If the AP removal timer is long, we don't really want to
remove the link immediately. However, we really should do
it _before_ the AP removes it (which happens at or after
count reaches 0), so subtract 1 from the countdown when
scheduling the timer. This causes the link removal work
to run just after the beacon with value 1 is received. If
the counter is already zero, do it immediately.
This fixes an issue where we do the removal too late and
receive a beacon from the AP that's no longer associated
with the MLD, but thus removed EHT and ML elements, and
then we disconnect instead from the whole MLD, since one
of the associated APs changed mode from EHT to HE.

If the AP mode ends up being determined less than the client mode,
there may be different reasons for this, e.g. AP misconfiguration.
If this happens in a way that causes e.g. EHT to be rejected, the
elements need to be re-parsed since we'll connect as HE, but not
reparsing means that we'll still think it's OK to use multi-link,
so we can connect in a non-sensical configuration of advertising
only HE on a secondary link. This normally won't happen for the
assoc link because that reuses the mode from authentication, and
if that's not EHT, multi-link association is rejected.
Fix this inconsistency by parsing the elements again if the mode
was different from the first parsing attempt. Print the message a
bit later to avoid printing "determined AP ... to be HE" twice in
cases where ieee80211_determine_ap_chan() returned a lesser mode,
rather than the regulatory downgrades below changing it.

When doing re-parsing in ieee80211_determine_chan_mode(),
the conn->mode is changed, and the whole point of doing
the parsing again was to parse as the downgraded mode.
However, that didn't actually work, because the setting

The qpl_cfg struct was used to make sure that no two different queues
are using QPL with the same qpl_id. We can remove that qpl_cfg struct
since now the qpl_ids map with the queues respectively as follows:
For tx queues: qpl_id = tx_qid
For rx queues: qpl_id = max_tx_queues + rx_qid
And when XDP is used, it will need the user to reduce the tx queues to
be at most half of the max_tx_queues. Then it will use the same number
of tx queues starting from the end of existing tx queues for XDP. So the
XDP queues will not exceed the max_tx_queues range and will not overlap
with the rx queues, where the qpl_ids will not have overlapping too.
Considering of that, we remove the qpl_cfg struct to get the qpl_id
directly based on the queue id. Unless we are erroneously allocating a
rx/tx queue that has already been allocated, we would never allocate
the qpl with the same qpl_id twice. In that case, it should fail much
earlier than the QPL assignment.

Integrate the regulator framework to the PSE framework for enhanced
access to features such as voltage, power measurement, and limits, which
are akin to regulators. Additionally, PSE features like port priorities
could potentially enhance the regulator framework. Note that this
integration introduces some implementation complexity, including wrapper
callbacks, but the potential benefits make it worthwhile.
Regulator are using enable counter with specific behavior.
Two calls to regulator_disable will trigger kernel warnings.
If the counter exceeds one, regulator_disable call won't disable the
PSE PI. These behavior isn't suitable for PSE control.
Added a boolean 'enabled' state to prevent multiple calls to
regulator_enable/disable. These calls will only be called from PSE
framework as it won't have any regulator children, therefore no mutex are
needed to safeguards this boolean.
regulator_get needs the consumer device pointer. Use PSE as regulator
provider and consumer device until we have RJ45 ports represented in
the Kernel.

PSE PI setup may encompass multiple PSE controllers or auxiliary circuits
that collectively manage power delivery to one Ethernet port.
Such configurations might support a range of PoE standards and require
the capability to dynamically configure power delivery based on the
operational mode (e.g., PoE2 versus PoE4) or specific requirements of
connected devices. In these instances, a dedicated PSE PI node becomes
essential for accurately documenting the system architecture. This node
would serve to detail the interactions between different PSE controllers,
the support for various PoE modes, and any additional logic required to
coordinate power delivery across the network infrastructure.
The old usage of "#pse-cells" is unsuficient as it carries only the PSE PI
index information.

The Power Sourcing Equipment Power Interface (PSE PI) plays a pivotal role
in the architecture of Power over Ethernet (PoE) systems. It is essentially
a blueprint that outlines how one or multiple power sources are connected
to the eight-pin modular jack, commonly known as the Ethernet RJ45 port.
This connection scheme is crucial for enabling the delivery of power
alongside data over Ethernet cables.
This patch adds support for getting the PSE controller node through PSE PI
device subnode.
This supports adds a way to get the PSE PI id from the pse_pi devicetree
subnode of a PSE controller node simply by reading the reg property.

In the current PSE interface for Ethernet Power Equipment, support is
limited to PoDL. This patch extends the interface to accommodate the
objects specified in IEEE 802.3-2022 145.2 for Power sourcing
Equipment (PSE).
The following objects are now supported and considered mandatory:
- IEEE 802.3-2022 30.9.1.1.5 aPSEPowerDetectionStatus
- IEEE 802.3-2022 30.9.1.1.2 aPSEAdminState
- IEEE 802.3-2022 30.9.1.2.1 aPSEAdminControl
To avoid confusion between "PoDL PSE" and "PoE PSE", which have similar
names but distinct values, we have followed the suggestion of Oleksij
Rempel and Andrew Lunn to maintain separate naming schemes for each,
using c33 (clause 33) prefix for "PoE PSE".

^^^^
It's a bit tempting to make the exit part of ksft_run(),
but that only works well for very trivial setups. We can
revisit this later, if people forget to call ksft_exit().

Even though the boot protocol stipulates otherwise, an exception has
been made for the EFI stub, and entering the core kernel with the MMU
enabled is permitted. This allows a substantial amount of cache
maintenance to be elided, wich is significant when fast boot times are
critical (e.g., for booting micro-VMs)
Once the initial ID map has been populated, the MMU is disabled as part
of the logic sequence that puts all system registers into a known state.
Any code that needs to execute within the window where the MMU is off is
cleaned to the PoC explicitly, which includes all of HYP text when
entering at EL2.
However, the current sequence of initializing the EL2 system registers
is not safe: HCR_EL2 is set to its nVHE initial state before SCTLR_EL2
is reprogrammed, and this means that a VHE-to-nVHE switch may occur
while the MMU is enabled. This switch causes some system registers as
well as page table descriptors to be interpreted in a different way,
potentially resulting in spurious exceptions relating to MMU
translation.
So disable the MMU explicitly first when entering in EL2 with the MMU
and caches enabled.

The Falkor erratum that results in the need for an ISB before clearing
the M bit in SCTLR_ELx only applies to execution at exception level x,
and so the workaround is not needed when disabling the EL1 MMU while

The TX and RX DMA Channels used by the driver to exchange data with CPSW
are not guaranteed to be in a clean state during driver initialization.
The Bootloader could have used the same DMA Channels without cleaning them
up in the event of failure. Thus, reset and disable the DMA Channels to
ensure that they are in a clean state before using them.

After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two
consecutive device resets"), reset operation, in which the default mac
address from the device is read, is not executed from bind operation and
the random address, that is pregenerated just in case, is direclty written
the first time in the device, so the default one from the device is not
even read. This writing is not dangerous because is volatile and the
default mac address is not missed.
In order to avoid this and keep the simplification to have only one
reset and reduce the delays, restore the reset from bind operation and
remove the reset that is commanded from open operation. The behavior is
the same but everything is ready for usbnet_probe.
Tested with ASIX AX88179 USB Gigabit Ethernet devices.
Restore the old behavior for the rest of possible devices because I don't
have the hardware to test.

Pull random number generator fixes from Jason Donenfeld:
- The input subsystem contributes entropy in some places where a
spinlock is held, but the entropy accounting code only handled
callers being in an interrupt or non-atomic process context, but not
atomic process context. We fix this by removing an optimization and
just calling queue_work() unconditionally.
- Greg accidently sent up a patch not intended for his tree and that

[BUG]
During my extent_map cleanup/refactor, with extra sanity checks,
extent-map-tests::test_case_7() would not pass the checks.
The problem is, after btrfs_drop_extent_map_range(), the resulted
extent_map has a @block_start way too large.
Meanwhile my btrfs_file_extent_item based members are returning a
correct @disk_bytenr/@offset combination.
The extent map layout looks like this:
0 16K 32K 48K
| PINNED | | Regular |
The regular em at [32K, 48K) also has 32K @block_start.
Then drop range [0, 36K), which should shrink the regular one to be
[36K, 48K).
However the @block_start is incorrect, we expect 32K + 4K, but got 52K.
[CAUSE]
Inside btrfs_drop_extent_map_range() function, if we hit an extent_map
that covers the target range but is still beyond it, we need to split
that extent map into half:
|<-- drop range -->|
|<----- existing extent_map --->|
And if the extent map is not compressed, we need to forward
extent_map::block_start by the difference between the end of drop range
and the extent map start.
However in that particular case, the difference is calculated using
(start + len - em->start).
The problem is @start can be modified if the drop range covers any
pinned extent.
This leads to wrong calculation, and would be caught by my later
extent_map sanity checks, which checks the em::block_start against
btrfs_file_extent_item::disk_bytenr + btrfs_file_extent_item::offset.
This is a regression caused by commit c962098ca4af ("btrfs: fix
incorrect splitting in btrfs_drop_extent_map_range"), which removed the
@len update for pinned extents.
[FIX]
Fix it by avoiding using @start completely, and use @end - em->start
instead, which @end is exclusive bytenr number.
And update the test case to verify the @block_start to prevent such
problem from happening.
Thankfully this is not going to lead to any data corruption, as IO path
does not utilize btrfs_drop_extent_map_range() with @skip_pinned set.
So this fix is only here for the sake of consistency/correctness.

Commit 4601b4b130de ("block: reopen the device in blkdev_reread_part")
lost the propagation of I/O errors from the low-level read of the
partition table to the user space caller of the BLKRRPART.
Apparently some user space relies on, so restore the propagation. This
isn't exactly pretty as other block device open calls explicitly do not
are about these errors, so add a new BLK_OPEN_STRICT_SCAN to opt into
the error propagation.

Fix cpuid_deps[] to list the correct dependencies for GFNI, VAES, and
VPCLMULQDQ. These features don't depend on AVX512, and there exist CPUs
that support these features but not AVX512. GFNI actually doesn't even
depend on AVX.
This prevents GFNI from being unnecessarily disabled if AVX is disabled
to mitigate the GDS vulnerability.
This also prevents all three features from being unnecessarily disabled
if AVX512VL (or its dependency AVX512F) were to be disabled, but it
looks like there isn't any case where this happens anyway.

The DWC3_EP_RESOURCE_ALLOCATED flag ensures that the resource of an
endpoint is only assigned once. Unless the endpoint is reset, don't
clear this flag. Otherwise we may set endpoint resource again, which
prevents the driver from initiate transfer after handling a STALL or
endpoint halt to the control endpoint.
