13a0d1ae7e iommufd: Do not corrupt the pfn list when doing batch carry
If batch->end is 0 then setting npfns[0] before computing the new value of
pfns will fail to adjust the pfn and result in various page accounting
corruptions. It should be ordered after.

This seems to result in various kinds of page meta-data corruption related
failures:

727c28c1ce iommufd: Fix unpinning of pages when an access is present
syzkaller found that the calculation of batch_last_index should use
'start_index' since at input to this function the batch is either empty or
it has already been adjusted to cross any accesses so it will start at the
point we are unmapping from.

Getting this wrong causes the unmap to run over the end of the pages
which corrupts pages that were never mapped. In most cases this triggers
the num pinned debugging:

b277fc793d powerpc/papr_scm: Update the NUMA distance table for the target node
Platform device helper routines won't update the NUMA distance table
while creating a platform device, even if the device is present on a
NUMA node that doesn't have memory or CPU. This is especially true for
pmem devices. If the target node of the pmem device is not online, we
find the nearest online node to the device and associate the pmem device
with that online node. To find the nearest online node, we should have
the numa distance table updated correctly. Update the distance
information during the device probe.

For a papr scm device on NUMA node 3 distance_lookup_table value for
distance_ref_points_depth = 2 before and after fix is below:

Before fix:
  node 3 distance depth 0  - 0
  node 3 distance depth 1  - 0
  node 4 distance depth 0  - 4
  node 4 distance depth 1  - 2
  node 5 distance depth 0  - 5
  node 5 distance depth 1  - 1

After fix
  node 3 distance depth 0  - 3
  node 3 distance depth 1  - 1
  node 4 distance depth 0  - 4
  node 4 distance depth 1  - 2
  node 5 distance depth 0  - 5
  node 5 distance depth 1  - 1

Without the fix, the nearest numa node to the pmem device (NUMA node 3)
will be picked as 4. After the fix, we get the correct numa node which
is 5.

spi: qup: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

spi: spi-imx: fix MX51_ECSPI_* macros when cs > 3
When using gpio based chip select the cs value can go outside the range
0 – 3. The various MX51_ECSPI_* macros did not take this into consideration
resulting in possible corruption of the configuration.

For example for any cs value over 3 the SCLKPHA bits would not be set and
other values in the register possibly corrupted.

One way to fix this is to just mask the cs bits to 2 bits. This still
allows all 4 native chip selects to work as well as gpio chip selects
(which can use any of the 4 chip select configurations).

ASoC: SOF: Intel: hda: make DSPless mode work with DSP disabled in BIOS
When the DSP is disabled in the BIOS, the DSP_BAR and PP_BAR cannot be
accessed.

One possible objection noted in initial reviews is that this patch
adds a number of branches. However the number of branches is actually
limited in probe/suspend/resume routines mostly, so there isn't really
a degradation in terms of readability and maintainability. Adding yet
another level of abstraction/ops/callbacks would increase complexity
and not really help in terms of code reuse or readability and
maintainability. A split between controller and DSP driver would be
even more invasive.

still needed on existing platforms for SSP, DMIC, SoundWire interfaces
managed by the GP-DMA.

This mode is also helpful to compare the legacy HDaudio driver with the

b103bab094 Merge branch 'vsock-return-errors-other-than-enomem-to-socket'
Arseniy Krasnov says:

====================
vsock: return errors other than -ENOMEM to socket

this patchset removes behaviour, where error code returned from any
transport was always switched to ENOMEM. This works in the same way as
patch from Bobby Eshleman:
commit c43170b7e1 ("vsock: return errors other than -ENOMEM to socket"),
but for receive calls. VMCI transport is also updated (both tx and rx
SOCK_STREAM callbacks), because it returns VMCI specific error code to
af_vsock.c (like VMCI_ERROR_*). Tx path is already merged to net, so it
was excluded from patchset in v4. At the same time, virtio and Hyper-V
transports are using general error codes, so there is no need to update
them.

vsock_test suite is also updated.

c6b486fb33 net: ethernet: ti: am65-cpsw: Fix mdio cleanup in probe
In the am65_cpsw_nuss_probe() function's cleanup path, the call to
of_platform_device_destroy() for the common->mdio_dev device is invoked
unconditionally. It is possible that either the MDIO node is not present
in the device-tree, or the MDIO node is disabled in the device-tree. In
both these cases, the MDIO device is not created, resulting in a NULL
pointer dereference when the of_platform_device_destroy() function is
invoked on the common->mdio_dev device on the cleanup path.

Fix this by ensuring that the common->mdio_dev device exists, before
attempting to invoke of_platform_device_destroy().

a3046a618a um: Only disable SSE on clang to work around old GCC bugs
As part of the Rust support for UML, we disable SSE (and similar flags)
to match the normal x86 builds. This both makes sense (we ideally want a
similar configuration to x86), and works around a crash bug with SSE
generation under Rust with LLVM.

However, this breaks compiling stdlib.h under gcc < 11, as the x86_64
ABI requires floating-point return values be stored in an SSE register.
gcc 11 fixes this by only doing register allocation when a function is
actually used, and since we never use atof(), it shouldn't be a problem:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99652

Nevertheless, only disable SSE on clang setups, as that's a simple way
of working around everyone's bugs.
