Jason mentioned at netdevconf that we've run out of tx_flags in
the skb_shinfo(). Gain one bit back by removing the wifi bit.
We can do that because the only userspace application for it
(hostapd) doesn't change the setting on the socket, it just
uses different sockets, and normally doesn't even use this any
more, sending the frames over nl80211 instead.

Merge series from João Paulo Gonçalves <jpaulo.silvagoncalves@gmail.com>:
I'm working on integrating a system with a MAX20086 and noticed these
small issues in the driver: the chip ID for MAX20086 is 0x30 and not
0x40. Also, in my use case, the enable pin is always enabled by
hardware, so the enable GPIO isn't needed. Without these changes, the
driver fails to probe.

For regular cpuidle states we are reflecting over the selected/entered
state to see if the sleep-duration meets the residency for the state. The
output from the reflection is an "above" value to indicate the number of
times the state was too deep and a "below" value for the number of times it
was too shallow.
Let's implement the similar thing for genpd's domain-idlestates along with
genpd's governor and put the information in the genpd's debugfs.

In the cpuidle-psci-domain case the ->power_off() callback is usually
returning zero to indicate success. This is because the actual call to the
PSCI FW to enter the selected domain-idlestate, needs to be done after the
->power_off() callback has returned.
When the call to the PSCI FW fails, this leads to receiving an incorrect
tracking of the usage/rejected counts for the selected domain-idlestate.
In other words, the presented debug-statistics for genpd may look better
than what the actually are.
To allow a better correctness of the data, let's add a new genpd helper
function, which enables the caller adjust the usage/rejected counters for a
domain-idlestate, in cases of errors during power-off.

pci_host_common_probe()
pci_host_common_probe() is an extremely useful helper, as it
abstracts away most of the gunk that a "mostly-ECAM-compliant"
device driver needs.
However, it is structured as a probe function, meaning that a lot
of the driver-specific setup has to happen in a .init() callback,
after the bridge and config space have been instantiated.
This is a bit awkward, and results in a number of convolutions
that could be avoided if the host-common code was more like
a library.
Introduce a pci_host_common_init() helper that does exactly that,
taking the platform device and a struct pci_ecam_op as parameters.
This can then be called from the probe routine, and a lot of the
code that isn't relevant to PCI setup moved away from the .init()
callback. This also removes the dependency on the device match
data, which is an oddity.

Provide an option to handle the partial blocks in the shash API.
Almost every hash algorithm has a block size and are only able
to hash partial blocks on finalisation.
Rather than duplicating the partial block handling many times,
add this functionality to the shash API.
It is optional (e.g., hmac would never need this by relying on
the partial block handling of the underlying hash), and to enable
it set the bit CRYPTO_AHASH_ALG_BLOCK_ONLY.
The export format is always that of the underlying hash export,
plus the partial block buffer, followed by a single-byte for the
partial block length.
Set the bit CRYPTO_AHASH_ALG_FINAL_NONZERO to withhold an extra
byte in the partial block. This will come in handy when this
is extended to ahash where hardware often can't deal with a
zero-length final.
It will also be used for algorithms requiring an extra block for
finalisation (e.g., cmac).
As an optimisation, set the bit CRYPTO_AHASH_ALG_FINUP_MAX if
the algorithm wishes to get as much data as possible instead of
just the last partial block.
The descriptor will be zeroed after finalisation.

Commit 03df156dd3a6 ("xdp: double protect netdev->xdp_flags with
netdev->lock") introduces the netdev lock to xdp_set_features_flag().
The change includes a _locked version of the method, as it is possible
for a driver to have already acquired the netdev lock before calling
this helper. However, the same applies to
xdp_features_(set|clear)_redirect_flags(), which ends up calling the
unlocked version of xdp_set_features_flags() leading to deadlocks in
GVE, which grabs the netdev lock as part of its suspend, reset, and
shutdown processes:

As a result of an email from the fbnic author, I reviewed the phylink
documentation, and I have decided to clarify the wording in the
mac_link_(up|down)() kernel documentation as this was written from the
point of view of mvneta/mvpp2 and is misleading.
The documentation talks about forcing the link - indeed, this is what
is done in the mvneta and mvpp2 drivers but not at the physical layer
but the MACs idea, which has the effect of only allowing or stopping
packet flow at the MAC. This "link" needs to be controlled when using
a PHY or fixed link to start or stop packet flow at the MAC. However,
as the MAC and PCS are tightly integrated, if the MACs idea of the
link is forced down, it has the side effect that there is no way to
determine that the media link has come up - in this mode, the MAC must
be allowed to follow its built-in PCS so we can read the link state.
Frame the documentation in more generic terms, to avoid the thought
that the physical media link to the partner needs in some way to be
forced up or down with these calls; it does not. If that were to be
done, it would be a self-fulfilling prophecy - e.g. if the media link
goes down, then mac_link_down() will be called, and if the media link
is then placed into a forced down state, there is no possibility
that the media link will ever come up again - clearly this is a wrong
interpretation.
These methods are notifications to the MAC about what has happened to
the media link state - either from the PHY, or a PCS, or whatever
mechanism fixed-link is using. Thus, reword them to get away from
talking about changing link state to avoid confusion with media link
state.
This is not a change of any requirements of these methods.
Also, remove the obsolete references to EEE for these methods, we now
have the LPI functions for configuring the EEE parameters which
renders this redundant, and also makes the passing of "phy" to the
mac_link_up() function obsolete.

There are a few use-cases where child nodes with a specific name need to
be parsed. Code like:
fwnode_for_each_child_node()
if (fwnode_name_eq())
...
can be found from a various drivers/subsystems. Adding a macro for this
can simplify things a bit.
In a few cases the data from the found nodes is later added to an array,
which is allocated based on the number of found nodes. One example of
such use is the IIO subsystem's ADC channel nodes, where the relevant
nodes are named as channel[@N].
Add helpers for iterating and counting device's sub-nodes with certain
name instead of open-coding this in every user.

The large folio + buffer head noref migration scenarios are
being naughty and blocking while holding a spinlock.
As a consequence of the pagecache lookup path taking the
folio lock this serializes against migration paths, so
they can wait for each other. For the private_lock
atomic case, a new BH_Migrate flag is introduced which
enables the lookup to bail.
This allows the critical region of the private_lock on
the migration path to be reduced to the way it was before
ebdf4de5642fb6 ("mm: migrate: fix reference check race
between __find_get_block() and migration"), that is covering
the count checks.
The scope is always noref migration.

p8022.c defines two external functions, register_8022_client()
and unregister_8022_client(), the last use of which was removed in
2018 by
commit 7a2e838d28cf ("staging: ipx: delete it from the tree")
Remove the p8022.c file, it's corresponding header, and glue
surrounding it. There was one place the header was included in vlan.c
but it didn't use the functions it declared.
There was a comment in net/802/Makefile about checking
against net/core/Makefile, but that's at least 20 years old and
there's no sign of net/core/Makefile mentioning it.

Now there are no users of the return value of the drm_panel_prepare(),
drm_panel_unprepare(), drm_panel_enable() and drm_panel_disable() calls.
Usually these calls are performed from the atomic callbacks, where it is
impossible to return an error. Stop returning error codes and return
void instead.

Add queue id support to the user queue wait IOCTL
drm_amdgpu_userq_wait structure.
This is required to retrieve the wait user queue and maintain
the fence driver references in it so that the user queue in
the same context releases their reference to the fence drivers
at some point before queue destruction.
Otherwise, we would gather those references until we
don't have any more space left and crash.
v2: Modify the UAPI comment as per the mesa and libdrm UAPI comment.
