These two places are rendered like a table in the source (rst) code,
but they are seen as plain text by formatters, and thus are joined
together into a single line, e.g.:
> “root” - a partition root “member” - a non-root member of a partition
This is definitely not what was intended.
To fix, use table formatting, like in other places.

The Allwinner H3 SoC contains an R_INTC that is, as far as we know,
compatible with the R_INTC present in other sun8i SoCs starting with
the A31. Since the R_INTC hardware is undocumented, introduce a new
compatible for the R_INTC variant in this SoC, in case there turns out
to be some difference.

The R_INTC in the A31 and newer sun8i/sun50i SoCs has additional
functionality compared to the sun7i/sun9i NMI controller. Among other
things, it multiplexes access to up to 128 interrupts corresponding to
(and in parallel to) the first 128 GIC SPIs. This means the NMI is no
longer the lowest-numbered hwirq at this irqchip, since it is SPI 32 or
96 (depending on SoC). hwirq 0 now corresponds to SPI 0, usually UART0.
To allow access to all multiplexed IRQs, the R_INTC requires a new
binding where the interrupt number matches the GIC interrupt number.
Otherwise, interrupts with hwirq numbers below the NMI would not be
representable in the device tree.
For simplicity, copy the three-cell GIC binding; this disambiguates
interrupt 0 in the old binding (the NMI) from interrupt 0 in the new
binding (SPI 0) by the number of cells.
Because the H6 R_INTC has a different mapping from multiplexed IRQs to
top-level register bits, it is no longer compatible with the A31 R_INTC.

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>

Some subsystems only have bare tracepoints (a tracepoint with no
associated trace event) to avoid the problem of trace events being an
ABI that can't be changed.
>From bpf presepective, bare tracepoints are what it calls
RAW_TRACEPOINT().
Since bpf assumed there's 1:1 mapping, it relied on hooking to
DEFINE_EVENT() macro to create bpf mapping of the tracepoints. Since
bare tracepoints use DECLARE_TRACE() to create the tracepoint, bpf had
no knowledge about their existence.
By teaching bpf_probe.h to parse DECLARE_TRACE() in a similar fashion to
DEFINE_EVENT(), bpf can find and attach to the new raw tracepoints.
Enabling that comes with the contract that changes to raw tracepoints
don't constitute a regression if they break existing bpf programs.
We need the ability to continue to morph and modify these raw
tracepoints without worrying about any ABI.
Update Documentation/bpf/bpf_design_QA.rst to document this contract.

Commit 91c960b00566 ("bpf: Rename BPF_XADD and prepare to encode other
atomics in .imm") modified the BPF documentation, but missed some ReST
markup.
Hence, make htmldocs warns on Documentation/networking/filter.rst:1053:
WARNING: Inline emphasis start-string without end-string.
Add some minimal markup to address this warning.
Fixes: 91c960b00566 ("bpf: Rename BPF_XADD and prepare to encode other atomics in .imm")

The meta-schema recently gained a definition for the common -supply$
property, which denotes that maxItems is not a valid property. Drop this
to clear up the binding validation error.
