Rebinding might allocate page-table bos, causing evictions.
To support blocking locking during these evictions,
perform the rebinding in the drm_exec locking loop.
Also Reserve fence slots where actually needed rather than trying to
predict how many fence slots will be needed over a complete
wound-wait transaction.

add a huge number of TLB invalidation fences to wait for so

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.

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.

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.

Commit b4d3ddd2df ("scsi: libsas: Define NCQ Priority sysfs attributes
for SATA devices") introduced support for ATA NCQ priority control for ATA
devices managed by libsas. This commit introduces the ncq_prio_supported
and ncq_prio_enable sysfs device attributes to discover and control the use
of this features, similarly to libata. However, libata publicly declares
these device attributes and export them for use in ATA low level
drivers. This leads to a compilation error when libsas and libata are
built-in due to the double definition:
ld: drivers/ata/libata-sata.o:/home/Linux/scsi/drivers/ata/libata-sata.c:900:
multiple definition of `dev_attr_ncq_prio_supported';

Resolve this problem by directly declaring the libsas attributes instead of
using the DEVICE_ATTR() macro. And for good measure, the device attribute
variables are also renamed.

====================
wireless fixes for v6.9-rc2
The first fixes for v6.9. Ping-Ke Shih now maintains a separate tree
for Realtek drivers, document that in the MAINTAINERS. Plenty of fixes
for both to stack and iwlwifi. Our kunit tests were working only on um
architecture but that's fixed now.

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...

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.

Forcing SMBUS inside the ULP enabling flow leads to sporadic PHY loss on
some systems. It is suspected to be caused by initiating PHY transactions
before the interface settles.
Separating this configuration from the ULP enabling flow and moving it to
the shutdown function allows enough time for the interface to settle and
avoids adding a delay.

On some Meteor Lake systems accessing the PHY via the MDIO interface may
result in an MDI error. This issue happens sporadically and in most cases
a second access to the PHY via the MDIO interface results in success.
As a workaround, introduce a retry counter which is set to 3 on Meteor
Lake systems. The driver will only return an error if 3 consecutive PHY
access attempts fail. The retry mechanism is disabled in specific flows,
where MDI errors are expected.
