According to the document of napi, there is no rx process when the
budget is 0. Therefore, r8152_poll() has to return 0 directly when the
budget is equal to 0.

Commit 0a0e2ea642f6 ("ACPI: processor: Move MWAIT quirk out of
acpi_processor.c") moved the MWAIT quirk code into arch/x86 but left
calls to it in the ACPI PDC processor code that is shared with Itanium,
breaking the latter build.
Since the quirk is specific to a certain x86-based platform, stub out
the function acpi_proc_quirk_mwait_check() when building for ia64.

====================
Fixes for SJA1105 DSA FDB regressions
A report by Yanan Yang has prompted an investigation into the sja1105
driver's behavior w.r.t. multicast. The report states that when adding
multicast L2 addresses with "bridge mdb add", only the most recently
added address works - the others seem to be overwritten. This is solved
by patch 3/5 (with patch 2/5 as a dependency for it).
Patches 4/5 and 5/5 fix a series of race conditions introduced during
the same patch set as the bug above, namely this one:
https://patchwork.kernel.org/project/netdevbpf/cover/20211024171757.3753288-1-vladimir.oltean@nxp.com/
Finally, patch 1/5 fixes an issue found ever since the introduction of
multicast forwarding offload in sja1105, which is that the multicast
addresses are visible (with the "self" flag) in "bridge fdb show".

Currently, when we add the first sja1105 port to a bridge with
vlan_filtering 1, then we sometimes see this output:
sja1105 spi2.2: port 4 failed to read back entry for be:79:b4:9e:9e:96 vid 3088: -ENOENT
sja1105 spi2.2: Reset switch and programmed static config. Reason: VLAN filtering
sja1105 spi2.2: port 0 failed to add be:79:b4:9e:9e:96 vid 0 to fdb: -2
It is because sja1105_fdb_add() runs from the dsa_owq which is no longer
serialized with switch resets since it dropped the rtnl_lock() in the
blamed commit.
Either performing the FDB accesses before the reset, or after the reset,
is equally fine, because sja1105_static_fdb_change() backs up those
changes in the static config, but FDB access during reset isn't ok.
Make sja1105_static_config_reload() take the fdb_lock to fix that.

sja1105_fdb_add() runs from the dsa_owq, and sja1105_port_mcast_flood()
runs from switchdev_deferred_process_work(). Prior to the blamed commit,
they used to be indirectly serialized through the rtnl_lock(), which
no longer holds true because dsa_owq dropped that.
So, it is now possible that we traverse the static config BLK_IDX_L2_LOOKUP
elements concurrently compared to when we change them, in
sja1105_static_fdb_change(). That is not ideal, since it might result in
data corruption.
Introduce a mutex which serializes accesses to the hardware FDB and to
the static config elements for the L2 Address Lookup table.
I can't find a good reason to add locking around sja1105_fdb_dump().
I'll add it later if needed.

entry
The commit cited in Fixes: did 2 things: it refactored the read-back
polling from sja1105_dynamic_config_read() into a new function,
sja1105_dynamic_config_wait_complete(), and it called that from
sja1105_dynamic_config_write() too.
What is problematic is the refactoring.
The refactored code from sja1105_dynamic_config_poll_valid() works like
the previous one, but the problem is that it uses another packed_buf[]
SPI buffer, and there was code at the end of sja1105_dynamic_config_read()
which was relying on the read-back packed_buf[]:
/* Don't dereference possibly NULL pointer - maybe caller
* only wanted to see whether the entry existed or not.
*/
if (entry)
ops->entry_packing(packed_buf, entry, UNPACK);
After the change, the packed_buf[] that this code sees is no longer the
entry read back from hardware, but the original entry that the caller
passed to the sja1105_dynamic_config_read(), packed into this buffer.
This difference is the most notable with the SJA1105_SEARCH uses from
sja1105pqrs_fdb_add() - used for both fdb and mdb. There, we have logic
added by commit 728db843df88 ("net: dsa: sja1105: ignore the FDB entry
for unknown multicast when adding a new address") to figure out whether
the address we're trying to add matches on any existing hardware entry,
with the exception of the catch-all multicast address.
That logic was broken, because with sja1105_dynamic_config_read() not
working properly, it doesn't return us the entry read back from
hardware, but the entry that we passed to it. And, since for multicast,
a match will always exist, it will tell us that any mdb entry already
exists at index=0 L2 Address Lookup table. It is index=0 because the
caller doesn't know the index - it wants to find it out, and
sja1105_dynamic_config_read() does:
if (index < 0) { // SJA1105_SEARCH
/* Avoid copying a signed negative number to an u64 */
cmd.index = 0; // <- this
cmd.search = true;
} else {
cmd.index = index;
cmd.search = false;
}
So, to the caller of sja1105_dynamic_config_read(), the returned info
looks entirely legit, and it will add all mdb entries to FDB index 0.
There, they will always overwrite each other (not to mention,
potentially they can also overwrite a pre-existing bridge fdb entry),
and the user-visible impact will be that only the last mdb entry will be
forwarded as it should. The others won't (will be flooded or dropped,
depending on the egress flood settings).
Fixing is a bit more complicated, and involves either passing the same
packed_buf[] to sja1105_dynamic_config_wait_complete(), or moving all
the extra processing on the packed_buf[] to
sja1105_dynamic_config_wait_complete(). I've opted for the latter,
because it makes sja1105_dynamic_config_wait_complete() a bit more
self-contained.

sja1105_dynamic_config_poll_valid()
Currently, sja1105_dynamic_config_wait_complete() returns either 0 or
-ETIMEDOUT, because it just looks at the read_poll_timeout() return code.
There will be future changes which move some more checks to
sja1105_dynamic_config_poll_valid(). It is important that we propagate
their exact return code (-ENOENT, -EINVAL), because callers of
sja1105_dynamic_config_read() depend on them.

Currently, when a new fdb entry is added (with both ports of the
ADIN2111 bridged), the driver configures the MAC filters for the wrong
port, which results in the forwarding being done by the host, and not
actually hardware offloaded.
The ADIN2111 offloads the forwarding by setting filters on the
destination MAC address of incoming frames. Based on these, they may be
routed to the other port. Thus, if a frame has to be forwarded from port
1 to port 2, the required configuration for the ADDR_FILT_UPRn register
should set the APPLY2PORT1 bit (instead of APPLY2PORT2, as it's
currently the case).

Kyril reports that crashkernels fail to work on confidential VMs that
rely on the unaccepted memory table, and this appears to be caused by
the fact that it is not considered part of the set of firmware tables
that the crashkernel needs to map.
This is an oversight, and a result of the use of the EFI_LOADER_DATA
memory type for this table. The correct memory type to use for any
firmware table is EFI_ACPI_RECLAIM_MEMORY (including ones created by the
EFI stub), even though the name suggests that is it specific to ACPI.
ACPI reclaim means that the memory is used by the firmware to expose
information to the operating system, but that the memory region has no
special significance to the firmware itself, and the OS is free to
reclaim the memory and use it as ordinary memory if it is not interested
in the contents, or if it has already consumed them. In Linux, this
memory is never reclaimed, but it is always covered by the kernel direct
map and generally made accessible as ordinary memory.
On x86, ACPI reclaim memory is translated into E820_ACPI, which the
kexec logic already recognizes as memory that the crashkernel may need
to to access, and so it will be mapped and accessible to the booting
crash kernel.

CONFIG_EFI_RUNTIME_MAP needs to be enabled in order for kexec to be able
to provide the required information about the EFI runtime mappings to
the incoming kernel, regardless of whether kexec_load() or
kexec_file_load() is being used. Without this information, kexec boot in
EFI mode is not possible.
The CONFIG_EFI_RUNTIME_MAP option is currently directly configurable if
CONFIG_EXPERT is enabled, so that it can be turned on for debugging
purposes even if KEXEC is not enabled. However, the upshot of this is
that it can also be disabled even when it shouldn't.
So tweak the Kconfig declarations to avoid this situation.

Ensure that we always set the corresponding bits in PxSCTL.IPM, such that
a device is not allowed to initiate transitions to power states which are
unsupported by the HBA.
DevSleep is always initiated by the HBA, however, for completeness, set the
corresponding bit in PxSCTL.IPM such that agressive link power management
cannot transition to DevSleep if DevSleep is not supported.
sata_link_scr_lpm() is used by libahci, ata_piix and libata-pmp.
However, only libahci has the ability to read the CAP/CAP2 register to see

regressions on ata_piix or libata-pmp, create flags that indicate that the

on non-OF system and shouldn't be an issue.
Add mod_devicetable.h include.
While at it, remove trailing comma in the terminator entry for OF/ID
table.

As explained in errata sheet, in section "2.14.5 Truncation of SPI output
signals after EOT event":
On STM32MP1x, EOT interrupt can be thrown before the true end of
communication.
So we add a delay of a half period to wait the real end of the
transmission.

Commit ac950278b087 ("ASoC: add N cpus to M codecs dai link support")
added an additional local params in __soc_pcm_hw_params, for the CPU
side of the DAI. The snd_pcm_hw_params struct is pretty large (604
bytes) and keeping two local copies of it can make the stack frame
really large.
It is worth noting the variables are in separate code blocks so for
some optimisation levels in the compiler these will get automatically
combined keeping the stack frame reasonable. But better to manually
combine them to cover all cases.
Add a single local variable for __soc_pcm_hw_params and use in both
loops to shrink the stack frame.

Driver remove() must call pm_runtime_dont_use_autosuspend().
Drivers that call pm_runtime_use_autosuspend() must disable
it in driver remove(). Unfortunately until recently this was
only mentioned in 1 line in a 900+ line document so most
people hadn't noticed this. It has only recently been added
to the kerneldoc of pm_runtime_use_autosuspend().

Tegra audio graph card has many DAI links which connects internal
AHUB modules and external audio codecs. Since these are DPCM links,
hw_params() call in the machine driver happens for each connected
BE link and PLLA is updated every time. This is not really needed
for all links as only I/O link DAIs derive respective clocks from
PLLA_OUT0 and thus from PLLA. Hence add checks to limit the clock
updates to DAIs over I/O links.
This found to be fixing a DMIC clock discrepancy which is suspected
to happen because of back to back quick PLLA and PLLA_OUT0 rate
updates. This was observed on Jetson TX2 platform where DMIC clock
ended up with unexpected value.

Pull drm ci scripts from Dave Airlie:
"This is a bunch of ci integration for the freedesktop gitlab instance
where we currently do upstream userspace testing on diverse sets of
GPU hardware. From my perspective I think it's an experiment worth
going with and seeing how the benefits/noise playout keeping these
files useful.
Ideally I'd like to get this so we can do pre-merge testing on PRs
eventually.
Below is some info from danvet on why we've ended up making the
decision and how we can roll it back if we decide it was a bad plan.
Why in upstream?
- like documentation, testcases, tools CI integration is one of these
things where you can waste endless amounts of time if you
accidentally have a version that doesn't match your source code
- but also like the above, there's a balance, this is the initial cut
of what we think makes sense to keep in sync vs out-of-tree,
probably needs adjustment
- gitlab supports out-of-repo gitlab integration and that's what's
been used for the kernel in drm, but it results in per-driver
fragmentation and lots of duplicated effort. the simple act of
smashing an arbitrary winner into a topic branch already started
surfacing patches on dri-devel and sparking good cross driver team
discussions
Why gitlab?
- it's not any more shit than any of the other CI
- drm userspace uses it extensively for everything in userspace, we
have a lot of people and experience with this, including
integration of hw testing labs
- media userspace like gstreamer is also on gitlab.fd.o, and there's
discussion to extend this to the media subsystem in some fashion
Can this be shared?
- there's definitely a pile of code that could move to scripts/ if
other subsystem adopt ci integration in upstream kernel git. other
bits are more drm/gpu specific like the igt-gpu-tests/tools
integration
- docker images can be run locally or in other CI runners
Will we regret this?
- it's all in one directory, intentionally, for easy deletion
- probably 1-2 years in upstream to see whether this is worth it or a
Big Mistake. that's roughly what it took to _really_ roll out solid
CI in the bigger userspace projects we have on gitlab.fd.o like
mesa3d"

The access to page pool `cache' array and the `count' variable
is not locked. Page pool cache access is fine as long as there
is only one consumer per pool.
octeontx2 driver fills in rx buffers from page pool in NAPI context.
If system is stressed and could not allocate buffers, refiiling work
will be delegated to a delayed workqueue. This means that there are
two cosumers to the page pool cache.
Either workqueue or IRQ/NAPI can be run on other CPU. This will lead
to lock less access, hence corruption of cache pool indexes.
To fix this issue, NAPI is rescheduled from workqueue context to refill
rx buffers.

interface names
Starting with v197, systemd uses predictable interface network names,
the traditional interface naming scheme (eth0) is deprecated, therefore
it cannot be assumed that the eth0 interface exists on the host.
This modification makes the bind_bhash test program run in a separate
network namespace and no longer needs to consider the name of the
network interface on the host.
