ASoC core code does not modify contents of 'of_phandle_args' in 'struct
snd_soc_dai_driver', so the pointer can be made as a pointer to const.
This makes code safer, serves as clear annotation of core's intentions
and allows putting pointed structures in rodata (if ever applicable).

Test the vesa_attributes field in struct screen_info for compatibility
with VGA hardware. Vesafb currently tests bit 1 in screen_info's
capabilities field which indicates a 64-bit lfb address and is
unrelated to VGA compatibility.
Section 4.4 of the Vesa VBE 2.0 specifications defines that bit 5 in
the mode's attributes field signals VGA compatibility. The mode is
compatible with VGA hardware if the bit is clear. In that case, the
driver can access VGA state of the VBE's underlying hardware. The
vesafb driver uses this feature to program the color LUT in palette
modes. Without, colors might be incorrect.
The problem got introduced in commit 89ec4c238e7a ("[PATCH] vesafb: Fix
incorrect logo colors in x86_64"). It incorrectly stores the mode
attributes in the screen_info's capabilities field and updates vesafb
accordingly. Later, commit 5e8ddcbe8692 ("Video mode probing support for
the new x86 setup code") fixed the screen_info, but did not update vesafb.
Color output still tends to work, because bit 1 in capabilities is
usually 0.
Besides fixing the bug in vesafb, this commit introduces a helper that
reads the correct bit from screen_info.

10G-QXGMII is a MAC-to-PHY interface defined by the USXGMII multiport
specification. It uses the same signaling as USXGMII, but it multiplexes
4 ports over the link, resulting in a maximum speed of 2.5G per port.
Some in-tree SoCs like the NXP LS1028A use "usxgmii" when they mean
either the single-port USXGMII or the quad-port 10G-QXGMII variant, and
they could get away just fine with that thus far. But there is a need to
distinguish between the 2 as far as SerDes drivers are concerned.

This declaration was added to the header to be called from ethtool.
ethtool is separated from core for code organization but it is not really
a separate entity, it controls very core things.
As ethtool is an internal stuff it is not wise to have it in netdevice.h.
Move the declaration to net/core/dev.h instead.
Remove the EXPORT_SYMBOL_GPL call as ethtool can not be built as a module.

When an SVSM is present, the guest can also request attestation reports
from it. These SVSM attestation reports can be used to attest the SVSM
and any services running within the SVSM.
Extend the config-fs attestation support to provide such. This involves
creating four new config-fs attributes:
- 'service-provider' (input)
This attribute is used to determine whether the attestation request
should be sent to the specified service provider or to the SEV
firmware. The SVSM service provider is represented by the value
'svsm'.
- 'service_guid' (input)
Used for requesting the attestation of a single service within the
service provider. A null GUID implies that the SVSM_ATTEST_SERVICES
call should be used to request the attestation report. A non-null
GUID implies that the SVSM_ATTEST_SINGLE_SERVICE call should be used.
- 'service_manifest_version' (input)
Used with the SVSM_ATTEST_SINGLE_SERVICE call, the service version
represents a specific service manifest version be used for the
attestation report.
- 'manifestblob' (output)
Used to return the service manifest associated with the attestation
report.
Only display these new attributes when running under an SVSM.

MADT Multiprocessor Wakeup structure version 1 brings support for CPU offlining:
BIOS provides a reset vector where the CPU has to jump to for offlining itself.
The new TEST mailbox command can be used to test whether the CPU offlined itself
which means the BIOS has control over the CPU and can online it again via the
ACPI MADT wakeup method.
Add CPU offlining support for the ACPI MADT wakeup method by implementing custom
cpu_die(), play_dead() and stop_this_cpu() SMP operations.
CPU offlining makes it possible to hand over secondary CPUs over kexec, not
limiting the second kernel to a single CPU.
The change conforms to the approved ACPI spec change proposal. See the Link.

Rename 'mailbox_version' to 'version'. This field signifies the version of the
structure and the related protocols, rather than the version of the mailbox.
This field has not been utilized in the code thus far.
Rename 'base_address' to 'mailbox_address' to clarify the kind of address it
represents. In version 1, the structure includes the reset vector address. Clear

The current API functions create an irq_domain and also publish this
newly created to domain. Once an irq_domain is published, consumers can
request IRQ in order to use them.
Some interrupt controller drivers have to perform some more operations
with the created irq_domain in order to have it ready to be used.
For instance:
- Allocate generic irq chips with irq_alloc_domain_generic_chips()
- Retrieve the generic irq chips with irq_get_domain_generic_chip()
- Initialize retrieved chips: set register base address and offsets,
set several hooks such as irq_mask, irq_unmask, ...
With the newly introduced irq_domain_alloc_generic_chips(), an interrupt
controller driver can use the irq_domain_chip_generic_info structure and
set the init() hook to perform its generic chips initialization.
In order to avoid a window where the domain is published but not yet
ready to be used, handle the generic chip creation (i.e the
irq_domain_alloc_generic_chips() call) before the domain is published.

/* create v4 smc sock */
v4 = socket(AF_INET, SOCK_STREAM, IPPROTO_SMC);
/* create v6 smc sock */
v6 = socket(AF_INET6, SOCK_STREAM, IPPROTO_SMC);
There are several reasons why we believe it is appropriate here:
1. For smc sockets, it actually use IPv4 (AF-INET) or IPv6 (AF-INET6)
address. There is no AF_SMC address at all.
2. Create smc socket in the AF_INET(6) path, which allows us to reuse
the infrastructure of AF_INET(6) path, such as common ebpf hooks.
Otherwise, smc have to implement it again in AF_SMC path.

I find the behavior of xa_for_each_start() slightly counter-intuitive.
It doesn't end the iteration by making the index point after the last
element. IOW calling xa_for_each_start() again after it "finished"
will run the body of the loop for the last valid element, instead
of doing nothing.
This works fine for netlink dumps if they terminate correctly
(i.e. coalesce or carefully handle NLM_DONE), but as we keep getting
reminded legacy dumps are unlikely to go away.
Fixing this generically at the xa_for_each_start() level seems hard -
there is no index reserved for "end of iteration".
ifindexes are 31b wide, tho, and iterator is ulong so for
for_each_netdev_dump() it's safe to go to the next element.

'struct mtk_adsp_ipc_ops' is not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.
In order to do it, "struct mtk_adsp_ipc" also needs to be adjusted to this
new const qualifier.

This patch is for for-next branch.
The selfIDComplete event occurs in the bus managed by one of 1394 OHCI
controller in Linux system, while the existing tracepoints events has
the lack of data about it to distinguish the issued hardware from the
others.
This commit adds card_index member into event structure to store the index
of host controller in use, and prints it.

It is helpful to trace the content of self ID sequence when the core
function building bus topology.
This commit adds a tracepoints event fot the purpose. It seems not to
achieve printing variable length of array in print time without any
storage, thus the structure of event includes a superfluous array to store
the state of port. Additionally, there is no helper function to print
symbol array, thus the state of port is printed as raw value.

It is a bit inconvenient to put the relative path to local header from
tree-wide header.
This commit delegates the selection to include headers into users.

The work flags can be set/accessed from different tasks, both the
originator of the request, and the io-wq workers. While modifications
aren't concurrent, it still makes KMSAN unhappy. There's no real
downside to just making the flag reading/manipulation use proper
atomics here.

This is pretty nicely abstracted already, but let's move it to a separate
file rather than have it in the main io_uring file. With that, we can
also move the io_ev_fd struct and enum out of global scope.

- removal of devm_device_add_groups(), all the callers of this are
finally gone after the 6.10-rc1 merge (changes came in through
different trees), so it's safe to remove.
- much reported sysfs build error fixed up for systems that did not
have sysfs enabled
- driver core sync issue fix for a many reported issue over the years
that no one really paid much attention to, until Dirk finally
tracked down the real issue and made the "obviously correct and
simple" fix for it.
