Linux defaults to picking the non-working ACPI video backlight interface
on the Apple iMac12,1 and iMac12,2.
Add a DMI quirk to pick the working native radeon_bl0 interface instead.

Screen brightness can only be changed once on HP ZBook Fury 16 G10.
The vendor reports that the issue is related to the fact that Linux doesn't
invoke _PS0 at boot for all ACPI devices, as expected by the platform firmware:
Scope (\_SB.PC00.GFX0)
{
Scope (DD1F)
{
Method (_PS0, 0, Serialized) // _PS0: Power State 0
{
If (CondRefOf (\_SB.PC00.LPCB.EC0.SSBC))
{
\_SB.PC00.LPCB.EC0.SSBC ()
}
}
...
}
...
}
The \_SB.PC00.GFX0.DD1F is the panel device, and its _PS0 needs to be
executed at the initialization time to make the brightness control work
properly.
_PS0 is not evaluated for this device, because _PSC is missing,
which violates the ACPI specification (ACPI 6.5, section 7.3.6).
Commit b3785492268f ("ACPI / PM: Do not power manage devices in unknown
initial states") tried to work around missing _PSC on platforms with
defective firmware, but got reverted due to a regression.
So the safest approach is to use acpi_device_fix_up_power_extended() to
put ACPI video and its child devices to D0 to address the issue at hand.

With ACPI Spec 6.5 chapter 5.2.12.20, each processor in LoongArch
systems has a Core Programmable Interrupt Controller in MADT. The
value of its type is 0x11 in the spec and defined as enum variable
ACPI_MADT_TYPE_CORE_PIC in the Linux kernel.
Physical IDs can be retrieved from MADT for LoongArch systems during
initialization and they can be retrieved from the _MAT output for
hotplug CPUs.
Add physical CPU ID enumeration for LoongArch systems.

Inside IVSC, switching ownership requires an interface with two
different hardware modules, ACE and CSI. The software interface
to these modules is based on Intel MEI framework. Usually mei
client devices are dynamically created, so the info of consumers
depending on mei client devices is not present in the firmware
tables.
This causes problems with the probe ordering with respect to
drivers for consumers of these MEI client devices. But on these
camera sensor devices, the ACPI nodes describing the sensors all
have a _DEP dependency on the matching MEI bus ACPI device, so
adding IVSC MEI bus ACPI device to acpi_honor_dep_ids allows
solving the probe-ordering problem by deferring the enumeration of
ACPI-devices which have a _DEP dependency on an IVSC mei bus ACPI
device.
On TGL platform, the HID of IVSC MEI bus ACPI device is INTC1059,
and on ADL platform, the HID is INTC1095. So add both of them to
acpi_honor_dep_ids.

Since for MMIO driver using FIFO registers, also known as tpm_tis, the
default (and tbh recommended) behaviour is now the polling mode, the
"tristate" workaround is no longer for benefit.
If someone wants to explicitly enable IRQs for a TPM chip that should be
without question allowed. It could very well be a piece hardware in the
existing deny list because of e.g. firmware update or something similar.
While at it, document the module parameter, as this was not done in 2006
when it first appeared in the mainline.

The following warning is reported when frame pointers and kernel IBT are
enabled:
vmlinux.o: warning: objtool: ibt_selftest+0x11: sibling call from callable instruction with modified stack frame
The problem is that objtool interprets the indirect branch in
ibt_selftest() as a sibling call, and GCC inserts a (partial) frame
pointer prologue before it:
0000 000000000003f550 <ibt_selftest>:
0000 3f550: f3 0f 1e fa endbr64
0004 3f554: e8 00 00 00 00 call 3f559 <ibt_selftest+0x9> 3f555: R_X86_64_PLT32 __fentry__-0x4

0011 3f561: ff e0 jmp *%rax
Note the inline asm is missing ASM_CALL_CONSTRAINT, so the 'push %rbp'
happens before the indirect branch and the 'mov %rsp, %rbp' happens
afterwards.
Simplify the generated code and make it easier to understand for both
tools and humans by moving the selftest to proper asm.

Mike and others noticed that EEVDF does like to over-schedule quite a
bit -- which does hurt performance of a number of benchmarks /
workloads.
In particular, what seems to cause over-scheduling is that when lag is
of the same order (or larger) than the request / slice then placement
will not only cause the task to be placed left of current, but also
with a smaller deadline than current, which causes immediate
preemption.
[ notably, lag bounds are relative to HZ ]
Mike suggested we stick to picking 'current' for as long as it's
eligible to run, giving it uninterrupted runtime until it reaches
parity with the pack.
Augment Mike's suggestion by only allowing it to exhaust it's initial
request.
One random data point:
echo NO_RUN_TO_PARITY > /debug/sched/features

The RT5640 driver is already using GPIO descriptors for some
stuff, all that is needed is to convert the remaining LDO1
control line to also use descriptors.
Simplify the code using gpiod_get_optional() and drop the
special "of" parsing function: these descriptors need not
come from device tree and it's optional so hey.
Keep some NULL checks around the GPIO operations even though
gpiolib is essentially NULL-tolerant, because by checking
for whether we have a valid GPIO descriptor or not we can
avoid a 400 ms delay which is great.

Pausing and canceling balance can race to interrupt balance lead to BUG_ON
panic in btrfs_cancel_balance. The BUG_ON condition in btrfs_cancel_balance

However, the race condition has no other side effects. We can fix that.

bio_ctrl->len_to_oe_boundary is used to make sure we stay inside a zone
as we submit bios for writes. Every time we add a page to the bio, we
decrement those bytes from len_to_oe_boundary, and then we submit the
bio if we happen to hit zero.
Most of the time, len_to_oe_boundary gets set to U32_MAX.
submit_extent_page() adds pages into our bio, and the size of the bio
ends up limited by:
- Are we contiguous on disk?
- Does bio_add_page() allow us to stuff more in?
- is len_to_oe_boundary > 0?
The len_to_oe_boundary math starts with U32_MAX, which isn't page or
sector aligned, and subtracts from it until it hits zero. In the
non-zoned case, the last IO we submit before we hit zero is going to be
unaligned, triggering BUGs.
This is hard to trigger because bio_add_page() isn't going to make a bio
of U32_MAX size unless you give it a perfect set of pages and fully
contiguous extents on disk. We can hit it pretty reliably while making
large swapfiles during provisioning because the machine is freshly
booted, mostly idle, and the disk is freshly formatted. It's also
possible to trigger with reads when read_ahead_kb is set to 4GB.
The code has been clean up and shifted around a few times, but this flaw
has been lurking since the counter was added. I think the commit
24e6c8082208 ("btrfs: simplify main loop in submit_extent_page") ended
up exposing the bug.
The fix used here is to skip doing math on len_to_oe_boundary unless
we've changed it from the default U32_MAX value. bio_add_page() is the
real limit we want, and there's no reason to do extra math when block
layer is doing it for us.
Sample reproducer, note you'll need to change the path to the bdi and
device:
SUBVOL=/btrfs/swapvol
SWAPFILE=$SUBVOL/swapfile
SZMB=8192
mkfs.btrfs -f /dev/vdb

To fix this, use fs_devices::metadata_uuid. We copy fsid into

Commit 'fa6999e326fe ("s390/pkey: support CCA and EP11 secure ECC
private keys")' introduced PKEY_TYPE_EP11_AES for the PKEY_GENSECK2
IOCTL, to enable userspace to generate securekey blobs of this
type. Unfortunately, all PKEY_GENSECK2 IOCTL requests for
PKEY_TYPE_EP11_AES return with an error (-EINVAL). Fix the handling
for PKEY_TYPE_EP11_AES in PKEY_GENSECK2 IOCTL, so that userspace can
generate securekey blobs of this type.
The start of the header and the keyblob, as well as the length need
special handling, depending on the internal keyversion. Add a helper
function that splits an uninitialized buffer into start and size of
the header as well as start and size of the payload, depending on the
requested keyversion.
Do the header-related calculations and the raw genkey request handling
in separate functions. Use the raw genkey request function for
internal purposes.

Commit 'fa6999e326fe ("s390/pkey: support CCA and EP11 secure ECC
private keys")' introduced PKEY_TYPE_EP11_AES as a supplement to
PKEY_TYPE_EP11. All pkeys have an internal header/payload structure,
which is opaque to the userspace. The header structures for
PKEY_TYPE_EP11 and PKEY_TYPE_EP11_AES are nearly identical and there
is no reason, why different structures are used. In preparation to fix
the keyversion handling in the broken PKEY IOCTLs, the same header
structure is used for PKEY_TYPE_EP11 and PKEY_TYPE_EP11_AES. This
reduces the number of different code paths and increases the
readability.

loongarch"
Unifying the asm-generic headers across 32-bit and 64-bit architectures
based on the compiler provided macros was a good idea and appears to work
with all user space, but it caused a regression when building old kernels
on systems that have the new headers installed in /usr/include, as this
combination trips an inconsistency in the kernel's own tools/include
headers that are a mix of userspace and kernel-internal headers.
This affects kernel builds on arm64, riscv64 and loongarch64 systems that
might end up using the "#define __BITS_PER_LONG 32" default from the old
tools headers. Backporting the commit into stable kernels would address
this, but it would still break building kernels without that backport,
and waste time for developers trying to understand the problem.
arm64 build machines are rather common, and on riscv64 this can also
happen in practice, but loongarch64 is probably new enough to not
be used much for building old kernels, so only revert the bits
for arm64 and riscv.

Qualcomm ARM64 fixes for v6.5
This corrects the invalid path specifier for L3 interconnects in the CPU
nodes of SM8150 and SM8250. It corrects the compatible of the SC8180X L3
node, to pass the binding check.
The crypto core, and its DMA controller, is disabled on SM8350 to avoid
the system from crashing at boot while the issue is diagnosed.
A thermal zone node name conflict is resolved for PM8150L, on the RB5
board.
The UFS vccq voltage is corrected on the SA877P Ride platform, to
address observed stability issues.
The reg-names of the DSI phy on SC7180 are restored after an accidental
search-and-replace update.

Use a device property "cirrus,firmware-uid" to get the unique firmware
identifier instead of using ACPI _SUB. There aren't any products that use
_SUB.
There will not usually be a _SUB in Soundwire nodes. The ACPI can use a
_DSD section for custom properties.
There is also a need to support instantiating this driver using software
nodes. This is for systems where the CS35L56 is a back-end device and the
ACPI refers only to the front-end audio device - there will not be any ACPI
references to CS35L56.

This reverts commit ca62297b2085b5b3168bd891ca24862242c635a1.
Commit ca62297b2085 ("drm/edid: Fix csync detailed mode parsing") fixed
EDID detailed mode sync parsing. Unfortunately, there are quite a few
displays out there that have bogus (zero) sync field that are broken by
the change. Zero means analog composite sync, which is not right for
digital displays, and the modes get rejected. Regardless, it used to
work, and it needs to continue to work. Revert the change.
Rejecting modes with analog composite sync was the part that fixed the
gitlab issue 8146 [1]. We'll need to get back to the drawing board with
that.

Christian reported spurious module load crashes after some of Song's
module memory layout patches.
Turns out that if the very last instruction on the very last page of the
module is a 'JMP __x86_return_thunk' then __static_call_fixup() will
trip a fault and die.
And while the module rework made this slightly more likely to happen,
it's always been possible.
