The resume of thermal zones in thermal_pm_notify() is carried out
sequentially, which may be a problem if __thermal_zone_device_update()
takes a significant time to run for some thermal zones, because some
other thermal zones may need to wait for them to resume then and if
any other PM notifiers are going to be invoked after the thermal one,
they will need to wait for it either.
To address this, make thermal_pm_notify() switch the poll_queue delayed
work over to a one-shot thermal_zone_device_resume() work function that
will restore the original one during the thermal zone resume and queue
up poll_queue without a delay for each thermal zone.

In preparation for a subsequent change, move the initialization of the
poll_queue delayed work from thermal_zone_device_register_with_trips()
to thermal_zone_device_init() which is called by the former.
However, because thermal_zone_device_init() is also called by
thermal_pm_notify(), make the latter call cancel_delayed_work() on
poll_queue before invoking the former, so as to allow the work
item to be re-initialized safely.
Also move thermal_zone_device_check() which needs to be defined
before thermal_zone_device_init(), so the latter can pass it to the
INIT_DELAYED_WORK() macro.

There are 3 synchronization issues with thermal zone suspend-resume
during system-wide transitions:
1. The resume code runs in a PM notifier which is invoked after user
space has been thawed, so it can run concurrently with user space
which can trigger a thermal zone device removal. If that happens,
the thermal zone resume code may use a stale pointer to the next
list element and crash, because it does not hold thermal_list_lock
while walking thermal_tz_list.
2. The thermal zone resume code calls thermal_zone_device_init()
outside the zone lock, so user space or an update triggered by
the platform firmware may see an inconsistent state of a
thermal zone leading to unexpected behavior.
3. Clearing the in_suspend global variable in thermal_pm_notify()
allows __thermal_zone_device_update() to continue for all thermal
zones and it may as well run before the thermal_tz_list walk (or
at any point during the list walk for that matter) and attempt to
operate on a thermal zone that has not been resumed yet. It may
also race destructively with thermal_zone_device_init().
To address these issues, add thermal_list_lock locking to
thermal_pm_notify(), especially arount the thermal_tz_list,
make it call thermal_zone_device_init() back-to-back with
__thermal_zone_device_update() under the zone lock and replace
in_suspend with per-zone bool "suspend" indicators set and unset
under the given zone's lock.

All usages of this struct have been removed from the kernel tree.
The struct is still referenced by scripts/check-sysctl-docs but that
script is broken anyways as it only supports the register_sysctl_paths()

In some cases the result of test were hidden inside the stdout and it
was difficult to identify when a test was skipped and why.
List of changes
1. Capitalize all the words that express a test result : "OK", "SKIPPED"
and "FAIL".
2. Place all test result text at the end of the message. This will
prevent the result from being hidden when stdout is verbose.
3. Any other explanation that comes after the result text will be placed
in a new line.
4. All failures are marked as "FAIL"
5. Pipped the failure to stderr in tests 8, 9, 10.
6. Replaced bogus "FAIL" with "SKIPPED" in test 0007
7. All "..." are prefixed and followed by a space.

Basic test to ensure that empty directories can be registered and that
they in turn can serve as a base dir for other registrations.
Add one test to the sysctl selftest module. It first registers an empty
directory under "empty_add" and then uses that as a base to register
another empty dir.
The sysctl bash script then checks that "empty_add" is present and that
there an empty directory within it.

When registering tables to the sysctl subsystem there is a check to see
if header is a permanently empty directory (used for mounts). This check
evaluates the first element of the ctl_table. This results in an out of
bounds evaluation when registering empty directories.
The function register_sysctl_mount_point now passes a ctl_table of size
1 instead of size 0. It now relies solely on the type to identify
a permanently empty register.
Make sure that the ctl_table has at least one element before testing for
permanent emptiness.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Currently the driver accepts VLAN EtherType steering rules regardless of
the configured mask. And things might fail silently or with confusing error
messages to the user. The VLAN EtherType can only be matched by full
mask. Therefore, add a check for that.
For instance the following rule is invalid, but the driver accepts it and
ignores the user specified mask:

Currently the driver accepts VLAN TCI steering rules regardless of the
configured mask. And things might fail silently or with confusing error
messages to the user.
There are two ways to handle the VLAN TCI mask:
1. Match on the PCP field using a VLAN prio filter
2. Match on complete TCI field using a flex filter
Therefore, add checks and code for that.
For instance the following rule is invalid and will be converted into a
VLAN prio rule which is not correct:
|root@host:~# ethtool -N enp3s0 flow-type ether vlan 0x0001 m 0xf000 \

Stop dividing the phase_offset value received from firmware. This fault
is present since the initial implementation.
The phase_offset value received from firmware is in 0.01ps resolution.
Dpll subsystem is using the value in 0.001ps, raw value is adjusted
before providing it to the user.
The user can observe the value of phase offset with response to
`pin-get` netlink message of dpll subsystem for an active pin:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-get --json '{"id":2}'
Where example of correct response would be:
{'board-label': 'C827_0-RCLKA',
'capabilities': 6,
'clock-id': 4658613174691613800,
'frequency': 1953125,
'id': 2,
'module-name': 'ice',
'parent-device': [{'direction': 'input',
'parent-id': 6,
'phase-offset': -216839550,
'prio': 9,
'state': 'connected'},
{'direction': 'input',
'parent-id': 7,
'phase-offset': -42930,
'prio': 8,
'state': 'connected'}],
'phase-adjust': 0,
'phase-adjust-max': 16723,
'phase-adjust-min': -16723,
'type': 'mux'}
Provided phase-offset value (-42930) shall be divided by the user with
DPLL_PHASE_OFFSET_DIVIDER to get actual value of -42.930 ps.
Before the fix, the response was not correct:
{'board-label': 'C827_0-RCLKA',
'capabilities': 6,
'clock-id': 4658613174691613800,
'frequency': 1953125,

'module-name': 'ice',

{'direction': 'input',

'state': 'connected'}],
'phase-adjust': 0,
'phase-adjust-max': 16723,
'phase-adjust-min': -16723,
'type': 'mux'}
Where phase-offset value (-42), after division
(DPLL_PHASE_OFFSET_DIVIDER) would be: -0.042 ps.

A freezable kernel thread can enter frozen state during freezing by
either calling try_to_freeze() or using wait_event_freezable() and its
variants. So for the following snippet of code in a kernel thread loop:
wait_event_interruptible_timeout();
try_to_freeze();
We can change it to a simple wait_event_freezable_timeout() and then
eliminate a function call.

====================
Add MACsec support for TJA11XX C45 PHYs
This is the MACsec support for TJA11XX PHYs. The MACsec block encrypts
the ethernet frames on the fly and has no buffering. This operation will
grow the frames by 32 bytes. If the frames are sent back to back, the
MACsec block will not have enough room to insert the SecTAG and the ICV
and the frames will be dropped.
To mitigate this, the PHY can parse a specific ethertype with some
padding bytes and replace them with the SecTAG and ICV. These padding
bytes might be dummy or might contain information about TX SC that must
be used to encrypt the frame.
