Merge fixes for the int340x thermal driver handling of MSI IRQs:
- Fix MSI error path cleanup in int340x, allow it to work with a
subset of thermal MSI IRQs if some of them are not working and
make it free all MSI IRQs on module exit (Srinivas Pandruvada).
* thermal-intel:
thermal: intel: int340x: Free MSI IRQ vectors on module exit

Say there are 3 trip points A, B, C sorted in ascending temperature
order with no hysteresis. If the zone temerature is exactly equal to
B, thermal_zone_set_trips() will set the boundaries to A and C and the
hardware will not catch any crossing of B (either way) until either A
or C is crossed and the boundaries are changed.
To avoid that, use non-strict inequalities when comparing the trip
threshold to the zone temperature in thermal_zone_set_trips().
In the example above, it will cause both boundaries to be set to B,
which is desirable because an interrupt will trigger when the zone
temperature becomes different from B regardless of which way it goes.
That will allow a new interval to be set depending on the direction of
the zone temperature change.

Commit 7ba5ca32fe6e ("ALSA: firewire-lib: operate for period elapse event
in process context") removed the process context workqueue from
amdtp_domain_stream_pcm_pointer() and update_pcm_pointers() to remove
its overhead.
With RME Fireface 800, this lead to a regression since
Kernels 5.14.0, causing an AB/BA deadlock competition for the
substream lock with eventual system freeze under ALSA operation:
thread 0:
* (lock A) acquire substream lock by
snd_pcm_stream_lock_irq() in
snd_pcm_status64()
* (lock B) wait for tasklet to finish by calling
tasklet_unlock_spin_wait() in
tasklet_disable_in_atomic() in
ohci_flush_iso_completions() of ohci.c
thread 1:
* (lock B) enter tasklet
* (lock A) attempt to acquire substream lock,
waiting for it to be released:
snd_pcm_stream_lock_irqsave() in
snd_pcm_period_elapsed() in
update_pcm_pointers() in
process_ctx_payloads() in
process_rx_packets() of amdtp-stream.c

ice: fix AF_XDP ZC timeout and concurrency issues
Maciej Fijalkowski says:
Changes included in this patchset address an issue that customer has
been facing when AF_XDP ZC Tx sockets were used in combination with flow
control and regular Tx traffic.
After executing:
ethtool --set-priv-flags $dev link-down-on-close on
ethtool -A $dev rx on tx on
launching multiple ZC Tx sockets on $dev + pinging remote interface (so
that regular Tx traffic is present) and then going through down/up of
$dev, Tx timeout occurred and then most of the time ice driver was unable
to recover from that state.
These patches combined together solve the described above issue on
customer side. Main focus here is to forbid producing Tx descriptors when
either carrier is not yet initialized or process of bringing interface
down has already started.

Tighten csum_start and csum_offset checks in virtio_net_hdr_to_skb
for GSO packets.
The function already checks that a checksum requested with
VIRTIO_NET_HDR_F_NEEDS_CSUM is in skb linear. But for GSO packets
this might not hold for segs after segmentation.
Syzkaller demonstrated to reach this warning in skb_checksum_help
offset = skb_checksum_start_offset(skb);
ret = -EINVAL;
if (WARN_ON_ONCE(offset >= skb_headlen(skb)))
By injecting a TSO packet:

Mitigate with stricter input validation.
csum_offset: for GSO packets, deduce the correct value from gso_type.
This is already done for USO. Extend it to TSO. Let UFO be:
udp[46]_ufo_fragment ignores these fields and always computes the
checksum in software.
csum_start: finding the real offset requires parsing to the transport
header. Do not add a parser, use existing segmentation parsing. Thanks
to SKB_GSO_DODGY, that also catches bad packets that are hw offloaded.
Again test both TSO and USO. Do not test UFO for the above reason, and
do not test UDP tunnel offload.
GSO packet are almost always CHECKSUM_PARTIAL. USO packets may be
CHECKSUM_NONE since commit 10154dbded6d6 ("udp: Allow GSO transmit
from devices with no checksum offload"), but then still these fields
are initialized correctly in udp4_hwcsum/udp6_hwcsum_outgoing. So no
need to test for ip_summed == CHECKSUM_PARTIAL first.
This revises an existing fix mentioned in the Fixes tag, which broke
small packets with GSO offload, as detected by kselftests.

Commit 708405f3e56e ("net: phy: aquantia: wait for the GLOBAL_CFG to
start returning real values") introduced a workaround for an issue
observed on aqr115c. However there were never any reports of it
happening on other models and the workaround has been reported to cause
and issue on aqr113c (and it may cause the same on any other model not
supporting 10M mode).
Let's limit the impact of the workaround to aqr113, aqr113c and aqr115c
and poll the 100M GLOBAL_CFG register instead as both models are known
to support it correctly.

The mbigen interrupt chip has its per node registers located in a
contiguous region of page sized chunks. The code maps them into virtual
address space as a contiguous region and determines the address of a node
by using the node ID as index.

This works correctly up to 10 nodes, but then fails because the 11th's
array slot is used for the MGN_CLEAR registers.

This clarifies the rules for min()/max()/clamp() type checking and makes
them a much more efficient macro expansion.
In particular, we now look at the type and range of the inputs to see
whether they work together, generating a mask of acceptable comparisons,
and then just verifying that the inputs have a shared case:
- an expression with a signed type can be used for
(1) signed comparisons
(2) unsigned comparisons if it is statically known to have a
non-negative value
- an expression with an unsigned type can be used for
(3) unsigned comparison
(4) signed comparisons if the type is smaller than 'int' and thus
the C integer promotion rules will make it signed anyway
Here rule (1) and (3) are obvious, and rule (2) is important in order to
allow obvious trivial constants to be used together with unsigned
values.
Rule (4) is not necessarily a good idea, but matches what we used to do,
and we have extant cases of this situation in the kernel. Notably with
bcachefs having an expression like
min(bch2_bucket_sectors_dirty(a), ca->mi.bucket_size)
where bch2_bucket_sectors_dirty() returns an 's64', and
'ca->mi.bucket_size' is of type 'u16'.
Technically that bcachefs comparison is clearly sensible on a C type
level, because the 'u16' will go through the normal C integer promotion,
and become 'int', and then we're comparing two signed values and
everything looks sane.
However, it's not entirely clear that a 'min(s64,u16)' operation makes a
lot of conceptual sense, and it's possible that we will remove rule (4).
After all, the _reason_ we have these complicated type checks is exactly
that the C type promotion rules are not very intuitive.
But at least for now the rule is in place for backwards compatibility.
Also note that rule (2) existed before, but is hugely relaxed by this
commit. It used to be true only for the simplest compile-time
non-negative integer constants. The new macro model will allow cases
where the compiler can trivially see that an expression is non-negative
even if it isn't necessarily a constant.
For example, the amdgpu driver does
min_t(size_t, sizeof(fru_info->serial), pia[addr] & 0x3F));
because our old 'min()' macro would see that 'pia[addr] & 0x3F' is of
type 'int' and clearly not a C constant expression, so doing a 'min()'
with a 'size_t' is a signedness violation.
Our new 'min()' macro still sees that 'pia[addr] & 0x3F' is of type
'int', but is smart enough to also see that it is clearly non-negative,
and thus would allow that case without any complaints.

On the off chance that clock value ends up being too high (by means
of skl_ddi_calculate_wrpll() having been called with big enough
value of crtc_state->port_clock * 1000), one possible consequence
may be that the result will not be able to fit into signed int.
Fix this issue by moving conversion of clock parameter from kHz to Hz
into the body of skl_ddi_calculate_wrpll(), as well as casting the
same parameter to u64 type while calculating the value for AFE clock.
This both mitigates the overflow problem and avoids possible erroneous
integer promotion mishaps.

Some arch + compiler combinations report a potentially unused variable
location in btrfs_lookup_dentry(). This is a false alert as the variable
is passed by value and always valid or there's an error. The compilers
cannot probably reason about that although btrfs_inode_by_name() is in
the same file.

iucv_sever_path() is called from process context and from bh context.
iucv->path is used as indicator whether somebody else is taking care of
severing the path (or it is already removed / never existed).
This needs to be done with atomic compare and swap, otherwise there is a
small window where iucv_sock_close() will try to work with a path that has
already been severed and freed by iucv_callback_connrej() called by
iucv_tasklet_fn().

The cros_ec_get_host_command_version_mask() function requires that the
caller must have ec_dev->lock mutex before calling it. This requirement
was not met and as a result it was possible that two commands were sent
to the device at the same time.
The problem was observed while using UART backend which doesn't use any
additional locks, unlike SPI backend which locks the controller until
response is received.

The place for link training is in the encoder's atomic_enable
helper. Remove all related tests from other helper ASTDP functions;
especially ast_astdp_is_connected(), which tests HPD status.
DP link training is controlled by the firmware. A status flag reports
success or failure. The process can be fragile on Aspeed hardware. Moving
the test from connector detection to the atomic_enable allows for several
retries and a longer timeout.

====================
mptcp: fix inconsistent backup usage
In all the MPTCP backup related tests, the backup flag was set on one
side, and the expected behaviour is to have both sides respecting this
decision. That's also the "natural" way, and what the users seem to
expect.
On the scheduler side, only the 'backup' field was checked, which is
supposed to be set only if the other peer flagged a subflow as backup.
But in various places, this flag was also set when the local host
flagged the subflow as backup, certainly to have the expected behaviour
mentioned above.
Patch 1 modifies the packet scheduler to check if the backup flag has
been set on both directions, not to change its behaviour after having
applied the following patches. That's what the default packet scheduler
should have done since the beginning in v5.7.
Patch 2 fixes the backup flag being mirrored on the MPJ+SYN+ACK by
accident since its introduction in v5.7. Instead, the received and sent
backup flags are properly distinguished in requests.
Patch 3 stops setting the received backup flag as well when sending an
MP_PRIO, something that was done since the MP_PRIO support in v5.12.
Patch 4 adds related and missing MIB counters to be able to easily check
if MP_JOIN are sent with a backup flag. Certainly because these counters
were not there, the behaviour that is fixed by patches here was not
properly verified.
Patch 5 validates the previous patch by extending the MPTCP Join
selftest.
Patch 6 fixes the backup support in signal endpoints: if a signal
endpoint had the backup flag, it was not set in the MPJ+SYN+ACK as
expected. It was only set for ongoing connections, but not future ones
as expected, since the introduction of the backup flag in endpoints in
v5.10.
Patch 7 validates the previous patch by extending the MPTCP Join
selftest as well.

Before the previous commit, 'signal' endpoints with the 'backup' flag
were ignored when sending the MP_JOIN.
The MPTCP Join selftest has then been modified to validate this case:
the "single address, backup" test, is now validating the MP_JOIN with a
backup flag as it is what we expect it to do with such name. The
previous version has been kept, but renamed to "single address, switch
to backup" to avoid confusions.
The "single address with port, backup" test is also now validating the
MPJ with a backup flag, which makes more sense than checking the switch
to backup with an MP_PRIO.
The "mpc backup both sides" test is now validating that the backup flag
is also set in MP_JOIN from and to the addresses used in the initial
subflow, using the special ID 0.
The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

There was a support for signal endpoints, but only when the endpoint's
flag was changed during a connection. If an endpoint with the signal and
backup was already present, the MP_JOIN reply was not containing the
backup flag as expected.
That's confusing to have this inconsistent behaviour. On the other hand,
the infrastructure to set the backup flag in the SYN + ACK + MP_JOIN was
already there, it was just never set before. Now when requesting the
local ID from the path-manager, the backup status is also requested.
Note that when the userspace PM is used, the backup flag can be set if
the local address was already used before with a backup flag, e.g. if
the address was announced with the 'backup' flag, or a subflow was
created with the 'backup' flag.

A peer can notify the other one that a subflow has to be treated as
"backup" by two different ways: either by sending a dedicated MP_PRIO
notification, or by setting the backup flag in the MP_JOIN handshake.
The selftests were previously monitoring the former, but not the latter.
This is what is now done here by looking at these new MIB counters when
validating the 'backup' cases:
MPTcpExtMPJoinSynBackupRx
MPTcpExtMPJoinSynAckBackupRx

Without such counters, it is difficult to easily debug issues with MPJ
not having the backup flags on production servers.
This is not strictly a fix, but it eases to validate the following
patches without requiring to take packet traces, to query ongoing
connections with Netlink with admin permissions, or to guess by looking
at the behaviour of the packet scheduler. Also, the modification is self
contained, isolated, well controlled, and the increments are done just
after others, there from the beginning. It looks then safe, and helpful
to backport this.

When sending an MP_JOIN + SYN + ACK, it is possible to mark the subflow
as 'backup' by setting the flag with the same name. Before this patch,
the backup was set if the other peer set it in its MP_JOIN + SYN
request.
It is not correct: the backup flag should be set in the MPJ+SYN+ACK only
if the host asks for it, and not mirroring what was done by the other
peer. It is then required to have a dedicated bit for each direction,
similar to what is done in the subflow context.

The 'mptcp_subflow_context' structure has two items related to the
backup flags:
- 'backup': the subflow has been marked as backup by the other peer
- 'request_bkup': the backup flag has been set by the host
Before this patch, the scheduler was only looking at the 'backup' flag.
That can make sense in some cases, but it looks like that's not what we
wanted for the general use, because either the path-manager was setting
both of them when sending an MP_PRIO, or the receiver was duplicating
the 'backup' flag in the subflow request.
Note that the use of these two flags in the path-manager are going to be
fixed in the next commits, but this change here is needed not to modify
the behaviour.

Power up the ASTDP connector for connection status detection if the
connector is not active. Keep it powered if a display is attached.
This fixes a bug where the connector does not come back after
disconnecting the display. The encoder's atomic_disable turns off
power on the physical connector. Further HPD reads will fail,
thus preventing the driver from detecting re-connected displays.
For connectors that are actively used, only test the HPD flag without
touching power.

The original patch added two columns in the flat-table of Luma-Only
Image Formats, without updating hints to latex: above it. This results
in wrong column count in the output of Sphinx's latex builder.
Fix it.

Commit 4670c8c3fb04 ("media: ipu-bridge: Fix Kconfig dependencies") changed
how IPU_BRIDGE dependencies are handled for all drivers, but the IPU6
variant was added the old way, which causes build time warnings when I2C is
turned off:
WARNING: unmet direct dependencies detected for IPU_BRIDGE
Depends on [n]: MEDIA_SUPPORT [=m] && PCI [=y] && MEDIA_PCI_SUPPORT [=y] && (ACPI [=y] || COMPILE_TEST [=y]) && I2C [=n]
Selected by [m]:
- VIDEO_INTEL_IPU6 [=m] && MEDIA_SUPPORT [=m] && PCI [=y] && MEDIA_PCI_SUPPORT [=y] && (ACPI [=y] || COMPILE_TEST [=y]) && VIDEO_DEV [=m] && X86 [=y] && X86_64 [=y] && HAS_DMA [=y]
To make it consistent with the other IPU drivers as well as avoid this
warning, change the 'select' into 'depends on'.
