Sometimes setting up a DisplayPort tunnel may take quite long time. The
reason is that the graphics driver (DPRX) is expected to issue read of
certain monitor capabilities over the AUX channel and the "suggested"
timeout from VESA is 5 seconds. If there is no graphics driver loaded
this does not happen and currently we timeout and tear the tunnel down.
The reason for this is that at least Intel discrete USB4 controllers do
not send plug/unplug events about whether the DisplayPort cable from the
GPU to the controller is connected or not, so in order to "release" the
DisplayPort OUT adapter (the one that has monitor connected) we must
tear the tunnel down after this timeout has been elapsed.
In typical cases there is always graphics driver loaded, and also all
the cables are connected but for instance in Intel graphics CI they only
load the graphics driver after the system is fully booted up. This
makes the driver to tear down the DisplayPort tunnel. To help this case
we allow passing bigger or indefinite timeout through a new module
parameter (dprx_timeout). To keep the driver bit more responsive during
that time we change the way DisplayPort tunnels get activated. We first
do the normal tunnel setup and then run the polling of DPRX capabilities
read completion in a separate worker. This also makes the driver to
accept bandwidth requests to already established DisplayPort tunnels
more responsive.
If the tunnel still fails to establish we will tear it down and remove
the DisplayPort IN adapter from the dp_resource list to avoid using it
again (unless we get hotplug to that adapter).

Rework to avoid the goto as it only makes it confusing. Move logging to
happen at the end so we can see all the tunnels this is being called.

Since we are going to call this also when DisplayPort tunnel

It is pretty much the same as tb_tunnel_activate() excepts does check
for already activated paths. This is not needed anymore and makes it
more streamlined so drop tb_tunnel_restart() in favour of
tb_tunnel_activate().

The way these are called is not exactly symmetric as it is supposed to
be: the former is called when tunnel is being activated and the latter
is called when it is being released (not when it is being de-activated).
Furthermore host-to-host (DMA) tunnels are abusing the ->deinit hook to
clear out the credits. This makes it quite hard to follow what is being
called and when.
For these reasons rework the two "init" hooks to be called symmetrically
and rename them accordingly. For the DMA one, add a new hook that is
specifically used to run clean up for the tunnel when its memory is
being released.

Some graphics drivers such as i915 support runtime power management and
if there is nothing connected at the moment they will runtime suspend to
save power. At least i915 is polling for new connections every 10
seconds if the hardware does support sending PME. To allow i915 and
other graphics from detect the just established DisplayPort tunnel allow
the DPRX capabilities read to take up to 12 seconds.

Return value of ipmi_destroy_user() has no meaning, because it's always
zero and callers can do nothing with it. And in most cases it's not
checked. So make this function return void. This also will eliminate static
code analyzer warnings such as unreachable code/redundant comparison when
the return value is checked against non-zero value.

ipc_mmio_init() used the post-decrement operator in its loop continuing
condition of "retries" counter being "> 0", which meant that when this
condition caused loop exit "retries" counter reached -1.
But the later valid exec stage failure check only tests for "retries"
counter being exactly zero, so it didn't trigger in this case (but
would wrongly trigger if the code reaches a valid exec stage in the
very last loop iteration).
Fix this by using the pre-decrement operator instead, so the loop counter
is exactly zero on valid exec stage failure.

In efx_tc_ct_zone_ht_params, the key_len was previously set to
offsetof(struct efx_tc_ct_zone, linkage). This calculation is incorrect
because it includes any padding between the zone field and the linkage
field due to structure alignment, which can vary between systems.
This patch updates key_len to use sizeof_field(struct efx_tc_ct_zone, zone)
, ensuring that the hash table correctly uses the zone as the key. This fix
prevents potential hash lookup errors and improves connection tracking
reliability.

Add support to handle port channel RSCN.
Port channel RSCN is a Cisco vendor specific RSCN event. It is applicable
only to Cisco UCS fabrics. If there's a change in the port channel
configuration, an RCSN is sent to fnic. This is used to serially reset the
scsi initiator fnics so that there's no all paths down scenario. The
affected fnics are added to a list that are reset with a small time gap
between them.

Sending host information to shost_printk() prior to host initialization in
fnic is unnecessary. Replace shost_printk() and a printk() prior to this
initialization with dev_info() and dev_err() accordingly.

In cxl_dvsec_rr_decode() the pci driver expects to retrieve a cxlds,
struct cxl_dev_state, from the driver_data field of struct device.
While that works for Type 3, drivers for Type 1/2 devices may not
put a cxlds in the driver_data field.
In preparation for supporting Type 1/2 devices, replace parameter
'struct device' with 'struct cxl_dev_state' in cxl_dvsec_rr_decode().
Remove the unused parameter 'cxl_port' in cxl_dvsec_rr_decode().

The HMAT messages printed at boot, beyond being noisy, can also print
details for nodes that are not yet enabled. The primary method to
consume HMAT details is via sysfs, and the sysfs interface gates what is
emitted by whether the node is online or not. Hide the messages by
default by moving them from "info" to "debug" log level.
Otherwise, these prints are just a pretty-print way to dump the ACPI
HMAT table. It has always been the case that post-analysis was required
for these messages to map proximity-domains to Linux NUMA nodes, and as
Priya points out that analysis also needs to consider whether the
proximity domain is marked "enabled" in the SRAT.

The sysfs core now allows instances of 'struct bin_attribute' to be
moved into read-only memory. Make use of that to protect them against
accidental or malicious modifications.
