21a9ab5b90 ALSA: usb-audio: Add native DSD quirks for PureAudio DAC series
The PureAudio APA DAC and Lotus DAC5 series are USB Audio
2.0 Class devices that support native Direct Stream Digital (DSD)
playback via specific vendor protocols.

Without these quirks, the devices may only function in standard
PCM mode, or fail to correctly report their DSD format capabilities
to the ALSA framework, preventing native DSD playback under Linux.

This commit adds new quirk entries for the mentioned DAC models
based on their respective Vendor/Product IDs (VID:PID), for example:
0x16d0:0x0ab1 (APA DAC), 0x16d0:0xeca1 (DAC5 series), etc.

The quirk ensures correct DSD format handling by setting the required
SNDRV_PCM_FMTBIT_DSD_U32_BE format bit and defining the DSD-specific
Audio Class 2.0 (AC2.0) endpoint configurations. This allows the ALSA
DSD API to correctly address the device for high-bitrate DSD streams,
bypassing the need for DoP (DSD over PCM).

Test on APA DAC and Lotus DAC5 SE under Arch Linux.

cbcff934fa mm/slub: fix memory leak in free_to_pcs_bulk()
The commit 989b09b739 ("slab: skip percpu sheaves for remote object
freeing") introduced the remote_objects array in free_to_pcs_bulk() to
skip sheaves when objects from a remote node are freed.

However, the array is flushed only when:
  1) the array becomes full (++remote_nr >= PCS_BATCH_MAX), or
  2) slab_free_hook() returns false and size becomes zero.

When neither of the conditions is met, objects in the array are leaked.
This resulted in a memory leak [1], where 82 GiB of memory was allocated
for the maple_node cache.

Flush the array after successfully freeing objects to sheaves
in the do_free: path.

In the meantime, move the snippet if (!size) goto flush_remote; outside
the while loop for readability. Let's say all objects in the array are
from a remote node: then we acquire s->cpu_sheaves->lock and try to free
an object even when size is zero. This doesn't appear to be harmful,
but isn't really readable.

94909c53e4 Merge branch 'hsr-send-correct-hsrv0-supervision-frames'
Felix Maurer says:

====================
hsr: Send correct HSRv0 supervision frames

Hangbin recently reported that the hsr selftests were failing and noted
that the entries in the node table were not merged, i.e., had
00:00:00:00:00:00 as MacAddressB forever [1].

This failure only occured with HSRv0 because it was not sending
supervision frames anymore. While debugging this I found that we were
not really following the HSRv0 standard for the supervision frames we
sent, so I additionally made a few changes to get closer to the standard
and restore a more correct behavior we had a while ago.

The selftests can still fail because they take a while and run into the
timeout. I did not include a change of the timeout because I have more
improvements to the selftests mostly ready that change the test duration
but are net-next material.

b2c26c82f7 hsr: Follow standard for HSRv0 supervision frames
For HSRv0, the path_id has the following meaning:
- 0000: PRP supervision frame
- 0001-1001: HSR ring identifier
- 1010-1011: Frames from PRP network (A/B, with RedBoxes)
- 1111: HSR supervision frame

Follow the IEC 62439-3:2010 standard more closely by setting the right
path_id for HSRv0 supervision frames (actually, it is correctly set when
the frame is constructed, but hsr_set_path_id() overwrites it) and set a
fixed HSR ring identifier of 1. The ring identifier seems to be generally
unused and we ignore it anyways on reception, but some fixed identifier is
definitely better than using one identifier in one direction and a wrong
identifier in the other.

This was also the behavior before commit f266a683a4 ("net/hsr: Better
frame dispatch") which introduced the alternating path_id. This was later
moved to hsr_set_path_id() in commit 451d8123f8 ("net: prp: add packet
handling support").

The IEC 62439-3:2010 also contains 6 unused bytes after the MacAddressA in
the HSRv0 supervision frames. Adjust a TODO comment accordingly.

96a3a03abf hsr: Fix supervision frame sending on HSRv0
On HSRv0, no supervision frames were sent. The supervison frames were
generated successfully, but failed the check for a sufficiently long mac
header, i.e., at least sizeof(struct hsr_ethhdr), in hsr_fill_frame_info()
because the mac header only contained the ethernet header.

Fix this by including the HSR header in the mac header when generating HSR
supervision frames. Note that the mac header now also includes the TLV
fields. This matches how we set the headers on rx and also the size of
struct hsrv0_ethhdr_sp.

0eff2eaa53 virtio-net: fix incorrect flags recording in big mode
The purpose of commit 703eec1b24 ("virtio_net: fixing XDP for fully
checksummed packets handling") is to record the flags in advance, as
their value may be overwritten in the XDP case. However, the flags
recorded under big mode are incorrect, because in big mode, the passed
buf does not point to the rx buffer, but rather to the page of the
submitted buffer. This commit fixes this issue.

For the small mode, the commit c11a49d58a ("virtio_net: Fix mismatched
buf address when unmapping for small packets") fixed it.

214291cbaa acpi/hmat: Fix lockdep warning for hmem_register_resource()
The following lockdep splat was observed while kernel auto-online a CXL
memory region:

======================================================
WARNING: possible circular locking dependency detected
6.17.0djtest+ #53 Tainted: G        W
------------------------------------------------------
systemd-udevd/3334 is trying to acquire lock:
ffffffff90346188 (hmem_resource_lock){+.+.}-{4:4}, at: hmem_register_resource+0x31/0x50

but task is already holding lock:
ffffffff90338890 ((node_chain).rwsem){++++}-{4:4}, at: blocking_notifier_call_chain+0x2e/0x70

which lock already depends on the new lock.
[..]
Chain exists of:
  hmem_resource_lock --> mem_hotplug_lock --> (node_chain).rwsem

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  rlock((node_chain).rwsem);
                               lock(mem_hotplug_lock);
                               lock((node_chain).rwsem);
  lock(hmem_resource_lock);

The lock ordering can cause potential deadlock. There are instances
where hmem_resource_lock is taken after (node_chain).rwsem, and vice
versa.

Split out the target update section of hmat_register_target() so that
hmat_callback() only envokes that section instead of attempt to register
hmem devices that it does not need to.

c55a8e24cd hwmon: (gpd-fan) initialize EC on driver load for Win 4
The original implement will re-init the EC when it reports a zero
value, and it's a workaround for the black box buggy firmware.

Now a contributer test and report that, the bug is that, the firmware
won't initialize the EC on boot, so the EC ramains in unusable status.
And it won't need to re-init it during runtime. The original implement
is not perfect, any write command will be ignored until we first read
it. Just re-init it unconditionally when the driver load could work.

Commit ac4e04d9e3 ("cpufreq: intel_pstate: Unchecked MSR aceess in
legacy mode") introduced a check for feature X86_FEATURE_IDA to verify
turbo mode support. Although this is the correct way to check for turbo
mode support, it causes issues on some platforms that disable turbo
during OS boot, but enable it later [1]. Before adding this feature
check, users were able to get turbo mode frequencies by writing 0 to
/sys/devices/system/cpu/intel_pstate/no_turbo post-boot.

To restore the old behavior on the affected systems while still
addressing the unchecked MSR issue on some Skylake-X systems, check
X86_FEATURE_IDA only immediately before updates of MSR_IA32_PERF_CTL
that may involve setting the Turbo Engage Bit (bit 32).

2d0e88f3fd io_uring/rsrc: don't use blk_rq_nr_phys_segments() as number of bvecs
io_buffer_register_bvec() currently uses blk_rq_nr_phys_segments() as
the number of bvecs in the request. However, bvecs may be split into
multiple segments depending on the queue limits. Thus, the number of
segments may overestimate the number of bvecs. For ublk devices, the
only current users of io_buffer_register_bvec(), virt_boundary_mask,
seg_boundary_mask, max_segments, and max_segment_size can all be set
arbitrarily by the ublk server process.
Set imu->nr_bvecs based on the number of bvecs the rq_for_each_bvec()
loop actually yields. However, continue using blk_rq_nr_phys_segments()
as an upper bound on the number of bvecs when allocating imu to avoid
needing to iterate the bvecs a second time.

d323ad7396 vfio: selftests: replace iova=vaddr with allocated iovas
vfio_dma_mapping_test and vfio_pci_driver_test currently use iova=vaddr
as part of DMA mapping operations. However, not all IOMMUs support the
same virtual address width as the processor. For instance, older Intel
consumer platforms only support 39-bits of IOMMU address space. On such
platforms, using the virtual address as the IOVA fails.

Make the tests more robust by using iova_allocator to vend IOVAs, which
queries legally accessible IOVAs from the underlying IOMMUFD or VFIO
container.

ce0e3c403e vfio: selftests: add iova allocator
Add struct iova_allocator, which gives tests a convenient way to generate
legally-accessible IOVAs to map. This allocator traverses the sorted
available IOVA ranges linearly, requires power-of-two size allocations,
and does not support freeing iova allocations. The assumption is that
tests are not IOVA space-bounded, and will not need to recycle IOVAs.

This is based on Alex Williamson's patch series for adding an IOVA
allocator [1].

a77fa0b922 vfio: selftests: fix map limit tests to use last available iova
Use the newly available vfio_pci_iova_ranges() to determine the last
legal IOVA, and use this as the basis for vfio_dma_map_limit_test tests.

7c44656ab3 vfio: selftests: add iova range query helpers
VFIO selftests need to map IOVAs from legally accessible ranges, which
could vary between hardware. Tests in vfio_dma_mapping_test.c are making
excessively strong assumptions about which IOVAs can be mapped.

Add vfio_iommu_iova_ranges(), which queries IOVA ranges from the
IOMMUFD or VFIO container associated with the device. The queried ranges
are normalized to IOMMUFD's iommu_iova_range representation so that
handling of IOVA ranges up the stack can be implementation-agnostic.
iommu_iova_range and vfio_iova_range are equivalent, so bias to using the
new interface's struct.

Query IOMMUFD's ranges with IOMMU_IOAS_IOVA_RANGES.
Query VFIO container's ranges with VFIO_IOMMU_GET_INFO and
VFIO_IOMMU_TYPE1_INFO_CAP_IOVA_RANGE.

The underlying vfio_iommu_type1_info buffer-related functionality has
been kept generic so the same helpers can be used to query other
capability chain information, if needed.
