key_serial_t fields are signed integers. Use nla_get/put_s32 for
those to avoid implicit signed conversion in the netlink protocol.

====================
mlxsw: Annotate structs with __counted_by
This annotates several mlxsw structures with the coming __counted_by attribute
for bounds checking of flexible arrays at run-time. For more details, see
commit dd06e72e68bc ("Compiler Attributes: Add __counted_by macro").

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct mlxsw_sp_span.

Kees Cook says:
====================
Batch 1: Annotate structs with __counted_by
This is the batch 1 of patches touching netdev for preparing for
the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by to structs that would
benefit from the annotation.
Since the element count member must be set before accessing the annotated
flexible array member, some patches also move the member's initialization
earlier. (These are noted in the individual patches.)

The 'interrupts' and 'reg' properties are described in synopsys,dw-hdmi.yaml,
so use 'unevaluatedProperties: false' so that these two properties can
be accepted.

ovl_permission() accesses ->layers[...].mnt; we can't have ->layers
freed without an RCU delay on fs shutdown.
Fortunately, kern_unmount_array() that is used to drop those mounts
does include an RCU delay, so freeing is delayed; unfortunately, the
array passed to kern_unmount_array() is formed by mangling ->layers
contents and that happens without any delays.
The ->layers[...].name string entries are used to store the strings to
display in "lowerdir=..." by ovl_show_options(). Those entries are not
accessed in RCU walk.
Move the name strings into a separate array ofs->config.lowerdirs and
reuse the ofs->config.lowerdirs array as the temporary mount array to
pass to kern_unmount_array().

Commit 4e0871333661 ("ASoC: hdmi-codec: fix channel info for
compressed formats") accidentally changed hcp->chmap_idx from
ca_id, the CEA channel allocation ID, to idx, the index to
the table of channel mappings ordered by preference.
This resulted in wrong channel maps being reported to userspace,
eg for 5.1 "FL,FR,LFE,FC" was reported instead of the expected
"FL,FR,LFE,FC,RL,RR":
~ # speaker-test -c 6 -t sine
...
0 - Front Left
3 - Front Center
1 - Front Right
2 - LFE
4 - Unknown
5 - Unknown
~ # amixer cget iface=PCM,name='Playback Channel Map' | grep ': values'
: values=3,4,8,7,0,0,0,0
Switch this back to ca_id in case of PCM audio so the correct channel
map is reported again and set it to HDMI_CODEC_CHMAP_IDX_UNKNOWN in
case of non-PCM audio so the PCM channel map control returns "Unknown"
channels (value 0).

SNP retrieves the majority of CPUID information from the SNP CPUID page.
But there are times when that information needs to be supplemented by the
hypervisor, for example, obtaining the initial APIC ID of the vCPU from
leaf 1.
The current implementation uses the MSR protocol to retrieve the data from
the hypervisor, even when a GHCB exists. The problem arises when an NMI
arrives on return from the VMGEXIT. The NMI will be immediately serviced
and may generate a #VC requiring communication with the hypervisor.
Since a GHCB exists in this case, it will be used. As part of using the
GHCB, the #VC handler will write the GHCB physical address into the GHCB
MSR and the #VC will be handled.
When the NMI completes, processing resumes at the site of the VMGEXIT
which is expecting to read the GHCB MSR and find a CPUID MSR protocol
response. Since the NMI handling overwrote the GHCB MSR response, the
guest will see an invalid reply from the hypervisor and self-terminate.
Fix this problem by using the GHCB when it is available. Any NMI
received is properly handled because the GHCB contents are copied into
a backup page and restored on NMI exit, thus preserving the active GHCB
request or result.

Initialize the structure to 0 so that it's fields won't have random
values. For example fields like rec.traffic_class (as well as
rec.flow_label and rec.sl) is used to generate the user AH through:
cma_iboe_join_multicast
cma_make_mc_event
ib_init_ah_from_mcmember
And a random traffic_class causes a random IP DSCP in RoCEv2.

When the master device is unbinded, make sure to clean up all of the
steering rules or flow tables that were created over the master, in
order to allow proper unbinding of master, and for ethernet traffic
to continue to work independently.
Upon bringing master device back up and attaching the slave to it,
checks if the slave already has IPsec configured and if so reconfigure
the rules needed to support RoCE traffic.
Note that while master device is unbound, the user is unable to
configure IPsec again, since they are in a kind of illegal state in
which they are in MPV mode but the slave has no master.
However if IPsec was configured before hand, it will continue to work
for ethernet traffic while master is unbound, and would continue to
work for all traffic when the master is bound back again.

Add empty flow table in RDMA_RX master domain, to forward all received
traffic to it, in order to continue through the FW RoCE steering.
In order to achieve that however, first we check if the decrypted
traffic is RoCEv2, if so then forward it to RDMA_RX domain.
But in case the traffic is coming from the slave, have to first send the
traffic to an alias table in order to switch gvmi and from there we can
go to the appropriate gvmi flow table in RDMA_RX master domain.

Since commit 9bf19fbf0c8b ("media: v4l: async: Rework internal lists"), aka

recursion due tegra_vi_graph_parse_one() calling itself until:

[ 4.890770] host1x_video_probe from really_probe+0xe0/0x400
The reason is the mentioned commit changed tegra_vi_graph_find_entity() to
search for an entity in the done notifier list:
> @@ -1464,7 +1464,7 @@ tegra_vi_graph_find_entity(struct tegra_vi_channel *chan,
> struct tegra_vi_graph_entity *entity;
> struct v4l2_async_connection *asd;

> entity = to_tegra_vi_graph_entity(asd);
> if (entity->asd.match.fwnode == fwnode)
> return entity;
This is not always correct, being tegra_vi_graph_find_entity() called in
three locations, in this order:
1. tegra_vi_graph_parse_one() -- called while probing
2. tegra_vi_graph_notify_bound() -- the .bound notifier op
3. tegra_vi_graph_build() -- called in the .complete notifier op
Locations 1 and 2 are called before moving the entity from waiting_list to
done_list, thus they won't find what they are looking for in
done_list. Location 3 happens afterwards and thus it is not broken, however
it means tegra_vi_graph_find_entity() should not search in the same list
every time.
The error appears at step 1: tegra_vi_graph_parse_one() iterates
recursively until it finds the entity already notified, which now never
happens.
Fix by passing the specific notifier list pointer to
tegra_vi_graph_find_entity() instead of the channel, so each caller can
search in whatever list is correct.
Also improve the tegra_vi_graph_find_entity() comment.

The current Kconfig symbol dependencies allow having the following Kconfig
symbol values
CONFIG_IPU_BRIDGE=m
CONFIG_VIDEO_IPU3_CIO2=y
CONFIG_CIO2_BRIDGE=n
This does not work as the IPU bridge API is conditional to
IS_ENABLED(CONFIG_IPU_BRIDGE). Fix this by changing the dependencies so
that CONFIG_IPU_BRIDGE can be separately selected.
The CONFIG_CIO2_BRIDGE symbol becomes redundant as a result and is
removed.
