If the device is connected with SDIO bus, it can wake up the host using
either the SDIO controller (that requires MMC_PM_WAKE_SDIO_IRQ
capability) or the out-of-bound IRQ. This patch allows both.
Obviously, the SDIO controller must be able to keep the SDIO device

The NMI controller in the Allwinner A523 is almost compatible to the
previous versions of this IP, but requires the extra bit 31 to be set in
the enable register to actually report the NMI.
Add a mask to allow such an enable bit to be specified, and add this to
the per-SoC data structure. As this struct was just for different register
offsets so far, it was consequently named "reg_offs", which is now no
longer applicable, so rename this to the more generic "data" on the way,
and move the existing offsets into a struct of its own.
Also add the respective Allwinner A523 compatible string, and set bit 31
in its enable mask, to add support for this SoC.

The fix to atomically read the pipe head and tail state when not holding
the pipe mutex has caused a number of headaches due to the size change
of the involved types.
It turns out that we don't have _that_ many places that access these
fields directly and were affected, but we have more than we strictly
should have, because our low-level helper functions have been designed
to have intimate knowledge of how the pipes work.
And as a result, that random noise of direct 'pipe->head' and
'pipe->tail' accesses makes it harder to pinpoint any actual potential
problem spots remaining.
For example, we didn't have a "is the pipe full" helper function, but
instead had a "given these pipe buffer indexes and this pipe size, is
the pipe full". That's because some low-level pipe code does actually
want that much more complicated interface.
But most other places literally just want a "is the pipe full" helper,
and not having it meant that those places ended up being unnecessarily
much too aware of this all.
It would have been much better if only the very core pipe code that
cared had been the one aware of this all.
So let's fix it - better late than never. This just introduces the
trivial wrappers for "is this pipe full or empty" and to get how many
pipe buffers are used, so that instead of writing
if (pipe_full(pipe->head, pipe->tail, pipe->max_usage))
the places that literally just want to know if a pipe is full can just
say
if (pipe_is_full(pipe))
instead. The existing trivial cases were converted with a 'sed' script.
This cuts down on the places that access pipe->head and pipe->tail
directly outside of the pipe code (and core splice code) quite a lot.
The splice code in particular still revels in doing the direct low-level
accesses, and the fuse fuse_dev_splice_write() code also seems a bit
unnecessarily eager to go very low-level, but it's at least a bit better
than it used to be.

mlx5 misc enhancements 2025-03-04
This series introduces enhancements to the mlx5 core and Eth drivers.
Patches 1-3 by Shahar introduce support for configuring lanes alongside
speed when autonegotiation is disabled. The combination of speed and the
number of lanes corresponds to a specific link mode (in the extended
mask typically used in newer hardware), allowing the user to select a
precise link mode when autonegotiation is off, instead of just choosing
the speed.
Patch 4 by Amir extends the multi-port LAG support.

Existing match criteria didn't allow to match whole subnet and
only by specific addresses only. This caused to tunnel mode do not
forward such traffic through relevant SA.
In tunnel mode, policies look like this:
src 192.169.0.0/16 dst 192.169.0.0/16
dir out priority 383615 ptype main
tmpl src 192.169.101.2 dst 192.169.101.1
proto esp spi 0xc5141c18 reqid 1 mode tunnel
crypto offload parameters: dev eth2 mode packet
In this case, the XFRM core code handled all subnet calculations and
forwarded network address to the drivers e.g. 192.169.0.0.
For mlx5 devices, there is a need to set relevant prefix e.g. 0xFFFF00
to perform flow steering match operation.

Currently, when auto-negotiation is disabled, the driver retrieves
the speed and converts it into all link modes that correspond to
that speed. With this patch, we add the ability to set the number
of lanes, so that the combination of speed and lanes corresponds to
exactly one specific link mode for the extended bit map.
For the legacy bit map the driver sets all link modes correspond to
speed and lanes.
This change provides users with the option to set a specific link
mode, rather than enabling all link modes associated with a given
speed when auto-negotiation is off.

When doing "perf annotate", perf tool provides option to
use specific disassembler like llvm/objdump/capstone. The
order picked is to use llvm first and if that fails fallback
to objdump ie to use PERF_DISASM_LLVM, PERF_DISASM_CAPSTONE
and PERF_DISASM_OBJDUMP
In powerpc, when using "data type" sort keys, first preferred
approach is to read the raw instruction from the DSO. In objdump
is specified in "--objdump" option, it picks the symbol disassemble
using objdump. Currently disasm_line__parse_powerpc() function
uses length of the "line" to determine if objdump is used.
But there are few cases, where if objdump doesn't recognise the
instruction, the disassembled string will be empty.
Example:
134cdc: c4 05 82 41 beq 1352a0 <getcwd+0x6e0>
134ce0: ac 00 8e 40 bne cr3,134d8c <getcwd+0x1cc>
134ce4: 0f 00 10 04 pld r9,1028308
====>134ce8: d4 b0 20 e5
134cec: 16 00 40 39 li r10,22
134cf0: 48 01 21 ea ld r17,328(r1)
So depending on length of line will give bad results.
Add a new filed to annotation options structure,
"struct annotation_options" to save the disassembler used.
Use this info to determine if disassembly is done while
parsing the disasm line.

This naming enables exporting these flags to BPF clients, eliminating
the need to duplicate these flags in BPF code. Instead, BPF clients can
now access the same kernel-side values through CO:RE (Compile Once, Run

Currently, the calls to phylink's suspend and resume functions are
inside overly complex tests, and boil down to:
if (device_may_wakeup(priv->device) && priv->plat->pmt) {
call phylink
} else {
call phylink and
if (device_may_wakeup(priv->device))
do something else
}
This results in phylink always being called, possibly with differing
arguments for phylink_suspend().
Simplify this code, noting that each site is slightly different due to
the order in which phylink is called and the "something else".

If kzalloc in gred_init returns a NULL pointer, the code follows the
error handling path, invoking gred_destroy. This, in turn, calls
gred_offload, where memset could receive a NULL pointer as input,
potentially leading to a kernel crash.
When table->opt is NULL in gred_init(), gred_change_table_def()
is not called yet, so it is not necessary to call ->ndo_setup_tc()
in gred_offload().

stmmac_rx() declares a local variable named "buf_sz" but there is also
a global variable for a module parameter which is called the same. To
avoid confusion, rename the local variable.

The length of PERF_RECORD_KSYMBOL for BPF is a size of JITed code so
it'd be 0 when it's not JITed. The ksymbol is needed to symbolize the
code when it gets samples in the region but non-JITed code cannot get
samples. Thus it'd be ok to ignore them.
Actually it caused a performance issue in the perf tools on old ARM
kernels where it can refuse to JIT some BPF codes. It ended up
splitting the existing kernel map (kallsyms). And later lookup for a
kernel symbol would create a new kernel map from kallsyms and then
split it again and again. :(
Probably there's a bug in the kernel map/symbol handling in perf tools.
But I think we need to fix this anyway.

The own_cpus map variable may be non-NULL and hold a reference, in
particular on hybrid machines. Do a put before overwriting the
