When userspace writes to the MII_ADVERTISE register, we update phylib's
advertising mask and trigger a renegotiation. However, writing to the
MII_CTRL1000 register, which contains the gigabit advertisement, does
neither. This can lead to phylib's copy of the advertisement becoming
de-synced with the values in the PHY register set, which can result in
incorrect negotiation resolution.

Pull copy_struct_from_user() helper from Christian Brauner:
"This contains the copy_struct_from_user() helper which got split out
from the openat2() patchset. It is a generic interface designed to
copy a struct from userspace.
The helper will be especially useful for structs versioned by size of
which we have quite a few. This allows for backwards compatibility,
i.e. an extended struct can be passed to an older kernel, or a legacy
struct can be passed to a newer kernel. For the first case (extended
struct, older kernel) the new fields in an extended struct can be set
to zero and the struct safely passed to an older kernel.
The most obvious benefit is that this helper lets us get rid of
duplicate code present in at least sched_setattr(), perf_event_open(),
and clone3(). More importantly it will also help to ensure that users
implementing versioning-by-size end up with the same core semantics.
This point is especially crucial since we have at least one case where
versioning-by-size is used but with slighly different semantics:
sched_setattr(), perf_event_open(), and clone3() all do do similar
checks to copy_struct_from_user() while rt_sigprocmask(2) always
rejects differently-sized struct arguments.
With this pull request we also switch over sched_setattr(),
perf_event_open(), and clone3() to use the new helper"

This sync_state driver/bus callback is called once all the consumers
of a supplier have probed successfully.
This allows the supplier device's driver/bus to sync the supplier
device's state to the software state with the guarantee that all the
consumers are actively managing the resources provided by the supplier
device.
To maintain backwards compatibility and ease transition from existing
frameworks and resource cleanup schemes, late_initcall_sync is the
earliest when the sync_state callback might be called.
There is no upper bound on the time by which the sync_state callback
has to be called. This is because if a consumer device never probes,
the supplier has to maintain its resources in the state left by the
bootloader. For example, if the bootloader leaves the display
backlight at a fixed voltage and the backlight driver is never probed,
you don't want the backlight to ever be turned off after boot up.
Also, when multiple devices are added after kernel init, some
suppliers could be added before their consumer devices get added. In
these instances, the supplier devices could get their sync_state
callback called right after they probe because the consumers devices
haven't had a chance to create device links to the suppliers.
To handle this correctly, this change also provides APIs to
pause/resume sync state callbacks so that when multiple devices are
added, their sync_state callback evaluation can be postponed to happen
after all of them are added.

The firmware corresponding to a device (dev.fwnode) might be able to
provide functional dependency information between a device and its
supplier and consumer devices. Tracking this functional dependency
allows optimizing device probe order and informing a supplier when all
its consumers have probed (and thereby actively managing their
resources).
The existing device links feature allows tracking and using
supplier-consumer relationships. So, this patch adds the add_links()
fwnode callback to allow firmware to create device links for each
device as the device is added.
However, when consumer devices are added, they might not have a supplier
device to link to despite needing mandatory resources/functionality from
one or more suppliers. A waiting_for_suppliers list is created to track
such consumers and retry linking them when new devices get added.

When algif_skcipher does a partial operation it always process data
that is a multiple of blocksize. However, for algorithms such as
CTR this is wrong because even though it can process any number of
bytes overall, the partial block must come at the very end and not
in the middle.
This is exactly what chunksize is meant to describe so this patch
changes blocksize to chunksize.

There really is no need to make drivers call the
ieee80211_start_tx_ba_cb_irqsafe() function and then
schedule the worker if all we want is to set a bit.
Add a new return value (that was previously considered
invalid) to indicate that the driver is immediately
ready for the session, and make drivers use it. The
only drivers that remain different are the Intel ones
as they need to negotiate more with the firmware.

This commit documents the expectation for NL80211_ATTR_IE when included
in NL80211_CMD_CONNECT, as following.
Driver shall not modify the IEs specified through NL80211_ATTR_IE if
NL80211_ATTR_MAC is included. However, if NL80211_ATTR_MAC_HINT is
included, these IEs through NL80211_ATTR_IE are specified by the user
space based on the best possible BSS selected. Thus, if the driver ends
up selecting a different BSS, it can modify these IEs accordingly (e.g.
userspace asks the driver to perform PMKSA caching with BSS1 and the
driver ends up selecting BSS2 with different PMKSA cache entry. RSNIE

Maintaining tpg_list without ever iterating over it is not useful. Hence
remove tpg_list. This patch does not change the behavior of the SCSI target
code.

When a non-passthrough command is terminated with CHECK CONDITION, request
sense is executed by hijacking the command descriptor. Since
scsi_eh_prep_cmnd() and scsi_eh_restore_cmnd() do not save/restore the
original command resid, the value returned on failure of the original
command is lost and replaced with the value set by the execution of the
request sense command. This value may in many instances be unaligned to the
device sector size, causing sd_done() to print a warning message about the
incorrect unaligned resid before the command is retried.
Fix this problem by saving the original command residual in struct
scsi_eh_save using scsi_eh_prep_cmnd() and restoring it in
scsi_eh_restore_cmnd(). In addition, to make sure that the request sense
command is executed with a correctly initialized command structure, also
reset the residual to 0 in scsi_eh_prep_cmnd() after saving the original
command value in struct scsi_eh_save.

Various keyboards have macro keys, which are intended to have user
programmable actions / key-sequences bound to them. In some cases these
macro keys are actually programmable in hardware, but more often they
basically are just extra keys and the playback of the key-sequence is done
by software running on the host.
One example of keyboards with macro-keys are various "internet" / "office"
keyboards have a set of so-called "Smart Keys", typically a set of 4 keys
labeled "[A]" - "[D]".
Another example are gaming keyboards, such as the Logitech G15 Gaming
keyboard, which has 18 "G"aming keys labeled "G1" to G18", 3 keys to select
macro presets labeled "M1" - "M3" and a key to start recording a macro
called "MR" note that even though there us a record key everything is
handled in sw on the host.
Besides macro keys the G15 (and other gaming keyboards) also has a buildin
LCD panel where the contents are controlled by the host. There are 5 keys
directly below the LCD intended for controlling a menu shown on the LCD.
The Microsoft SideWinder X6 keyboard is another gaming keyboard example,
this keyboard has 30 "S"idewinder keys and a key to cycle through
macro-presets.
After discussion between various involved userspace people we've come to
the conclusion that since these are all really just extra keys we should
simply treat them as such and give them their own event-codes, see:
https://github.com/libratbag/libratbag/issues/172
This commit adds the following new KEY_ defines for this:
KEY_MACRO1 - KEY_MACRO30. KEY_MACRO_RECORD_START/-STOP,
KEY_MACRO_PRESET_CYCLE, KEY_MACRO_PRESET1 - KEY_MACRO_PRESET3,
KEY_KBD_LCD_MENU1 - KEY_KBD_LCD_MENU5.
The defines leave room for adding some more LCD-menu, preset or macro keys,
the maximum values above are based on the maximum values to support all
currently known internet, office and gaming keyboards.

This renames the very specific audit_log_link_denied() to
audit_log_path_denied() and adds the AUDIT_* type as an argument. This
allows for the creation of the new AUDIT_ANOM_CREAT that can be used to
report the fifo/regular file creation restrictions that were introduced
in commit 30aba6656f61 ("namei: allow restricted O_CREAT of FIFOs and
regular files").

The secure monitor driver is currently a frankenstein driver which is
registered as a platform driver but its functionality goes through a
global struct accessed by the consumer drivers using exported helper
functions.
Try to tidy up the driver moving the firmware struct into the driver
data and make the consumer drivers referencing the secure-monitor using
a new property in the DT.
Currently only the nvmem driver is using this API so we can fix it in
the same commit.

This introduces fwnode_gpiod_get_index() that iterates through common gpio
suffixes when trying to locate a GPIO within a given firmware node.
We also switch devm_fwnode_gpiod_get_index() to call
fwnode_gpiod_get_index() instead of iterating through GPIO suffixes on
its own.

devm_fwnode_get_index_gpiod_from_child() is too long, besides the fwnode
in question does not have to be a child of device node. Let's rename it
to devm_fwnode_gpiod_get_index() and keep the old name for compatibility
for now.
Also let's add a devm_fwnode_gpiod_get() wrapper as majority of the
callers need a single GPIO.

The struct __dsa_skb_cb is supposed to span the entire 48-byte skb
control block, while the struct dsa_skb_cb only the portion of it which
is used by the DSA core (the rest is available as private data to
drivers).
The DSA_SKB_CB and __DSA_SKB_CB helpers are supposed to help retrieve
this pointer based on a skb, but it turns out there is nobody directly
interested in the struct __dsa_skb_cb in the kernel. So remove it.
