4340ca47c3 erofs: decouple struct erofs_anon_fs_type
- Move the `struct erofs_anon_fs_type` to super.c and expose it
    in preparation for the upcoming page cache share feature;

  - Remove the `.owner` field, as they are all internal mounts and
    fully managed by EROFS.  Retaining `.owner` would unnecessarily
    increment module reference counts, preventing the EROFS kernel
    module from being unloaded.

3736449704 fs: Export alloc_empty_backing_file
There is no need to open nonexistent real files if backing files
couldn't be backed by real files (e.g., EROFS page cache sharing
doesn't need typical real files to open again).

Therefore, we export the alloc_empty_backing_file() helper, allowing
filesystems to dynamically set the backing file without real file
open. This is particularly useful for obtaining the correct @path
and @inode when calling file_user_path() and file_user_inode().

230b080623 KVM: arm64: Use kvm_has_mte() in pKVM trap initialization
When initializing HCR traps in protected mode, use kvm_has_mte() to
check for MTE support rather than kvm_has_feat(kvm, ID_AA64PFR1_EL1,
MTE, IMP).

kvm_has_mte() provides a more comprehensive check:
 - kvm_has_feat() only checks if MTE is in the guest's ID register view
   (i.e., what we advertise to the guest)
 - kvm_has_mte() checks both system_supports_mte() AND whether
   KVM_ARCH_FLAG_MTE_ENABLED is set for this VM instance

5ee8ad69da KVM: arm64: Inject UNDEF when accessing MTE sysregs with MTE disabled
When MTE hardware is present but disabled via software (`arm64.nomte` or
`CONFIG_ARM64_MTE=n`), the kernel clears `HCR_EL2.ATA` and sets
`HCR_EL2.TID5`, to prevent the use of MTE instructions.

Additionally, accesses to certain MTE system registers trap to EL2 with
exception class ESR_ELx_EC_SYS64. To emulate hardware without MTE (where
such accesses would cause an Undefined Instruction exception), inject
UNDEF into the host.

f35abcbb8a KVM: arm64: Trap MTE access and discovery when MTE is disabled
If MTE is not supported by the hardware, or is disabled in the kernel
configuration (`CONFIG_ARM64_MTE=n`) or command line (`arm64.nomte`),
the kernel stops advertising MTE to userspace and avoids using MTE
instructions. However, this is a software-level disable only.

When MTE hardware is present and enabled by EL3 firmware, leaving
`HCR_EL2.ATA` set allows the host to execute MTE instructions (STG, LDG,
etc.) and access allocation tags in physical memory.

Prevent this by clearing `HCR_EL2.ATA` when MTE is disabled. Remove it
from the `HCR_HOST_NVHE_FLAGS` default, and conditionally set it in
`cpu_prepare_hyp_mode()` only when `system_supports_mte()` returns true.
This causes MTE instructions to trap to EL2 when `HCR_EL2.ATA` is
cleared.

Additionally, set `HCR_EL2.TID5` when MTE is disabled. This traps reads
of `GMID_EL1` (Multiple tag transfer ID register) to EL2, preventing the
discovery of MTE parameters (such as tag block size) when the feature is
suppressed.

Early boot code in `head.S` temporarily keeps `HCR_ATA` set to avoid
special-casing initialization paths. This is safe because this code
executes before untrusted code runs and will clear `HCR_ATA` if MTE is
disabled.

c103c2dfe4 KVM: arm64: Remove dead code resetting HCR_EL2 for pKVM
The pKVM lifecycle does not support tearing down the hypervisor and
returning to the hyp stub once initialized. The transition to protected
mode is one-way.

Consequently, the code path in hyp-init.S responsible for resetting
EL2 registers (triggered by kexec or hibernation) is unreachable in
protected mode.

Remove the dead code handling HCR_EL2 reset for
ARM64_KVM_PROTECTED_MODE.

No functional change intended.

15257cc2f9 sched/fair: Revert force wakeup preemption
This agressively bypasses run_to_parity and slice protection with the
assumpiton that this is what waker wants but there is no garantee that
the wakee will be the next to run. It is a better choice to use
yield_to_task or WF_SYNC in such case.

This increases the number of resched and preemption because a task becomes
quickly "ineligible" when it runs; We update the task vruntime periodically
and before the task exhausted its slice or at least quantum.

Example:
2 tasks A and B wake up simultaneously with lag = 0. Both are
eligible. Task A runs 1st and wakes up task C. Scheduler updates task
A's vruntime which becomes greater than average runtime as all others
have a lag == 0 and didn't run yet. Now task A is ineligible because
it received more runtime than the other task but it has not yet
exhausted its slice nor a min quantum. We force preemption, disable
protection but Task B will run 1st not task C.

Sidenote, DELAY_ZERO increases this effect by clearing positive lag at
wake up.

4f70f106bc sched/fair: Disable scheduler feature NEXT_BUDDY
NEXT_BUDDY was disabled with the introduction of EEVDF and enabled again
after NEXT_BUDDY was rewritten for EEVDF by commit e837456fdc ("sched/fair:
Reimplement NEXT_BUDDY to align with EEVDF goals"). It was not expected
that this would be a universal win without a crystal ball instruction
but the reported regressions are a concern [1][2] even if gains were
also reported. Specifically;

o mysql with client/server running on different servers regresses
o specjbb reports lower peak metrics
o daytrader regresses

The mysql is realistic and a concern. It needs to be confirmed if
specjbb is simply shifting the point where peak performance is measured
but still a concern. daytrader is considered to be representative of a
real workload.

Access to test machines is currently problematic for verifying any fix to
this problem. Disable NEXT_BUDDY for now by default until the root causes
are addressed.

fs/file: optimize close_range() complexity from O(N) to O(Sparse)
In close_range(), the kernel traditionally performs a linear scan over the
[fd, max_fd] range, resulting in O(N) complexity where N is the range size.
For processes with sparse FD tables, this is inefficient as it checks many
unallocated slots.

This patch optimizes __range_close() by using find_next_bit() on the
open_fds bitmap to skip holes. This shifts the algorithmic complexity from
O(Range Size) to O(Active FDs), providing a significant performance boost
for large-range close operations on sparse file descriptor tables.

The Rust compiler cannot use dependencies built by other versions, e.g.:

    error[E0514]: found crate `proc_macro2` compiled by an incompatible version of rustc
     --> rust/quote/ext.rs:5:5
      |
    5 | use proc_macro2::{TokenStream, TokenTree};
      |     ^^^^^^^^^^^
      |
      = note: the following crate versions were found:
              crate `proc_macro2` compiled by rustc 1.92.0 (ded5c06cf 2025-12-08): ./rust/libproc_macro2.rlib
      = help: please recompile that crate using this compiler (rustc 1.93.0 (254b59607 2026-01-19)) (consider running `cargo clean` first)

Thus trigger a rebuild if the version text changes like we do in other
top-level cases (e.g. see commit aeb0e24abb ("kbuild: rust: replace
proc macros dependency on `core.o` with the version text")).

The build errors for now are hard to trigger, since we do not yet use
the new crates we just introduced (the use cases are coming in the next
merge window), but they can still be seen if e.g. one manually removes
one of the targets, so fix it already.

Add support for Armada 7020 Express Type 7 CPU module board by Marvell.
Define this COM Express CPU module as dtsi and provide a dtsi file for
the carrier board (Marvell DB-98CX85x0 COM Express type 7 carrier board).

Since memory is soldered on CPU module, memory node is on CPU module
dtsi file.

This Carrier board only utilizes the PCIe link, hence no special device
or driver support is provided by this dtsi file.
Devise a dts file for the combined com express carrier and CPU module.

The Aramda 7020 CPU COM Express board offers the following features:

1.  Armada 7020 CPU, with dual ARM A72 cores
2.  DDR4 memory, 8GB, on board soldered
3.  1Gbit Out of Band Ethernet via RGMII to PHY and RJ45 connector,
    all are present on A7K CPU module (none on the carrier)
4.  Optional 10G KR Ethernet going via the COM Express type 7 connector
5.  On-board 8 Gbit, 8-bit bus width NAND flash
6.  On-board 512 Mbit SPI flash
7.  PCIe Root Complex, 4 lanes PCIe gen3 connectivity, going via the
    COM Express type 7 connector
8.  m.2 SATA connector
9.  Micro-SD card connector
10. USB 2.0 via COM Express type 7 connector
11. Two i2c interfaces - one to the CPU module, and one to the
    carrier board via the COM Express type 7 connector
12. UART (mini USB connector by virtue of FT2232D UART to USB
    converter, connected to the Armada 7020 UART0)

0ecd890e3c PCI: dwc: Rename dw_pcie_rp::has_msi_ctrl to dw_pcie_rp::use_imsi_rx for clarity
The current "has_msi_ctrl" flag name is misleading because it suggests the
presence of any MSI controller, while it is specifically set for platforms
that lack .msi_init() callback and don't have "msi-parent" or "msi-map"
device tree properties, indicating they rely on the iMSI-RX module for MSI
functionality.

Rename it to "use_imsi_rx" to make the intent clear:
- When true: Platform uses the iMSI-RX module for MSI handling
- When false: Platform has other MSI controller support (ITS/MBI, external
MSI controller)

No functional changes, only improves code readability and eliminates
naming confusion.

Centralizing the GRAPHICS_VER(xe) >= 20 check keeps MEM_COPY enabled
on Xe2+ and removes redundant per-platform plumbing.

c0008a29a0 hwrng: airoha - set rng quality to 900
Airoha uses RAW mode to collect noise from the TRNG. These appear to
be unprocessed oscillations from the tero loop. For this reason, they
do not have a perfect distribution and entropy. Simple noise compression
reduces its size by 9%, so setting the quality to 900 seems reasonable.
The same value is used by the downstream driver.

Compare the size before and after compression:
