The icicle kit reference design's v2022.09 release made some changes
to the memory map - including adding the ability to read the fabric
clock controllers via the system controller bus & making the PCI
controller work with upstream Linux.
While the PCI was not working in the v2022.03 design, so nothing is
broken there in terms of backwards compatibility, the fabric clocks
used in the v2022.03 design were chosen by the individual run of the
synthesis tool. In the v2022.09 reference design, the clocks are fixed
to use the "north west" fabric Clock Conditioning Circuitry.
In the v2022.10 release, the memory map on the DDR side is also
changing, so to avoid making a breaking change here twice, jump over the
v2022.09 release and straight to the v2022.10 one.
Make use of a new compatible to denote that v2022.{09,10} reference
design releases are not backwards compatible.

Using smk_of_current() during sk_alloc_security hook leads in
rare cases to a faulty initialization of the security context
of the created socket.
By adding the LSM hook sk_clone_security to SMACK this initialization
fault is corrected by copying the security context of the old socket
pointer to the newly cloned one.

The hctx's run_work may be racing with the elevator switch when
reinitializing hardware queues. The queue is merely frozen in this
context, but that only prevents requests from allocating and doesn't
stop the hctx work from running. The work may get an elevator pointer
that's being torn down, and can result in use-after-free errors and
kernel panics (example below). Use the quiesced elevator switch instead,
and make the previous one static since it is now only used locally.

AF_XDP Tx descriptor cleaning in ice driver currently works in a "lazy"
way - descriptors are not cleaned immediately after send. We rather hold
on with cleaning until we see that free space in ring drops below
particular threshold. This was supposed to reduce the amount of
unnecessary work related to cleaning and instead of keeping the ring
empty, ring was rather saturated.
In AF_XDP realm cleaning Tx descriptors implies producing them to CQ.
This is a way of letting know user space that particular descriptor has
been sent, as John points out in [0].
We tried to implement serial descriptor cleaning which would be used in
conjunction with batched cleaning but it made code base more convoluted
and probably harder to maintain in future. Therefore we step away from
batched cleaning in a current form in favor of an approach where we set
RS bit on every last descriptor from a batch and clean always at the
beginning of ice_xmit_zc().
This means that we give up a bit of Tx performance, but this doesn't
hurt l2fwd scenario which is way more meaningful than txonly as this can
be treaten as AF_XDP based packet generator. l2fwd is not hurt due to
the fact that Tx side is much faster than Rx and Rx is the one that has
to catch Tx up.
FWIW Tx descriptors are still produced in a batched way.

It is useful to be able to recheck dtbs files against a limited set of
DT schema files. This can be accomplished by using differnt
DT_SCHEMA_FILES argument values while rerunning make dtbs_check. However
for some reason if_changed_rule doesn't pick up the rule_dtc changes
(and doesn't retrigger the build).
Fix this by changing if_changed_rule to if_changed_dep and squashing DTC
and dt-validate into a single new command. Then if_changed_dep triggers
on DT_SCHEMA_FILES changes and reruns the build/check.

On guest entry, vcpu->cpu and vcpu->arch.thread_cpu are set after
disabling host irqs. On guest exit there is a window whre tick time
accounting briefly enables irqs before these fields are cleared.
Move them up to ensure they are cleared before host irqs are run.
This is possibly not a problem, but is more symmetric and makes the
fields less surprising.

We used to have a workaround[1] for a hang during migration that was
made ineffective when we converted the decrementer expiry to be
relative to guest timebase.
The point of the workaround was that in the absence of an explicit
decrementer expiry value provided by userspace during migration, KVM
needs to initialize dec_expires to a value that will result in an
expired decrementer after subtracting the current guest timebase. That
stops the vcpu from hanging after migration due to a decrementer
that's too large.
If the dec_expires is now relative to guest timebase, its
initialization needs to be guest timebase-relative as well, otherwise
we end up with a decrementer expiry that is still larger than the
guest timebase.

The iommu_group comes from the struct device that a driver has been bound
to and then created a struct vfio_device against. To keep the iommu layer
sane we want to have a simple rule that only an attached driver should be
using the iommu API. Particularly only an attached driver should hold
ownership.
In VFIO's case since it uses the group APIs and it shares between
different drivers it is a bit more complicated, but the principle still
holds.
Solve this by waiting for all users of the vfio_group to stop before
allowing vfio_unregister_group_dev() to complete. This is done with a new
completion to know when the users go away and an additional refcount to
keep track of how many device drivers are sharing the vfio group. The last
driver to be unregistered will clean up the group.
This solves crashes in the S390 iommu driver that come because VFIO ends
up racing releasing ownership (which attaches the default iommu_domain to
the device) with the removal of that same device from the iommu

with.

====================
devlink: fix order of port and netdev register in drivers
Some of the drivers use wrong order in registering devlink port and
netdev, registering netdev first. That was not intended as the devlink
port is some sort of parent for the netdev. Fix the ordering.
Note that the follow-up patchset is going to make this ordering
mandatory.

Make sure that devlink port is registered first and register netdev
after. Unregister netdev before devlnk port unregister.

To work around a misbehavior of the compiler's ability to see into
composite flexible array structs (as detailed in the coming memcpy()
hardening series[1]), split the memcpy() of the header and the payload
so no false positive run-time overflow warning will be generated. This
split already existed for the "firstfrag" case, so just generalize the
logic further.

As sizeof(hwe->data) can now longer be used as the actual size depends
on foe_entry_size, in commit 9d8cb4c096ab02
("net: ethernet: mtk_eth_soc: add foe_entry_size to mtk_eth_soc") the
use of sizeof(hwe->data) is hence replaced.
However, replacing it with ppe->eth->soc->foe_entry_size is wrong as
foe_entry_size represents the size of the whole descriptor and not just
the 'data' field.
Fix this by subtracing the size of the only other field in the struct
'ib1', so we actually end up with the correct size to be copied to the
data field.
