There's really no value in the WARN stack trace etc., the reason
for this happening isn't directly related to the calling function
anyway. Also, syzbot has been observing it constantly, and there's
no way we can resolve it there - those systems are just slow.
Instead print an error message (once) and add a comment about what
really causes this message.

When aoe's rexmit_timer() notices that an aoe target fails to respond to
commands for more than aoe_deadsecs, it calls aoedev_downdev() which
cleans the outstanding aoe and block queues. This can involve sleeping,
such as in blk_mq_freeze_queue(), which should not occur in irq context.
This patch defers that aoedev_downdev() call to the aoe device's
workqueue.

An aoe device's rq_list contains accepted block requests that are
waiting to be transmitted to the aoe target. This queue was added as
part of the conversion to blk_mq. However, the queue was not cleaned out
when an aoe device is downed which caused blk_mq_freeze_queue() to sleep
indefinitely waiting for those requests to complete, causing a hang. This
fix cleans out the queue before calling blk_mq_freeze_queue().

Both PF and VF have rx-vlan-offload enabled, however, the PCVLANR1/2
registers are resources controlled by PF, so VF cannot access these
two registers. Fortunately, the hardware provides SICVLANR1/2 registers
for each SI to reflect the value of PCVLANR1/2 registers. Therefore,
use SICVLANR1/2 instead of PCVLANR1/2. Note that this is not an issue
in actual use, because the current driver does not support custom TPID,
the driver will not access these two registers in actual use, so this
modification is just an optimization.
In addition, since ENETC_RXBD_FLAG_TPID is defined as GENMASK(1, 0),
the possible values are only 0, 1, 2, 3, so the default branch will
never be true, so remove the default branch.

Currently, the MANA driver allocates MSI-X vectors statically based on
MANA_MAX_NUM_QUEUES and num_online_cpus() values and in some cases ends
up allocating more vectors than it needs. This is because, by this time
we do not have a HW channel and do not know how many IRQs should be
allocated.
To avoid this, we allocate 1 MSI-X vector during the creation of HWC and
after getting the value supported by hardware, dynamically add the
remaining MSI-X vectors.

In order to prepare the MANA driver to allocate the MSI-X IRQs
dynamically, we need to enhance irq_setup() to allow skipping
affinitizing IRQs to the first CPU sibling group.
This would be for cases when the number of IRQs is less than or equal
to the number of online CPUs. In such cases for dynamically added IRQs
the first CPU sibling group would already be affinitized with HWC IRQ.

Migrate to new callbacks added by commit 9bb00786fc61 ("net: ethtool:
add dedicated callbacks for getting and setting rxfh fields").
Uniquely, this driver supports only the SET operation. It does not
support GET at all. The SET callback also always returns 0, even
tho it checks a bunch of conditions, and if my quick reading is
right, expects the user to insert filtering rules for given flow
type first? Long story short it seems too convoluted to easily
add the GET as part of the conversion.

====================
CN20K silicon with mbox support
CN20K is the next generation silicon in the Octeon series with various
improvements and new features.
Along with other changes the mailbox communication mechanism between RVU
(Resource virtualization Unit) SRIOV PFs/VFs with Admin function (AF) has
also gone through some changes.
Some of those changes are
- Separate IRQs for mbox request and response/ack.
- Configurable mbox size, default being 64KB.
- Ability for VFs to communicate with RVU AF instead of going through
parent SRIOV PF.
Due to more memory requirement due to configurable mbox size, mbox memory
will now have to be allocated by
- AF (PF0) for communicating with other PFs and all VFs in the system.
- PF for communicating with it's child VFs.
On previous silicons mbox memory was reserved and configured by firmware.
This patch series add basic mbox support for AF (PF0) <=> PFs and
PF <=> VFs. AF <=> VFs communication and variable mbox size support will
come in later.
Patch #1 Supported co-existance of bit encoding PFs and VFs in 16-bit
hardware pcifunc format between CN20K silicon and older octeon
series. Also exported PF,VF masks and shifts present in mailbox
module to all other modules.
Patch #2 Added basic mbox operation APIs and structures to support both
CN20K and previous version of silicons.
Patch #3 This patch adds support for basic mbox infrastructure
implementation for CN20K silicon in AF perspective. There are
few updates w.r.t MBOX ACK interrupt and offsets in CN20k.
Patch #4 Added mbox implementation between NIC PF and AF for CN20K.
Patch #5 Added mbox communication support between AF and AF's VFs.
Patch #6 This patch adds support for MBOX communication between NIC PF and
its VFs.

This implementation uses separate trigger interrupts for request,
response MBOX messages against using trigger message data in CN10K.
This patch adds support for basic mbox implementation for CN20K
from AF side.

This patch adds basic mbox operation APIs and structures to add support
for mbox module on CN20k silicon. There are few CSR offsets, interrupts
changed between CN20k and prior Octeon series of devices.

Number of RVU PFs on CN20K silicon have increased to 96 from maximum
of 32 that were supported on earlier silicons. Every RVU PF and VF is
identified by HW using a 16bit PF_FUNC value. Due to the change in
Max number of PFs in CN20K, the bit encoding of this PF_FUNC has changed.
This patch handles the change by using helper functions(using silicon
check) to use PF,VF masks and shifts to support both new silicon CN20K,
OcteonTx series. These helper functions are used in different modules.
Also moved the NIX AF register offset macros to other files which
will be posted in coming patches.

We can only pass negative error codes to bch2_err_str(); if it's a
positive integer it's not an error and we trip an assert.

Commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still
active") ensured that active jobs are returned to the pending list when
extending the timeout. However, it didn't use the pending list's lock to
manipulate the list, which causes a race condition as the scheduler's
workqueues are running.
Hold the lock while manipulating the scheduler's pending list to prevent
a race.

A path exists in a particular snapshot: we should do the pathwalk in the
snapshot ID of the inode we started from, _not_ change snapshot ID as we
walk inodes and dirents.

We can easily go from inode number -> path now, which makes for more

When we find a directory connectivity problem, we should do the repair
in the oldest snapshot that has the issue - so that we don't end up
duplicating work or making a real mess of things.
Oldest snapshot IDs have the highest integer value, so - just walk
inodes in reverse order.
