sock.h is pretty heavily used (5k objects rebuilt on x86 after
it's touched). We can drop the include of filter.h from it and
add a forward declaration of struct sk_filter instead.
This decreases the number of rebuilt objects when bpf.h
is touched from ~5k to ~1k.
There's a lot of missing includes this was masking. Primarily
in networking tho, this time.

The PWR_OFF bit needs to be set in order to power off properly, without
hanging PMIC. This bit needs to be set early in order to allow thermal
protection of NVIDIA Terga SoCs to power off hardware properly, otherwise
a battery re-plug may be needed on some devices to recover after the hang.

The Intel Crystal Cove PMIC has 2 different variants, one for use with
Bay Trail (BYT) SoCs and one for use with Cherry Trail (CHT) SoCs.
So far we have been using an ACPI _HRV check to differentiate between
the 2, but at least on the Microsoft Surface 3, which is a CHT device,
the wrong _HRV value is reported by ACPI.
So instead switch to a CPU-ID check which prevents us from relying on
the possibly wrong ACPI _HRV value.

Many DSDTs for Kaby Lake and Kaby Lake Refresh models contain a
_SB.PCI0.GEXP ACPI Device node describing an I2C attached PCA953x
GPIO expander.
This seems to be something which is copy and pasted from the DSDT
from some reference design since this ACPI Device is present even on
models where no such GPIO expander is used at all, such as on the
Microsoft Surface Go & Go 2.
This ACPI Device is a problem because it contains a SystemMemory
OperationRegion which covers the MMIO for the I2C4 I2C controller. This
causes the MFD cell for the I2C4 controller to not be instantiated due
to a resource conflict, requiring the use of acpi_enforce_resources=lax
to work around this.
I have done an extensive analysis of all the ACPI tables on the
Microsoft Surface Go and the _SB.PCI0.GEXP ACPI Device's methods are
not used by any code in the ACPI tables, neither are any of them
directly called by any Linux kernel code. This is unsurprising since
running i2cdetect on the I2C4 bus shows that there is no GPIO
expander chip present on these devices at all.
This commit adds a PCI subsystem vendor:device table listing PCI devices
where it is known to be safe to ignore resource conflicts with ACPI
declared SystemMemory regions.
This makes the I2C4 bus work out of the box on the Microsoft Surface
Go & Go 2, which is necessary for the cameras on these devices to work.

Playback pop is observed and the root cause is the reference clock
provided by MT8195 is diabled before RT5682 finishes the control flow.
To ensure the reference clock supplied to RT5682 is disabled after RT5682
finishes all register controls. We replace BCLK with MCLK for RT5682
reference clock, and makes use of set_bias_level_post to handle MCLK
which guarantees MCLK is off after all RT5682 register access.

In case of an error in mlx5e_set_features(), 'netdev->features' must be
updated with the correct state of the device to indicate which features
were updated successfully.
To do that we maintain a copy of 'netdev->features' and update it after
successful feature changes, so we can assign it to back to
'netdev->features' if needed.
However, since not all netdev features are handled by the driver (e.g.
GRO/TSO/etc), some features may not be updated correctly in case of an
error updating another feature.
For example, while requesting to disable TSO (feature which is not
handled by the driver) and enable HW-GRO, if an error occurs during
HW-GRO enable, 'oper_features' will be assigned with 'netdev->features'
and HW-GRO turned off. TSO will remain enabled in such case, which is a
bug.
To solve that, instead of using 'netdev->features' as the baseline of
'oper_features' and changing it on set feature success, use 'features'
instead and update it in case of errors.

session requests to server. There is racy issue using
sess->ntlmssp.cryptkey on N connection : 1 session. So authetication
failed using wrong cryptkey on some session. This patch move cryptkey
to ksmbd_conn structure to use each cryptkey on connection.

Set RSS capable in FSCTL_QUERY_NETWORK_INTERFACE_INFO if netdev has
multi tx queues. And add ksmbd_compare_user() to avoid racy condition
issue in ksmbd_free_user(). because windows client is simultaneously used
to send session setup requests for multichannel connection.

* dpu plane state cleanup in prep for multirect
* dpu debugfs cleanup (and moving things to atomic_print_state) in prep
for multirect
* dp support for sc7280
* struct_mutex removal
* include more GMU state in gpu devcore dumps
* add support for a506
* remove old eDP sub-driver (never was used in any upstream supported
devices and modern things with eDP will use DP sub-driver instead)
* debugfs to disable hw gpu hang detect for (igt tests)
* debugfs for dumping display hw state
* and the usual assortment of cleanup and bug fixes
There still seems to be a timing issue with dpu, showing up on sc7180
devices, after the bridge probe-order change. Ie. things work great if
loglevel is high enough (or enough debug options are enabled, etc).
We'll continue to debug this in the new year.

It is all well described by Stephen Rothwell who initially spotted that:
----------------------------->8----------------------------
After merging the origin tree, today's linux-next build (arc
haps_hs_smp_defconfig+kselftest) produced these warnings:
arch/arc/include/asm/perf_event.h:126:27: warning: 'arc_pmu_cache_map' defined but not used [-Wunused-const-variable=]
arch/arc/include/asm/perf_event.h:91:27: warning: 'arc_pmu_ev_hw_map' defined but not used [-Wunused-const-variable=]
Introduced by commit 0dd450fe13 ("ARC: Add perf support for ARC700 cores")
The 2 static arrays should be moved into arch/arc/kernel/perf_event.c
(the only place that uses them). We get the warning because perf_event.h
is also included by arch/arc/kernel/unaligned.c.
----------------------------->8----------------------------
Could be easily reproduced by running make with "W=1" on any up-to-date
sources, when extra warnings get enabled (in particular
"-Wunused-const-variable"), otherwise disabled by default in the top-level
Makefile as "These warnings generated too much noise in a regular build".

Ubuntu reports incorrect kernel version through uname(), which on older
kernels leads to kprobe BPF programs failing to load due to the version
check mismatch.
Accommodate Ubuntu's quirks with LINUX_VERSION_CODE by using
Ubuntu-specific /proc/version_code to fetch major/minor/patch versions
to form LINUX_VERSION_CODE.
While at it, consolide libbpf's kernel version detection code between
libbpf.c and libbpf_probes.c.

Refactor PT_REGS macros definitions in bpf_tracing.h to avoid excessive
duplication. We currently have classic PT_REGS_xxx() and CO-RE-enabled
PT_REGS_xxx_CORE(). We are about to add also _SYSCALL variants, which
would require excessive copying of all the per-architecture definitions.
Instead, separate architecture-specific field/register names from the
final macro that utilize them. That way for upcoming _SYSCALL variants
we'll be able to just define x86_64 exception and otherwise have one
common set of _SYSCALL macro definitions common for all architectures.
