drm/amd/display: Fix redundant GPUVMEnable checks in dcn6 flip schedule
Inside dcn6_calculate_flip_schedule(), GPUVMEnable is already checked in
the outer if block. But the same GPUVMEnable is checked again in two
inner if blocks inside it. Since GPUVMEnable is always true at that
point, the inner else branches that assign meta_row_height are never
reached.
Remove the redundant inner GPUVMEnable checks and directly assign
dpte_row_height, which is always the correct value here.

drm/amd/display: Fix wrong bytes-per-pixel value for dml2_422_packed_10
The pixel format dml2_422_packed_10 needs BytePerPixelDETY set to
8.0/3. But it was accidentally placed in the wrong group that sets it to
4, so the correct value was never used.
This caused wrong DET buffer size and bandwidth calculations whenever
this format was used.
Fix it by moving dml2_422_packed_10 out of the wrong group so it gets
the correct value of 8.0/3.

drm/amdkfd: guard against NULL restore_mqd in CRIU queue restore
Both create_queue_cpsch() and create_queue_nocpsch() unconditionally
call mqd_mgr->restore_mqd() when a CRIU restore is in progress
(qd != NULL), with no NULL guard. On any system where restore_mqd is
not implemented for the given queue type, a user holding
CAP_CHECKPOINT_RESTORE can trigger a kernel NULL pointer dereference
and panic the machine by issuing KFD_IOC_CRIU_OP_RESTORE with a
crafted queue restore object. Note that checkpoint_mqd is likewise
unimplemented on GFX12, so no legitimate CRIU image can reach this
path — only a hand-crafted restore payload.
Add a NULL guard for restore_mqd immediately after mqd_mgr is
resolved, unwinding via the existing error labels and returning
-EOPNOTSUPP if the callback is not implemented. This mirrors the
existing checkpoint_mqd guard in checkpoint_mqd().

drm/amdkfd: Fix the case that vm range is hole at svm_migrate_copy_to_vram
When migration vm range is hole at cpu side(MIGRATE_PFN_MIGRATE set + MIGRATE_PFN_VALID unset) driver still allocates device pages. There is no dma map of src pages and migration. j is 0 and svm_migrate_copy_memory_gart() will return an uninitialized r. That can trigger out_free_vram_pages to drop all VRAM just set up. Initialize r and only call the last svm_migrate_copy_memory_gart if j > 0. Current code postponed the last page to the final copy. This patch flushes on the last page when reach to the end of current drm_buddy_block; avoids another svm_migrate_copy_memory_gart.

drm/amdkfd: Fix error path at svm_migrate_copy_to_ram
If page migration from device to sys ram fails for some reasons driver needs release and unlock allocated system pages. To do that driver should use page physical address, or pfn, then get struct page*. Current driver uses dma address(for adev) that is not correct with IOMMU enabled, or even in general. The patch releases and unlocks allocated system pages based on where migration failed by struct page* of sys ram pages. Also dma_unmap correspodent system ram pages at error path.

drm/amd/display: Fix HPD consideration for VGA/LVDS connectors on DCE
After a refactor that landed in Linux 7.0,
DC now crashes when it is initialized on GPUs
that have a VGA or LVDS connector. This is because
these connectors have no HPD so the hpd_gpio is NULL
and therefore DC takes the code path meant for
DCN 4.2+ which sets irq_source_hpd = 255 that
causes the subsequent code to try to register
the HPD interrupt, which fails, and causes
a crash.
This commit should be backported to Linux 7.0 and newer.

drm/amdgpu: clamp the isolation index for rings outside a partition
adev->isolation[] has one slot per partition, but a ring that is not assigned to one keeps AMDGPU_XCP_NO_PARTITION, which is ~0, so indexing the array with it is out of bounds. SDMA submissions hit this on both the isolation enforcement and the VM flush path and trip UBSAN. Fall back to the first slot the way the cleaner shader path already does, and stop taking the address before the ring type check that makes it relevant.

drm/amdkfd: Reject zero-sized AQL queue allocations after size halving
KFD_IOC_ALLOC_MEMORY_OF_GPU with flag KFD_IOC_ALLOC_MEM_FLAGS_AQL_QUEUE_MEM and size=1 triggers the AQL wraparound workaround (size >>= 1), reducing size to 0. The resulting zero passes through PAGE_ALIGN(0) = 0 without validation, bypassing the per-process VRAM quota check in reserve_mem_limit() (vram_used + 0 > vram_available is always false). The fix adds post-halving zero-size validation in the primary allocation path (amdgpu_amdkfd_gpuvm.c). The check happens after size halving but before reserve_mem_limit(), and uses err_alignment_size error path to properly clean up the allocated kgd_mem structure and mutex.

Harden remoteproc lifecycle handling by attaching asynchronously, stopping crashed processors, synchronizing crash work with removal, and forcing shutdown before device resources are released. Reallocate resources during attach recovery and fix several reference and error-path leaks. Add Xilinx R5 crash detection and move RPU start and stop sequencing into the platform firmware driver. Consolidate write-combining carveout mapping callbacks, use correct I/O-memory accessors, and share optional ELF resource-table handling across drivers.

This makes `rusttest` fail because the compiler finds both the sysroot

Arm:
* Add support for 'slot' based PMU events, paired with new UAPI that
compels the user to select a specific PMU implementation
* Lazy save/restore of vCPU state for pKVM, along with various fixes
and cleanups to the management of vCPU state between the untrusted
host and pKVM hypervisor
* Disable traps of EL1 registers for nested hypervisors when FEAT_NV2p1
is present, guaranteeing that EL2-specific register bits are stateful
in the EL1 counterpart
* Leverage FEAT_NV3 to avoid unnecessary ERET/TLBI traps when the scope
of those instructions remains 'in host' (i.e. L1 kernel/userspace)
* Pile of fixes for the management of the VNCR pseudo-TLB, such as
under-invalidations and races with concurrent TLBIs on other vCPUs
* Consolidate the non-protected and pKVM view of ICH_VTR_EL2 to a
runtime-patched constant, allowing the same data to be shared with
pKVM prior to dropping host privileges
* Considerable pile of LLM-assisted fixes around the shop but mostly in
the VGIC, our in-kernel generator of bugs (and sometimes interrupts)
LoongArch:
* Advertise already-supported capabilities.
* Some bug fixes about timer and MMIO.
* Some hardening about interrupt injection.
* Replace kvm_err() with kvm_pr_unimpl().
* Add FPU/LSX/LASX test cases for selftests.
RISC-V:
* Svadu/Zicfiss/Zicfilp FWFT support for Guest
* Use try_cmpxchg for IMSIC MRIF RMW
* More arch-specific tracepoints in KVM RISC-V
* Eager page splitting when enabling dirty logging
* Optimize hfence request handling for SMP Guests
* Improve dirty log clearing by skipping zero bits in mask
* Guard HFENCE range loops against overflow
* CPU PM notifiers in KVM RISC-V for non-retentive idle states
* Fix kernel-mode vector context save/restore for Guest
s390:
* Fixes for vfio-ap
* Fixes for the gmap rework
* Fixes for vsie
* AI triggered fixes all over
* diag9c tracing
* code move preparation for the additional arm64 support
* enable CONTEXT_ANALYSIS
x86:
* Perform spring cleaning on x86.{c,h} and asm/kvm_host.h, by adding regs.c
(the kvm_cache_regs.h => regs.h is already applied) and msrs.{c,h}, and moving
relevant code out of x86.c.
* Split kvm_mmu in three parts, respectively to describe the format of page
tables, walking the guest page tables and building the page tables. Always
use the same page table walker kvm->arch.gva_walk as the entry point to
convert a guest's virtual address, where the previous code used two
different kvm_mmu structs depending on whether the walk included nested
EPT/NPT or not. Make page fault vmexits reuse the permission checking
machinery that is used for guest page faults. This is both a cleanup
and a baby step towards supporting XS/XU memory permissions.
* Document some of the "fun" gotchas with the APIC base when creating IRQCHIPs
on x86.
* Remove a defunct masterclock update from kvm_xen_shared_info_init(). It
could result in incorrect kvmclock due to triggering an unnecessary
switch to/from masterclock mode.
* Skip Xen runstate time updates if time has effectively gone backwards, so
that the guest doesn't report 100% steal time for a very, very long time.
* Drop KVM's runtime updates of the Xen PV timing CPUID leaf, as KVM was
updating the wrong sub-leaf, and upstream KVM will soon provide all the
information needed by userspace to populate the CPUID field itself.
* Fix a bug where KVM would walk a newly created rmap without holding the rmap
lock (or mmu_lock) during aging.
* Fix a bug where aging TDP MMU SPTEs could clobber FROZEN SPTEs.
* Fix a variety of #DB priority bugs.
* Fix a class of races related to enabling Hyper-V emulation on a vCPU after
the vCPU is visible to the rest of KVM.
* Use static calls for nested virtualization ops.
* Move more KVM-internal code out of x86's kvm_host.h.
* Enumerate support for a variety of Zhaoxin instructions that don't require
explicit virtualization.
* Fix missing EFER validation bugs, including in the KVM_SET_SREGS* path.
* Harden kvm_vcpu_map() against double-mapping and thus leaking references.
* Misc fixes and cleanups, e.g. for largely benign syzkaller splats.
x86 (Intel):
* Zero a vCPU's entry in VMX's Posted Interrupt Descriptor table used for IPI
virtualization when the vCPU is freed, to fix a use-after-free where hardware
will write to a freed vCPU's PID.
* Service local TLB flushes on a failed nested VM-Enter to fix a bug where KVM
could miss a TLB on a future, successful VM-Enter with the same L2 VPID.
* Cap the maximum value shoved into the VMX Preemption Timer to workaround an
erratum that affects all existing Intel CPUs that support CPUID 0x15.
* Fix VPID virtualization bugs where KVM would fail to flush hardware TLBs.
* Harden the TDX "populate" ioctls against bad input, and to prepare
for supporting in-place private<=>shared conversion.
x86 (AMD):
* Forcefully invalidate SNP VMSA pages if their backing guest_memfd page is
zapped/invalidated, e.g. due to a PUNCH_HOLE in response to a Page-State
Change request.
* Remove a dying VM from the GA Log notifier list before the VM is actually
destroyed, to fix a potential use-after-free.
* While FOLL_WRITE was needed in the past to trigger CoW unsharing, nowadays
FOLL_LONGTERM does that already even without FOLL_WRITE, and in fact,
get_user_pages() actually disallows FOLL_WRITE together with FOLL_LONGTERM.
So don't pass FOLL_WRITE when registering encrypted memory regions, i.e. when
pinning SEV/SEV-ES guest memory, to fix a regression with file-backed memory
introduced by KVM's (correct) usage of long-term pins.

io_uring/waitid: avoid siginfo copy during ring teardown
During ring teardown, io_ring_exit_work() cancels outstanding requests
from a kworker with a NULL tctx. The waitid cancellation path eventually
reaches io_waitid_finish(), which copies the stored siginfo to the
userspace pointer supplied with the request.
Ring-wide teardown does not run in the task context that submitted the
request, so it must not access that task's userspace pointer. Depending
on the address and mm state, the copy may fail with -EFAULT, but the
uaccess itself is inappropriate from the teardown kworker.
Use a no-copy cancellation callback when io_waitid_remove_all() is
called without an owning task context. Complete the request with
-ECANCELED while releasing the waitid state without touching siginfo.
Keep the existing siginfo handling for explicit async cancellation and
task-scoped cancellation.
Fixes:

io_uring/waitid: honor task_work cancellation
io_waitid_cb() may run through the fallback task_work path when
task_work_add() can no longer queue work to the originating task. The
fallback runs from a kworker and io_uring marks such task work as
canceled through tw.cancel.
io_waitid_cb() currently ignores tw.cancel and calls __do_wait().
waitid is task-context dependent: __do_wait() performs child lookup
relative to current, and the retry path also uses
current->signal->wait_chldexit. If the callback runs from the fallback
kworker, current is therefore not the task that submitted the request.
Honor tw.cancel before entering __do_wait(). Complete the request with
-ECANCELED and skip the siginfo copy, since canceled task work may run
without the submitting task's userspace execution context.
Keep the existing siginfo handling for normal waitid completion and
explicit cancellation.

io_uring/query: cap user size passed to copy_struct_to_user
io_handle_query_entry() clamps hdr.size for the inbound copy_from_user()
but keeps the original user value as usize. copy_struct_to_user() uses
that usize and, when it is larger than the kernel result, clear_user()s
the trailing bytes.
As hdr.size is a __u32, a query can request nearly 4 GiB of zeroing,
including on the error path where res_size stays 0. The interface is
reachable without a ring via IORING_REGISTER_QUERY.
Reject sizes larger than PAGE_SIZE, as recommended for copy_struct_*
interfaces.

Char/Misc/IIO/etc driver update for 7.3-rc1
Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.
Overall, due to some driver removals we only added a bit more code than
removed, which was a nice change. Highlights in this merge request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used anymore
- Coresight driver updates and additions
- Mei driver udpates
- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported
issues
All of these have been in linux-next for a while, with the only reported
issues being some major merge conflicts. Miguel pointed out some of
these with the Rust tree merge, which is the majority of them. I'll
follow up with a diffstat of the merge resolution I made against your
most recent tree, which works for me.

This contains 52 commits with improvements to compression support,
metadata handling, error propagation, and filesystem robustness.
New feature:
- Add optional read support for Windows System Compression (WOF).
Add CONFIG_NTFS_FS_WOF_COMPRESSION and support reading WOF-compressed
files through the NTFS page-read path. This includes parsing
REPARSE_TAG_WOF, handling resident and non-resident WOF metadata and

decompressors. The codecs use a common transparent compression interface
shared with LZNT1. WOF support is read-only and disabled unless

in decompression, MFT allocation, and index conversion paths, clean up MFT
mappings and attribute search contexts on failure, and propagate attribute

- Improve compressed-file I/O path.
Fix compressed writes on large-page and highmem systems, reuse compression
contexts and output workspaces, avoid unnecessary reads for full-unit
overwrites, and submit one bio per compressed write unit. Write replacement
data before publishing the new mapping, correctly handle zero-filled
compressed blocks, and fix initialized-size and folio state updates after
compressed writes.
- Synchronize resident reads with MFT record updates.
- Validate the final EA stream size before modifying existing data, rewrite
the stream safely when replacing entries, restore the previous state when
metadata updates fail, and remove the EA attribute pair when the last
entry is deleted.
- Apply Windows filename restrictions only when windows_names is enabled.

lacks sufficient space.
- Move non-resident attribute payload data before shrinking its record.
- Correct resident-to-non-resident conversion when compression or sparse
flags are enabled.
- Prepare file allocation and initialized-size updates before buffered or
direct I/O submission, and use pagecache_isize_extended() when extending
the file size.
- Fix highmem and page/folio access in compressed I/O paths by using the
correct local mappings and page helpers.
- Apply per-file $LXMOD permissions instead of mount masks when available,
and prevent unprivileged writes to reserved $LX* attributes.
- Update the NTFS maintainer mailing list.
- Four small cleanups.

f2fs: accurately adjust free_sections during free_segment_range
In free_segment_range(), MAIN_SECS(sbi) is temporarily reduced by `secs`
to restrict block allocation to the safe remaining main area while valid
blocks in the truncated range are evacuated by GC.
However, FREE_I(sbi)->free_sections tracks the total number of free
sections across the whole filesystem. If any sections within the
truncated range were already free upon entering free_segment_range(),
failing to deduct them from free_sections causes the filesystem to
overestimate available free sections in the active, reduced main area.
This leads to inconsistent free section accounting during GC data
migration and can trigger unexpected allocation failures or assertion
errors when space is tight.
Fix this by calculating the number of already-free sections in the
truncated range, deducting them from free_sections upon entering
free_segment_range(), and restoring them on exit.

tpm-buf: Memory-safe allocations
Decouple kzalloc from buffer creation, so that a managed allocation can be used: struct tpm_buf *buf __free(kfree) buf = kzalloc(TPM_BUFSIZE, GFP_KERNEL); if (!buf) return -ENOMEM; tpm_buf_init(buf, TPM_BUFSIZE); Alternatively, other allocations are also possible (static data, stack, etc) for example: u8 buf_data[512]; struct tpm_buf *buf = (struct tpm_buf *)buf_data; tpm_buf_init(buf, sizeof(buf_data)); This is achieved by embedding buffer's header inside the allocated blob, instead of having an outer wrapper.

These are definitions for TPM 2.0 interface and interactions with the platform as defined in the TCG specification: These definitions are located here in a separate file to avoid conflicts with vendor specific TIS/FIFO definition (e.g. STMicroelectronics, Infineon Technologies, etc). This allows the TCG defined TIS/FIFO interface to be in a public header while the former chip specific implementations contain their own definitions.

tpm: st33zp24: Validate locality read result
check_locality() treats every nonzero transport return as success. SPI
errors remain negative, while the I2C path can convert a negative write
error through its byte-sized status variable. Either result is nonzero
even though the TPM_ACCESS byte can remain unwritten, so indeterminate
ACTIVE_LOCALITY and VALID bits can falsely report an active locality.
Require recv() to return exactly the requested byte before examining
TPM_ACCESS. Transport errors and short reads now report an inactive
locality, while successful reads retain the existing behavior.
This issue was found by a static analysis checker and confirmed by manual
source review.

tpm: st33zp24: Return zero on status read failure
st33zp24_status() ignores the result of the transport read and returns
data even when no byte was received. The I2C transport, for example,
skips i2c_master_recv() when the register-select write is short or fails,
leaving data uninitialized. The resulting stack value can be interpreted
as TPM_STS flags and let status checks complete spuriously.
The status callback cannot propagate a transport error. Return zero
unless recv() reports exactly one byte. With no status bits set, callers
retry or take their existing timeout or error path instead of acting on
an invalid status value.

tpm: atmel: depend on X86
tpm_atmel probes for the chip at fixed x86 Super-I/O ports (0x4e) with
inb()/outb(), so it only works on x86. TCG_ATMEL nevertheless depends
only on HAS_IOPORT_MAP/HAS_IOPORT, which arm and arm64 also satisfy.
There the probe is useless, and on platforms whose unbacked I/O access
faults it oopses in init_atmel() at boot (e.g. arm/versatile):
Unable to handle kernel paging request at virtual address fee0004e
PC is at init_atmel+0x34/0x244
