17354d1528 perf test: Simplify for_each_test() to avoid tripping on -Werror=array-bounds
When cross building on debian to the mips 32-bit arch we get these

Switch to using a while(!sentinel) for the second level of the 'tests'
array to avoid that compiler complaint.

783ae448b7 ext4: Fix special handling of journalled data from extent zeroing
The handling of journalled data in ext4_zero_range() is incomplete. We
do not need to commit running transaction but we rather need to
checkpoint pages with journalled data. If we don't, journal tail can be
advanced beyond transaction containing the journalled data and if we
then crash before committing the transaction doing the zeroing we will
have inconsistent (too old) data in the file. Make sure file pages with
journalled data are properly checkpointed before removing them from the
page cache.

1f1a55f0bf ext4: Commit transaction before writing back pages in data=journal mode
When journalling data we currently just walk over pages, journal those
that are marked for delayed dirtying (only pinned pages dirtied behing
our back these days) and checkpoint other dirty pages. Because some
pages may be part of running transaction the result is that after
filemap_write_and_wait() we are not guaranteed pages are stable on disk.
Thus places that want to flush current pagecache content need to jump
through hoops to make sure journalled data is not lost. This is
manageable in cases completely controlled by ext4 (such as extent
shifting operations or inode eviction) but it gets ugly for stuff like
fsverity. Furthermore it is rather error prone as people often do not
realize journalled data needs special handling.

So change ext4_writepages() to commit transaction with inode's data
before going through the writeback loop in WB_SYNC_ALL mode. As a result
filemap_write_and_wait() is now really getting pages to stable storage
and makes pagecache pages safe to reclaim. Consequently we can remove
the special handling of journalled data from several places in follow up
patches.

Note that this will make fsync(2) for journalled data more expensive as
we will end up not only committing the transaction we need but also
checkpointing the data (which we may have previously skipped if the data
was part of the running transaction). If we really cared, we would need
to introduce special VFS function for writing out & invalidating page
cache for a range, use ->launder_page callback to perform checkpointing,
and use it from all the places that need this functionality. But at this
point I'm not convinced the complexity is worth it.

5e1bdea639 ext4: Clear dirty bit from pages without data to write
With journalled data it can happen that checkpointing code will write
out page contents without clearing the page dirty bit. The logic in
ext4_page_nomap_can_writeout() then results in us never calling
mpage_submit_page() and thus clearing the dirty bit. Drop the
optimization with ext4_page_nomap_can_writeout() and just always call to
mpage_submit_page(). ext4_bio_write_page() knows when to redirty the
page and the additional clearing & setting of page dirty bit for ordered
mode writeout is not that expensive to jump through the hoops for it.

265e72efa9 ext4: Keep pages with journalled data dirty
Currently we clear page dirty bit when we checkpoint some buffers from a
page with journalled data or when we perform delayed dirtying of a page
in ext4_writepages(). In a quest to simplify handling of journalled data
we want to keep page dirty as long as it has either buffers to
checkpoint or journalled dirty data. So make sure to keep page dirty in
ext4_writepages() if it still has journalled data attached to it.

d84c9ebdac ext4: Mark pages with journalled data dirty
Currently pages with journalled data written by write(2) or modified by
block zeroing during truncate(2) are not marked as dirty. They are
dirtied only once the transaction commits. This however makes writeback
code think inode has no pages to write and so ext4_writepages() is not
called to make pages with journalled data persistent. Mark pages with
journalled data dirty (similarly as it happens for writes through mmap)
so that writeback code knows about them and ext4_writepages() can do
what it needs to to the inode.

bd159398a2 jdb2: Don't refuse invalidation of already invalidated buffers
When invalidating buffers under the partial tail page,
jbd2_journal_invalidate_folio() returns -EBUSY if the buffer is part of
the committing transaction as we cannot safely modify buffer state.
However if the buffer is already invalidated (due to previous
invalidation attempts from ext4_wait_for_tail_page_commit()), there's
nothing to do and there's no point in returning -EBUSY. This fixes
occasional warnings from ext4_journalled_invalidate_folio() triggered by
generic/051 fstest when blocksize < pagesize.

17dc71c336 net/mlx5: DR, Fix QP continuous allocation
When allocating a QP we allocate an RQ and an SQ, the RQ is stored first
in memory and followed by the SQ.
This allocation is not physically continiuos - it may span across different
physical pages. SW Steering code always writes in pairs: 1BB write + 1BB read,
or 2 continuous BBs of GTA WQE.

This lead to an issue where RQ allocation was 4x16 which is equal to 1 WQE BB,
causing 1 BB offset in the page and splitting the GTA WQE between different
physical pages.

The solution was to create the RQ with a even number of BBs and to have the
RQ aligned to a page.

7d7c9453d6 net/mlx5: DR, Read ICM memory into dedicated buffer
Instead of using the write buffer for reading we will use a dedicated
buffer only for reading ICM memory.
Due to the new support for args, we can have a case with pending_wc
being odd number, and with reading into the same write buffer, it is
possible to overwrite next write on the same slot.
For example:
pending_wc is 17 so the buffer for write is:
   | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
and we have requests as follows:
   r wr wr wr wr wr wr wr wr
Now, the first read will be written into the last write because we use
the same buffer for read and write, before it was written to the HW and
we will have a wrong data in the ICM area.

457bd7af1a KVM: selftests: Test the PMU event "Instructions retired"
Add testing for the event "Instructions retired" (0xc0) in the PMU
event filter on both Intel and AMD to ensure that the event doesn't
count when it is disallowed.  Unlike most of the other events, the
event "Instructions retired" will be incremented by KVM when an
instruction is emulated.  Test that this case is being properly handled
and that KVM doesn't increment the counter when that event is
disallowed.

e9f322bd23 KVM: selftests: Copy full counter values from guest in PMU event filter test
Use a single struct to track all PMC event counts in the PMU filter test,
and copy the full struct to/from the guest when running and measuring each
guest workload.  Using a common struct avoids naming conflicts, e.g. the
loads/stores testcase has claimed "perf_counter", and eliminates the
unnecessary truncation of the counter values when they are propagated from
the guest MSRs to the host structs.

Zero the struct before running the guest workload to ensure that the test
doesn't get a false pass due to consuming data from a previous run.

c02c744282 KVM: selftests: Use error codes to signal errors in PMU event filter test
Use '0' to signal success and '-errno' to signal failure in the PMU event
filter test so that the values are slightly less magical/arbitrary.  Using
'0' in the error paths is especially confusing as understanding it's an
error value requires following the breadcrumbs to the host code that
ultimately consumes the value.

Arguably there should also be a #define for "success", but 0/-errno is a
common enough pattern that defining another macro on top would likely do
more harm than good.

6467d0740a vfio/pci: Add DVSEC PCI Extended Config Capability to user visible list.
The Designated Vendor-Specific Extended Capability (DVSEC Capability) is an
optional Extended Capability that is permitted to be implemented by any PCI
Express Function. This allows PCI Express component vendors to use
the Extended Capability mechanism to expose vendor-specific registers that can
be present in components by a variety of vendors. A DVSEC Capability structure
can tell vendor-specific software which features a particular component
supports.

An example usage of DVSEC is Intel Platform Monitoring Technology (PMT) for
enumerating and accessing hardware monitoring capabilities on a device.
PMT encompasses three device monitoring features, Telemetry (device metrics),
Watcher (sampling/tracing), and Crashlog. The DVSEC is used to discover these
features and provide a BAR offset to their registers with the Intel vendor code.

The current VFIO driver does not pass DVSEC capabilities to Virtual Machine (VM)
which makes PMT not to work inside the virtual machine. This series adds DVSEC
capability to user visible list to allow its use with VFIO. VFIO supports
passing of Vendor Specific Extended Capability (VSEC) and raw write access to
device. DVSEC also passed to VM in the same way as of VSEC.

8368877140 drm/amdkfd: Enable HW_UPDATE_RPTR on GC 9.4.3
GC 9.4.3 uses the hardware to update AQL queues read pointer, so
remove CP_HQD_PQ_CONTROL__NO_UPDATE_RPTR_MASK flag from MQD if it's
GC 9.4.3, and keep it for other existing gfx9 ASICs.
