Some boards, such as the Firefly-RK3399, do not connect the codec

KVM: s390: Fixes for 7.2
- several fixes for PCI passthru in s390 kvm
- fix a 7.2-rc regression in the adapter interrupt mapping code
FOLL_LONGTERM pinning fails for some memory types, such as file-backed
guest memory. As a result, kvm_s390_adapter_map() returns -EINVAL and
irqfd adapter registration fails even though interrupt delivery could
still work via the existing non-atomic path.
When FOLL_LONGTERM pinning fails, verify that the page is accessible
using a short-term pin instead. If the short-term pin succeeds, unpin
the page and add a map entry with pinned=false to preserve MAP/UNMAP
symmetry. The non-atomic irqfd path already performs short-term pinning
for interrupt delivery, so this restores the previous behavior for
memory that cannot be pinned long-term.
get_map_info() is updated to return NULL for unpinned entries so that
the atomic irqfd fast path falls back to the non-atomic path.
kvm_s390_adapter_unmap() and kvm_s390_unmap_all_adapters() skip dirty
marking and unpin for unpinned entries.
Update Documentation/virt/kvm/devices/s390_flic.rst to reflect the
new MAP/UNMAP behavior.

spi: dt-bindings: spacemit: add K3 SPI compatible
spi: spacemit: Correct TX FIFO slot calculation
The zero-copy Tx batch parser stops when it encounters an invalid
descriptor. If this happens after one or more continuation descriptors,
the Tx consumer can be advanced past fragments that are neither submitted
to the driver nor returned to userspace through the completion ring.
A similar problem occurs when a packet exceeds xdp_zc_max_segs. The
descriptors consumed up to the limit are released without completion, and
the remaining continuation descriptors can subsequently be interpreted
as the beginning of another packet.
Parse Tx batches in packet units and distinguish descriptors belonging to
complete valid packets from descriptors consumed while draining an
invalid or oversized packet. Return the former to the driver and append
the latter to the CQ address area so userspace can reclaim their UMEM
frames.
Treat a standalone invalid descriptor as a one-descriptor reclaim-only
packet. Advancing the Tx-ring consumer releases the ring slot, but does
not by itself return ownership of the referenced UMEM frame to userspace.
Once draining starts, continue until the packet's end-of-packet
descriptor is consumed. Preserve the drain state on the socket when EOP
has not yet been supplied, so draining can continue during a later call.
Leave incomplete but otherwise valid packets on the Tx ring.
Shared-UMEM pools using multi-buffer Tx also need packet-framed parsing.
Walk their Tx sockets one packet at a time, preserving the existing
per-socket fairness scheme, instead of using the legacy one-descriptor
fallback. Keep that fallback for shared pools that do not use
multi-buffer Tx. Since the drain state is maintained per socket and both
the singular and shared paths can resume an interrupted drain, changing
the socket list from singular to shared requires no special bind-time
transition.
CQ entries are positional, and drivers may complete only part of the Tx
work returned by xsk_tx_peek_release_desc_batch(). Therefore, reclaim-only
entries cannot be published immediately when earlier driver-visible
descriptors are still outstanding.
Track the number of driver-visible CQ entries preceding the reclaim
entries. Let xsk_tx_completed() publish partial hardware Tx completions,
and publish the reclaim entries only after every earlier Tx descriptor
has completed. Complete a reclaim-only batch immediately when there is no
driver-visible work in front of it, and prevent another Tx batch from
being appended while reclaim entries remain pending.
Also cap batch processing by the size of the pool's temporary descriptor
array, as Tx rings belonging to sockets sharing a UMEM may have different
sizes.
This ensures that every invalid Tx descriptor consumed by the ZC batch
path is either submitted to the driver as part of a valid packet or
returned to userspace without violating CQ completion ordering.

The user cannot use MTE on VMAs created by mapping a guest_memfd file,
as arch_calc_vm_flag_bits() does not set VM_MTE_ALLOWED.
When creating a guest_memfd backed memslot,
kvm_arch_prepare_memory_region() rejects the memslot if MTE is enabled for
the VM and if guest_memfd has been mapped in a VMA that intersects the
memslot.
However, the documentation for KVM_SET_USER_MEMORY_REGION2 explicitly
states that the only condition for userspace_addr is for it to be a legal
userspace address, but the mapping is not required to be valid nor
populated at memslot creation.
If userspace sets userspace_addr to an address that hasn't been mapped, or
if userspace_addr belongs to a VMA that isn't backed by the guest_memfd
file, or if the VMA doesn't intersect the memslot, memslot creation is
successful and KVM ends up with a VM with MTE and guest_memfd-backed
memslots.
The same happens if the order is reversed: when userspace enables MTE, KVM
does not check if memslots backed by guest_memfd are already present.
Fix both issues by rejecting guest_memfd-backed memslots when MTE is
enabled, and by rejecting MTE when guest_memfd-backed memslots are already
present.

In the nested state, the physical interrupt has already been
deactivated through the HW bit in the LR. The extra deactivation
would be harmless but can hit an errata case on AmpereOne, so
avoid it here.
On AmpereOne, deactivating a physical interrupt through
ICC_DIR_EL1 or ICC_EOIR1_EL1 (depending on EOImode) which is not
active, but is the highest priority pending interrupt causes the
cpu to lose the interrupt pending state and also prevents the
delivery of future interrupts.

A number of IFLA_BRPORT_* attributes are documented in the rt-link spec
as having the "flag" type, i.e. a payload-less NLA_FLAG attribute whose
meaning is presence-only. This does not match the kernel, which emits
these attributes with nla_put_u8() and validates them as NLA_U8 in
br_port_policy[]. The values are not mere presence flags but carry a u8
payload (0/1).
Convert these bridge port attributes from "flag" to "u8" so the spec
reflects the actual wire format.

A handful of vendor-extension entries indent continuation lines with a
tab character, while the rest of hwprobe.rst uses spaces. In addition,
many list items align their continuation lines under the 'm' of
':c:macro:' (column 7) rather than under the item text (column 4), so
the file mixes several indentation styles.
Replace the tabs with spaces and align every list item's continuation
lines under the item text, giving the whole file one consistent style.
Whitespace-only change, no functional change.

The io.stat section says that enabling the io.latency controller exposes
the depth, avg_lat and win stats in addition to the normal ones. However,
these io.latency-specific stats are debug stats and are only emitted when
the blkcg_debug_stats module parameter is enabled, which is disabled by
default.
Make this explicit so users do not expect these fields to appear in
io.stat by default, and qualify the usage text that suggests using
avg_lat to pick an io.latency target.

A small set of fixes that came in since -rc1, we have one core fix for
shutting down target mode properly if the system suspends while it's
running plus a small set of fairly unremarkable device specific fixes.
There's also a couple of pure DT binding changes for Renesas SoCs, the
power domains one allows some SoCs to be correctly described with
existing code.

Pull smb server fixes from Steve French:
- Fix several use-after-free races in durable handle reconnect,
supersede, and oplock handling
- Avoid holding the inode oplock lock while waiting for a lease break
acknowledgement. This removes delays of up to 35 seconds when cifs.ko
closes a deferred handle in response to a lease break
- Fix malformed security descriptor handling, including an undersized
DACL allocation issue and an out-of-bounds ACE SID read
- Fix memory leaks in security descriptor and DOS attribute xattr
encoding/decoding error paths
- Fix outstanding SMB2 credit leaks on aborted requests and correct the
QUERY_INFO credit charge calculation
- Fix hard-link creation without replacement being incorrectly rejected
when the handle lacks DELETE access
- Avoid unnecessary zeroing of large SMB2 read buffers
- Add an oplock list lockdep annotation and update the documented
support status for durable handles and SMB3.1.1 compression
- Durable handle fixes to address ownership and lifetime races during
reconnect, session teardown, oplock handling, and superseding opens,
preventing stale session and file references from being used by
concurrent operations

- Fix racy bitfield updates in vfio-pci-core and the mlx5 vfio-pci
variant driver with a binary split between setup/release and
runtime modified flags. These were noted across several Sashiko
reviews as pre-existing issues. (Alex Williamson)
- Fix runtime PM inconsistency where the vfio-pci driver module_init
could modify the idle PM policy of existing devices through globals
managed in vfio-pci-core, leading to unbalanced runtime PM
operations. (Alex Williamson)
- Restore mutability of writable vfio-pci module options by further
pulling policy globals out of vfio-pci-core, to instead be latched
per device at device init. Provide visibility of the per device
latched values through debugfs. (Alex Williamson)
- Fix missing VGA arbiter uninit callback in unwind path.
(Alex Williamson)
- Reorder device debugfs removal before device_del() to avoid gap
where debugfs is available with stale devres pointers.

- Move UUID library linking flag from vfio selftest Makefile into
libvfio.mk to avoid exposing such dependencies when linking with
KVM selftests. (Sean Christopherson)

This SPI controller likely belongs to a power domain for all the SoCs
listed. For sure, it belongs to one on the Renesas RZ/N1 SoC, so
enable the property to be able to describe its power domain in DTs.

Commit 164c05f03f ("spi: Convert DW SPI binding to DT schema") added
an RZ/N1 entry which was not in the original txt-file. It doesn't follow
the usual "<soc entry>, <soc family entry>" style for Renesas SoCs which
was properly added later with commit 029d32a892 ("spi: dw-apb-ssi:
Integrate Renesas RZ/N1 SPI controller"). In that commit, removing the
bogus entry was overlooked and is finally done now.
