Pavel Begunkov f36ba6cf1a io_uring: don't iterate cq wait fast path
Task work runners keep running until all queues tw items are exhausted.
It's also rare for defer tw to queue normal tw and vise versa. Taking it
into account, there is only a dim chance that further iterating the
io_cqring_wait() fast path will get us anything and so we can remove
the loop there.

Pavel Begunkov 0c4fe008c9 io_uring: rearrange defer list checks
There should be nothing in the ->work_llist for non DEFER_TASKRUN rings,
so we can skip flag checks and test the list emptiness directly. Also
move it out of io_run_local_work() for inlining.

Only Stage1 Page table walks (S1PTW) trying to write into a PTE should
result in the PTE page being dirty in the log.  However, the dirty log
tests in page_fault_test default to treat all S1PTW accesses as writes.
Fix the relevant tests by asserting dirty pages only for S1PTW writes,
which in these tests only applies to when Hardware management of the Access
Flag is enabled.

Ricardo Koller 0dd8d22a88 KVM: selftests: aarch64: Relax userfaultfd read vs. write checks
Only Stage1 Page table walks (S1PTW) writing a PTE on an unmapped page
should result in a userfaultfd write. However, the userfaultfd tests in
page_fault_test wrongly assert that any S1PTW is a PTE write.

Fix this by relaxing the read vs. write checks in all userfaultfd
handlers.  Note that this is also an attempt to focus less on KVM (and
userfaultfd) behavior, and more on architectural behavior. Also note
that after commit 406504c7b0 ("KVM: arm64: Fix S1PTW handling on RO
memslots"), the userfaultfd fault (S1PTW with AF on an unmaped PTE
page) is actually a read: the translation fault that comes before the
permission fault.

Gavin Shan a23eaf9368 KVM: arm64: Add helper vgic_write_guest_lock()
Currently, the unknown no-running-vcpu sites are reported when a
dirty page is tracked by mark_page_dirty_in_slot(). Until now, the
only known no-running-vcpu site is saving vgic/its tables through
KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_SAVE_TABLES} command on KVM device
"kvm-arm-vgic-its". Unfortunately, there are more unknown sites to
be handled and no-running-vcpu context will be allowed in these
sites: (1) KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_RESTORE_TABLES} command
on KVM device "kvm-arm-vgic-its" to restore vgic/its tables. The
vgic3 LPI pending status could be restored. (2) Save vgic3 pending
table through KVM_DEV_ARM_{VGIC_GRP_CTRL, VGIC_SAVE_PENDING_TABLES}
command on KVM device "kvm-arm-vgic-v3".

In order to handle those unknown cases, we need a unified helper
vgic_write_guest_lock(). struct vgic_dist::save_its_tables_in_progress
is also renamed to struct vgic_dist::save_tables_in_progress.

No functional change intended.

Vlastimil Babka 95e7a450b8 Revert "mm/compaction: fix set skip in fast_find_migrateblock"
This reverts commit 7efc3b7261.

We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged
stalling CPU for long periods of time.  Investigation of tracepoint data
shows that compaction is stuck in repeating fast_find_migrateblock()
based migrate page isolation, and then fails to migrate all isolated
pages.

Commit 7efc3b7261 ("mm/compaction: fix set skip in fast_find_migrateblock")
was suspected as it was merged in 6.1 and in theory can indeed remove a
termination condition for fast_find_migrateblock() under certain
conditions, as it removes a place that always marks a scanned pageblock
from being re-scanned.  There are other such places, but those can be
skipped under certain conditions, which seems to match the tracepoint
data.

Testing of revert also appears to have resolved the issue, thus revert
the commit until a more robust solution for the original problem is
developed.

It's also likely this will fix qemu stalls with 6.1 kernel reported in
Link 2, but that is not yet confirmed.

Nikita Zhandarovich 5d9745cead RDMA/irdma: Fix potential NULL-ptr-dereference
in_dev_get() can return NULL which will cause a failure once idev is
dereferenced in in_dev_for_each_ifa_rtnl(). This patch adds a
check for NULL value in idev beforehand.

With module and carrier board topology, carrier board dts will include
module dtsi files for creating complete platform.

The carrier board dts will have final model name and compatible string
so any model name added in module dtsi will eventually replaced.

This happened for any devicetree property if the same property is updated
or added twice.

So, drop this unneeded model name from module dtsi.

Dan Williams c91d713630 nvdimm: Support sizeof(struct page) > MAX_STRUCT_PAGE_SIZE
Commit 6e9f05dc66 ("libnvdimm/pfn_dev: increase MAX_STRUCT_PAGE_SIZE")

...updated MAX_STRUCT_PAGE_SIZE to account for sizeof(struct page)
potentially doubling in the case of CONFIG_KMSAN=y. Unfortunately this
doubles the amount of capacity stolen from user addressable capacity for
everyone, regardless of whether they are using the debug option. Revert
that change, mandate that MAX_STRUCT_PAGE_SIZE never exceed 64, but
allow for debug scenarios to proceed with creating debug sized page maps
with a compile option to support debug scenarios.

Note that this only applies to cases where the page map is permanent,
i.e. stored in a reservation of the pmem itself ("--map=dev" in "ndctl
create-namespace" terms). For the "--map=mem" case, since the allocation
is ephemeral for the lifespan of the namespace, there are no explicit
restriction. However, the implicit restriction, of having enough
available "System RAM" to store the page map for the typically large
pmem, still applies.

Eric Biggers 51e4e3153e fscrypt: support decrypting data from large folios
Try to make the filesystem-level decryption functions in fs/crypto/
aware of large folios.  This includes making fscrypt_decrypt_bio()
support the case where the bio contains large folios, and making
fscrypt_decrypt_pagecache_blocks() take a folio instead of a page.

There's no way to actually test this with large folios yet, but I've
tested that this doesn't cause any regressions.

Note that this patch just handles *decryption*, not encryption which
will be a little more difficult.

Ilya Leoshkevich 49f67f393f bpf: btf: Add BTF_FMODEL_SIGNED_ARG flag
s390x eBPF JIT needs to know whether a function return value is signed
and which function arguments are signed, in order to generate code
compliant with the s390x ABI.
