
This is achieved by setting the inner_protocol in gre_build_header rather
than each caller of that function. It ensures that the inner_protocol is
set when gre_fb_xmit() is used to transmit GRE which was not previously the
case.
I have observed this is not the case when OvS transmits GRE using
lwtunnel metadata (which it always does).

Currently bcma-hcd driver handles 3 different bcma cores:

2) BCMA_CORE_NS_USB20 (0x504)
3) BCMA_CORE_NS_USB30 (0x505)
The first one was introduced years ago and so far was used on MIPS
devices only. All Northstar (ARM) devices were using other two cores
which allowed easy implementation of separated initialization paths.
It seems however Broadcom decided to reuse this old USB 2.0 controller
on some recently introduced cheaper Northstar BCM53573 SoCs. I noticed
this on Tenda AC9 (based on BCM47189B0 belonging to BCM53573 family).
There is no difference in this old controller core identification
between MIPS and ARM devices: they share the same id and revision. We
need different controller initialization procedure however.
To handle this add a check for architecture and implement required
initialization for ARM case.

The idea for type_check in dev_get_nest_level() was to count the number
of nested devices of the same type (currently, only macvlan or vlan
devices).
This prevented the false positive lockdep warning on configurations such
as:
eth0 <--- macvlan0 <--- vlan0 <--- macvlan1
However, this doesn't prevent a warning on a configuration such as:
eth0 <--- macvlan0 <--- vlan0
eth1 <--- vlan1 <--- macvlan1
In this case, all the locks end up with a nesting subclass of 1, so
lockdep thinks that there is still a deadlock:
- in the first case we have (macvlan_netdev_addr_lock_key, 1) and then
take (vlan_netdev_xmit_lock_key, 1)
- in the second case, we have (vlan_netdev_xmit_lock_key, 1) and then
take (macvlan_netdev_addr_lock_key, 1)
By removing the linktype check in dev_get_nest_level() and always
incrementing the nesting depth, lockdep considers this configuration
valid.
