Drop kvm_arch_{start,end}_assignment() and all associated code now that
KVM x86 no longer consumes assigned_device_count. Tracking whether or not
a VFIO-assigned device is formally associated with a VM is fundamentally
flawed, as such an association is optional for general usage, i.e. is prone
to false negatives. E.g. prior to commit 2edd9cb79fb3 ("kvm: detect
assigned device via irqbypass manager"), device passthrough via VFIO would
fail to enable IRQ bypass if userspace omitted the formal VFIO<=>KVM
binding.
And device drivers that *need* the VFIO<=>KVM connection, e.g. KVM-GT,
shouldn't be relying on generic x86 tracking infrastructure.

Current Kconfig menu at [ALSA for SoC audio support] has no rules.
So, some venders are using menu style, some venders are listed each drivers

The sev_data_snp_launch_start structure should include a 4-byte
desired_tsc_khz field before the gosvw field, which was missed in the
initial implementation. As a result, the structure is 4 bytes shorter than
expected by the firmware, causing the gosvw field to start 4 bytes early.
Fix this by adding the missing 4-byte member for the desired TSC frequency.

gs101 differs to other currently supported SoCs in that it has 3 wakeup
mask registers for the 67 external wakeup interrupt pins in alive and
far_alive.
EINT_WAKEUP_MASK 0x3A80 EINT[31:0]
EINT_WAKEUP_MASK2 0x3A84 EINT[63:32]
EINT_WAKEUP_MASK3 0x3A88 EINT[66:64]
Add gs101 specific callbacks and a dedicated gs101_wkup_irq_chip struct to
handle these differences.
The current wakeup mask with upstream is programmed as
WAKEUP_MASK0[0x3A80] value[0xFFFFFFFF]
WAKEUP_MASK1[0x3A84] value[0xF2FFEFFF]
WAKEUP_MASK2[0x3A88] value[0xFFFFFFFF]
Which corresponds to the following wakeup sources:
gpa7-3 vol down
gpa8-1 vol up
gpa10-1 power
gpa8-2 typec-int

Currently the sdw machine driver uses different way to get the
component name from the DAI name for different codecs in the rtd_init
callback. It means that we need to rely on the rtd_init callback to get
the component name. Add an optional component string to the
asoc_sdw_dai_info struct allows the machine driver to get the component
name directly.
The commit adds the component names for the AMP dais for the preparation
to set card->components string for combined speaker configs.

There is a PPU0 reset control bit in the same register as the PPU1
reset control. This missing reset control is for the PCK-600 unit
in the SoC. Manual tests show that the reset control indeed exists,
and if not configured, the system will hang when the PCK-600 registers
are accessed.
Add a reset entry for it at the end of the existing ones.

Currently in ib_free_cq, it disables IRQ or cancel the CQ work before
driver destroy_cq. This isn't good as a new IRQ or a CQ work can be
submitted immediately after disabling IRQ or canceling CQ work, which
may run concurrently with destroy_cq and cause crashes.
The right flow should be:
1. Driver disables CQ to make sure no new CQ event will be submitted;
2. Disables IRQ or Cancels CQ work in core layer, to make sure no CQ
polling work is running;
3. Free all resources to destroy the CQ.
This patch adds 2 driver APIs:
- pre_destroy_cq(): Disable a CQ to prevent it from generating any new
work completions, but not free any kernel resources;
- post_destroy_cq(): Free all kernel resources.
In ib_free_cq, the IRQ is disabled or CQ work is canceled after
pre_destroy_cq, and before post_destroy_cq.

Currently, the in-kernel kunit test case timeout is 300 seconds. (There
is a separate timeout mechanism for the whole test execution in
kunit.py, but that's unrelated.) However, tests marked 'slow' or 'very
slow' may timeout, particularly on slower machines.
Implement a multiplier to the test-case timeout, so that slower tests
have longer to complete:
- DEFAULT -> 1x default timeout
- KUNIT_SPEED_SLOW -> 3x default timeout
- KUNIT_SPEED_VERY_SLOW -> 12x default timeout
A further change is planned to allow user configuration of the
default/base timeout to allow people with faster or slower machines to
adjust these to their use-cases.

UBLK_F_SUPPORT_ZERO_COPY has a very old comment describing the initial
idea for how zero-copy would be implemented. The actual implementation
added in commit 1f6540e2aabb ("ublk: zc register/unregister bvec") uses
io_uring registered buffers rather than shared memory mapping.
Remove the inaccurate remarks about mapping ublk request memory into the
ublk server's address space and requiring 4K block size. Replace them
with a description of the current zero-copy mechanism.

The only reason why alpha can't do what sparc et.al. are doing
is that include/asm-generic/param.h relies upon the value of HZ
set for userland header in uapi/asm/param.h being 100.
We need that value to define USER_HZ and we need that definition
to outlive the redefinition of HZ kernel-side. And alpha needs
it to be 1024, not 100 like everybody else.
So let's add __USER_HZ to uapi/asm-generic/param.h, defaulting to
100 and used to define HZ. That way include/asm-generic/param.h
can use that thing instead of open-coding it - it won't be affected
by undefining and redefining HZ.
That done, alpha asm/param.h can be removed and uapi/asm/param.h
switched to defining __USER_HZ and EXEC_PAGESIZE and then including
<asm-generic/param.h> - asm/param.h will resolve to uapi/asm/param.h,
which pulls <asm-generic/param.h>, which will do the right thing
both in the kernel and userland contexts.

For systems using a sched_ext scheduler and has panic_on_rcu_stall
enabled, try kicking out the current scheduler before issuing a panic.
While there are numerous reasons for RCU CPU stalls that are not
directly attributed to the scheduler, deferring the panic gives
sched_ext an opportunity to provide additional debug info when ejecting
the current scheduler. Also, handling the event more gracefully allows
us to potentially recover the system instead of incurring additional
down time.

Like s390 and the jailhouse hypervisor, LoongArch's PCI architecture allows
passing isolated PCI functions to a guest OS instance. So it is possible
that there is a multi-function device without function 0 for the host or
guest.
Allow probing such functions by adding a IS_ENABLED(CONFIG_LOONGARCH) case
in the hypervisor_isolated_pci_functions() helper.
This is similar to commit 189c6c33ff42 ("PCI: Extend isolated function

block_write_end() looks like it can be used as a ->write_end()
implementation. However, it can't as it does not unlock nor put
the folio. Since it does not use the 'file', 'mapping' nor 'fsdata'
arguments, remove them.

In case of multi-radio wiphys, with per-radio RTS threshold brought
into use, RTS threshold for each radio in a wiphy can be recorded in
wiphy parameter - wiphy_radio_cfg, as an array. Add a new attribute -
NL80211_WIPHY_RADIO_ATTR_RTS_THRESHOLD in nested parameter -
NL80211_ATTR_WIPHY_RADIOS. When a request for getting RTS threshold
for a particular radio is received, parse the radio id and get the
required data. Add this data to the newly added nested attribute
NL80211_WIPHY_RADIO_ATTR_RTS_THRESHOLD. Add support to report this
data to userspace.

Currently, setting RTS threshold is based on per-phy basis, i.e., all the
radios present in a wiphy will take RTS threshold value to be the one sent
from userspace. But each radio in a multi-radio wiphy can have different
RTS threshold requirements.
To extend support to set RTS threshold for each radio, get the radio for
which RTS threshold needs to be changed from the user. Use the attribute
in NL - NL80211_ATTR_WIPHY_RADIO_INDEX, to identify the radio of interest.
Create a new structure - wiphy_radio_cfg and add rts_threshold in it as a
u32 value to store RTS threshold of each radio in a wiphy and allocate
memory for it during wiphy register based on the wiphy.n_radio updated by
drivers. Pass radio id received from the user to mac80211 drivers along
with its corresponding RTS threshold.

Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

Currently, link station statistics for MLO are filled by mac80211.
But there are some statistics that kept by mac80211 might not be
accurate, so let the driver pre-fill the link statistics. The driver
can fill the values (indicating which field is filled, by setting the
filled bitmapin in link_station structure).
Statistics that driver don't fill are filled by mac80211.
Hence, add link_sta_statistics callback to fill link station statistics
for MLO in sta_set_link_sinfo() by drivers.

Currently, sinfo structure is supported to fill information at
deflink( or one of the links) level for station. This has problems
when applied to fetch multi-link(ML) station information.
Hence, if valid_links are present, support filling link_station
structure for each link.
This will be helpful to check the link related statistics during MLO.
Additionally, TXQ stats for pertid are applicable at station level
not at link level. Therefore check link_id is less then 0, before
filling TXQ stats in pertid stats.

Currently, station_info structure is passed to fill station statistics
from mac80211/drivers. After NL message send to user space for requested
station statistics, memory for station statistics is freed in cfg80211.
Therefore, memory allocation/free for link station statistics should
also happen in cfg80211 only.
Hence, allocate the memory for link_station structure for all
possible links and free in cfg80211_sinfo_release_content().

Current implementation of NL80211_GET_STATION does not work for
multi-link operation(MLO) since in case of MLO only deflink (or one
of the links) is considered and not all links.
Therefore to support for MLO, add link_station_info structure
to account link level statistics for station.
Additionally, add valid_links in station_info structure to indicate
bitmap of valid links for MLO. This will be helpful to check the link
related statistics during MLO.

Currently, in supporting API's to fill sinfo structure from sta
structure, is mapped to fill the fields from sta->deflink. However,
for multi-link (ML) station, sinfo structure should be filled from
corresponding link_id.
Therefore, add link_id as an additional argument in supporting API's
for filling sinfo structure correctly. Link_id is set to -1 for non-ML
station and corresponding link_id for ML stations. In supporting API's
for filling sinfo structure, check for link_id, if link_id < 0, fill
the sinfo structure from sta->deflink, otherwise fill from
sta->link[link_id].
Current, changes are done at the deflink level i.e, pass -1 as link_id.
Actual link_id will be added in subsequent patches to support
station statistics for MLO.

The symbol names in the .modinfo section are never used and already
randomized by the __UNIQUE_ID() macro.
Therefore, the second parameter of __MODULE_INFO() is meaningless
and can be removed to simplify the code.
With this change, the symbol names in the .modinfo section will be
prefixed with __UNIQUE_ID_modinfo, making it clearer that they
originate from MODULE_INFO().

Improve the setup_pi_matrix callback documentation to clarify its purpose
and usage. The enhanced description explains that PSE PI devicetree nodes
are pre-parsed before this callback is invoked, and drivers should utilize
pcdev->pi[x]->pairset[y].np to map PSE controller hardware ports to their
corresponding Power Interfaces.
This clarification helps driver implementers understand the callback's
role in establishing the hardware-to-PI relationship mapping.

Add support for 802.3cd based interface types 50GBASE-R and 100GBASE-P.
This choice in naming is based on section 135 of the 802.3-2022 IEEE
Standard.
In addition it is adding support for what I am referring to as LAUI
which is based on annex 135C of the IEEE Standard, and shares many
similarities with the 25/50G consortium. The main difference between the
two is that IEEE spec refers to LAUI as the AUI before the RS(544/514) FEC,
whereas the 25/50G use this lane and frequency combination after going
through RS(528/514), Base-R or no FEC at all.

Difference between sock_i_uid() and sk_uid() is that
after sock_orphan(), sock_i_uid() returns GLOBAL_ROOT_UID
while sk_uid() returns the last cached sk->sk_uid value.
None of sock_i_uid() callers care about this.
Use sk_uid() which is much faster and inlined.
Note that diag/dump users are calling sock_i_ino() and
can not see the full benefit yet.
