Use regfields for number of ALE Entries and Policers.

am65-cpsw can support up to 8 queues at Rx.
Use a macro AM65_CPSW_MAX_RX_QUEUES to indicate that.
As there is only one DMA channel for RX traffic, the
8 queues come as 8 flows in that channel.
By default, we will start with 1 flow as defined by the
macro AM65_CPSW_DEFAULT_RX_CHN_FLOWS.
User can change the number of flows by ethtool like so
'ethtool -L ethx rx <N>'
All traffic will still come on flow 0. To get traffic on
different flows the Classifiers will need to be set up.

Merge kmem_cache_create() refactoring by Christian Brauner.

prerequisity kmem_cache_create_rcu() work.

Merge most of SLUB feature work for 6.12:
- Barrier for pending kfree_rcu() in kmem_cache_destroy() and associated
refactoring of the destroy path (Vlastimil Babka)
- CONFIG_SLUB_RCU_DEBUG to allow KASAN catching UAF bugs in
SLAB_TYPESAFE_BY_RCU caches (Jann Horn)
- kmem_cache_charge() for delayed kmemcg charging (Shakeel Butt)

As kmem_cache_create() became a _Generic() wrapper macro, it currently
has no kerneldoc despite being the main API to use. Add it. Also adjust
kmem_cache_create_usercopy() kerneldoc to indicate it is now a legacy
wrapper.
Also expand the kerneldoc for struct kmem_cache_args, especially for the
freeptr_offset field, where important details were removed with the
removal of kmem_cache_create_rcu().

The TPM event log table is a Linux specific construct, where the data
produced by the GetEventLog() boot service is cached in memory, and
passed on to the OS using an EFI configuration table.
The use of EFI_LOADER_DATA here results in the region being left
unreserved in the E820 memory map constructed by the EFI stub, and this
is the memory description that is passed on to the incoming kernel by
kexec, which is therefore unaware that the region should be reserved.
Even though the utility of the TPM2 event log after a kexec is
questionable, any corruption might send the parsing code off into the
weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY
instead, which is always treated as reserved by the E820 conversion
logic.

If the busy indicator is set, all other fields in CCI should be
clear according to the spec. However, some UCSI implementations do
not follow this rule and report bogus data in CCI along with the
busy indicator. Ignore the contents of CCI if the busy indicator is
set.
If a command timeout is hit it is possible that the EVENT_PENDING
bit is cleared while connector work is still scheduled which can
cause the EVENT_PENDING bit to go out of sync with scheduled connector
work. Check and set the EVENT_PENDING bit on entry to
ucsi_handle_connector_change() to fix this.
Finally, check UCSI_CCI_BUSY before the return code of ->sync_control.
This ensures that the command is cancelled even if ->sync_control
returns an error (most likely -ETIMEDOUT).

The __get_dwc3_maximum_speed() function returns an enum type which, in
this context here, is basically unsigned int. On error cases, it's
supposed to return USB_SPEED_UNKNOWN, but it was accidentally changed to
return negative error codes in commit f93e96c544ca ("usb: dwc3: rtk: use
scoped device node handling to simplify error paths").
There is only one caller and because of the way that the types work out,
returning negative error codes is not a problem. They will be treated
as greater than USB_SPEED_HIGH and ignored as invalid. So this patch
does not affect run time behavior, it's just a clean up.

Improve commit fc88bb116179 ("usb: roles: add lockdep class key to struct
usb_role_switch") as follows:
* Move the lock class key declaration just above the mutex declaration such
that the declaration order of these objects matches their initialization
order.
* Destroy the mutex and lock class key just before these objects are
freed. This makes it easier to verify that the destruction calls happen
after the last use of these objects.
* Instead of switching the mutex key to the dynamic lock class key after
initialization of the mutex has completed, initialize the mutex with the
dynamic lock class key.

With CONFIG_PREEMPT_RT disabled __mutex_init() is a function. With
CONFIG_PREEMPT_RT enabled, __mutex_init() is a macro. I assume this is why
mutex_init() is defined twice as exactly the same macro.
Prepare for introducing a new macro for mutex initialization by combining
the two identical mutex_init() definitions into a single definition. This
patch does not change any functionality because the C preprocessor expands
macros when it encounters the macro name and not when a macro definition
is encountered. See also commit bb630f9f7a7d ("locking/rtmutex: Add mutex

If the FW crashes, L2 driver gets notified and it notifies

device. Add support for re-initialize the RoCE device.
RoCE device is removed and re-attached in the ulp_stop and
ulp_start respectively. The recovery logic expects the RoCE
driver to be registered with L2 driver while its being removed.

The IB layer provides a common interface to store and get net
devices associated to an IB device port (ib_device_set_netdev()
and ib_device_get_netdev()).
Previously, mlx5_ib stored and managed the associated net devices
internally.
Replace internal net device management in mlx5_ib with
ib_device_set_netdev() when attaching/detaching a net device and
ib_device_get_netdev() when retrieving the net device.
Export ib_device_get_netdev().
For mlx5 representors/PFs/VFs and lag creation we replace the netdev
assignments with the IB set/get netdev functions.
In active-backup mode lag the active slave net device is stored in the
lag itself. To assure the net device stored in a lag bond IB device is
the active slave we implement the following:
- mlx5_core: when modifying the slave of a bond we send the internal driver event
MLX5_DRIVER_EVENT_ACTIVE_BACKUP_LAG_CHANGE_LOWERSTATE.
- mlx5_ib: when catching the event call ib_device_set_netdev()
This patch also ensures the correct IB events are sent in switchdev lag.
While at it, when in multiport eswitch mode, only a single IB device is
created for all ports. The said IB device will receive all netdev events
of its VFs once loaded, thus to avoid overwriting the mapping of PF IB
device to PF netdev, ignore NETDEV_REGISTER events if the ib device has
already been mapped to a netdev.

The caller of ib_device_get_netdev() relies on its result to accurately
match a given netdev with the ib device associated netdev.
ib_device_get_netdev returns NULL when the IB device associated
netdev is unregistering, preventing the caller of matching netdevs properly.
Thus, remove this optimization and return the netdev even if
it is undergoing unregistration, allowing matching by the caller.
This change ensures proper netdev matching and reference count handling
by the caller of ib_device_get_netdev/ib_device_set_netdev API.

Consider also the query_vuid cap before enabling the data_direct
functionality.
This may prevent a syndrome from the FW in case the query_vuid command
is not supported. (e.g. migratable VF)

When running over new FW that supports the new memory scheme ODP, set
the cap in the FW to signal the FW we are working in the new scheme.
In the memory scheme ODP the per_transport_service capabilities are RO
for the driver so we skip their setting.
