Currently <linux/i2c.h> includes <linux/mod_devicetable.h> transitively

The subsystem private header i2c-core.h uses several symbols defined in
<linux/i2c.h>, e.g. struct i2c_board_info and i2c_lock_bus()). This
doesn't pose a problem in practise because all files including
"i2c-core.h" also include <linux/i2c.h>.
To make this more robust add an include statement for <linux/i2c.h>
making the header self-contained.

<linux/of_platform.h> uses resource_size_t and relies on the transitive
include <linux/mod_devicetable.h> -> <linux/types.h>. It also uses error
constants and thus relying on the include chain
<linux/mod_devicetable.h> -> <linux/uuid.h> -> <linux/string.h> ->

With the plan to split <linux/mod_devicetable.h> per subsystem and then
only letting of_platform.h include the of-specific bits (which don't
require these two headers), add the needed includes explicitly to keep

Platform drivers can define an array containing the supported device
variants to be assigned to the struct platform_driver's .id_table.
While a forward declaration of struct platform_device_id is technically
enough to make the driver self-contained, it's reasonable to provide the
(very lightweight) data type definition for that array in
<linux/platform_device.h> to not add that burden to all platform drivers
with an id-table.
Note that currently <linux/device.h> transitively includes
<linux/mod_devicetable.h> that provides struct platform_device_id. But
that include is planned to be replaced by a tighter set of includes that
only define the structures relevant for the stuff in <linux/device.h>.

<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:
$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038
The result is that even when touching an obscure device id struct most
of the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per subsystem
headers and only including what is really needed reduces the amount of
needed recompilation.
Implement the first step and define each device id struct in a separate
header (together with its associated #defines).
<linux/mod_devicetable.h> is modified to include all the new headers to
continue to provide the same symbols.
Several headers currently include <linux/mod_devicetable.h>, those that
are most lukrative to include only their subsystem headers only are:
$ git -C source grep -l mod_devicetable.h include/linux | while read h; do echo -n "$h:"; find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l $h | wc -l; done | sort -t: -k2 -n -r | head

struct cpu_feature isn't really a device_id struct. That is kept in

The function ata_scsi_rbuf_fill() is used to copy the response of
emulated SCSI commands from ata_scsi_rbuf to the SCSI command's
scatterlist.
Currently, sg_copy_from_buffer() is called with the size argument
set to ATA_SCSI_RBUF_SIZE (2048 bytes). Since ata_scsi_rbuf is
zeroed out before the simulation actor is invoked, copying the
full buffer size causes the remainder of the SCSI command's
transfer buffer (beyond the actual response length 'len') to be
overwritten with zeroes. This clobbers any pre-existing sentinel
values or data in the caller's buffer tail, even though the
correct residual count is reported via scsi_set_resid().
Fix this by passing the actual response length 'len' as the copy
size to sg_copy_from_buffer(), ensuring that the tail of the
caller's buffer remains untouched. Also, add a defensive check
to ensure that the actor does not return a length exceeding the
static buffer capacity. If this occurs, trigger a WARN_ON(),
fail the command with an aborted command error, and return
immediately without copying any data.
The fix was tested by invoking an SCSI SG_IO INQUIRY on
an ATA disk on vanilla build, and build with the fix. Confirmed
that the input buffer's tail end remains unmodified with the fix.

gemini_sata_probe() returns directly and skips the existing

ata_dev_config_cpr() takes the number of range descriptors from buf[0]
of the concurrent positioning ranges log (up to 255), which the device
reports independently of the log size in the GPL directory. The count is
then walked at a fixed 32-byte stride in two places with no bound: the
log read here, and the INQUIRY VPD page B9h emitter, which writes one
descriptor per range into the fixed 2048-byte ata_scsi_rbuf. A device
reporting a count larger than its own log overflows the read buffer (up
to 7704 bytes past a 512-byte slab), and a count above 62 overflows the
response buffer on the emit side.
Bound the count once, on probe, against both the log the device returned
and the number of descriptors the VPD B9h response buffer can hold
(ATA_DEV_MAX_CPR, derived from the rbuf size). Reject an out-of-range
count with a warning; this keeps the emitter in bounds with no separate
change there.

The commit cited below should not have been merged. It attemted to fix an
existing problem ansd thereby introduced new problems by keeping the
pi_state in state Q_REQUEUE_PI_IN_PROGRESS and leaking it.
Based on the commit description the intention was to handle the case
when task_blocks_on_rt_mutex() returns -EDEADLK and the following
remove_waiter() dereferences the NULL pointer in waiter->task.
That is already handled by Davidlohr in commit 40a25d59e8
("locking/rtmutex: Skip remove_waiter() when waiter is not enqueued") and
requires no further acting.
Revert the commit breaking the "waiter == owner" case again.
Fixes: 74e144274a ("futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock")

The default msi-map from sm8550.dtsi is deleted for both pcie0 and
pcie1. The QPS615 PCIe switch on each port exposes more than two
devices (1 USP + 3 DSPs), but Gunyah currently limits ITS device
mappings to two per root complex to save memory. With msi-map
present, the ITS MAPD command times out.
Deleting msi-map causes the DWC controller to fall back to its
internal iMSI-RX module, which handles MSIs without this limitation.

Enable secondary USB controller in host mode on lemans EVK Platform.
Secondary USB controller is connected to a Genesys Logic USB HUB GL3590
having 4 ports. The ports of hub that are present on lemans EVK standalone
board are used as follows:-
1) port-1 is connected to HD3SS3220 Type-C port controller.
2) port-4 is used for the M.2 E key on corekit. Standard core kit uses UART
for Bluetooth. This port is to be used only if user optionally replaces the
WiFi card with the NFA765 chip which uses USB for Bluetooth.
Remaining 2 ports will become functional when the interface plus mezzanine
board is stacked on top of corekit:
3) port-2 is connected to another hub which is present on the mezz through
which 4 type-A ports are connected.
4) port-3 is used for the M.2 B key for a 5G card when the mezz is
connected.

MAINTAINERS: Add a mailing list entry to MFD
When data buffers are reused, e.g. for interval sample records, the
first record determines the data length, and the size of the buffer for
user copy. Current monwriter code does not check if the data length was
changed for subsequent records, which also would never happen for valid
user programs.
However, a malicious user could change the data length, resulting in out
of bounds user copy to the kernel buffer, and memory corruption. By
default, the monwriter misc device is created with root-only permissions,
so practical impact is typically low.
Fix this by checking for changed data length and rejecting such records.

changing related callers to pass proper mm_struct pointer.
