cb3db5f6a5 usb: dwc3: gadget: fix isoc in transfer issue
When I test the uvc gadget function, I find that the uvc
gadget can only transfer the first frame image and then
stop unexpectedly.

Without this patch, the isochronous endpoints doesn't wait
for a XferNotReady event to start the next frame image, and
fail to transfer data. In this case, we will get an endpoint
event DWC3_DEPEVT_XFERINPROGRESS and the event status is
DEPEVT_STATUS_MISSED_ISOC, and the original code try to
issue an EndTransfer command if the started_list is empty.
However, the started_list is never empty, so it doesn't issue
an EndTransfer command and not XferNotReady event happens.

To fix this problem, this patch firstly checks if the event
status is DEPEVT_STATUS_MISSED_ISOC and then unmap the isoc
request and move the request to the pending list. Then it
issue an EndTransfer command if the started_list is empty.
After the EndTransfer is completed, we will get a XferNotReady
event and it can start the isoc requests again.

504eef8f08 UPSTREAM: usb: dwc3: gadget: Remove END_TRANSFER delay
We had a 100us delay to synchronize the END_TRANSFER command completion
before giving back requests to the function drivers. Now, the controller
driver can handle cancelled TRBs with the requests' cancelled_list and
it can also wait until the END_TRANSFER completion before starting new
transfers. Synchronization can simply base on the controller's command
completion interrupt. The 100us delay is no longer needed. Remove this
arbitrary delay.

77bd086802 UPSTREAM: usb: dwc3: gadget: Delay starting transfer
If the END_TRANSFER command hasn't completed yet, then don't send the
START_TRANSFER command. The controller may not be able to start if
that's the case. Some controller revisions depend on this. See
commit 76a638f8ac ("usb: dwc3: gadget: wait for End Transfer to
complete"). Let's only send START_TRANSFER command after the
END_TRANSFER command had completed.

118a59a38b UPSTREAM: usb: dwc3: gadget: Check END_TRANSFER completion
While the END_TRANSFER command is sent but not completed, any request
dequeue during this time will cause the driver to issue the END_TRANSFER
command. The driver needs to submit the command only once to stop the
controller from processing further. The controller may take more time to
process the same command multiple times unnecessarily. Let's add a flag
DWC3_EP_END_TRANSFER_PENDING to check for this condition.

Normally the END_TRANSFER command completion handler will clear the
DWC3_EP_TRANSFER_STARTED flag. However, if the command was sent without
interrupt on completion, then the flag will not be cleared. Make sure to
clear the flag in this case.

9925aa5542 UPSTREAM: driver core: Probe devices asynchronously instead of the driver
Probe devices asynchronously instead of the driver. This results in us
seeing the same behavior if the device is registered before the driver or
after. This way we can avoid serializing the initialization should the
driver not be loaded until after the devices have already been added.

The motivation behind this is that if we have a set of devices that
take a significant amount of time to load we can greatly reduce the time to
load by processing them in parallel instead of one at a time. In addition,
each device can exist on a different node so placing a single thread on one
CPU to initialize all of the devices for a given driver can result in poor
performance on a system with multiple nodes.

This approach can reduce the time needed to scan SCSI LUNs significantly.
The only way to realize that speedup is by enabling more concurrency which
is what is achieved with this patch.

To achieve this it was necessary to add a new member "async_driver" to the
device_private structure to store the driver pointer while we wait on the
deferred probe call.

c4e800504f UPSTREAM: device core: Consolidate locking and unlocking of parent and device
Try to consolidate all of the locking and unlocking of both the parent and
device when attaching or removing a driver from a given device.

To do that I first consolidated the lock pattern into two functions
__device_driver_lock and __device_driver_unlock. After doing that I then
created functions specific to attaching and detaching the driver while
acquiring these locks. By doing this I was able to reduce the number of
spots where we touch need_parent_lock from 12 down to 4.

This patch should produce no functional changes, it is meant to be a code
clean-up/consolidation only.

d8538da00e UPSTREAM: async: Add cmdline option to specify drivers to be async probed
Asynchronous driver probing can help much on kernel fastboot, and
this option can provide a flexible way to optimize and quickly verify
async driver probe.

Also it will help in below cases:
* Some driver actually covers several families of HWs, some of which
  could use async probing while others don't. So we can't simply
  turn on the PROBE_PREFER_ASYNCHRONOUS flag in driver, but use this
  cmdline option, like igb driver async patch discussed at
  https://www.spinics.net/lists/netdev/msg545986.html

* For SOC (System on Chip) with multiple spi or i2c controllers, most
  of the slave spi/i2c devices will be assigned with fixed controller
  number, while async probing may make those controllers get different
  index for each boot, which prevents those controller drivers to be
  async probed. For platforms not using these spi/i2c slave devices,
  they can use this cmdline option to benefit from the async probing.

f2534b7494 phy/rockchip: Add support for INNOSILICON LVDS/TTL PHY
Innosilicon LVDS/TTL PHY implements LVDS TIA/EIA protocol.
Normally, Innosilicon LVDS/TTL PHY contains four 7-bit
parallel-load serial-out shift registers, a 7X clock PLL,
and five Low-Voltage Differential Signaling (LVDS) line drivers
in a single integrated circuit. These functions allow 28 bits
of single-ended LVTTL data to be synchronously transmitted over
five balanced-pair conductors for receipt by a compatible receiver.

In addition, Innosilicon LVDS/TTL PHY could extend from 4 lanes
to N lanes (N is required by the customer). Therefore, the TTL
lines extend respectively.

8562759c8f batman-adv: Avoid free/alloc race when handling OGM2 buffer
commit a8d23cbbf6 upstream.

A B.A.T.M.A.N. V virtual interface has an OGM2 packet buffer which is
initialized using data from the netdevice notifier and other rtnetlink
related hooks. It is sent regularly via various slave interfaces of the
batadv virtual interface and in this process also modified (realloced) to
integrate additional state information via TVLV containers.

It must be avoided that the worker item is executed without a common lock
with the netdevice notifier/rtnetlink helpers. Otherwise it can either
happen that half modified data is sent out or the functions modifying the
OGM2 buffer try to access already freed memory regions.

b5b9c644cf ipv6: restrict IPV6_ADDRFORM operation
commit b6f6118901 upstream.

IPV6_ADDRFORM is able to transform IPv6 socket to IPv4 one.
While this operation sounds illogical, we have to support it.

One of the things it does for TCP socket is to switch sk->sk_prot
to tcp_prot.

We now have other layers playing with sk->sk_prot, so we should make
sure to not interfere with them.

This patch makes sure sk_prot is the default pointer for TCP IPv6 socket.

7967fef2c6 iommu/vt-d: Ignore devices with out-of-spec domain number
commit da72a379b2 upstream.

VMD subdevices are created with a PCI domain ID of 0x10000 or
higher.

These subdevices are also handled like all other PCI devices by
dmar_pci_bus_notifier().

However, when dmar_alloc_pci_notify_info() take records of such devices,
it will truncate the domain ID to a u16 value (in info->seg).
The device at (e.g.) 10000:00:02.0 is then treated by the DMAR code as if
it is 0000:00:02.0.

In the unlucky event that a real device also exists at 0000:00:02.0 and
also has a device-specific entry in the DMAR table,
dmar_insert_dev_scope() will crash on:
   BUG_ON(i >= devices_cnt);

That's basically a sanity check that only one PCI device matches a
single DMAR entry; in this case we seem to have two matching devices.

Fix this by ignoring devices that have a domain number higher than
what can be looked up in the DMAR table.

This problem was carefully diagnosed by Jian-Hong Pan.

commit f649bd9dd5 upstream.

Since commit 3b2323c2c1 ("perf bench futex: Use cpumaps") the default
number of threads the benchmark uses got changed from number of online
CPUs to zero:

  $ perf bench futex wake
  # Running 'futex/wake' benchmark:

  [...]
  [Run 10]: Wokeup 0 of 0 threads in 0.0000 ms
  Wokeup 0 of 0 threads in 0.0004 ms (+-40.82%)

Restore the old behavior by grabbing the number of online CPUs via
cpu->nr:

  $ perf bench futex wake

70f5b36852 i2c: gpio: suppress error on probe defer
commit 3747cd2efe upstream.

If a GPIO we are trying to use is not available and we are deferring
the probe, don't output an error message.
This seems to have been the intent of commit 05c7477885
("i2c: gpio: Add support for named gpios in DT") but the error was
still output due to not checking the updated 'retdesc'.

cce0478d6a drm/i915/gvt: Fix unnecessary schedule timer when no vGPU exits
commit 04d6067f1f upstream.

From commit f25a49ab8a ("drm/i915/gvt: Use vgpu_lock to protect per
vgpu access") the vgpu idr destroy is moved later than vgpu resource
destroy, then it would fail to stop timer for schedule policy clean
which to check vgpu idr for any left vGPU. So this trys to destroy
vgpu idr earlier.
