- Use correct locking in zPCI event code to avoid deadlock

- Get rid of irqs_registered flag in zpci_dev structure and restore IRQ
unconditionally for zPCI devices. This fixes sit uations where the
flag was not correctly updated

- Fix potential memory leak kernel page table dumper code

- Disable (revert) ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP for s390 again.

The optimized hugetlb vmemmap code modifies kernel page tables in a
way which does not work on s390 and leads to reproducible kernel
crashes due to stale TLB entries. This needs to be addressed with
some larger changes. For now simply disable the feature

Merge patch series "ns: support file handles"

Christian Brauner <brauner@kernel.org> says:

For a while now we have supported file handles for pidfds. This has
proven to be very useful.

Extend the concept to cover namespaces as well. After this patchset it
is possible to encode and decode namespace file handles using the
commong name_to_handle_at() and open_by_handle_at() apis.

Namespaces file descriptors can already be derived from pidfds which
means they aren't subject to overmount protection bugs. IOW, it's
irrelevant if the caller would not have access to an appropriate
/proc/<pid>/ns/ directory as they could always just derive the namespace
based on a pidfd already.

It has the same advantage as pidfds. It's possible to reliably and for
the lifetime of the system refer to a namespace without pinning any
resources and to compare them.

Permission checking is kept simple. If the caller is located in the
namespace the file handle refers to they are able to open it otherwise
they must hold privilege over the owning namespace of the relevant
namespace.

Both the network namespace and the mount namespace already have an
associated cookie that isn't recycled and is fully exposed to userspace.
Move this into ns_common and use the same id space for all namespaces so
they can trivially and reliably be compared.

There's more coming based on the iterator infrastructure but the series
is large enough and focuses on file handles.

Extensive selftests included.

Merge tag 'fix-scrub-reap-calculations_2025-09-05' of https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux into xfs-6.18-merge

xfs: improve online repair reap calculations [6.18 v2 1/2]

A few months ago, the multi-fsblock untorn writes patchset added a bunch
of log intent item helper functions to estimate the number of intent
items that could be added to a particular transaction. Those helpers
enabled us to compute a safe upper bound on the number of blocks that
could be written in an untorn fashion with filesystem-provided out of
place writes.

Currently, the online fsck code employs static limits on the number of
intent items that it's willing to accrue to a single transaction when
it's trying to reap what it thinks are the old blocks from a corrupt
structure. There have been no problems reported with this approach
after years of testing, but static limits are scary and gross because
overestimating the intent item limit could result in transaction
overflows and dead filesystems; and underestimating causes unnecessary
overhead.

This series uses the new log intent item size helpers to estimate the
limits dynamically based on worst-case per-block repair work vs. the
size of the scrub transaction. After several months of testing this,
there don't seem to be any problems here either.

v2: rearrange patches, add review tags

This has been running on the djcloud for months with no problems. Enjoy!

spi: spi-fsl-dspi: Target mode improvements

Merge series from James Clark <james.clark@linaro.org>:

Improve usability of target mode by reporting FIFO errors and increasing
the buffer size when DMA is used. While we're touching DMA stuff also
switch to non-coherent memory, although this is unrelated to target
mode.

With the combination of the commit to increase the DMA buffer size and
the commit to use non-coherent memory, the host mode performance figures
are as follows on S32G3:

# spidev_test --device /dev/spidev1.0 --bpw 8 --size <test_size> --cpha --iter 10000000 --speed 10000000

Coherent (4096 byte transfers): 6534 kbps
Non-coherent: 7347 kbps

Coherent (16 byte transfers): 447 kbps
Non-coherent: 448 kbps

Just for comparison running the same test in XSPI mode:

4096 byte transfers: 2143 kbps
16 byte transfers: 637 kbps

These tests required hacking S32G3 to use DMA in host mode, although
the figures should be representative of target mode too where DMA is
used. And the other devices that use DMA in host mode should see similar
improvements.
