We have the server interface list hanging off the tcon
structure today for reasons unknown. So each tcon which is
connected to a file server can query them separately,
which is really unnecessary. To avoid this, in the query
function, we will check the time of last update of the
interface list, and avoid querying the server if it is
within a certain range.

The logic in efi_random_alloc() will iterate over the memory map twice,
once to count the number of candidate slots, and another time to locate
the chosen slot after randomization.
If there is insufficient memory to do the allocation, the second loop
will run to completion without actually having located a slot, but we
currently return EFI_SUCCESS in this case, as we fail to initialize
status to the appropriate error value of EFI_OUT_OF_RESOURCES.

S2idle resume freeze can be observed on Intel ADL + AMD WX5500. This is

[Why]
For engines not supporting soft reset, i.e. VCN, there will be a failed
ib test before mode 1 reset during asic reset. The fences in this case
are never signaled and next time when we try to free the sa_bo, kernel
will hang.
[How]
During pre_asic_reset, driver will clear job fences and afterwards the
fences' refcount will be reduced to 1. For drm_sched_jobs it will be
released in job_free_cb, and for non-sched jobs like ib_test, it's meant
to be released in sa_bo_free but only when the fences are signaled. So
we have to force signal the non_sched bad job's fence during
pre_asic_reset or the clear is not complete.

In some cases, we expose the kernel's struct screen_info to the EFI stub
directly, so it gets populated before even entering the kernel. This
means the early console is available as soon as the early param parsing
happens, which is nice. It also means we need two different ways to pass
this information, as this trick only works if the EFI stub is baked into
the core kernel image, which is not always the case.
Huacai reports that the preparatory refactoring that was needed to
implement this alternative method for zboot resulted in a non-functional
efifb earlycon for other cases as well, due to the reordering of the
kernel image relocation with the population of the screen_info struct,
and the latter now takes place after copying the image to its new
location, which means we copy the old, uninitialized state.
So let's ensure that the same-image version of alloc_screen_info()
produces the correct screen_info pointer, by taking the displacement of
the loaded image into account.

net: Allow changing IPv4 address protocol
IPv4 and IPv6 addresses can be assigned a protocol value that indicates the
provenance of the IP address. The attribute is modeled after ip route
protocols, and essentially allows the administrator or userspace stack to
tag addresses in some way that makes sense to the actor in question.
When IP address protocol field was added in commit 47f0bd503210 ("net: Add
new protocol attribute to IP addresses"), the semantics included the
ability to change the protocol for IPv6 addresses, but not for IPv4
addresses. It seems this was not deliberate, but rather by accident.
One particular use case is tagging the addresses differently depending on
whether the routing stack should advertise them or not. Without support for
protocol replacement, this can not be done.
In this patchset, extend IPv4 to allow changing the protocol defined at an
address (in patch #1). Then in patches #2 and #3 add selftest coverage for
ip address protocols.
Currently the kernel simply ignores the new value. Thus allowing the
replacement changes the observable behavior. However, since IPv6 already
behaves like this anyway, and since the feature as such is relatively new,
it seems like the change is safe to make.
An example session with the feature in action:
bash-5.2# ip address add dev d 192.0.2.1/28 proto 0xab
bash-5.2# ip address show dev d
4: d: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 06:29:74:fd:1f:eb brd ff:ff:ff:ff:ff:ff
inet 192.0.2.1/28 scope global proto 0xab d
valid_lft forever preferred_lft forever
bash-5.2# ip address replace dev d 192.0.2.1/28 proto 0x11
bash-5.2# ip address show dev d
4: d: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 06:29:74:fd:1f:eb brd ff:ff:ff:ff:ff:ff

ability to change the protocol for IPv6 addresses, but not for IPv4
addresses. It seems this was not deliberate, but rather by accident.
A userspace that wants to change the protocol of an address might drop and
recreate the address, but that disrupts routing and is just impractical.
So in this patch, when an IPv4 address is replaced (through RTM_NEWADDR
request with NLM_F_REPLACE flag), update the proto at the address to the
one given in the request, or zero if none is given. This matches the
behavior of IPv6. Previously, any new value given was simply ignored.

When requesting a TX queue at a given index, warn on out-of-bounds
referencing if the index is greater than the allocated number of
queues.
Specifically, since this function is used heavily in the networking
stack use DEBUG_NET_WARN_ON_ONCE to avoid executing a new branch on
every packet.

When setting the XPS value of a TX queue, warn the user once if the
index of the queue is greater than the number of allocated TX queues.
Previously, this scenario went uncaught. In the best case, it resulted
in unnecessary allocations. In the worst case, it resulted in
out-of-bounds memory references through calls to `netdev_get_tx_queue(
dev, index)`. Therefore, it is important to inform the user but not
worth returning an error and risk downing the netdevice.

====================
Add CPSWxG SGMII support for J7200 and J721E
This series adds support to configure the CPSW Ethernet Switch in SGMII
mode, using the am65-cpsw-nuss driver. SGMII mode is supported by the
CPSWxG instances on TI's J7200 and J721E SoCs. Thus, SGMII mode is added
in the list of extra_modes for the appropriate compatibles corresponding
to the aforementioned SoCs.
Additionally, the method of setting the supported interface via struct
"phylink_config" is simplified by converting the IF/ELSE statements to
SWITCH statements.

TI's J721E SoC supports SGMII mode with the CPSW9G instance of the CPSW
Ethernet Switch. Thus, enable it by adding SGMII mode to the extra_modes
member of the "j721e_cpswxg_pdata" SoC data.

Add support for configuring the CPSW Ethernet Switch in SGMII mode.
Depending on the SoC, allow selecting SGMII mode as a supported interface,
based on the compatible used.

Convert the existing IF/ELSE statement based approach of setting the
supported_interfaces member of struct "phylink_config", to SWITCH
statements. This will help scale to newer PHY-MODES as well as newer
compatibles.

Move setting the ssc_delta variable to under the PHY_INTERFACE_MODE_TRGMII
case as it's only needed when trgmii is used.

Move lowering the TRGMII Tx clock driving to mt7530_setup(), after setting
the core clock, as seen on the U-Boot MediaTek ethernet driver.
Move the code which looks like it lowers the TRGMII Rx clock driving to
after the TRGMII Tx clock driving is lowered. This is run after lowering
the Tx clock driving on the U-Boot MediaTek ethernet driver as well.
This way, the switch should consume less power regardless of port 6 being
used.
Update the comment explaining mt7530_pad_clk_setup().
Tested rgmii and trgmii modes of port 6 and rgmii mode of port 5 on MCM
MT7530 on MT7621AT Unielec U7621-06 and standalone MT7530 on MT7623NI
Bananapi BPI-R2.
