Pruning a bit more the includes dependency tree. Building this thing on
lots of containers takes time, we better reduce the time per build, each
container is doing 6 builds when clang and clang-devel are available,
and the plan is to do a 'make -C tools/perf build-test' that have many
more.
Also helps when doing normal development, as touching some random file
will have a much reduced chance of triggering lots of rebuilds.

This un-breaks lookups in sets that have the 'dynamic' flag set.
Given this active example configuration:
table filter {
set set1 {
type ipv4_addr
size 64
flags dynamic,timeout
timeout 1m
}
chain input {
type filter hook input priority 0; policy accept;
}
}
... this works:
nft add rule ip filter input add @set1 { ip saddr }
-> whenever rule is triggered, the source ip address is inserted
into the set (if it did not exist).
This won't work:
nft add rule ip filter input ip saddr @set1 counter
Error: Could not process rule: Operation not supported
In other words, we can add entries to the set, but then can't make
matching decision based on that set.
That is just wrong -- all set backends support lookups (else they would
not be very useful).
The failure comes from an explicit rejection in nft_lookup.c.
Looking at the history, it seems like NFT_SET_EVAL used to mean
'set contains expressions' (aka. "is a meter"), for instance something like
nft add rule ip filter input meter example { ip saddr limit rate 10/second }
or
nft add rule ip filter input meter example { ip saddr counter }
The actual meaning of NFT_SET_EVAL however, is
'set can be updated from the packet path'.
'meters' and packet-path insertions into sets, such as
'add @set { ip saddr }' use exactly the same kernel code (nft_dynset.c)
and thus require a set backend that provides the ->update() function.
The only set that provides this also is the only one that has the
NFT_SET_EVAL feature flag.
Removing the wrong check makes the above example work.
While at it, also fix the flag check during set instantiation to
allow supported combinations only.

The laptop has a combined jack to attach headsets on the right.
The BIOS encodes them as two different colored jacks at the front,
but otherwise it seems to be configured ok. But any adaption of
the pins config on its own doesn't fix the jack detection to work
in Linux. Still Windows works correct.
This is somehow fixed by chaining ALC256_FIXUP_ASUS_HEADSET_MODE,
which seems to register the microphone jack as a headset part and
also results in fixing jack sensing, visible in dmesg as:
-snd_hda_codec_realtek hdaudioC0D0: Mic=0x19
+snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19
[ Actually the essential change is the location of the jack; the
driver created "Front Mic Jack" without the matching volume / mute
control element due to its jack location, which confused PA.

Linux supports both the original ARMv6 level (early ARM1136) and ARMv6K
(later ARM1136, ARM1176 and ARM11mpcore).
ast2500 falls into the second categoy, being based on arm1176jzf-s.
This is enabled by default when using ARCH_MULTI_V6, so we should
not 'select CPU_V6'.
Removing this will lead to more efficient use of atomic instructions.

The documentation of skew values for the KSZ9021 PHY was misleading
because the driver implementation followed the erroneous information
given in the original KSZ9021 datasheet before it was corrected in
revision 1.2 (Feb 2014). It is probably too late to correct the driver
now because of the many existing device trees, so instead this just
corrects the documentation to explain that what you actually get is not
what you might think when looking at the device tree.

Disabling multicast filtering from NCSI if it is supported. As it
should not filter any multicast packets. In current code, multicast
filter is enabled and with an exception of optional field supported
by device are disabled filtering.
Mainly I see if goal is to disable filtering for IPV6 packets then let
it disabled for every other types as well. As we are seeing issues with
LLDP not working with this enabled filtering. And there are other issues
with IPV6.
By Disabling this multicast completely, it is working for both IPV6 as
well as LLDP.

Pull drm updates from Dave Airlie:
"This is the main pull request for 5.4-rc1 merge window. I don't think
there is anything outstanding so next week should just be fixes, but
we'll see if I missed anything. I landed some fixes earlier in the

Modify the calling convention for the iomap_dio_rw ->end_io() callback.
Rather than passing either dio->error or dio->size as the 'size' argument,
instead pass both the dio->error and the dio->size value separately.
In the instance that an error occurred during a write, we currently cannot
determine whether any blocks have been allocated beyond the current EOF and
data has subsequently been written to these blocks within the ->end_io()
callback. As a result, we cannot judge whether we should take the truncate
failed write path. Having both dio->error and dio->size will allow us to
perform such checks within this callback.

Without CONFIG_THERMAL, the driver fails to link as it calls
iwl_mvm_send_temp_report_ths_cmd() unconditionally. Fix this
by making that function available, but do almost nothing but
send the empty firmware command to enable CT-kill reporting.
While at it, also fix that function itself to not error out
when the thermal zone hasn't been initialized, but instead
just send the empty firmware command in this case as well.

Each iteration of for_each_child_of_node puts the previous node, but
in the case of a goto from the middle of the loop, there is no put,
thus causing a memory leak. Add an of_node_put before three such goto
statements.

Pull orangefs updates from Mike Marshall:
"A fix and a cleanup.
The fix: way back in the stone age (2003) mode was set to the magic
number "755" in what is now fs/orangefs/namei.c(orangefs_symlink).
Łukasz Wrochna reported it and Artur Świgoń sent in a patch to change
it to octal. Maybe it shouldn't be a magic number at all but rather
something like "S_IRWXU | S_IRGRP | S_IXGRP | S_IROTH | S_IXOTH"...
cleanup: Colin Ian King found a redundant assignment and sent in a
patch to remove it"

binary 'or' of some line noise macros. So 0755 is preferred over
trying to spell it out using "helpful" macros - Linus ]

As for the rest of the mount API conversions in -next, some of them
belong in the individual trees (e.g. binderfs one should definitely go
through android folks, after getting redone on top of their changes).
I'm going to drop those and send the rest (trivial ones + stuff ACKed
by maintainers) in a separate series - by that point they are
independent from each other.
Some stuff has already migrated into individual trees (NFS conversion,
for example, or FUSE stuff, etc.); those presumably will go through
the regular merges from corresponding trees."

When handling a GPU page fault addr_to_drm_mm_node() is used to
translate the GPU address to a buffer object. However it is possible for
the buffer object to be freed after the function has returned resulting
in a use-after-free of the BO.
Change addr_to_drm_mm_node to return the panfrost_gem_object with an
extra reference on it, preventing the BO from being freed until after
the page fault has been handled.

The panfrost driver requests a supply using regulator_get_optional()
but both the name of the supply and the usage pattern suggest that it is
being used for the main power for the device and is not at all optional
for the device for function, there is no meaningful handling for absent
supplies. Such regulators should use the vanilla regulator_get()
interface, it will ensure that even if a supply is not described in the
system integration one will be provided in software.

Pull y2038 vfs updates from Arnd Bergmann:
"Add inode timestamp clamping.
This series from Deepa Dinamani adds a per-superblock minimum/maximum
timestamp limit for a file system, and clamps timestamps as they are
written, to avoid random behavior from integer overflow as well as
having different time stamps on disk vs in memory.
At mount time, a warning is now printed for any file system that can
represent current timestamps but not future timestamps more than 30
years into the future, similar to the arbitrary 30 year limit that was
added to settimeofday().
This was picked as a compromise to warn users to migrate to other file
systems (e.g. ext4 instead of ext3) when they need the file system to
survive beyond 2038 (or similar limits in other file systems), but not
get in the way of normal usage"

The reason is that the code in collect_expired_timers() uses jiffies
unprotected:
if (next_event > jiffies)
base->clk = jiffies;
As the compiler is allowed to reload the value base->clk can advance
between the check and the store and in the worst case advance farther than
next event. That causes the timer expiry to be delayed until the wheel
pointer wraps around.
Convert the code to use READ_ONCE()
