In the tilcdc_crtc_atomic_check(), the tilcdc driver hand-crafts its own
implementation of drm_atomic_helper_check_crtc_primary_plane(). And it
does so by accessing the state pointer in drm_atomic_state->planes which
is deprecated.
Let's use the right helper here.

The vkms_crtc_atomic_check() function calls the deprecated
drm_atomic_get_existing_plane_state() helper for its internal mode
checking logic.
During atomic_check, the existing state is the new state and
drm_atomic_get_existing_plane_state() can thus be replaced by
drm_atomic_get_new_plane_state().

The drm_atomic_get_plane_state() function calls the deprecated
drm_atomic_get_existing_plane_state() helper to get find if a plane
state had already been allocated and was part of the given
drm_atomic_state.
At the point in time where drm_atomic_get_plane_state() can be called
(ie, during atomic_check), the existing state is the new state and
drm_atomic_get_existing_plane_state() can thus be replaced by
drm_atomic_get_new_plane_state().

Both vm->xef and XE_LRC_CREATE_USER_CTX indicate in xe_lrc_init that
the context originates from userspace. However, XE_LRC_CREATE_USER_CTX
has a broader scope as it may be set even when no vm->xef is present.
The XE_BO_FLAG_PINNED_LATE_RESTORE flag can be extended to both cases,
so there is no point in handling the two cases separately.
Let's combine vm->xef and XE_LRC_CREATE_USER_CTX checks to detect
userspace context.

In general, kernel structures should be allocated in the kernel-dedicated

does not need to reside there.

When using a separate VRAM region for kernel allocations,
some kernel structures, such as context userspace data,
should not reside in the VRAM region dedicated to the kernel.
The VRAM kernel region is intended only for allocations necessary
for driver operation. Allocations created via ioctl are long-lived
and not easily evictable. If this region runs out of space,
there may not be a fallback, which could cause failures.
To prevent this, add a new BO flag that explicitly forces the BO to be
allocated in the general-purpose VRAM region accessible to userspace,
avoiding the kernel-only VRAM region.

So far, kernel and userspace allocations have shared the same VRAM region.
However, in some scenarios, it may be necessary to reserve a separate
VRAM area exclusively for kernel allocations.
Let's add preliminary support for such a configuration.

- replaced for_each_bo_flag_vram with the improved
for_each_set_bo_vram_flag helper (Matthew)
- moved the VRAM flag iteration macro definition into xe_bo.c (Matthew)
- drop unused bo_flgas from bo_vram_flags_to_vram_placement (Matthew)
- use hweight32 helper in __xe_bo_fixed_placement for readability

During kexec reboots, RTC alarms that are fired during the kernel
transition experience delayed execution. The new kernel would eventually
honor these alarms, but the interrupt handlers would only execute after
the driver probe is completed rather than at the intended alarm time.
This is because pending alarm interrupt status from the previous kernel
is not properly cleared during driver initialization, causing timing
discrepancies in alarm delivery.
To ensure precise alarm timing across kexec transitions, enhance the
probe function to:
1. Clear any pending alarm interrupt status from previous boot.
2. Detect existing valid alarms and preserve their state.
3. Re-enable alarm interrupts for future alarms.

But the majority of new code is in the rust bindings and additions,
which includes:
- misc driver rust binding updates for read/write support, we can now
write "normal" misc drivers in rust fully, and the sample driver
shows how this can be done.
- Initial framework for USB driver rust bindings, which are disabled
for now in the build, due to limited support, but coming in through
this tree due to dependencies on other rust binding changes that
were in here. I'll be enabling these back on in the build in the
usb.git tree after -rc1 is out so that developers can continue to
work on these in linux-next over the next development cycle.
- Android Binder driver implemented in Rust.
This is the big one, and was driving a huge majority of the rust
binding work over the past years. Right now there are two binder
drivers in the kernel, selected only at build time as to which one
to use as binder wants to be included in the system at boot time.
The binder C maintainers all agreed on this, as eventually, they
want the C code to be removed from the tree, but it will take a few
releases to get there while both are maintained to ensure that the
rust implementation is fully stable and compliant with the existing
userspace apis.

git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull more RISC-V updates from Paul Walmsley:
- Support for the RISC-V-standardized RPMI interface.
RPMI is a platform management communication mechanism between OSes
running on application processors, and a remote platform management
processor. Similar to ARM SCMI, TI SCI, etc. This includes irqchip,
mailbox, and clk changes.
- Support for the RISC-V-standardized MPXY SBI extension.
MPXY is a RISC-V-specific standard implementing a shared memory
mailbox between S-mode operating systems (e.g., Linux) and M-mode
firmware (e.g., OpenSBI). It is part of this PR since one of its use
cases is to enable M-mode firmware to act as a single RPMI client for
all RPMI activity on a core (including S-mode RPMI activity).
Includes a mailbox driver.
- Some ACPI-related updates to enable the use of RPMI and MPXY.
- The addition of Linux-wide memcpy_{from,to}_le32() static inline
functions, for RPMI use.
- An ACPI Kconfig change to enable boot logos on any ACPI-using
architecture (including RISC-V)
- A RISC-V defconfig change to add GPIO keyboard and event device
support, for front panel shutdown or reboot buttons

Starting with 'commit 2297791c92d0 ("s390/cio: dont unregister
subchannel from child-drivers")', cio no longer unregisters
subchannels when the attached device is invalid or unavailable.
As an unintended side-effect, the cio_ignore purge function no longer
removes subchannels for devices on the cio_ignore list if no CCW device
is attached. This situation occurs when a CCW device is non-operational
or unavailable
To ensure the same outcome of the purge function as when the
current cio_ignore list had been active during boot, update the purge
function to remove I/O subchannels without working CCW devices if the
associated device number is found on the cio_ignore list.
Fixes: 2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers")

Pull kvm updates from Paolo Bonzini:
"This excludes the bulk of the x86 changes, which I will send
separately. They have two not complex but relatively unusual conflicts
so I will wait for other dust to settle.
guest_memfd:
- Add support for host userspace mapping of guest_memfd-backed memory
for VM types that do NOT use support KVM_MEMORY_ATTRIBUTE_PRIVATE
(which isn't precisely the same thing as CoCo VMs, since x86's
SEV-MEM and SEV-ES have no way to detect private vs. shared).
This lays the groundwork for removal of guest memory from the
kernel direct map, as well as for limited mmap() for
guest_memfd-backed memory.
For more information see:
- commit a6ad54137af9 ("Merge branch 'guest-memfd-mmap' into HEAD")
- guest_memfd in Firecracker:
https://github.com/firecracker-microvm/firecracker/tree/feature/secret-hiding
- direct map removal:
https://lore.kernel.org/all/20250221160728.1584559-1-roypat@amazon.co.uk/
- mmap support:
https://lore.kernel.org/all/20250328153133.3504118-1-tabba@google.com/
ARM:
- Add support for FF-A 1.2 as the secure memory conduit for pKVM,
allowing more registers to be used as part of the message payload.
- Change the way pKVM allocates its VM handles, making sure that the
privileged hypervisor is never tricked into using uninitialised
data.
- Speed up MMIO range registration by avoiding unnecessary RCU
synchronisation, which results in VMs starting much quicker.
- Add the dump of the instruction stream when panic-ing in the EL2
payload, just like the rest of the kernel has always done. This
will hopefully help debugging non-VHE setups.
- Add 52bit PA support to the stage-1 page-table walker, and make use
of it to populate the fault level reported to the guest on failing
to translate a stage-1 walk.
- Add NV support to the GICv3-on-GICv5 emulation code, ensuring
feature parity for guests, irrespective of the host platform.
- Fix some really ugly architecture problems when dealing with debug
in a nested VM. This has some bad performance impacts, but is at
least correct.
- Add enough infrastructure to be able to disable EL2 features and
give effective values to the EL2 control registers. This then
allows a bunch of features to be turned off, which helps cross-host
migration.
- Large rework of the selftest infrastructure to allow most tests to
transparently run at EL2. This is the first step towards enabling
NV testing.
- Various fixes and improvements all over the map, including one BE
fix, just in time for the removal of the feature.
LoongArch:
- Detect page table walk feature on new hardware
- Add sign extension with kernel MMIO/IOCSR emulation
- Improve in-kernel IPI emulation
- Improve in-kernel PCH-PIC emulation
- Move kvm_iocsr tracepoint out of generic code
RISC-V:
- Added SBI FWFT extension for Guest/VM with misaligned delegation
and pointer masking PMLEN features
- Added ONE_REG interface for SBI FWFT extension
- Added Zicbop and bfloat16 extensions for Guest/VM
- Enabled more common KVM selftests for RISC-V
- Added SBI v3.0 PMU enhancements in KVM and perf driver
s390:
- Improve interrupt cpu for wakeup, in particular the heuristic to
decide which vCPU to deliver a floating interrupt to.
- Clear the PTE when discarding a swapped page because of CMMA; this
bug was introduced in 6.16 when refactoring gmap code.
x86 selftests:
- Add #DE coverage in the fastops test (the only exception that's
guest- triggerable in fastop-emulated instructions).
- Fix PMU selftests errors encountered on Granite Rapids (GNR),
Sierra Forest (SRF) and Clearwater Forest (CWF).
- Minor cleanups and improvements
x86 (guest side):
- For the legacy PCI hole (memory between TOLUD and 4GiB) to UC when
overriding guest MTRR for TDX/SNP to fix an issue where ACPI
auto-mapping could map devices as WB and prevent the device drivers
from mapping their devices with UC/UC-.
- Make kvm_async_pf_task_wake() a local static helper and remove its
export.
- Use native qspinlocks when running in a VM with dedicated
vCPU=>pCPU bindings even when PV_UNHALT is unsupported.
Generic:
- Remove a redundant __GFP_NOWARN from kvm_setup_async_pf() as
__GFP_NOWARN is now included in GFP_NOWAIT.

Rename intel_get_linetime_us() to skl_wm_linetime_us() to better
reflect that it's not meant to be used for anything apart from
the watermark calculations.

intel_get_linetime_us() is a mess. Rewrite it in a straightforward
manner. Also the checks for the !active and pixel_rate==0 are
completely pointless here since we know that the plane is visible.

The line time used for the watermark calculations is supposed to
based on the plane's adjusted pixel rate, not the pipe's adjusted
pixel rate. The current code will give incorrect answers if plane
downscaling is used.

The RZ/G2L DU driver is now also used on other Renesas SoCs such as
RZ/V2H(P) and RZ/V2N. Restricting it to ARCH_RZG2L prevents enabling it
on these newer platforms.
Replace the ARCH_RZG2L dependency with ARCH_RENESAS to allow the driver
to be built on all relevant Renesas SoCs.

Add support for the internal I2C controllers of RTL9310 series based
SoCs to the driver for RTL9300. Add register definitions, chip-specific
functions and compatible strings for known RTL9310-based SoCs RTL9311,
RTL9312 and RTL9313.
Make use of a new device tree property 'realtek,scl' which needs to be
specified in case both or only the second master is used. This is
required due how the register layout changed in contrast to RTL9300,
which has SCL selection in a global register instead of a
master-specific one.

Use the scoped guard infrastructure which unlocks a mutex automatically
when the guard goes out of scope, instead of explicit lock and unlock.
This simplifies the code and control flow in rtl9300_i2c_smbus_xfer and
removes the need of using goto in error cases to unlock before
returning.

So far, the rtl9300_i2c_smbus_xfer code is quite a mess with function
calls distributed over the whole function setting different values in
different cases. Calls to rtl9300_i2c_config_xfer and
rtl9300_i2c_reg_addr_set are used in every case-block with varying
values whose meaning is not instantly obvious. In some cases, there are
additional calls within these case-blocks doing more things.
This is in general a bad design and especially really bad for
readability and maintainability because it distributes changes or
issues to multiple locations due to the same function being called with
different hardcoded values in different places.
To have a good structure, setting different parameters based on the
desired operation should not be interleaved with applying these
parameters to the hardware registers. Or in different words, the
parameter site should be mixed with the call site.
Thus, separate configuration and execution of an SMBus xfer within
rtl9300_i2c_smbus_xfer to improve readability and maintainability. Add a
new 'struct rtl9300_i2c_xfer' to carry the required parameters for an
xfer which are configured based on the input parameters within a single
switch-case block, without having any function calls within this block.
The function calls to actually apply these values to the hardware
registers then appear below in a single place and just operate on the
passed instance of 'struct rtl9300_i2c_xfer'. These are
'rtl9300_i2c_prepare_xfer' which combines applying all parameters of the
xfer to the corresponding register, and 'rtl9300_i2c_do_xfer' which
actually executes the xfer and does post-processing if needed.

Move the operation to set the read mode from config_xfer to probe.
The I2C controller of RTL9300 and RTL9310 support a legacy message mode
for READs with 'Read Address Data' instead of the standard format 'Write
Address ; Read Data'. There is no way to pass that via smbus_xfer, thus
there is no point in supported this in the driver and moreover no point
in setting this on every transaction. Setting this once in the probe
call is sufficient.

Move the register operation to set the SCL frequency to the
rtl9300_i2c_config_io function instead of the rtl9300_i2c_config_xfer
function. This rather belongs there next to selecting the current SDA
output line.
