AngeloGioacchino Del Regno is stepping in as co-maintainer for the
MediaTek SoC platform and starts by sending some dts fixes for
the mt8195 platform that had been pending for a while.
On the ixp4xx platform, Krzysztof Halasa steps down as co-maintainer,
reflecting that Linus Walleij has been handling this on his own
for the past few years.
Generic RISC-V kernels are now marked as incompatible with the
RZ/Five platform that requires custom hacks both for managing
its DMA bounce buffers and for addressing low virtual memory.
Finally, there is one bugfix for the AMDTEE firmware driver
to prevent a use-after-free bug.

Fei has reported that KASAN triggers during apply_alternatives() on
a 5-level paging machine:
BUG: KASAN: out-of-bounds in rcu_is_watching()
Read of size 4 at addr ff110003ee6419a0 by task swapper/0/0
...
__asan_load4()
rcu_is_watching()
trace_hardirqs_on()
text_poke_early()
apply_alternatives()
...
On machines with 5-level paging, cpu_feature_enabled(X86_FEATURE_LA57)
gets patched. It includes KASAN code, where KASAN_SHADOW_START depends on
__VIRTUAL_MASK_SHIFT, which is defined with cpu_feature_enabled().
KASAN gets confused when apply_alternatives() patches the
KASAN_SHADOW_START users. A test patch that makes KASAN_SHADOW_START
static, by replacing __VIRTUAL_MASK_SHIFT with 56, works around the issue.
Fix it for real by disabling KASAN while the kernel is patching alternatives.

The alternative stack checking in get_sigframe introduced by the Vector
support is not needed and has a problem. It is not needed as we have
already validate it at the beginning of the function if we are already
on an altstack. If not, the size of an altstack is always validated at
its allocation stage with sigaltstack_size_valid().
Besides, we must only regard the size of an altstack if the handler of a
signal is registered with SA_ONSTACK. So, blindly checking overflow of
an altstack if sas_ss_size not equals to zero will check against wrong
signal handlers if only a subset of signals are registered with
SA_ONSTACK.

Sergei Trofimovich reported a regression [0] caused by commit a0ade8404c
("af_packet: Fix warning of fortified memcpy() in packet_getname().").
It introduced a flex array sll_addr_flex in struct sockaddr_ll as a
union-ed member with sll_addr to work around the fortified memcpy() check.
However, a userspace program uses a struct that has struct sockaddr_ll in
the middle, where a flex array is illegal to exist.

When we're adding extents to the busy discard list, add them to the tail
of the list so that we get FIFO order. For FITRIM commands, this means
that we send discard bios sorted in order from longest to shortest, like
we did before commit 89cfa89960.
For transactions that are freeing extents, this puts them in the
transaction's busy list in FIFO order as well, which shouldn't make any
noticeable difference.

This makes the driver work with the new check in
v4l2_async_register_subdev() that was introduced recently in 6.6-rc1.
Without this change, probe fails with:

ov8858 1-0036: sub-device fwnode is an endpoint!
ov8858 1-0036: v4l2 async register subdev failed

In ipu_bridge_get_ivsc_acpi_dev(), the "ivsc_adev" acpi_device pointer
from the outer loop is handed over to the caller, which takes proper
care of its reference count.
However, the "consumer" acpi_device pointer from the inner loop is lost,
without decrementing its reference count.
Fix this by adding the missing call to acpi_dev_put().

The big V4L2 async framework overhaul simplified linked lists used by the

of those drivers rely on searching for entities in both async notifier's
waiting and done lists. Do that by separately traversing both.

Since the stream API is still experimental it is currently locked away
behind the internal, default disabled, v4l2_subdev_enable_streams_api flag.
Advertising V4L2_SUBDEV_CAP_STREAMS when the streams API is disabled
confuses userspace. E.g. it causes the following libcamera error:
ERROR SimplePipeline simple.cpp:1497 Failed to reset routes for
/dev/v4l-subdev1: Inappropriate ioctl for device
Don't report V4L2_SUBDEV_CAP_STREAMS when the streams API is disabled
to avoid problems like this.

Provide common prototypes for arch_register_cpu() and
arch_unregister_cpu(). These are called by acpi_processor.c, with weak
versions, so the prototype for this is already set. It is generally not
necessary for function prototypes to be conditional on preprocessor macros.
Some architectures (e.g. Loongarch) are missing the prototype for this, and
rather than add it to Loongarch's asm/cpu.h, do the job once for everyone.
Since this covers everyone, remove the now unnecessary prototypes in
asm/cpu.h, and therefore remove the 'static' from one of ia64's
arch_register_cpu() definitions.

On some OEM systems, adding a W7900 dGPU triggers RAS errors and hangs
at a black screen on startup. This issue occurs only if `ucsi_acpi` has
loaded before `amdgpu` has loaded. The reason for this failure is that
`amdgpu` uses power_supply_is_system_supplied() to determine if running
on AC or DC power at startup. If this value is reported incorrectly the
dGPU will also be programmed incorrectly and trigger errors.
power_supply_is_system_supplied() reports the wrong value because UCSI
power supplies provided as part of the system don't properly report the
scope as "DEVICE" scope (not powering the system).
In order to fix this issue check the capabilities reported from the UCSI
power supply to ensure that it supports charging a battery and that it can
be powered by AC. Mark the scope accordingly.

The hpd signal is not updated despite being part of the status, so the
