Patch series "vma_start_write_killable"", v2.
When we added the VMA lock, we made a major oversight in not adding a
killable variant. That can run us into trouble where a thread takes the
VMA lock for read (eg handling a page fault) and then goes out to lunch
for an hour (eg doing reclaim). Another thread tries to modify the VMA,
taking the mmap_lock for write, then attempts to lock the VMA for write.
That blocks on the first thread, and ensures that every other page fault
now tries to take the mmap_lock for read. Because everything's in an
uninterruptible sleep, we can't kill the task, which makes me angry.
This patchset just adds vma_start_write_killable() and converts one caller
to use it. Most users are somewhat tricky to convert, so expect follow-up
individual patches per call-site which need careful analysis to make sure
we've done proper cleanup.
This patch (of 2):
The vma can be held read-locked for a substantial period of time, eg if
memory allocation needs to go into reclaim. It's useful to be able to
send fatal signals to threads which are waiting for the write lock.

Patch series "introduce VM_MAYBE_GUARD and make it sticky", v4.
Currently, guard regions are not visible to users except through
/proc/$pid/pagemap, with no explicit visibility at the VMA level.
This makes the feature less useful, as it isn't entirely apparent which
VMAs may have these entries present, especially when performing actions
which walk through memory regions such as those performed by CRIU.
This series addresses this issue by introducing the VM_MAYBE_GUARD flag
which fulfils this role, updating the smaps logic to display an entry for
these.
The semantics of this flag are that a guard region MAY be present if set
(we cannot be sure, as we can't efficiently track whether an
MADV_GUARD_REMOVE finally removes all the guard regions in a VMA) - but if
not set the VMA definitely does NOT have any guard regions present.
It's problematic to establish this flag without further action, because
that means that VMAs with guard regions in them become non-mergeable with
adjacent VMAs for no especially good reason.
To work around this, this series also introduces the concept of 'sticky'
VMA flags - that is flags which:
a. if set in one VMA and not in another still permit those VMAs to be
merged (if otherwise compatible).
b. When they are merged, the resultant VMA must have the flag set.
The VMA logic is updated to propagate these flags correctly.
Additionally, VM_MAYBE_GUARD being an explicit VMA flag allows us to solve
an issue with file-backed guard regions - previously these established an
anon_vma object for file-backed mappings solely to have vma_needs_copy()
correctly propagate guard region mappings to child processes.
We introduce a new flag alias VM_COPY_ON_FORK (which currently only
specifies VM_MAYBE_GUARD) and update vma_needs_copy() to check explicitly
for this flag and to copy page tables if it is present, which resolves
this issue.
Additionally, we add the ability for allow-listed VMA flags to be
atomically writable with only mmap/VMA read locks held.
The only flag we allow so far is VM_MAYBE_GUARD, which we carefully ensure
does not cause any races by being allowed to do so.
This allows us to maintain guard region installation as a read-locked
operation and not endure the overhead of obtaining a write lock here.
Finally we introduce extensive VMA userland tests to assert that the
sticky VMA logic behaves correctly as well as guard region self tests to
assert that smaps visibility is correctly implemented.
This patch (of 9):
Currently, if a user needs to determine if guard regions are present in a
range, they have to scan all VMAs (or have knowledge of which ones might
have guard regions).
Since commit 8e2f2aeb8b48 ("fs/proc/task_mmu: add guard region bit to
pagemap") and the related commit a516403787e0 ("fs/proc: extend the
PAGEMAP_SCAN ioctl to report guard regions"), users can use either
/proc/$pid/pagemap or the PAGEMAP_SCAN functionality to perform this
operation at a virtual address level.
This is not ideal, and it gives no visibility at a /proc/$pid/smaps level
that guard regions exist in ranges.
This patch remedies the situation by establishing a new VMA flag,
VM_MAYBE_GUARD, to indicate that a VMA may contain guard regions (it is
uncertain because we cannot reasonably determine whether a
MADV_GUARD_REMOVE call has removed all of the guard regions in a VMA, and
additionally VMAs may change across merge/split).
We utilise 0x800 for this flag which makes it available to 32-bit
architectures also, a flag that was previously used by VM_DENYWRITE, which
was removed in commit 8d0920bde5eb ("mm: remove VM_DENYWRITE") and hasn't
bee reused yet.
We also update the smaps logic and documentation to identify these VMAs.
Another major use of this functionality is that we can use it to identify
that we ought to copy page tables on fork.
We do not actually implement usage of this flag in mm/madvise.c yet as we
need to allow some VMA flags to be applied atomically under mmap/VMA read
lock in order to avoid the need to acquire a write lock for this purpose.

not using in USB-C complex
The QMP USB3/DP Combo PHY hosts an USB3 phy and a DP PHY on top
of a combo glue to route either lanes to the 4 shared physical lanes.
The routing of the lanes can be:
- 2 DP + 2 USB3
- 4 DP
- 2 USB3
The layout of the lanes was designed to be mapped and swapped
related to the USB-C Power Delivery negociation, so it supports
a finite set of mappings inherited by the USB-C Altmode layouts.
Nevertheless those QMP Comby PHY can be used to drive a DisplayPort
connector, DP->HDMI bridge, USB3 A Connector, etc... without
an USB-C connector and no PD events.
Document the data-lanes on numbered port@0 out endpoints,
allowing us to document the lanes mapping to DisplayPort

Bean Huo <beanhuo@iokpp.de> says:
This patch series introduces OP-TEE based RPMB (Replay Protected
Memory Block) support for UFS devices, extending the kernel-level
secure storage capabilities that are currently available for eMMC
devices.
Previously, OP-TEE required a userspace supplicant to access RPMB
partitions, which created complex dependencies and reliability issues,
especially during early boot scenarios. Recent work by Linaro has
moved core supplicant functionality directly into the Linux kernel for
eMMC devices, eliminating userspace dependencies and enabling
immediate secure storage access. This series extends the same approach
to UFS devices, which are used in enterprise and mobile applications
that require secure storage capabilities.
Benefits:
- Eliminates dependency on userspace supplicant for UFS RPMB access
- Enables early boot secure storage access (e.g., fTPM, secure UEFI
variables)
- Provides kernel-level RPMB access as soon as UFS driver is
initialized
- Removes complex initramfs dependencies and boot ordering
requirements
- Ensures reliable and deterministic secure storage operations
- Supports both built-in and modular fTPM configurations.
Prerequisites:

This patch series depends on commit 7e8242405b94 ("rpmb: move struct

On pic64gx these syscons are identical to those on mpfs, and should use
a fallback. Add support for multiple fallback compatibles to syscon.yaml
with these as the first two users.

Some PWM LED driver chips like TPS92380 and LT3743 require a separate
enable signal in addition to PWM control. Add this property to allow
device trees to specify such GPIO, which will be controlled
automatically by the driver based on the LED brightness state.

Different SoCs have different numbers of Wireless Ethernet
Dispatch (WED) units:
- MT7981: Has 1 WED unit
- MT7986: Has 2 WED units
- MT7988: Has 2 WED units
Update the binding to reflect these hardware differences. The MT7981
also uses infracfg for PHY switching, so allow that property.

Reason for moving from simple panel is this DDIC has three supplies,
while panel-simple-dsi is limited to one.
Previous compatible only described the DDIC, but didn't include panel
connected to it. Let's fix it, and offer bindings authors two
compatibles to distinguish the connected panel.
Basic description for SOFEF00 DDIC with attached panels
- Samsung AMS601NT22 6.01 inch, 1080x2160 pixels, 18:9 ratio
- Samsung AMS628NW01 6.28 inch, 1080x2280 pixels, 19:9 ratio
There is only one user which uses samsung,sofef00 and it's updated to
comply within this patch series.

Add missing ref on panel-common.yaml for this dsi panel so that common
properties can be shared.
Drop reset-gpios and backlight as they are already in panel-common.
Switch from additionalProperties to unevaluatedProperties so that common
panel properties are available without repeating them in this binding.
Notably panel-common defines the "port" property for linking panels to a
source - which was missing from this panel. Mark it as required.
