The 'motherboard-bus' node in Arm Ltd boards fails schema checks as
'simple-bus' child nodes must have a unit-address. The 'ranges' handling is
also wrong (or at least strange) as the mapping of SMC chip selects should
be in the 'arm,vexpress,v2m-p1' node rather than a generic 'simple-bus'
node. Either there's 1 too many levels of 'simple-bus' nodes or 'ranges'
should be moved down a level. The latter change is more simple, so let's do
that. As the 'ranges' value doesn't vary for a given motherboard instance,
we can move 'ranges' into the motherboard dtsi files.

Nicolas Dichtel says:
====================
This feature has just been merged after the last release, thus it's still
time to fix the uapi.
As stated in the thread, the uapi is based on some magic values (from the
userland POV).
Here is a proposal to simplify this uapi and make it clear how to use it.
The other problem was the notification: changing the default policy may
radically change the packets flows.
v2 -> v3: rebase on top of ipsec tree
v1 -> v2: fix warnings reported by the kernel test robot

pmic_gpio_child_to_parent_hwirq() and
gpiochip_populate_parent_fwspec_fourcell() translate a pinctrl-
spmi-gpio irqspec to an SPMI controller irqspec. When they do
this, they use a fixed SPMI slave ID of 0 and a fixed GPIO
peripheral offset of 0xC0 (corresponding to SPMI address 0xC000).
This translation results in an incorrect irqspec for secondary
PMICs that don't have a slave ID of 0 as well as for PMIC chips
which have GPIO peripherals located at a base address other than
0xC000.
Correct this issue by passing the slave ID of the pinctrl-spmi-
gpio device's parent in the SPMI controller irqspec and by
calculating the peripheral ID base from the device tree 'reg'
property of the pinctrl-spmi-gpio device.

from sysfs
Fan speed minimum can be enforced from sysfs. For example, setting
current fan speed to 20 is used to enforce fan speed to be at 100%
speed, 19 - to be not below 90% speed, etcetera. This feature provides
ability to limit fan speed according to some system wise
considerations, like absence of some replaceable units or high system
ambient temperature.
Request for changing fan minimum speed is configuration request and can
be set only through 'sysfs' write procedure. In this situation value of
argument 'state' is above nominal fan speed maximum.
Return non-zero code in this case to avoid
thermal_cooling_device_stats_update() call, because in this case
statistics update violates thermal statistics table range.
The issues is observed in case kernel is configured with option
CONFIG_THERMAL_STATISTICS.

tx timeout and slot time are currently specified in units of HZ. On
Alpha, HZ is defined as 1024. When building alpha:allmodconfig, this
results in the following error message.
drivers/net/hamradio/6pack.c: In function 'sixpack_open':
drivers/net/hamradio/6pack.c:71:41: error:
unsigned conversion from 'int' to 'unsigned char'
changes value from '256' to '0'
In the 6PACK protocol, tx timeout is specified in units of 10 ms and
transmitted over the wire:
https://www.linux-ax25.org/wiki/6PACK
Defining a value dependent on HZ doesn't really make sense, and
presumably comes from the (very historical) situation where HZ was
originally 100.
Note that the SIXP_SLOTTIME use explicitly is about 10ms granularity:
mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100);
and the SIXP_TXDELAY walue is sent as a byte over the wire.

This driver isn't enabled most places because of the ISA config
dependency, but alpha still has it. And I think the 'Jensen' actually
did have an ISA slot.
However, it doesn't build cleanly, because the "Vortex bus master" code
just casts the skb->data pointer to 'int':
outl((int) (skb->data), ioaddr + Wn7_MasterAddr);
which is all kinds of broken. Even on a good old traditional PC/AT it
would be broken because the high bits will be random kernel address
bits, but presumably the hardware ignores those bits. I mean, it's ISA.
We're talking 16MB dma limits. The "good old days".
Make the build happy with this kind of craziness by using the proper
isa_virt_to_bus() handling that the full bus master code uses anyway
(the Vortex bus mastering is a limited special case).
Who knows, this might even work.

__stack_chk_guard is setup once while init stage and never changed
after that.
Although the modification of this variable at runtime will usually
cause the kernel to crash (so does the attacker), it should be marked
as __ro_after_init, and it should not affect performance if it is
placed in the ro_after_init section.

When we need a buffer for SVE register state we call sve_alloc() to make
sure that one is there. In order to avoid repeated allocations and frees
we keep the buffer around unless we change vector length and just memset()
it to ensure a clean register state. The function that deals with this
takes the task to operate on as an argument, however in the case where we
do a memset() we initialise using the SVE state size for the current task
rather than the task passed as an argument.
This is only an issue in the case where we are setting the register state
for a task via ptrace and the task being configured has a different vector
length to the task tracing it. In the case where the buffer is larger in
the traced process we will leak old state from the traced process to
itself, in the case where the buffer is smaller in the traced process we
will overflow the buffer and corrupt memory.

[Why]
The "base_addr_is_mc_addr" field was added for dcn3.1 support but
pa_config was never updated to set it to false.
Uninitialized memory causes it to be set to true which results in
address mistranslation and white screen.
[How]
Use memset to ensure all fields are initialized to 0 by default.

which indicates in which direction the panel has been mounted.

Current RUNPM mechanism relies on PMFW to master the timing for BACO
in/exit. And that needs cooperation from sound driver for dstate
change notification for function 1(audio). Otherwise(on sound driver
missing), BACO cannot be kicked in correctly and hang will be observed
on RUNPM exit.
By switching back to legacy message way on sound driver missing,
we are able to fix the runpm hang observed for the scenario below:
amdgpu driver loaded -> runpm suspend kicked -> sound driver loaded
