[ Upstream commit e599046994 ]
When serial console over USB is enabled, gs_console_connect
queues gs_console_work, where it acquires the spinlock and
queues the usb request, and this request goes to gadget layer.
Now consider a situation where gadget layer prints something
to dmesg, this will eventually call gs_console_write() which
requires cons->lock. And this causes spinlock recursion. Avoid
this by excluding usb_ep_queue from the spinlock.

From the experiments with camera sensors using SGRBG10_1X10/3280x2464 and
SRGGB10_1X10/3280x2464 formats, it becomes clear that on sdm845 and sm8250
VFE outputs the lines padded to a length multiple of 16 bytes. As in the
current driver the value of the bpl_alignment is set to 8 bytes, the frames
captured in formats with the bytes-per-line value being not a multiple of
16 get corrupted.
Set the bpl_alignment of the camss video output device to 16 for sdm845 and
sm8250 to fix that.

[ Upstream commit 6bd6cd29c9 ]
Returning early from stm32_usart_serial_remove() results in a resource
leak as several cleanup functions are not called. The driver core ignores
the return value and there is no possibility to clean up later.
uart_remove_one_port() only returns non-zero if there is some
inconsistency (i.e. stm32_usart_driver.state[port->line].uart_port == NULL).
This should never happen, and even if it does it's a bad idea to exit
early in the remove callback without cleaning up.
This prepares changing the prototype of struct platform_driver::remove to
return void. See commit 5c5a7680e6 ("platform: Provide a remove callback
that returns no value") for further details about this quest.

[ Upstream commit 8635e8df47 ]
This reverts commit cead61a671.
It exported __stack_smash_handler and __guard, while they may not be
defined by anyone.
The code *declares* __stack_smash_handler and __guard. It does not
create weak symbols. If no external library is linked, they are left
undefined, but yet exported.
If a loadable module tries to access non-existing symbols, bad things
(a page fault, NULL pointer dereference, etc.) will happen. So, the
current code is wrong and dangerous.
If the code were written as follows, it would *define* them as weak
symbols so modules would be able to get access to them.
void (*__stack_smash_handler)(void *) __attribute__((weak));
EXPORT_SYMBOL(__stack_smash_handler);
long __guard __attribute__((weak));
EXPORT_SYMBOL(__guard);
In fact, modpost forbids exporting undefined symbols. It shows an error
message if it detects such a mistake.
ERROR: modpost: "..." [...] was exported without definition
Unfortunately, it is checked only when the code is built as modular.
The problem described above has been unnoticed for a long time because
arch/um/os-Linux/user_syms.c is always built-in.
With a planned change in Kbuild, exporting undefined symbols will always
result in a build error instead of a run-time error. It is a good thing,
but we need to fix the breakage in advance.
One fix is to define weak symbols as shown above. An alternative is to
export them conditionally as follows:
#ifdef CONFIG_STACKPROTECTOR
extern void __stack_smash_handler(void *);
EXPORT_SYMBOL(__stack_smash_handler);
external long __guard;
EXPORT_SYMBOL(__guard);
#endif
This is what other architectures do; EXPORT_SYMBOL(__stack_chk_guard)
is guarded by #ifdef CONFIG_STACKPROTECTOR.
However, adding the #ifdef guard is not sensible because UML cannot
enable the stack-protector in the first place! (Please note UML does
not select HAVE_STACKPROTECTOR in Kconfig.)
So, the code is already broken (and unused) in multiple ways.
Just remove.

The shutdown is called on reboot/shutdown of the machine.
At this point the firmware tracing cannot be used anymore but in case of
IPC3 it is using and keeping a DMA channel active (dtrace).
For Tiger Lake platforms we have a quirk in place to fix rare reboot issues
when a DMA was active before rebooting the system.
If the tracing is enabled this quirk will be always used and a print
appears on the kernel log which might be misleading or not even correct.
Release the fw tracing before executing the shutdown to make sure that this

[ Upstream commit 30f90f3c1c ]
[Why]
Hardware implements root clock gating by utilizing the DPP DTO registers
with a special case of DTO enabled, phase = 0, modulo = 1. This
conflicts with our policy to always update the DPPDTO for cases where
it's expected to be disabled.
The pipes unexpectedly enter a higher power state than expected because
of this programming flow.
[How]
Guard the upper layers of HWSS against this hardware quirk with
programming the register with an internal state flag in DCCG.
While technically acting as global state for the DCCG, HWSS shouldn't be
expected to understand the hardware quirk for having DTO disabled
causing more power than DTO enabled with this specific setting.
This also prevents sequencing errors from occuring in the future if
we have to program DPP DTO in multiple locations.

[ Upstream commit 66419036f6 ]
An Interrupt Remapping Table (IRT) stores interrupt remapping configuration
for each device. In a normal operation, the AMD IOMMU caches the table
to optimize subsequent data accesses. This requires the IOMMU driver to
invalidate IRT whenever it updates the table. The invalidation process
includes issuing an INVALIDATE_INTERRUPT_TABLE command following by
a COMPLETION_WAIT command.
However, there are cases in which the IRT is updated at a high rate.
For example, for IOMMU AVIC, the IRTE[IsRun] bit is updated on every
vcpu scheduling (i.e. amd_iommu_update_ga()). On system with large
amount of vcpus and VFIO PCI pass-through devices, the invalidation
process could potentially become a performance bottleneck.
Introducing a new kernel boot option:
amd_iommu=irtcachedis
which disables IRTE caching by setting the IRTCachedis bit in each IOMMU
Control register, and bypass the IRT invalidation process.

[ Upstream commit 7607f12ba7 ]
In the beginning, commit 18eeef46d3 ("HID: i2c-hid: goodix: Tie the
reset line to true state of the regulator") introduced a change to tie
the reset line of the Goodix touchscreen to the state of the regulator
to fix a power leakage issue in suspend.
After some time, the change was deemed unnecessary and was reverted in
commit 557e05fa9f ("HID: i2c-hid: goodix: Stop tying the reset line to
the regulator") due to difficulties in managing regulator notifiers for
designs like Evoker, which provides a second power rail to touchscreen.
However, the revert caused a power regression on another Chromebook
device Steelix in the field, which has a dedicated always-on regulator
for touchscreen and was covered by the workaround in the first commit.
To address both cases, this patch adds the support for the new
"goodix,no-reset-during-suspend" property in the driver:
- When set to true, the driver does not assert the reset GPIO during
power-down.
Instead, the GPIO will be asserted during power-up to ensure the
touchscreen always has a clean start and consistent behavior after
resuming.
This is for designs with a dedicated always-on regulator.
- When set to false or unset, the driver uses the original control flow
and asserts GPIO and disables regulators normally.
This is for the two-regulator and shared-regulator designs.

To address that, we add this property to skip reset during suspend.

[ Upstream commit b407460ee9 ]
It is considered good practice to call cpu_relax() in busy loops, see
Documentation/process/volatile-considered-harmful.rst. This can not
only lower CPU power consumption or yield to a hyperthreaded twin
processor, but also allows an architecture to mitigate hardware issues
(e.g. ARM Erratum 754327 for Cortex-A9 prior to r2p0) in the
architecture-specific cpu_relax() implementation.
In addition, cpu_relax() is also a compiler barrier. It is not
immediately obvious that the @op argument "function" will result in an
actual function call (e.g. in case of inlining).
Where a function call is a C sequence point, this is lost on inlining.
Therefore, with agressive enough optimization it might be possible for
the compiler to hoist the:
(val) = op(args);
"load" out of the loop because it doesn't see the value changing. The
addition of cpu_relax() would inhibit this.
As the iopoll helpers lack calls to cpu_relax(), people are sometimes
reluctant to use them, and may fall back to open-coded polling loops
(including cpu_relax() calls) instead.
Fix this by adding calls to cpu_relax() to the iopoll helpers:
- For the non-atomic case, it is sufficient to call cpu_relax() in
case of a zero sleep-between-reads value, as a call to
usleep_range() is a safe barrier otherwise. However, it doesn't
hurt to add the call regardless, for simplicity, and for similarity
with the atomic case below.
- For the atomic case, cpu_relax() must be called regardless of the
sleep-between-reads value, as there is no guarantee all
architecture-specific implementations of udelay() handle this.

[ Upstream commit 205b3d02d5 ]
Add check to fix the possible array out of bounds violation by
making speed equal to GEN1_CORE_CLK_FREQ when its value is more
than the size of "pcie_gen_freq" array. This array has size of
four but possible speed (CLS) values are from "0 to 0xF". So,
"speed - 1" values are "-1 to 0xE".

This reverts commit 80c6d6804f.
The orignal commit was intended as a workaround to prevent underflow and
flickering when using one normal monitor and the other high refresh rate
monitor (> 120Hz).
This patch is being reverted in favour of a software solution to enable

For smu v13_0_2, if the GPU supports xgmi, refer to
commit f5c7e77970 ("drm/amdgpu: Adjust removal control flow for smu v13_0_2"),
it will run gpu recover in AMDGPU_RESET_FOR_DEVICE_REMOVE mode when removing,
which makes all devices in hive list have hw reset but no resume except the
basic ip blocks, then other ip blocks will not call .hw_fini according to
ip_block.status.hw.
Since psp_free_shared_bufs just includes some software operations, so move
it to psp_sw_fini.

[ Upstream commit 96c7c2f4d5 ]
It already happend a few times that patches slipped through which
implemented access to an entity through a job that was already removed
from the entities queue. Since jobs and entities might have different
lifecycles, this can potentially cause UAF bugs.
In order to make it obvious that a jobs entity pointer shouldn't be
accessed after drm_sched_entity_pop_job() was called successfully, set
the jobs entity pointer to NULL once the job is removed from the entity
queue.
Moreover, debugging a potential NULL pointer dereference is way easier
than potentially corrupted memory through a UAF.

- This is required because DTO programming
requires exact DTBCLK reference freq or it could

[ Upstream commit e58f30246c ]
In commit 7beecaf7d5 ("net: phy: at803x: improve the WOL feature"), it
seems not correct to use a wol_en bit in a 1588 Control Register which is
only available on AR8031/AR8033(share the same phy_id) to determine if WoL
is enabled. Change it back to use AT803X_INTR_ENABLE_WOL for determining
the WoL status which is applicable on all chips supporting wol. Also update
the at803x_set_wol() function to only update the 1588 register on chips
having it. After this change, disabling wol at probe from commit
d7cd5e06c9 ("net: phy: at803x: disable WOL at probe") is no longer
needed. Change it to just disable the WoL bit in 1588 register for
AR8031/AR8033 to be aligned with AT803X_INTR_ENABLE_WOL in probe.
