After some digging around I have found that this laptop has Cirrus's smart
aplifiers connected to SPI bus (spi1-CSC3551:00-cs35l41-hda).
To get them correctly detected and working I had to modify patch_realtek.c
with ASUS EXPERTBOOK P5405CSA 1.0 SystemID (0x1043, 0x1f63) and add
corresponding hda_quirk (ALC245_FIXUP_CS35L41_SPI_2).

[ Upstream commit 011ea742a25a77bac3d995f457886a67d178c6f0 ]
If a data sector on an OFS floppy contains a value > 0x1e8 (the
largest amount of data that fits in the sector after its header), then
an Amiga reading the file can return corrupt data, by taking the
overlarge size at its word and reading past the end of the buffer it
read the disk sector into!
The cause: when affs_write_end_ofs() writes data to an OFS filesystem,
the new size field for a data block was computed by adding the amount
of data currently being written (into the block) to the existing value
of the size field. This is correct if you're extending the file at the
end, but if you seek backwards in the file and overwrite _existing_
data, it can lead to the size field being larger than the maximum
legal value.
This commit changes the calculation so that it sets the size field to
the max of its previous size and the position within the block that we
just wrote up to.

If I write a file to an OFS floppy image, and try to read it back on
an emulated Amiga running Workbench 1.3, the Amiga reports a disk
error trying to read the file. (That is, it's unable to read it _at
all_, even to copy it to the NIL: device. It isn't a matter of getting
the wrong data and being unable to parse the file format.)
This is because the 'sequence number' field in the OFS data block
header is supposed to be based at 1, but affs writes it based at 0.
All three locations changed by this patch were setting the sequence
number to a variable 'bidx' which was previously obtained by dividing
a file position by bsize, so bidx will naturally use 0 for the first
block. Therefore all three should add 1 to that value before writing
it into the sequence number field.
With this change, the Amiga successfully reads the file.

The firmware dumps can be pretty big, and since we use single
pages for each SG table entry, even the table itself may end
up being an order-5 allocation. Build chained tables so that
we need not allocate a higher-order table here.
This could be improved and cleaned up, e.g. by using the SG
pool code or simply kvmalloc(), but all of that would require
also updating the devcoredump first since that frees it all,
so we need to be more careful. SG pool might also run against
the CONFIG_ARCH_NO_SG_CHAIN limitation, which is irrelevant
here.
Also use _devcd_free_sgtable() for the error paths now, much
simpler especially since it's in two places now.

Prior to commit 496121c021 ("ACPI: processor: idle: Allow probing on
platforms with one ACPI C-state"), the acpi_idle driver wouldn't load on
systems without a valid C-State at least as deep as C2.
The behavior was desirable for guests on hypervisors such as VMWare
ESXi, which by default don't have the _CST ACPI method, and set the C2
and C3 latencies to 101 and 1001 microseconds respectively via the FADT,
to signify they're unsupported.
Since the above change though, these virtualized deployments end up
loading acpi_idle, and thus entering the default C1 C-State set by
acpi_processor_get_power_info_default(); this is undesirable for a
system that's communicating to the OS it doesn't want C-States (missing
_CST, and invalid C2/C3 in FADT).
Make acpi_processor_get_power_info_fadt() return -ENODEV in that case,
so that acpi_processor_get_cstate_info() exits early and doesn't set
pr->flags.power = 1.

The pyrf_event__new() method copies the event obtained from the perf

for further consumption, so it copies perf_event.header.size bytes to

struct pyrf_event {

struct evsel * evsel; /* 16 8 */
struct perf_sample sample; /* 24 312 */
/* XXX last struct has 7 bytes of padding, 2 holes */
/* --- cacheline 5 boundary (320 bytes) was 16 bytes ago --- */
union perf_event event; /* 336 4168 */

/* member types with holes: 1, total: 2 */
/* paddings: 1, sum paddings: 7 */
/* last cacheline: 24 bytes */
};
$
It was doing so without checking if the event just obtained has more
than that space, fix it.
This isn't a proper, final solution, as we need to support larger

When processing tracepoints the perf python binding was parsing the
event before calling perf_mmap__consume(&md->core) in
pyrf_evlist__read_on_cpu().
But part of this event parsing was to set the perf_sample->raw_data
pointer to the payload of the event, which then could be overwritten by
other event before tracepoint fields were asked for via event.prev_comm
in a python program, for instance.
This also happened with other fields, but strings were were problems
were surfacing, as there is UTF-8 validation for the potentially garbled
data.
This ended up showing up as (with some added debugging messages):

When event.next_comm was asked for, the PyUnicode_FromString() python
API would fail and that tracepoint field wouldn't be available, stopping
the tools/perf/python/tracepoint.py test tool.
But, since we already do a copy of the whole event in pyrf_event__new,
just use it and while at it remove what was done in in e8968e6541
("perf python: Fix pyrf_evlist__read_on_cpu event consuming") because we
don't really need to wait for parsing the sample before declaring the
event as consumed.
This copy is questionable as is now, as it limits the maximum event +
sample_type and tracepoint payload to sizeof(union perf_event), this all
has been "working" because 'struct perf_event_mmap2', the largest entry
in 'union perf_event' is:

Patch series "powerpc/crash: use generic crashkernel reservation", v3.
Commit 0ab97169aa05 ("crash_core: add generic function to do reservation")
added a generic function to reserve crashkernel memory. So let's use the
same function on powerpc and remove the architecture-specific code that
essentially does the same thing.
The generic crashkernel reservation also provides a way to split the
crashkernel reservation into high and low memory reservations, which can
be enabled for powerpc in the future.
Additionally move powerpc to use generic APIs to locate memory hole for
kexec segments while loading kdump kernel.
This patch (of 7):
kexec_elf_load() loads an ELF executable and sets the address of the
lowest PT_LOAD section to the address held by the lowest_load_addr
function argument.
To determine the lowest PT_LOAD address, a local variable lowest_addr
(type unsigned long) is initialized to UINT_MAX. After loading each
PT_LOAD, its address is compared to lowest_addr. If a loaded PT_LOAD
address is lower, lowest_addr is updated. However, setting lowest_addr to
UINT_MAX won't work when the kernel image is loaded above 4G, as the
returned lowest PT_LOAD address would be invalid. This is resolved by
initializing lowest_addr to ULONG_MAX instead.
This issue was discovered while implementing crashkernel high/low
reservation on the PowerPC architecture.

Checking the binary representation of two structs (of the same type)
for equality doesn't have the same semantic as comparing all members for
equality. The former might find a difference where the latter doesn't in
the presence of padding or when ambiguous types like float or bool are
involved. (Floats typically have different representations for single
values, like -0.0 vs +0.0, or 0.5 * 2² vs 0.25 * 2³. The type bool has
at least 8 bits and the raw values 1 and 2 (probably) both evaluate to
true, but memcmp finds a difference.)
When searching for a channel that already has the configuration we need,
the comparison by member is the one that is needed.
Convert the comparison accordingly to compare the members one after
another. Also add a static_assert guard to (somewhat) ensure that when
struct ad7124_channel_config::config_props is expanded, the comparison
is adapted, too.
This issue is somewhat theoretic, but using memcmp() on a struct is a
bad pattern that is worth fixing.

[ Upstream commit 55741c723318905e6d5161bf1e12749020b161e3 ]
The ffs() function returns the index of the first set bit, starting from 1.
If no bits are set, it returns zero. This behavior causes an off-by-one
page size in the debug message, as the page size calculation [1]
is zero-based, while ffs() is one-based.
Fix this by subtracting one from the result of ffs(). Note that since
variable 'val' is unsigned, subtracting one from zero will result in the
maximum unsigned integer value. Consequently, the condition 'if (val < 16)'
will still function correctly.
[1], Page size: (2^(n+12)), where 'n' is the set page size bit.

If a match was not found, then the write_raw() callback would return
the odr index, not an error. Return -EINVAL if this occurs.
To avoid similar issues in future, introduce j, a new indexing variable
rather than using ret for this purpose.

As recommended by section 4.3.7 ("Synchronization when using system
instructions to progrom the trace unit") of ARM IHI 0064H.b, the
self-hosted trace analyzer must perform a Context synchronization

Additionally, add an ISB between the each read of TRCSTATR on
coresight_timeout() when using system instructions to program the
trace unit.
