Introduce API to add and delete an auxiliary device for an SF.
Each SF has its own dedicated window in the PCI BAR 2.
SF device is similar to PCI PF and VF that supports multiple class of
devices such as net, rdma and vdpa.
SF device will be added or removed in subsequent patch during SF
devlink port function state change command.
A subfunction device exposes user supplied subfunction number which will
be further used by systemd/udev to have deterministic name for its
netdevice and rdma device.
An mlx5 subfunction auxiliary device example:
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
$ devlink port show
pci/0000:06:00.0/65535: type eth netdev ens2f0np0 flavour physical port 0 splittable false
$ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
pci/0000:08:00.0/32768: type eth netdev eth6 flavour pcisf controller 0 pfnum 0 sfnum 88 external false splittable false
function:
hw_addr 00:00:00:00:00:00 state inactive opstate detached
$ devlink port show ens2f0npf0sf88

The IPA driver uses the remoteproc SSR notifier now, rather than the
temporary IPA notification system used initially. As a result it no
longer needs a property identifying the modem subsystem DT node.
Use GIC_SPI rather than 0 in the example interrupt definition.

Otherwise a malicious user could (ab)use the "recalculate" feature
that makes dm-integrity calculate the checksums in the background
while the device is already usable. When the system restarts before all
checksums have been calculated, the calculation continues where it was
interrupted even if the recalculate feature is not requested the next
time the dm device is set up.
Disable recalculating if we use internal_hash or journal_hash with a
key (e.g. HMAC) and we don't have the "legacy_recalculate" flag.
This may break activation of a volume, created by an older kernel,
that is not yet fully recalculated -- if this happens, the user should
add the "legacy_recalculate" flag to constructor parameters.

The device link device's name was of the form:
<supplier-dev-name>--<consumer-dev-name>
This can cause name collision as reported here [1] as device names are
not globally unique. Since device names have to be unique within the
bus/class, add the bus/class name as a prefix to the device names used to
construct the device link device name.
So the devuce link device's name will be of the form:
<supplier-bus-name>:<supplier-dev-name>--<consumer-bus-name>:<consumer-dev-name>

This comes from an end-user request, where they're running multiple VMs on
hosts with bonded interfaces connected to some interest switch topologies,
where 802.3ad isn't an option. They're currently running a proprietary
solution that effectively achieves load-balancing of VMs and bandwidth
utilization improvements with a similar form of transmission algorithm.
Basically, each VM has it's own vlan, so it always sends its traffic out
the same interface, unless that interface fails. Traffic gets split
between the interfaces, maintaining a consistent path, with failover still
available if an interface goes down.
Unlike bond_eth_hash(), this hash function is using the full source MAC
address instead of just the last byte, as there are so few components to
the hash, and in the no-vlan case, we would be returning just the last
byte of the source MAC as the hash value. It's entirely possible to have
two NICs in a bond with the same last byte of their MAC, but not the same
MAC, so this adjustment should guarantee distinct hashes in all cases.
This has been rudimetarily tested to provide similar results to the
proprietary solution it is aiming to replace. A patch for iproute2 is also
posted, to properly support the new mode there as well.

- reword description
- add new compatible 'ti,am642-cpsw-nuss'
- allow 2 external ports child nodes
- add missed 'assigned-clock' props

The CPTS clock is usually a clk-mux which allows to select CPTS reference
clock by using 'assigned-clock-parents', 'assigned-clocks' DT properties.
Also depending on integration the power-domains has to be specified to
enable CPTS IP.
Hence add 'assigned-clock-parents', 'assigned-clocks' and 'power-domains'
properties to the CPTS DT bindings to avoid dtbs_check warnings:
cpts@310d0000: 'assigned-clock-parents', 'assigned-clocks' do not match any of the regexes: 'pinctrl-[0-9]+'
cpts@310d0000: 'power-domains' does not match any of the regexes: 'pinctrl-[0-9]+'

A subsequent patch will add additional atomic operations. These new
operations will use the same opcode field as the existing XADD, with
the immediate discriminating different operations.
In preparation, rename the instruction mode BPF_ATOMIC and start
calling the zero immediate BPF_ADD.
This is possible (doesn't break existing valid BPF progs) because the
immediate field is currently reserved MBZ and BPF_ADD is zero.
All uses are removed from the tree but the BPF_XADD definition is
kept around to avoid breaking builds for people including kernel
headers.

Pull networking fixes from Jakub Kicinski:
"We have a few fixes for long standing issues, in particular Eric's fix
to not underestimate the skb sizes, and my fix for brokenness of
register_netdevice() error path. They may uncover other bugs so we
will keep an eye on them. Also included are Willem's fixes for
kmap(_atomic).
Looking at the "current release" fixes, it seems we are about one rc
behind a normal cycle. We've previously seen an uptick of "people had
run their test suites" / "humans actually tried to use new features"
fixes between rc2 and rc3.
Summary:
Current release - regressions:
- fix feature enforcement to allow NETIF_F_HW_TLS_TX if IP_CSUM &&
IPV6_CSUM
- dcb: accept RTM_GETDCB messages carrying set-like DCB commands if
user is admin for backward-compatibility
- selftests/tls: fix selftests build after adding ChaCha20-Poly1305
Current release - always broken:
- ppp: fix refcount underflow on channel unbridge
- bnxt_en: clear DEFRAG flag in firmware message when retry flashing
- smc: fix out of bound access in the new netlink interface
Previous releases - regressions:
- fix use-after-free with UDP GRO by frags
- mptcp: better msk-level shutdown
- rndis_host: set proper input size for OID_GEN_PHYSICAL_MEDIUM
request
- i40e: xsk: fix potential NULL pointer dereferencing
Previous releases - always broken:
- skb frag: kmap_atomic fixes
- avoid 32 x truesize under-estimation for tiny skbs
- fix issues around register_netdevice() failures
- udp: prevent reuseport_select_sock from reading uninitialized socks
- dsa: unbind all switches from tree when DSA master unbinds
- dsa: clear devlink port type before unregistering slave netdevs
- can: isotp: isotp_getname(): fix kernel information leak
- mlxsw: core: Thermal control fixes
- ipv6: validate GSO SKB against MTU before finish IPv6 processing
- stmmac: use __napi_schedule() for PREEMPT_RT
- net: mvpp2: remove Pause and Asym_Pause support

The bmc150-accel-i2c.c driver has an "_accel" suffix for the
compatibles of BMC150 and BMI055. This is necessary because BMC150
contains both accelerometer (bosch,bmc150_accel) and magnetometer
(bosch,bmc150_magn) and therefore "bosch,bmc150" would be ambiguous.
However, the binding documentation suggests using "bosch,bmc150".
Add the "_accel" suffix for BMC150 and BMI055 so the binding docs
match what is expected by the driver.

Cited patch below blocked the TLS TX device offload unless HW_CSUM
is set. This broke devices that use IP_CSUM && IP6_CSUM.
Here we fix it.
Note that the single HW_TLS_TX feature flag indicates support for
both IPv4/6, hence it should still be disabled in case only one of
(IP_CSUM | IPV6_CSUM) is set.

Arnd found a randconfig that produces the warning:
arch/x86/entry/thunk_64.o: warning: objtool: missing symbol for insn at
offset 0x3e
when building with LLVM_IAS=1 (Clang's integrated assembler). Josh
notes:
With the LLVM assembler not generating section symbols, objtool has no
way to reference this code when it generates ORC unwinder entries,
because this code is outside of any ELF function.
The limitation now being imposed by objtool is that all code must be
contained in an ELF symbol. And .L symbols don't create such symbols.
So basically, you can use an .L symbol *inside* a function or a code
segment, you just can't use the .L symbol to contain the code using a
SYM_*_START/END annotation pair.
Fangrui notes that this optimization is helpful for reducing image size
when compiling with -ffunction-sections and -fdata-sections. I have
observed on the order of tens of thousands of symbols for the kernel
images built with those flags.
A patch has been authored against GNU binutils to match this behavior
of not generating unused section symbols ([1]), so this will
also become a problem for users of GNU binutils once they upgrade to 2.36.
Omit the .L prefix on a label so that the assembler will emit an entry
into the symbol table for the label, with STB_LOCAL binding. This
enables objtool to generate proper unwind info here with LLVM_IAS=1 or
GNU binutils 2.36+.

It's useful to be able to test non-vector event channel delivery, to make
sure Linux will work properly on older Xen which doesn't have it.
It's also useful for those working on Xen and Xen-compatible hypervisors,
because there are guest kernels still in active use which use PCI INTX
even when vector delivery is available.

Amlogic Meson G12A, G12B and SM1 SoCs have a more advanced RGMII RX
delay register which allows picoseconds precision. Deprecate the old
"amlogic,rx-delay-ns" in favour of the generic "rx-internal-delay-ps"
property.
For older SoCs the only known supported values were 0ns and 2ns. The new
SoCs have support for RGMII RX delays between 0ps and 3000ps in 200ps
steps.
Don't carry over the description for the "rx-internal-delay-ps" property
and inherit that from ethernet-controller.yaml instead.

used to be a CONFIG_PACKET_MMAP config symbol that depended on
CONFIG_PACKET. The text still implies that PACKET_MMAP can be disabled.
Remove that from the text, as well as reference to old kernel versions.
Also, drop reference to broken link to information for pre 2.6.5
kernels.

PMIC pm8009 has special revision (P=1) made for sm8250 platform. The
major difference is the S2 regulator which supplies 0.95 V instead of
2.848V. Add special compatibility string for this chip revision.
The datasheet calls the chip just pm8009-1, so use the same name.

During the process of converting the documentation to reST, some links
were converted using the following wrong syntax (and sometimes using %20
instead of spaces):
`Display text <#section-name-in-html>`__
This syntax isn't valid according to the docutils' spec [1], but more
importantly, it is specific to HTML, since it uses '#' to link to an
HTML anchor.
The right syntax would instead use a docutils hyperlink reference as the
embedded URI to point to the section [2], that is:
`Display text <Section Name_>`__
This syntax works in both HTML and PDF.
The LaTeX toolchain doesn't mind the HTML anchor syntax when generating
the pdf documentation (make pdfdocs), that is, the build succeeds but
the links don't work, but that syntax causes errors when trying to build

The API documentation states that general error codes are not detailed, but
errors with specific meanings are. On arm64, KVM_RUN can return error
numbers with a different meaning than what is described by POSIX or the C99
standard (as taken from man 3 errno).
Absent from the newly documented error codes is ERANGE which can be
returned when making a change to the EL2 stage 1 tables if the address is
larger than the largest supported input address. Assuming no bugs in the
implementation, that is not possible because the input addresses which are
mapped are the result of applying the macro kern_hyp_va() on kernel virtual
addresses.

Merge KASAN updates from Andrew Morton.
This adds a new hardware tag-based mode to KASAN. The new mode is
similar to the existing software tag-based KASAN, but relies on arm64
Memory Tagging Extension (MTE) to perform memory and pointer tagging
(instead of shadow memory and compiler instrumentation).

This change updates KASAN documentation to reflect the addition of boot
parameters and also reworks and clarifies some of the existing sections,
in particular: defines what a memory granule is, mentions quarantine,
makes Kunit section more readable.

This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.
The new mode won't be using shadow memory, but will still use the concept
of memory granules. Each memory granule maps to a single metadata entry:
8 bytes per one shadow byte for generic mode, 16 bytes per one shadow byte
for software tag-based mode, and 16 bytes per one allocation tag for
hardware tag-based mode.
Rename KASAN_SHADOW_SCALE_SIZE to KASAN_GRANULE_SIZE, and
KASAN_SHADOW_MASK to KASAN_GRANULE_MASK.
Also use MASK when used as a mask, otherwise use SIZE.
No functional changes.

ability to get struct clk pointers from a struct clk_hw so that clk providers
can consume the clks they provide, if they need to do something like that. This
has been a long missing part of the clk provider API that will help us move
away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are
added for the clk_set_rate() "range" functions, similar to the tracepoints we
already have for clk_set_rate() and we added a column to debugfs to help
developers understand the hardware enable state of clks in case firmware or
bootloader state is different than what is expected. Overall the core changes
are mostly improving the clk driver writing experience.
At the driver level, we have the usual collection of driver updates and new
drivers for new SoCs. This time around the Qualcomm folks introduced a good
handful of clk drivers for various parts of three or four SoCs. The SiFive
folks added a new clk driver for their FU740 SoCs, coming in second on the
diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that
for various new features. One last thing to note in the driver area is that the
i.MX driver has gained a new binding to support SCU clks after being on the
list for many months. It uses a two cell binding which is sort of rare in clk
DT bindings. Beyond that we have the usual set of driver fixes and tweaks that
come from more testing and finding out that some configuration was wrong or
that a driver could support being built as a module.
Core:
- Add some trace points for clk_set_rate() "range" functions
- Add hardware enable information to clk_summary debugfs
- Replace clk-provider.h with of_clk.h when possible
- Add devm variant of clk_notifier_register()
- Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw
New Drivers:
- Bindings for Canaan K210 SoC clks
- Support for SiFive FU740 PRCI
- Camera clks on Qualcomm SC7180 SoCs
- GCC and RPMh clks on Qualcomm SDX55 SoCs
- RPMh clks on Qualcomm SM8350 SoCs
- LPASS clks on Qualcomm SM8250 SoCs
Updates:
- DVFS support for AT91 clk driver
- Update git repo branch for Renesas clock drivers
- Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U
- Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E
- Stop using __raw_*() I/O accessors in Renesas clk drivers
- One more conversion of DT bindings to json-schema
- Make i.MX clk-gate2 driver more flexible
- New two cell binding for i.MX SCU clks
- Drop of_match_ptr() in i.MX8 clk drivers
