variable *nplanes is provided by user via system call argument. The
possible value of q_data->fmt->num_planes is 1-3, while the value
of *nplanes can be 1-8. The array access by index i can cause array
out-of-bounds.
Fix this bug by checking *nplanes against the array size.

The iMSI-RX module of the DW PCIe controller provides multiple sets of
MSI_CTRL_INT_i_* registers, and each set is capable of handling 32 MSI
interrupts. However, the fu740 PCIe controller driver only enabled one set
of MSI_CTRL_INT_i_* registers, as the total number of supported interrupts
was not specified.
Set the supported number of MSI vectors to enable all the MSI_CTRL_INT_i_*
registers on the fu740 PCIe core, allowing the system to fully utilize the
available MSI interrupts.

Add an auxiliary virtual bus to model the mlx4 driver structure. The
code is added along the current custom device management logic.
Subsequent patches switch mlx4_en and mlx4_ib to the auxiliary bus and
the old interface is then removed.
Structure mlx4_priv gains a new adev dynamic array to keep track of its
auxiliary devices. Access to the array is protected by the global
mlx4_intf mutex.
Functions mlx4_register_device() and mlx4_unregister_device() are
updated to expose auxiliary devices on the bus in order to load mlx4_en
and/or mlx4_ib. Functions mlx4_register_auxiliary_driver() and
mlx4_unregister_auxiliary_driver() are added to substitute
mlx4_register_interface() and mlx4_unregister_interface(), respectively.
Function mlx4_do_bond() is adjusted to walk over the adev array and
re-adds a specific auxiliary device if its driver sets the
MLX4_INTFF_BONDING flag.

The mlx4_core driver has a logic that allows a sub-driver to set the
MLX4_INTFF_BONDING flag which then causes that function mlx4_do_bond()
asks the sub-driver to fully re-probe a device when its bonding
configuration changes.
Performing this operation is disallowed in mlx4_register_interface()
when it is detected that any mlx4 device is multifunction (SRIOV). The
code then resets MLX4_INTFF_BONDING in the driver flags.
Move this check directly into mlx4_do_bond(). It provides a better
separation as mlx4_core no longer directly modifies the sub-driver flags
and it will allow to get rid of explicitly keeping track of all mlx4
devices by the intf.c code when it is switched to an auxiliary bus.

Function mlx4_en_queue_bond_work() is used in mlx4_en to start a bond
reconfiguration. It gathers data about a new port map setting, takes
a reference on the netdev that triggered the change and queues a work
object on mlx4_en_priv.mdev.workqueue to perform the operation. The
scheduled work is mlx4_en_bond_work() which calls
mlx4_bond()/mlx4_unbond() and consequently mlx4_do_bond().
At the same time, function mlx4_change_port_types() in mlx4_core might
be invoked to change the port type configuration. As part of its logic,
it re-registers the whole device by calling mlx4_unregister_device(),
followed by mlx4_register_device().
The two operations can result in concurrent access to the data about
currently active interfaces on the device.
Functions mlx4_register_device() and mlx4_unregister_device() lock the
intf_mutex to gain exclusive access to this data. The current
implementation of mlx4_do_bond() doesn't do that which could result in
an unexpected behavior. An updated version of mlx4_do_bond() for use
with an auxiliary bus goes and locks the intf_mutex when accessing a new
auxiliary device array.
However, doing so can then result in the following deadlock:
* A two-port mlx4 device is configured as an Ethernet bond.
* One of the ports is changed from eth to ib, for instance, by writing
into a mlx4_port<x> sysfs attribute file.
* mlx4_change_port_types() is called to update port types. It invokes
mlx4_unregister_device() to unregister the device which locks the
intf_mutex and starts removing all associated interfaces.
* Function mlx4_en_remove() gets invoked and starts destroying its first
netdev. This triggers mlx4_en_netdev_event() which recognizes that the
configured bond is broken. It runs mlx4_en_queue_bond_work() which
takes a reference on the netdev. Removing the netdev now cannot
proceed until the work is completed.
* Work function mlx4_en_bond_work() gets scheduled. It calls
mlx4_unbond() -> mlx4_do_bond(). The latter function tries to lock the
intf_mutex but that is not possible because it is held already by
mlx4_unregister_device().
This particular case could be possibly solved by unregistering the
mlx4_en_netdev_event() notifier in mlx4_en_remove() earlier, but it
seems better to decouple mlx4_en more and break this reference order.
Avoid then this scenario by recognizing that the bond reconfiguration
operates only on a mlx4_dev. The logic to queue and execute the bond
work can be moved into the mlx4_core driver. Only a reference on the
respective mlx4_dev object is needed to be taken during the work's
lifetime. This removes a call from mlx4_en that can directly result in
needing to lock the intf_mutex, it remains a privilege of the core
driver.

The mlx4_interface.activate callback was introduced in commit
79857cd31fe7 ("net/mlx4: Postpone the registration of net_device"). It
dealt with a situation when a netdev notifier received a NETDEV_REGISTER
event for a new net_device created by mlx4_en but the same device was
not yet visible to mlx4_get_protocol_dev(). The callback can be removed
now that mlx4_get_protocol_dev() is gone.

Use a notifier to implement mlx4_dispatch_event() in preparation to
switch mlx4_en and mlx4_ib to be an auxiliary device.
A problem is that if the mlx4_interface.event callback was replaced with
something as mlx4_adrv.event then the implementation of
mlx4_dispatch_event() would need to acquire a lock on a given device
before executing this callback. That is necessary because otherwise
there is no guarantee that the associated driver cannot get unbound when
the callback is running. However, taking this lock is not possible
because mlx4_dispatch_event() can be invoked from the hardirq context.
Using an atomic notifier allows the driver to accurately record when it
wants to receive these events and solves this problem.
A handler registration is done by both mlx4_en and mlx4_ib at the end of
their mlx4_interface.add callback. This matches the current situation
when mlx4_add_device() would enable events for a given device
immediately after this callback, by adding the device on the
mlx4_priv.list.

Function mlx4_dispatch_event() takes an 'unsigned long' as its event
parameter. The actual value is none (MLX4_DEV_EVENT_CATASTROPHIC_ERROR),
a pointer to mlx4_eqe (MLX4_DEV_EVENT_PORT_MGMT_CHANGE), or a 32-bit
integer (remaining events).
In preparation to switch mlx4_en and mlx4_ib to be an auxiliary device,
the mlx4_interface.event callback is replaced with a notifier and
function mlx4_dispatch_event() gets updated to invoke
atomic_notifier_call_chain(). This requires forwarding the input 'param'
value from the former function to the latter. A problem is that the
notifier call takes 'void *' as its 'param' value, compared to
'unsigned long' used by mlx4_dispatch_event(). Re-passing the value
would need either punning it to 'void *' or passing down the address of
the input 'param'. Both approaches create a number of unnecessary casts.
Change instead the input 'param' of mlx4_dispatch_event() from
'unsigned long' to 'void *'. A mlx4_eqe pointer can be passed directly,
callers using an int value are adjusted to pass its address.

Simplify the mlx4 driver interface by removing mlx4_get_protocol_dev()
and the associated mlx4_interface.get_dev callbacks. This is done in
preparation to use an auxiliary bus to model the mlx4 driver structure.
The change is motivated by the following situation:
* The mlx4_en interface is being initialized by mlx4_en_add() and
mlx4_en_activate().
* The latter activate function calls mlx4_en_init_netdev() ->
register_netdev() to register a new net_device.
* A netdev event NETDEV_REGISTER is raised for the device.
* The netdev notififier mlx4_ib_netdev_event() is called and it invokes
mlx4_ib_scan_netdevs() -> mlx4_get_protocol_dev() ->
mlx4_en_get_netdev() [via mlx4_interface.get_dev].
This chain creates a problem when mlx4_en gets switched to be an
auxiliary driver. It contains two device calls which would both need to
take a respective device lock.
Avoid this situation by updating mlx4_ib_scan_netdevs() to no longer
call mlx4_get_protocol_dev() but instead to utilize the information
passed in net_device.parent and net_device.dev_port. This data is
sufficient to determine that an updated port is one that the mlx4_ib
driver should take care of and to keep mlx4_ib_dev.iboe.netdevs up to
date.
Following that, update mlx4_ib_get_netdev() to also not call
mlx4_get_protocol_dev() and instead scan all current netdevs to find
find a matching one. Note that mlx4_ib_get_netdev() is called early from
ib_register_device() and cannot use data tracked in
mlx4_ib_dev.iboe.netdevs which is not at that point yet set.
Finally, remove function mlx4_get_protocol_dev() and the
mlx4_interface.get_dev callbacks (only mlx4_en_get_netdev()) as they
became unused.

While injecting PCIe errors to the upstream PCIe switch of
a BCM57810 NIC, system hangs/crashes were observed.
After several calls to bnx2x_tx_timout() complete,
bnx2x_nic_unload() is called to free up HW resources
and bnx2x_napi_disable() is called to release NAPI objects.
Later, when the EEH driver calls bnx2x_io_slot_reset() to
complete the recovery process, bnx2x attempts to disable
NAPI again by calling bnx2x_napi_disable() and freeing
resources which have already been freed, resulting in a
hang or crash.
Introduce a new flag to track the HW resource and NAPI
allocation state, refactor duplicated code into a single
function, check page pool allocation status before freeing,
and reduces debug output when a TX timeout event occurs.

Problem can be reproduced by unloading snd_soc_simple_card, because in
devm_get_clk_from_child() devres data is allocated as `struct clk`, but
devm_clk_release() expects devres data to be `struct devm_clk_state`.
