Do not follow a NULL pointer if the tty_port_client_operations does not
implement the ->lookahead_buf() callback, which is the case with
serdev's ttyport.

The setting of RS485 RTS polarity is inverse in the current driver.
When the property of 'rs485-rts-active-low' is enabled in the dts node,
the RTS signal should be LOW during sending. Otherwise, if there is no
such a property, the RTS should be HIGH during sending.

When changing the console font with ioctl(KDFONTOP) the new font size
can be bigger than the previous font. A previous selection may thus now
be outside of the new screen size and thus trigger out-of-bounds
accesses to graphics memory if the selection is removed in
vc_do_resize().
Prevent such out-of-memory accesses by dropping the selection before the
various con_font_set() console handlers are called.

After commit f2d3b9a46e0e ("ARM: 9220/1: amba: Remove deferred device
addition"), it became possible for amba_read_periphid() to be invoked
concurrently from two threads for a particular AMBA device.
Consider the case where a thread (T0) is registering an AMBA driver, and
searching for all of the devices it can match with on the AMBA bus.
Suppose that another thread (T1) is executing the deferred probe work,
and is searching through all of the AMBA drivers on the bus for a driver
that matches a particular AMBA device. Assume that both threads begin
operating on the same AMBA device and the device's peripheral ID is
still unknown.
In this scenario, the amba_match() function will be invoked for the
same AMBA device by both threads, which means amba_read_periphid()
can also be invoked by both threads, and both threads will be able
to manipulate the AMBA device's pclk pointer without any synchronization.
It's possible that one thread will initialize the pclk pointer, then the
other thread will re-initialize it, overwriting the previous value, and
both will race to free the same pclk, resulting in a use-after-free for
whichever thread frees the pclk last.
Add a lock per AMBA device to synchronize the handling with detecting the
peripheral ID to avoid the use-after-free scenario.
The following KFENCE bug report helped detect this problem:

With 'unevaluatedProperties' support implemented, there's a number of
warnings when running dtbs_check:
arch/arm64/boot/dts/renesas/r9a07g043u11-smarc.dtb: i2c@10058000: Unevaluated properties are not allowed ('resets' was unexpected)
From schema: Documentation/devicetree/bindings/i2c/renesas,riic.yaml
The main problem is that bindings schema marks resets as a required
property for RZ/G2L (and alike) SoC's but resets property is not part
of schema. So to fix this just add a resets property with maxItems
set to 1.

The bt number of qpc_timer of HIP09 increases compared with that of HIP08.
Therefore, qpc_timer_bt_num and num_qpc_timer do not match. As a result,
the driver may fail to allocate qpc_timer. So the driver needs to uniquely
uses qpc_timer_bt_num to represent the bt number of qpc_timer.

Reset support for SATA PHY is somehow broken and after calling it, kernel
is not able to detect and initialize SATA disk Samsung SSD 850 EMT0 [1].
Reset support was introduced in commit 934337080c6c ("phy: marvell:
phy-mvebu-a3700-comphy: Add native kernel implementation") as part of
complete rewrite of this driver. v1 patch series of that commit [2] did
not contain reset support and was tested that is working fine with
Ethernet, SATA and USB PHYs without issues too.
So for now remove broken reset support and change implementation of
power_off callback to power off all functions on specified lane (and not
only selected function) because during startup kernel does not know which
function was selected and configured by bootloader. Same logic was used
also in v1 patch series of that commit.
This change fixes issues with initialization of SATA disk Samsung SSD 850
and disk is working again, like before mentioned commit.
Once problem with PHY reset callback is solved its functionality could be
re-introduced. But for now it is unknown why it does not work.

The driver does not check if the cooling state passed to
gpio_fan_set_cur_state() exceeds the maximum cooling state as
stored in fan_data->num_speeds. Since the cooling state is later
used as an array index in set_fan_speed(), an array out of bounds
access can occur.
This can be exploited by setting the state of the thermal cooling device
to arbitrary values, causing for example a kernel oops when unavailable
memory is accessed this way.

There are two definitions of the is_signed_type() macro: one in
<linux/overflow.h> and a second definition in <linux/trace_events.h>.
As suggested by Linus, move the definition of the is_signed_type() macro
into the <linux/compiler.h> header file. Change the definition of the
is_signed_type() macro to make sure that it does not trigger any sparse
warnings with future versions of sparse for bitwise types.

The stuff programmed into the wm/ddb registers of planes
on disabled pipes doesn't matter. So during readout just
leave our software state tracking for those zeroed.
This should avoid us trying too hard to clean up after
whatever mess the VBIOS/GOP left in there. The actual
hardware state will get cleaned up if/when we enable
the pipe anyway.

Commit 20f85ef89d94 ("drm/i915/backlight: use unique backlight device
names") added support for multiple backlight devices on dual panel
systems, but did so with error handling on -EEXIST from
backlight_device_register(). Unfortunately, that triggered a warning in
dmesg all the way down from sysfs_add_file_mode_ns() and
sysfs_warn_dup().
Instead of optimistically always attempting to register with the default
name ("intel_backlight", which we have to retain for backward
compatibility), check if a backlight device with the name exists first,
and, if so, use the card and connector based name.

If the GuC CTs are full and we need to stall the request submission
while waiting for space, we save the stalled request and where the stall
occurred; when the CTs have space again we pick up the request submission
from where we left off.
If a full GT reset occurs, the state of all contexts is cleared and all
non-guilty requests are unsubmitted, therefore we need to restart the
stalled request submission from scratch. To make sure that we do so,
clear the saved request after a reset.
Fixes note: the patch that introduced the bug is in 5.15, but no
officially supported platform had GuC submission enabled by default
in that kernel, so the backport to that particular version (and only
that one) can potentially be skipped.

Crucible + recent Mesa seems to sometimes hit:
GEM_BUG_ON(num_ccs_blks > NUM_CCS_BLKS_PER_XFER)
And it looks like we can also trigger this with gem_lmem_swapping, if we
modify the test to use slightly larger object sizes.
Looking closer it looks like we have the following issues in
migrate_copy():
- We are using plain integer in various places, which we can easily
overflow with a large object.
- We pass the entire object size (when the src is lmem) into
emit_pte() and then try to copy it, which doesn't work, since we
only have a few fixed sized windows in which to map the pages and
perform the copy. With an object > 8M we therefore aren't properly
copying the pages. And then with an object > 64M we trigger the
GEM_BUG_ON(num_ccs_blks > NUM_CCS_BLKS_PER_XFER).
So it looks like our copy handling for any object > 8M (which is our
CHUNK_SZ) is currently broken on DG2.

====================
net: u64_stats fixups for 32bit.
while looking at the u64-stats patch
https://lore.kernel.org/all/20220817162703.728679-10-bigeasy@linutronix.de
I noticed that u64_stats_fetch_begin() is used. That suspicious thing
about it is that network processing, including stats update, is
performed in NAPI and so I would expect to see
u64_stats_fetch_begin_irq() in order to avoid updates from NAPI during
the read. This is only needed on 32bit-UP where the seqcount is not
used. This is address in 2/2. The remaining user take some kind of
precaution and may use u64_stats_fetch_begin().
I updated the previously mentioned patch to get rid of
u64_stats_fetch_begin_irq(). If this is not considered stable patch
worthy then it can be ignored and considred fixed by the other series
which removes the special 32bit cases.
The xrs700x driver reads and writes the counter from preemptible context
so the only missing piece here is at least disable preemption on the
writer side to avoid preemption while the writer is in progress. The
possible reader would spin then until the writer completes its write
critical section which is considered bad. This is addressed in 1/2 by
using u64_stats_update_begin_irqsave() and so disable interrupts during
the write critical section.
The other closet resemblance I found is mdio_bus.c::mdiobus_stats_acct()
where preemtion is disabled unconditionally. This is something I want to
avoid since it also affects 64bit.

On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the
reader is in preemptible context and the writer side
(u64_stats_update_begin*()) runs in an interrupt context (IRQ or
softirq) then the writer can update the stats during the read operation.
This update remains undetected.
Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP
are not interrupted by a writer. 32bit-SMP remains unaffected by this
change.

xrs700x_read_port_counters() updates the stats from a worker using the
u64_stats_update_begin() version. This is okay on 32-UP since on the
reader side preemption is disabled.
On 32bit-SMP the writer can be preempted by the reader at which point
the reader will spin on the seqcount until writer continues and
completes the update.
Assigning the mib_mutex mutex to the underlying seqcount would ensure
proper synchronisation. The API for that on the u64_stats_init() side
isn't available. Since it is the only user, just use disable interrupts
during the update.
Use u64_stats_update_begin_irqsave() on the writer side to ensure an
uninterrupted update.

We have a cross dependency between KVM and VFIO when using
s390 vfio_pci_zdev extensions for PCI passthrough
To be able to keep both subsystem modular we add a registering
hook inside the S390 core code.
This fixes a build problem when VFIO is built-in and KVM is built
as a module.

The sequence of sections is a bit confusing here:
* we list the mux locking scheme for existing drivers before introducing
what mux locking schemes are
* we list the caveats for each locking scheme (which are tricky) before
the example of the simple use case
Restructure it entirely with the following logic:
* Intro ("I2C muxes and complex topologies")
* Locking
- mux-locked
- example
- caveats
- parent-locked
- example
- caveats
* Complex examples
* Mux type of existing device drivers
While there, also apply some other improvements:
* convert the caveat list from a table (with only one column carrying
content) to a bullet list.
* add a small introductory text to bridge the gap from listing the use
cases to telling about the hardware components to handle them and then
the device drivers that implement those.
* make empty lines usage more uniform

It would be easy to just convert it to plain text, but rather remove it and
add an introductory text before the list that conveys the same meaning but
with a better reading flow.

Upon reception, a packet must be categorized, either it's destination is
the host, or it is another host. A packet with no destination addressing
fields may be valid in two situations:
- the packet has no source field: only ACKs are built like that, we
consider the host as the destination.
- the packet has a valid source field: it is directed to the PAN
coordinator, as for know we don't have this information we consider we
are not the PAN coordinator.
There was likely a copy/paste error made during a previous cleanup
because the if clause is now containing exactly the same condition as in
the switch case, which can never be true. In the past the destination
address was used in the switch and the source address was used in the
if, which matches what the spec says.

i.MX fixes for 6.0:
- Remove superfluous interrupt-names from imx8mq-tqma8mq RTC device to
silence dtbs_check warning.
- A few Verdin board fixes on CAN clock frequency, mcp251xfd interrupt,
atmel_mxt_ts reset polarity and USB PHY.
- Remove duplicated node and fix spi-flash compatible for
imx6qdl-kontron-samx6i.
- A couple of i.MX8M Plus DHCOM fixes from Marek Vasut on ECSPI1 pinmux
and I2C5 GPIO assignment.
- A couple of Venice fixes on SAI2 pin settings and phy-mode.
- Drop in-band autoneg for 2500base-x phy-mode on ls1028a-qds-65bb
board.
- Revert the power device name setting change from imx8m-blk-ctrl
driver, as it causes issue for sysfs cleanup path.
- Fix gpcv2 driver to assert reset before ungating clock.

Fix the order of source and destination addresses when resolving the
route between server and client to validate use of correct net device.
The reverse order we had so far didn't actually validate the net device
as the server would try to resolve the route to itself, thus always
getting the server's net device.
The issue was discovered when running cm applications on a single host
between 2 interfaces with same subnet and source based routing rules.
When resolving the reverse route the source based route rules were
ignored.

to hang immediately as soon as it tries to print something.
