GPLL0_OUT_DIV (.fw_name = "gcc_disp_gpll0_div_clk_src") was previously
made to reuse the same parent enum entry as GPLL0_OUT_MAIN

Resolve it by introducing its own entry in the parent enum and

Networking resets in IPQ6018 all use bitmask as they require multiple

So, current networking resets have the same register and bit 0 set which

[ Upstream commit 4a52108936 ]
This patch adds the support for giving the complete bitmask
in reset structure and reset operation will use this bitmask
for all reset operations.
Currently, reset structure only takes a single bit for each reset
and then calculates the bitmask by using the BIT() macro.
However, this is not sufficient anymore for newer SoC-s like IPQ8074,
IPQ6018 and more, since their networking resets require multiple bits
to be asserted in order to properly reset the HW block completely.
So, in order to allow asserting multiple bits add "bitmask" field to
qcom_reset_map, and then use that bitmask value if its populated in the
driver, if its not populated, then we just default to existing behaviour
and calculate the bitmask on the fly.

VIDIOC_ENUMINPUT documentation describes the tuner field of
struct v4l2_input as index:
Documentation/userspace-api/media/v4l/vidioc-enuminput.rst
"
* - __u32
- ``tuner``
- Capture devices can have zero or more tuners (RF demodulators).
When the ``type`` is set to ``V4L2_INPUT_TYPE_TUNER`` this is an
RF connector and this field identifies the tuner. It corresponds
to struct :c:type:`v4l2_tuner` field ``index``. For
details on tuners see :ref:`tuner`.
"
Drivers I could find also use the 'tuner' field as an index, e.g.:
drivers/media/pci/bt8xx/bttv-driver.c bttv_enum_input()
drivers/media/usb/go7007/go7007-v4l2.c vidioc_enum_input()
However, the UAPI comment claims this field is 'enum v4l2_tuner_type':
include/uapi/linux/videodev2.h
This field being 'enum v4l2_tuner_type' is unlikely as it seems to be
never used that way in drivers, and documentation confirms it. It seem
this comment got in accidentally in the commit which this patch fixes.
Fix the UAPI comment to stop confusion.

Returning an error value in a platform driver's remove callback results in
a generic error message being emitted by the driver core, but otherwise it
doesn't make a difference. The device goes away anyhow.
For each case where ret is non-zero the driver already emits an error
message, so suppress the generic error message by returning zero
unconditionally. (Side note: The return value handling was unreliable
anyhow as the value returned by dwc2_exit_hibernation() was overwritten
anyhow if hsotg->in_ppd was non-zero.)

commit b90ecc0379 upstream.
Currently, associating a loop device with a different file descriptor
does not increment its diskseq. This allows the following race
condition:
1. Program X opens a loop device
2. Program X gets the diskseq of the loop device.
3. Program X associates a file with the loop device.
4. Program X passes the loop device major, minor, and diskseq to
something.
5. Program X exits.
6. Program Y detaches the file from the loop device.
7. Program Y attaches a different file to the loop device.
8. The opener finally gets around to opening the loop device and checks
that the diskseq is what it expects it to be. Even though the
diskseq is the expected value, the result is that the opener is
accessing the wrong file.
From discussions with Christoph Hellwig, it appears that
disk_force_media_change() was supposed to call inc_diskseq(), but in
fact it does not. Adding a Fixes: tag to indicate this. Christoph's
Reported-by is because he stated that disk_force_media_change()
calls inc_diskseq(), which is what led me to discover that it should but
does not.

commit 95a55437dc upstream.
The Amiga partition parser module uses signed int for partition sector
address and count, which will overflow for disks larger than 1 TB.
Use u64 as type for sector address and size to allow using disks up to
2 TB without LBD support, and disks larger than 2 TB with LBD. The RBD
format allows to specify disk sizes up to 2^128 bytes (though native
OS limitations reduce this somewhat, to max 2^68 bytes), so check for
u64 overflow carefully to protect against overflowing sector_t.
This bug was reported originally in 2012, and the fix was created by
the RDB author, Joanne Dow <jdow@earthlink.net>. A patch had been
discussed and reviewed on linux-m68k at that time but never officially
submitted (now resubmitted as patch 1 of this series).
Patch 3 (this series) adds additional error checking and warning
messages. One of the error checks now makes use of the previously
unused rdb_CylBlocks field, which causes a 'sparse' warning
(cast to restricted __be32).
Annotate all 32 bit fields in affs_hardblocks.h as __be32, as the
on-disk format of RDB and partition blocks is always big endian.

commit bd55842ed9 upstream.
The PCM memory allocation helpers have a sanity check against too many
buffer allocations. However, the check is performed without a proper
lock and the allocation isn't serialized; this allows user to allocate
more memories than predefined max size.
Practically seen, this isn't really a big problem, as it's more or
less some "soft limit" as a sanity check, and it's not possible to
allocate unlimitedly. But it's still better to address this for more
consistent behavior.
The patch covers the size check in do_alloc_pages() with the
card->memory_mutex, and increases the allocated size there for
preventing the further overflow. When the actual allocation fails,
the size is decreased accordingly.

commit 89dbb335cb upstream.
snd_jack_report() is supposed to be callable from an IRQ context, too,
and it's indeed used in that way from virtsnd driver. The fix for
input_dev race in commit 1b6a6fc528 ("ALSA: jack: Access input_dev
under mutex"), however, introduced a mutex lock in snd_jack_report(),
and this resulted in a potential sleep-in-atomic.
For addressing that problem, this patch changes the relevant code to
use the object get/put and removes the mutex usage. That is,
snd_jack_report(), it takes input_get_device() and leaves with
input_put_device() for assuring the input_dev being assigned.
Although the whole mutex could be reduced, we keep it because it can
be still a protection for potential races between creation and
deletion.

commit c0aabed9ca upstream.
In scenarios where pullup relies on resume (get sync) to initialize
the controller and set the run stop bit, then core_init is followed by
gadget_resume which will eventually set run stop bit.
But in cases where the core_init fails, the return value is not sent
back to udc appropriately. So according to UDC the controller has
started but in reality we never set the run stop bit.
On systems like Android, there are uevents sent to HAL depending on
whether the configfs_bind / configfs_disconnect were invoked. In the
above mentioned scnenario, if the core init fails, the run stop won't
be set and the cable plug-out won't result in generation of any
disconnect event and userspace would never get any uevent regarding
cable plug out and we never call pullup(0) again. Furthermore none of
the next Plug-In/Plug-Out's would be known to configfs.
Return back the appropriate result to UDC to let the userspace/
configfs know that the pullup failed so they can take appropriate
action.

[ Upstream commit 0303c9729a ]
Niklāvs reported a boot regression on an Alderlake machine and bisected it
to commit 9df9d2f047 ("init: Invoke arch_cpu_finalize_init() earlier").
By moving the invocation of arch_cpu_finalize_init() further down he
identified that efi_enter_virtual_mode() is the function which causes the
boot hang.
The main difference of the earlier invocation is that the boot CPU is
already fully initialized and mitigations and alternatives are applied.
But the only really interesting change turned out to be IBT, which is now
enabled before efi_enter_virtual_mode(). "ibt=off" on the kernel command
line cured the problem.
Inspection of the involved calls in efi_enter_virtual_mode() unearthed that
efi_set_virtual_address_map() is the only place in the kernel which invokes
an EFI call without the IBT safe wrapper. This went obviously unnoticed so
far as IBT was enabled later.
Use arch_efi_call_virt() instead of efi_call() to cure that.

[ Upstream commit 893b24181b ]
The FFR is a predicate register which can vary between 16 and 256 bits
in size depending upon the configured vector length. When saving the
SVE state in streaming SVE mode, the FFR register is inaccessible and
so commit 9f58486657 ("arm64/sve: Make access to FFR optional") simply
clears the FFR field of the in-memory context structure. Unfortunately,
it achieves this using an unconditional 8-byte store and so if the SME
vector length is anything other than 64 bytes in size we will either
fail to clear the entire field or, worse, we will corrupt memory
immediately following the structure. This has led to intermittent kfence
splats in CI [1] and can trigger kmalloc Redzone corruption messages
when running the 'fp-stress' kselftest:
| =============================================================================
| BUG kmalloc-1k (Not tainted): kmalloc Redzone overwritten

Replace the 8-byte store with a store of a predicate register which has
been zero-initialised with PFALSE, ensuring that the entire field is
cleared in memory.
