The "expert" menu was broken (split) such that all entries in it after
KALLSYMS were displayed in the "General setup" area instead of in the
"Expert users" area. Fix this by adding one kconfig dependency.
Yes, the Expert users menu is fragile. Problems like this have happened
several times in the past. I will attempt to isolate the Expert users
menu if there is interest in that.

cpufreq drivers aren't required to provide a sorted frequency table
today, and even the ones which provide a sorted table aren't handled
efficiently by cpufreq core.
This patch adds infrastructure to verify if the freq-table provided by
the drivers is sorted or not, and use efficient helpers if they are
sorted.

This patch adds support for platform initited graceful shutdown as
described in sections 5.6.6(Table-143) and 6.3.5.1 of ACPI 6.1 spec
The OSPM will get a graceful shutdown request via a Notify operator
on \_SB device with a value of 0x81 per section 5.6.6. Following the
shutdown request from platform the OSPM needs to follow the
processing sequence as described in section 6.2.5.1.

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next,
they are:
1) Don't use userspace datatypes in bridge netfilter code, from
Tobin Harding.
2) Iterate only once over the expectation table when removing the
helper module, instead of once per-netns, from Florian Westphal.
3) Extra sanitization in xt_hook_ops_alloc() to return error in case
we ever pass zero hooks, xt_hook_ops_alloc():
4) Handle NFPROTO_INET from the logging core infrastructure, from
Liping Zhang.
5) Autoload loggers when TRACE target is used from rules, this doesn't
change the behaviour in case the user already selected nfnetlink_log
as preferred way to print tracing logs, also from Liping Zhang.
6) Conntrack slabs with SLAB_HWCACHE_ALIGN to allow rearranging fields
by cache lines, increases the size of entries in 11% per entry.
From Florian Westphal.
7) Skip zone comparison if CONFIG_NF_CONNTRACK_ZONES=n, from Florian.
8) Remove useless defensive check in nf_logger_find_get() from Shivani
Bhardwaj.
9) Remove zone extension as place it in the conntrack object, this is
always include in the hashing and we expect more intensive use of
zones since containers are in place. Also from Florian Westphal.
10) Owner match now works from any namespace, from Eric Bierdeman.
11) Make sure we only reply with TCP reset to TCP traffic from
nf_reject_ipv4, patch from Liping Zhang.
12) Introduce --nflog-size to indicate amount of network packet bytes
that are copied to userspace via log message, from Vishwanath Pai.
This obsoletes --nflog-range that has never worked, it was designed
to achieve this but it has never worked.
13) Introduce generic macros for nf_tables object generation masks.
14) Use generation mask in table, chain and set objects in nf_tables.
This allows fixes interferences with ongoing preparation phase of
the commit protocol and object listings going on at the same time.
This update is introduced in three patches, one per object.
15) Check if the object is active in the next generation for element
deactivation in the rbtree implementation, given that deactivation
happens from the commit phase path we have to observe the future
status of the object.
16) Support for deletion of just added elements in the hash set type.
17) Allow to resize hashtable from /proc entry, not only from the
obscure /sys entry that maps to the module parameter, from Florian
Westphal.
18) Get rid of NFT_BASECHAIN_DISABLED, this code is not exercised
anymore since we tear down the ruleset whenever the netdevice
goes away.
19) Support for matching inverted set lookups, from Arturo Borrero.
20) Simplify the iptables_mangle_hook() by removing a superfluous
extra branch.
21) Introduce ether_addr_equal_masked() and use it from the netfilter
codebase, from Joe Perches.
22) Remove references to "Use netfilter MARK value as routing key"
from the Netfilter Kconfig description given that this toggle
doesn't exists already for 10 years, from Moritz Sichert.
23) Introduce generic NF_INVF() and use it from the xtables codebase,
from Joe Perches.
24) Setting logger to NONE via /proc was not working unless explicit
nul-termination was included in the string. This fixes seems to
leave the former behaviour there, so we don't break backward.

This driver parses the reboot commands like "reboot bootloader"
and "reboot recovery" to get a boot mode described in the
device tree , then call the write interfae to store the boot
mode in some place like special register or sram, which can
be read by the bootloader after system reboot, then the bootloader
can take different action according to the mode stored.
This is commonly used on Android based devices, in order to
reboot the device into fastboot or recovery mode.

Speedy join only works when the received packet is either broadcast or an
4addr unicast packet. Thus packets converted from broadcast to unicast via
the gateway handling code have to be converted to 4addr packets to allow
the receiving gateway server to add the sender address as temporary entry
to the translation table.
Not doing it will make the batman-adv gateway server drop the DHCP response
in many situations because it doesn't yet have the TT entry for the
destination of the DHCP response.

to that for parsing semantics, particularly with the workaround.
While at it, remove some dead code - the IEEE80211_STA_DISABLE_40MHZ

wide_bw_chansw_ie pointer is set to NULL if it's set.

Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.
In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.
Supporting beacon report is required for Multi Band Operation (MBO).

MAC address to monitor mode.
that option will be used by VHT MU-MIMO air sniffer to follow a
station according to it's MAC address using VHT MU-MIMO.

The current implementation of handling ADDBA Request while a session
is already active with the peer is wrong - in case the peer is using
the existing session's dialog token this should be treated as update
to the session, which can update the timeout value.
We don't really have a good way of supporting that, so reject, but
implement the required behaviour in the spec of "Even if the updated
ADDBA Request frame is not accepted, the original Block ACK setup
remains active." (802.11-2012 10.5.4)

This reverts commit 7e7c059cb50c7c72d5a393b2c34fc57de1b01b55.
I was wrong about trying to do this, as it breaks the
orthogonality between gpiochips and irqchips.

Since commit dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property
names") when requesting a GPIO from the devicetree gpiolib looks for
properties with both the '-gpio' and the '-gpios' suffix. This was
implemented by first searching for the property with the '-gpios' suffix
and if that yields an error try the '-gpio' suffix. This approach has the
issue that any error returned when looking for the '-gpios' suffix is
silently discarded.
Commit 06fc3b70f1dc ("gpio: of: Fix handling for deferred probe for -gpio
suffix") partially addressed the issue by treating the EPROBE_DEFER error
as a special condition. This fixed the case when the property is specified,
but the GPIO provider is not ready yet. But there are other cases in which
of_get_named_gpiod_flags() returns an error even though the property is
specified, e.g. if the specification is incorrect.
of_find_gpio() should only try to look for the property with the '-gpio'
suffix if no property with the '-gpios' suffix was found. If the property
was not found of_get_named_gpiod_flags() will return -ENOENT, so update the
condition to abort and propagate the error to the caller in all other
cases.
This is important for gpiod_get_optinal() and friends to behave correctly
in case the specifier contains errors. Without this patch they'll return
NULL if the property uses the '-gpios' suffix and the specifier contains
errors, which falsely indicates to the caller that no GPIO was specified.

When registering a GPIO chip, drivers can override the device tree node
associated with the chip by setting the chip's ->of_node field. If set,
this field is supposed to take precedence over the ->parent->of_node
field, but the code doesn't actually do that.
Commit 762c2e46c059 ("gpio: of: remove of_gpiochip_and_xlate() and
struct gg_data") exposes this because it now no longer matches on the
GPIO chip's ->of_node field, but the GPIO device's ->of_node field that
is set using the procedure described above.
