The problem case is as follows:
1. GPU A triggers a gpu ras reset, and GPU A drives
GPU B to also perform a gpu ras reset.
2. After gpu B ras reset started, gpu B queried a DE
data. Since the DE data was queried in the ras reset
thread instead of the page retirement thread, bad
page retirement work would not be triggered. Then
even if all gpu resets are completed, the bad pages
will be cached in RAM until GPU B's bad page retirement
work is triggered again and then saved to eeprom.
This patch can save the bad pages to eeprom in time after gpu
ras reset is completed.
v2:
1. Add the above description to code comments.
2. Reuse existing function.

Why:
If the reg mmMP1_SMN_C2PMSG_90 is being written to during amdgpu driver
load or driver unload, subsequent amdgpu driver load will fail at
smu_hw_init. The default of mmMP1_SMN_C2PMSG_90 register at a clean
environment is 0x1 and if value differs from expected, amdgpu driver
load will fail.
How to fix:
Ignore the initial value in smu response register before the first smu
message is sent,if smc in SMU_FW_INIT state, just proceed further to
send the message. If register holds an unexpected value after smu message
was sent set, smc_state to SMU_FW_HANG state and no further smu messages
will be sent.
v2:
Set SMU_FW_INIT state at the start of smu hw_init/resume.
Check smc_fw_state before sending smu message if in hang state skip
sending message.
Set SMU_FW_HANG only in case unexpected value is detected

In order to use toshiba_dmi_quirks[] together with the standard DMI

Since this entry is missing, an array out-of-bounds access occurs
every time the quirk list is processed.

Most writes to configfs handle an optional newline, but do not require
it. By using the number of bytes written as the limit for scnprintf()
it is guaranteed that the final character in the buffer will be
overwritten.
This is expected if it is a newline but is undesirable when a string is
written "as-is" (as libusbgx does, for example).
Update the store function to strip an optional newline, matching the
behaviour of usb_string_copy().

Adds a misc driver for Marvell CN10K DPI(DMA Engine) device's physical
function which initializes DPI DMA hardware's global configuration and
enables hardware mailbox channels between physical function (PF) and
it's virtual functions (VF). VF device drivers (User space drivers) use
this hw mailbox to communicate any required device configuration on it's
respective VF device. Accordingly, this DPI PF driver provisions the
VF device resources.
At the hardware level, the DPI physical function (PF) acts as a management
interface to setup the VF device resources, VF devices are only provisioned
to handle or control the actual DMA Engine's data transfer capabilities.

The various kthreads thread functions (slot_handler_func, sync_func,
recycle_func) in vchiq_core and vchiq_keepalive_thread_func in
vchiq_arm should be stopped when the module is unloaded.
Previous attempt were made to address this but later reverted [1]
due to VC04 firmware corruption. The issue around
wait_event_interruptible() handling on stopping a kthread has been
handled in the previous commit. Hence, it is now safe to stop kthreads
on module unload, without any firmware corruption.
This also completes the "Fix kernel module support" TODO item, hence
drop it from the list.

wait_event_interruptible() returns if the condition evaluates to true
it receives a signal. However, the current code always assume that the
wait_event_interruptible() returns only when the event is fired.
This should not be the case as wait_event_interruptible() can
return on receiving a signal (with -ERESTARTSYS as return value).
We should consider this and bubble up the return value of
wait_event_interruptible() to exactly know if the wait has failed
and error out. This will also help to properly stop kthreads in the
subsequent patch.
Meanwhile at it, remote_wait_event() is modified to return 0 on success,
and an error code (from wait_event_interruptible()) on failure. The
return value is now checked for remote_wait_event() calls.

The helper calculate_psi_aligned_address() is used to convert an arbitrary
range into a size-aligned one.
The aligned_pages variable is calculated from input start and end, but is
not adjusted when the start pfn is not aligned and the mask is adjusted,
which results in an incorrect number of pages returned.
The number of pages is used by qi_flush_piotlb() to flush caches for the
first-stage translation. With the wrong number of pages, the cache is not
synchronized, leading to inconsistencies in some cases.

Since address bits masked start from bit 12, the max address mask should

A standard implementation of shutdown callback has been implemented
for USB drivers. Since the UAS driver implements a shutdown callback
this patch enables it to use the new standard implementation.

Currently there is no standardized method for USB drivers to handle
shutdown events. This patch simplifies running code on shutdown for USB
devices by adding a shutdown callback to usb_driver.

i2c_device_id::driver_data to 0
These driver don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

The GSBUSCFG0 register bits [31:16] are used to configure the cache type
settings of the descriptor and data write/read transfers (Cacheable,
Bufferable/Posted). When CCI is enabled in the design, DWC3 core GSBUSCFG0
cache bits must be updated to support CCI enabled transfers in USB.
To program GSBUSCFG0 cache bits create a software node property
in AMD-xilinx dwc3 glue driver and pass it to dwc3 core. The core
then reads this property value and configures it in dwc3_core_init()
sequence.

The size of the internal RAM of the DesignWare USB controller changed
between the different Lantiq SoCs. We have the following sizes:
Amazon + Danube: 8 KByte
Amazon SE + arx100: 2 KByte
xrx200 + xrx300: 2.5 KByte
For Danube SoC we do not provide the params and let the driver decide
to use sane defaults, for the Amazon SE and arx100 we use small fifos
and for the xrx200 and xrx300 SCs a little bit bigger periodic fifo.
The auto detection of max_transfer_size and max_packet_count should
work, so remove it.
This patch is included in OpenWrt for many years.

The MIDI2 gadget driver handled the default MIDI protocol version
incorrectly due to the confusion of the protocol version passed via
configfs (either 1 or 2) and UMP protocol bits (0x100 / 0x200).
As a consequence, the default protocol always resulted in MIDI1.
This patch addresses the misunderstanding of the protocol handling.

Adding stripes to an existing raid4/5/6/10 mapped device grows its
capacity though it'll be only made available _after_ the respective
reshape finished as of MD kernel reshape semantics. Such reshaping
involves moving a window forward starting at BOD reading content
from previous lesser stripes and writing them back in the new
layout with more stripes. Once that process finishes at end of
previous data, the grown size may be announced and used. In order
to avoid writing over any existing data in place, out-of-place space
is added to the beginning of each data device by lvm2 before starting
the reshape process. That reshape space wasn't taken into acount for
data device size calculation.
Fixes resulting from above:
- correct event handling conditions in do_table_event() to set
the device's capacity after the stripe adding reshape ended
- subtract mentioned out-of-place space doing data device and
array size calculations
- conditionally set capacity as of superblock in preresume
Testing:
- passes all LVM2 RAID tests including new lvconvert-raid-reshape-size.sh one

Support per-sector NVMe metadata in dm-crypt.
This commit changes dm-crypt, so that it can use NVMe metadata to store
authentication information. We can put dm-crypt directly on the top of
NVMe device, without using dm-integrity.
This commit improves write throughput twice, becase the will be no writes
to the dm-integrity journal.

When mutipath_message is called with an action and a device, it needs to
find the pgpath that matches that device. dm_get_device() is not the
right function for this. dm_get_device() will look for a table_device
matching the requested path in use by either the live or inactive table.
If it doesn't find the device, dm_get_device() will open it and add it
to the table. Means that multipath_message will accept any block device,
add it to the table if not present, and then look through the pgpaths
to see if it finds a match. Afterwards it will remove the device if it
was not previously in the table devices list.
This is the only function that can modify the device list of a table
besides the constructors and destructors, and it can only do this when
it was passed an invalid message. Instead, multipath_message() should
call dm_devt_from_path() to get the device dev_t, and match that against
its pgpaths.
