drm: Switch DRM_DISPLAY_HDMI_HELPER to depends on
Most of our helpers have relied on being selected so far through
Kconfig, but that creates issues when we have multiple layers of helpers
with some depending on others.

Indeed, select doesn't select a dependency's dependencies, and thus
isn't super intuitive. Depends on however doesn't have that limitation,
so we can just switch all the drivers that were selecting
DRM_DISPLAY_HDMI_HELPER to depend on it.

drm: Make drivers depends on DRM_DW_HDMI
DRM_DW_HDMI has a number of dependencies that might not be enabled.
However, drivers were used to selecting it while not enforcing the
DRM_DW_HDMI dependencies.

This could result in Kconfig warnings (and further build breakages) such
as:

  Kconfig warnings: (for reference only)
     WARNING: unmet direct dependencies detected for DRM_DW_HDMI
     Depends on [n]: HAS_IOMEM [=y] && DRM [=m] && DRM_BRIDGE [=y] && DRM_DISPLAY_HELPER [=n]

drm/display: Make all helpers visible and switch to depends on
All the helpers Kconfig symbols so far have relied on drivers selecting
them, and that's what most drivers did.

However, this creates an issue nowadays when helpers depend on each
other, and select doesn't transitively select a dependency dependencies.

Depends on doesn't have that limitation though, so let's convert those
symbols to be dependable and use depends on between them too.

On reworking and splitting the at803x driver, in splitting function of
at803x PHYs it was added a NULL dereference bug where priv is referenced
before it's actually allocated and then is tried to write to for the
is_1000basex and is_fiber variables in the case of at8031, writing on
the wrong address.

Fix this by correctly setting priv local variable only after
at803x_probe is called and actually allocates priv in the phydev struct.

Patch #2 reject table flag update interference with netdev basechain
	 hook updates, this can leave hooks in inconsistent

Patch #3 do not unregister netdev basechain hooks if table is dormant.
	 Otherwise, splat with double unregistration is possible.

30f0ced997 dmaengine: tegra186: Fix residual calculation
The existing residual calculation returns an incorrect value when
bytes_xfer == bytes_req. This scenario occurs particularly with drivers
like UART where DMA is scheduled for maximum number of bytes and is
terminated when the bytes inflow stops. At higher baud rates, it could
request the tx_status while there is no bytes left to transfer. This will
lead to incorrect residual being set. Hence return residual as '0' when
bytes transferred equals to the bytes requested.

When building with 'make W=1', clang notices that the computed register
values are never actually written back but instead the wrong variable
is set:

c404f55c26 iommu: Validate the PASID in iommu_attach_device_pasid()
The SVA code checks that the PASID is valid for the device when assigning
the PASID to the MM, but the normal PAGING related path does not check it.

Devices that don't support PASID or PASID values too large for the device
should not invoke the driver callback. The drivers should rely on the
core code for this enforcement.

15fba562f7 netfilter: arptables: Select NETFILTER_FAMILY_ARP when building arp_tables.c
syzkaller started to report a warning below [0] after consuming the
commit 4654467dc7 ("netfilter: arptables: allow xtables-nft only
builds").

The change accidentally removed the dependency on NETFILTER_FAMILY_ARP
from IP_NF_ARPTABLES.

If NF_TABLES_ARP is not enabled on Kconfig, NETFILTER_FAMILY_ARP will
be removed and some code necessary for arptables will not be compiled.

  $ grep -E "(NETFILTER_FAMILY_ARP|IP_NF_ARPTABLES|NF_TABLES_ARP)" .config
  CONFIG_NETFILTER_FAMILY_ARP=y
  # CONFIG_NF_TABLES_ARP is not set
  CONFIG_IP_NF_ARPTABLES=y

  $ make olddefconfig

  $ grep -E "(NETFILTER_FAMILY_ARP|IP_NF_ARPTABLES|NF_TABLES_ARP)" .config
  # CONFIG_NF_TABLES_ARP is not set
  CONFIG_IP_NF_ARPTABLES=y

So, when nf_register_net_hooks() is called for arptables, it will
trigger the splat below.

Now IP_NF_ARPTABLES is only enabled by IP_NF_ARPFILTER, so let's
restore the dependency on NETFILTER_FAMILY_ARP in IP_NF_ARPFILTER.

1e1fb6f00f netfilter: nf_tables: reject table flag and netdev basechain updates
netdev basechain updates are stored in the transaction object hook list.
When setting on the table dormant flag, it iterates over the existing
hooks in the basechain. Thus, skipping the hooks that are being
added/deleted in this transaction, which leaves hook registration in
inconsistent state.

Reject table flag updates in combination with netdev basechain updates
in the same batch:

- Update table flags and add/delete basechain: Check from basechain update
  path if there are pending flag updates for this table.
- add/delete basechain and update table flags: Iterate over the transaction
  list to search for basechain updates from the table update path.

In both cases, the batch is rejected. Based on suggestion from Florian Westphal.

As mentioned in commit 397586506c ("modpost: Add '.ltext' and
'.ltext.*' to TEXT_SECTIONS"), modpost can result in a segmentation
fault due to a NULL pointer dereference in default_mismatch_handler().

find_tosym() can return the original symbol pointer instead of NULL
if a better one is not found.

This fixes the reported segmentation fault.

7e3465f63a kconfig: do not reparent the menu inside a choice block
The boolean 'choice' is used to list exclusively selected config
options.

You must not add a dependency between choice members, because such a
dependency would create an invisible entry.

In the following test case, it is impossible to choose 'C'.

[Test Case 1]

  choice
          prompt "Choose one, but how to choose C?"

  config A
          bool "A"

  config B
          bool "B"

  config C
          bool "C"
          depends on A

  endchoice

Hence, Kconfig shows the following error message:

  Kconfig:1:error: recursive dependency detected!
  Kconfig:1:      choice <choice> contains symbol C
  Kconfig:10:     symbol C is part of choice A
  Kconfig:4:      symbol A is part of choice <choice>
  For a resolution refer to Documentation/kbuild/kconfig-language.rst
  subsection "Kconfig recursive dependency limitations"

However, Kconfig does not report anything for the following similar code:

[Test Case 2]

  choice
         prompt "Choose one, but how to choose B?"

  config A
          bool "A"

  config B
          bool "B"
          depends on A

  config C
          bool "C"

  endchoice

This is because menu_finalize() reparents the menu tree when an entry
depends on the preceding one.

With reparenting, the menu tree:

  choice
   |- A
   |- B
   \- C

... will be transformed into the following structure:

  choice
   |- A
   |  \- B
   \- C

Consequently, Kconfig considers only 'A' and 'C' as choice members.
This behavior is awkward. The second test case should be an error too.

This commit stops reparenting inside a choice.

a1aa5390cc of: module: prevent NULL pointer dereference in vsnprintf()
In of_modalias(), we can get passed the str and len parameters which would
cause a kernel oops in vsnprintf() since it only allows passing a NULL ptr
when the length is also 0. Also, we need to filter out the negative values
of the len parameter as these will result in a really huge buffer since
snprintf() takes size_t parameter while ours is ssize_t...

68fac8ab0f drm/xe/guc: Introduce GuC context ID Manager
While we are already managing GuC IDs directly in GuC submission
code, using bitmap() for MLRC and ida() for SLRC, this code can't
be easily extended to meet additional requirements for SR-IOV use
cases, like limited number of IDs available on VFs, or ID range
reservation for provisioning VFs by the PF.

Add a separate component for managing GuC IDs, that will replace
existing ID management. Start with bitmap() based implementation
that could be optimized later based on perf data.
