The GPIO interrupt controller on the espressobin board only supports edge interrupts.
If one enables the use of hardware interrupts in the device tree for the 88E6341, it is
possible to miss an edge. When this happens, the INTn pin on the Marvell switch is
stuck low and no further interrupts occur.
I found after adding debug statements to mv88e6xxx_g1_irq_thread_work() that there is
a race in handling device interrupts (e.g. PHY link interrupts). Some interrupts are
directly cleared by reading the Global 1 status register. However, the device interrupt
flag, for example, is not cleared until all the unmasked SERDES and PHY ports are serviced.
This is done by reading the relevant SERDES and PHY status register.
The code only services interrupts whose status bit is set at the time of reading its status
register. If an interrupt event occurs after its status is read and before all interrupts
are serviced, then this event will not be serviced and the INTn output pin will remain low.
This is not a problem with polling or level interrupts since the handler will be called
again to process the event. However, it's a big problem when using level interrupts.
The fix presented here is to add a loop around the code servicing switch interrupts. If
any pending interrupts remain after the current set has been handled, we loop and process
the new set. If there are no pending interrupts after servicing, we are sure that INTn has
gone high and we will get an edge when a new event occurs.
Tested on espressobin board.

phylib enables interrupts before phy_start() has been called, and if
we receive an interrupt in a non-started state, the interrupt handler
returns IRQ_NONE. This causes problems with at least one Marvell chip
as reported by Andrew.
Fix this by handling interrupts the same as in phy_mac_interrupt(),
basically always running the phylib state machine. It knows when it
has to do something and when not.
This change allows to handle interrupts gracefully even if they
occur in a non-started state.

The 802.3bz specification, based on previous by the NBASET alliance,
defines the 2.5GBaseT and 5GBaseT link modes for ethernet traffic on
cat5e, cat6 and cat7 cables.
These mode integrate with the already defined C45 MDIO PMA/PMD registers
set that added 10G support, by defining some previously reserved bits,
and adding a new register (2.5G/5G Extended abilities).
This commit adds the required definitions in include/uapi/linux/mdio.h
to support these modes, and detect when a link-partner advertises them.
It also adds support for these mode in the generic C45 PHY
infrastructure.

Marvell 10G PHY driver has a generic way of initializing the supported
link modes by reading the PHY's C45 PMA abilities. This can be made
generic, since these registers are part of the 802.3 specifications.
This commit extracts the config_init link_mode initialization code from
marvell10g and uses it to introduce the genphy_c45_pma_read_abilities
function.
Only PMA modes are read, it's still up to the caller to set the Pause
parameters.

Currently mlx5 driver creates xdp redirect hw queues unconditionally on
netdevice open, This is great until someone starts redirecting XDP traffic
via ndo_xdp_xmit on mlx5 device and changes the device configuration at
the same time, this might cause crashes, since the other device's napi
is not aware of the mlx5 state change (resources un-availability).
To fix this we must synchronize with other devices napi's on the system.
Added a new flag under mlx5e_priv to determine XDP TX resources are
available, set/clear it up when necessary and use synchronize_rcu()
when the flag is turned off, so other napi's are in-sync with it, before
we actually cleanup the hw resources.
The flag is tested prior to committing to transmit on mlx5e_xdp_xmit, and
it is sufficient to determine if it safe to transmit or not. The other
two internal flags (MLX5E_STATE_OPENED and MLX5E_SQ_STATE_ENABLED) become
unnecessary. Thus, they are removed from data path.

When EEH is injected and PCI bus stalls, mlx5's pci error detect
function is called to deactivate the command interface and tear down
the device. The issue is that there can be a thread that already
passed MLX5_DEVICE_STATE_INTERNAL_ERROR check, it will send the command
and stuck in the wait_func.
Solution:
Add function mlx5_cmd_flush to disable command interface and clear all
the pending commands. When device state is set to
MLX5_DEVICE_STATE_INTERNAL_ERROR, call mlx5_cmd_flush to ensure all
pending threads waiting for firmware commands completion are terminated.

New channels are applied to the priv channels only after they
are successfully opened. Then, the indirection table should be built
according to the new number of channels.
Currently, such build is preformed independently of whether the
channels opening is successful, and is not reverted on failure.
The bug is caused due to removal of rss params from channels struct
and moving it to priv struct. That change cause to independency between
channels and rss params.
This causes a crash on a later point, when accessing rqn of a non
existing channel.
This patch fixes it by moving the indirection table build right before
switching the priv channels to new channels struct, after the new set of
channels was successfully opened.

VFIO TCE IOMMU v2 owns IOMMU tables. When we detach an IOMMU group from
a container, we need to unset these tables from the group which we do by
calling unset_window(). We also unset tables when removing a DMA window
via the VFIO_IOMMU_SPAPR_TCE_REMOVE ioctl.
The window removal checks if the table actually exists (hidden inside
tce_iommu_find_table()) but the group detaching does not so the user
may see duplicating messages:
pci 0009:03 : [PE# fd] Removing DMA window #0
pci 0009:03 : [PE# fd] Removing DMA window #1
pci 0009:03 : [PE# fd] Removing DMA window #0
pci 0009:03 : [PE# fd] Removing DMA window #1
At the moment this is not a problem as the second invocation
of unset_window() writes zeroes to the HW registers again and exits early
as there is no table.

Commit bb364890323cca ("mmc: meson-gx: Free irq in release() callback")
changed the _probe code to use request_threaded_irq() instead of
devm_request_threaded_irq().
Unfortunately this removes a fallback for the interrupt name:
devm_request_threaded_irq() uses the device name as fallback if the
given IRQ name is NULL. request_threaded_irq() has no such fallback,
thus /proc/interrupts shows "(null)" instead.
Explicitly pass the dev_name() so we get the IRQ name shown in
/proc/interrupts again.
While here, also fix the indentation of the request_threaded_irq()
parameter list.

When an alternate driver (vfio-ap) has bound an ap queue and this
binding is revised the ap queue device is in an intermittent
state not bound to any driver. The internal state variable
covered this with the state AP_STATE_BORKED which is also used to
reflect broken devices. When now an ap bus scan runs such a
device is destroyed and on the next scan reconstructed.
So a stress test with high frequency switching the queue driver
between the default and the vfio-ap driver hit this gap and the
queue was removed until the next ap bus scan. This fix now
introduces another state for the in-between condition for a queue
momentary not bound to a driver and so the ap bus scan function
skips this device instead of removing it.
Also some very slight but maybe helpful debug feature messages
come with this patch - in particular a message showing that a
broken card/queue device will get removed.

The problem is that the default for MQ is not to gather entropy, whereas
the default for the legacy queue was always to gather it. The original
attempt to fix entropy gathering for rotational disks under MQ added an
else branch in sd_read_block_characteristics(). Unfortunately, the entire
check isn't reached if the device has no characteristics VPD page. Since
this page was only introduced in SBC-3 and its optional anyway, most less
expensive rotational disks don't have one, meaning they all stopped
gathering entropy when we made MQ the default. In a wholly unrelated
change, openssl and openssh won't function until the random number
generator is initialised, meaning lots of people have been seeing large
delays before they could log into systems with default MQ kernels due to
this lack of entropy, because it now can take tens of minutes to initialise
the kernel random number generator.
The fix is to set the non-rotational and add-randomness flags
unconditionally early on in the disk initialization path, so they can be
reset only if the device actually reports being non-rotational via the VPD
page.

sync_request_write no longer submits writes to a Faulty device. This has
the unfortunate side effect that bitmap bits can be incorrectly cleared
if a recovery is interrupted (previously, end_sync_write would have
prevented this). This means the next recovery may not copy everything
it should, potentially corrupting data.
Add a function for doing the proper md_bitmap_end_sync, called from

The current opt_inst_list operations inside team_nl_cmd_options_set()
is too complex to track:
LIST_HEAD(opt_inst_list);
nla_for_each_nested(...) {
list_for_each_entry(opt_inst, &team->option_inst_list, list) {
if (__team_option_inst_tmp_find(&opt_inst_list, opt_inst))
continue;
list_add(&opt_inst->tmp_list, &opt_inst_list);
}
}
team_nl_send_event_options_get(team, &opt_inst_list);
as while we retrieve 'opt_inst' from team->option_inst_list, it could
be added to the local 'opt_inst_list' for multiple times. The
__team_option_inst_tmp_find() doesn't work, as the setter
team_mode_option_set() still calls team->ops.exit() which uses
->tmp_list too in __team_options_change_check().
Simplify the list operations by moving the 'opt_inst_list' and
team_nl_send_event_options_get() into the nla_for_each_nested() loop so
that it can be guranteed that we won't insert a same list entry for
multiple times. Therefore, __team_option_inst_tmp_find() can be removed
too.

Fix race condition between ena_update_on_link_change() and
ena_restore_device().
This race can occur if link notification arrives while the driver
is performing a reset sequence. In this case link can be set up,
enabling the device, before it is fully restored. If packets are
sent at this time, the driver might access uninitialized data
structures, causing kernel crash.
Move the clearing of ENA_FLAG_ONGOING_RESET and netif_carrier_on()
after ena_up() to ensure the device is ready when link is set up.

Instead of copying fields one by one copy the whole structure. This way there's
no need to modify the function every time we add a new field to the struct.

When adding a new value to enum wmi_service it's very easy to miss that the new
value should be also added to wmi_service_name() mapping function. Modify the
function so that GCC can now warn about this:
drivers/net/wireless/ath/ath10k/wmi.h:385:2: warning: enumeration value 'WMI_SERVICE_FOO' not handled in switch [-Wswitch]
And also add a reminder to the enum.

If supported, update transmit airtime in mac80211 with the airtime
values reported by the firmware. TX airtime of the PPDU is reported
via HTT data TX completion indication message.
A new service flag 'WMI_SERVICE_REPORT_AIRTIME' is added to advertise
the firmware support. For firmwares which do not support this feature,
TX airtime is calculated in the driver using TX bitrate.

Multicast/broadcast traffic destined for a particular vlan group will
always be encrypted in software. To enable dynamic VLANs, it requires
driver support for sending software encrypted packets.
In ath10k, sending software encrypted frames is allowed only when we insmod
the driver with cryptmode param set to 1, this configuration disables
hardware crypto and enables RAW mode implicitly. Since, enabling raw
mode has performance impact, this cannot be considered as an ideal
solution for supporting VLANs in the driver.
As an alternative take, in this approach, cryptographic keys for
unicast traffic (per peer PTKs) and keys for non-vlan group traffic
will be configured in hardware, allowing hardware encryption for unicast
and non-vlan group traffic. Only vlan group traffic will be encrypted in
software and pushed to the target with encap mode set to RAW in the TX
descriptors.
Not all firmwares can support this type of key configuration(having few
keys installed in hardware and few only in software); for this purpose a
new WMI service flag "WMI_SERVICE_PER_PACKET_SW_ENCRYPT" is introduced to
advertise this support.
Also, adding the logic required to send sw encrypted frames in raw mode.
