though, since we might still have the station. Remove it

Wireless extensions are already disabled if MLO is enabled,
given that we cannot support MLO there with all the hard-
coded assumptions about BSSID etc.
However, the WiFi7 ecosystem is still stabilizing, and some
devices may need MLO disabled while that happens. In that
case, we might end up with a device that supports wext (but
not MLO) in one kernel, and then breaks wext in the future
(by enabling MLO), which is not desirable.
Add a flag to let such drivers/devices disable wext even if
MLO isn't yet enabled.

This patch checks for a bad_inode before doing anything other

Currently, the LBR code assumes that LBR Freeze is supported on all processors
when X86_FEATURE_AMD_LBR_V2 is available i.e. CPUID leaf 0x80000022[EAX]
bit 1 is set. This is incorrect as the availability of the feature is
additionally dependent on CPUID leaf 0x80000022[EAX] bit 2 being set,
which may not be set for all Zen 4 processors.
Define a new feature bit for LBR and PMC freeze and set the freeze enable bit
(FLBRI) in DebugCtl (MSR 0x1d9) conditionally.
It should still be possible to use LBR without freeze for profile-guided
optimization of user programs by using an user-only branch filter during
profiling. When the user-only filter is enabled, branches are no longer
recorded after the transition to CPL 0 upon PMI arrival. When branch
entries are read in the PMI handler, the branch stack does not change.
E.g.
$ perf record -j any,u -e ex_ret_brn_tkn ./workload
Since the feature bit is visible under flags in /proc/cpuinfo, it can be
used to determine the feasibility of use-cases which require LBR Freeze
to be supported by the hardware such as profile-guided optimization of
kernels.

Particularly, the below text from the RISC-V AIA specification defines

interrupts:
"A second option is for the interrupt service routine to write the
APLIC’s source identity number for the interrupt to the domain’s
setipnum register just before exiting. This will cause the interrupt’s

an interrupt, but not if the source is not asserting an interrupt."

syzbot reported an ext4 panic during a page fault where found a
journal handle when it didn't expect to find one. The structure
it tripped over had a value of 'TRAN' in the first entry in the
structure, and that indicates it tripped over a struct xfs_trans
instead of a jbd2 handle.
The reason for this is that the page fault was taken during a
copy-out to a user buffer from an xfs bulkstat operation. XFS uses
an "empty" transaction context for bulkstat to do automated metadata
buffer cleanup, and so the transaction context is valid across the
copyout of the bulkstat info into the user buffer.
We are using empty transaction contexts like this in XFS to reduce
the risk of failing to release objects we reference during the
operation, especially during error handling. Hence we really need to
ensure that we can take page faults from these contexts without
leaving landmines for the code processing the page fault to trip
over.
However, this same behaviour could happen from any other filesystem
that triggers a page fault or any other exception that is handled
on-stack from within a task context that has current->journal_info
set. Having a page fault from some other filesystem bounce into XFS
where we have to run a transaction isn't a bug at all, but the usage
of current->journal_info means that this could result corruption of
the outer task's journal_info structure.
The problem is purely that we now have two different contexts that
now think they own current->journal_info. IOWs, no filesystem can
allow page faults or on-stack exceptions while current->journal_info
is set by the filesystem because the exception processing might use
current->journal_info itself.
If we end up with nested XFS transactions whilst holding an empty
transaction, then it isn't an issue as the outer transaction does
not hold a log reservation. If we ignore the current->journal_info
usage, then the only problem that might occur is a deadlock if the
exception tries to take the same locks the upper context holds.
That, however, is not a problem that setting current->journal_info
would solve, so it's largely an irrelevant concern here.
IOWs, we really only use current->journal_info for a warning check
in xfs_vm_writepages() to ensure we aren't doing writeback from a
transaction context. Writeback might need to do allocation, so it
can need to run transactions itself. Hence it's a debug check to
warn us that we've done something silly, and largely it is not all
that useful.
So let's just remove all the use of current->journal_info in XFS and
get rid of all the potential issues from nested contexts where
current->journal_info might get misused by another filesystem
context.

If a filesystem has a busted stripe alignment configuration on disk
(e.g. because broken RAID firmware told mkfs that swidth was smaller
than sunit), then the filesystem will refuse to mount due to the
stripe validation failing. This failure is triggering during distro
upgrades from old kernels lacking this check to newer kernels with
this check, and currently the only way to fix it is with offline
xfs_db surgery.
This runtime validity checking occurs when we read the superblock
for the first time and causes the mount to fail immediately. This
prevents the rewrite of stripe unit/width via
mount options that occurs later in the mount process. Hence there is
no way to recover this situation without resorting to offline xfs_db
rewrite of the values.
However, we parse the mount options long before we read the
superblock, and we know if the mount has been asked to re-write the
stripe alignment configuration when we are reading the superblock
and verifying it for the first time. Hence we can conditionally
ignore stripe verification failures if the mount options specified
will correct the issue.
We validate that the new stripe unit/width are valid before we
overwrite the superblock values, so we can ignore the invalid config
at verification and fail the mount later if the new values are not
valid. This, at least, gives users the chance of correcting the
issue after a kernel upgrade without having to resort to xfs-db
hacks.

According to the hardware design, the i2c address of audio codec es8316
on Cool Pi CM5 is 0x10.
This fix the read/write error like bellow:

The PCIe PHY requires two regulators and are present on the SoM
directly, while the PCIe connector also exposes 3V3 and 12V power rails
which are available on the baseboard.
Considering that 3/4 regulators are always-on on HW level and that the
last one depends on a regulator from the PMIC that is specified as
always on, this commit should be purely cosmetic and no change in
behavior is expected.
Let's add all regulators for PCIe on RK3399 Puma Haikou.

The PCIE_WAKE# has a diode used as a level-shifter, and is used as an
input pin. While the SoC default is to enable the pull-up, the core
rk3399 pinconf for this pin opted for pull-none. So as to not disturb
the behaviour of other boards which may rely on pull-none instead of
pull-up, set the needed pull-up only for RK3399 Puma.

The Q7_USB_ID has a diode used as a level-shifter, and is used as an
input pin. The SoC default for this pin is a pull-up, which is correct
but the pinconf in the introducing commit missed that, so let's fix this
oversight.

Q7_THRM# pin is connected to a diode on the module which is used
as a level shifter, and the pin have a pull-down enabled by
default. We need to configure it to internal pull-up, other-
wise whenever the pin is configured as INPUT and we try to
control it externally the value will always remain zero.

The MT7531 switch listens on PHY address 0x1f on an MDIO bus. I've got two
findings that support this. There's no bootstrapping option to change the
PHY address of the switch. The Linux driver hardcodes 0x1f as the PHY
address of the switch. So the reg property on the device tree is currently
ignored by the Linux driver.
Therefore, describe the correct PHY address on Banana Pi BPI-R2 Pro that
has this switch.
