Currently we only display the warning when the instructions group is
requested. Instructions are on by default, and the period applies to all
sample types anyway so always check the options and show the warning.
Reword the messages to be more explicit about which flags the warnings
apply to.

The various sample types that are generated are based on the same SPE
sample, just placed into different sample type bins.
The same sample can be in multiple bins if it has flags set that cause
it to be.
Currently we're only applying the --itrace interval downsampling to the
instruction bin, which means that the sample would appear in one bin but
not another if it was skipped due to downsampling.
I don't thing anyone would want or expect this, so make this behave
consistently by applying the downsampling before generating any sample.
You might argue that the "instructions" interval type doesn't make sense
to apply to "memory" sample types because it would be skipping every n
memory samples, rather than every n instructions.
ut the downsampling was already not an instruction interval even for the
instruction samples. SPE has a hardware based sampling interval, and the
instruction interval was just a convenient way to specify further
downsampling.
This is hinted at in the warning message shown for intervals greater
than 1.
This makes SPE diverge from trace technologies like Intel PT and Arm
Coresight.
In those cases instruction samples can be reduced but all branches are
still emitted. This makes sense there, because branches form a complete
execution history, and asking to skip branches every n instructions
doesn't really make sense.
But for SPE, as mentioned above, downsampling the instruction samples
already wasn't consistent with trace technologies so we ended up with
some middle ground that had no benefit.
Now it's possible to reduce the volume of samples in all groups and
samples won't be missing from one group but present in another.

Instruction sample types are enabled in the default itrace options in
perf, but this never applied to SPE because the default nanoseconds
period isn't supported.
This meant that instructions ended up being opt-in by the user only when
they requested an instruction based period.
Change the default period type to instructions so that instruction
samples are generated by default. This can overridden by specifying any
--itrace option.
This solves a common complaint from users that the unfiltered SPE
samples appear to be missing, and only the samples that have memory
flags set appear in the various memory groups.

Pull vfs fixes from Christian Brauner:
"fuse:
- Prevent opening of non-regular backing files.
Fuse doesn't support non-regular files anyway.
- Check whether copy_file_range() returns a larger size than
requested.
- Prevent overflow in copy_file_range() as fuse currently only
supports 32-bit sized copies.
- Cache the blocksize value if the server returned a new value as
inode->i_blkbits isn't modified directly anymore.
- Fix i_blkbits handling for iomap partial writes.
By default i_blkbits is set to PAGE_SIZE which causes iomap to mark
the whole folio as uptodate even on a partial write. But fuseblk
filesystems support choosing a blocksize smaller than PAGE_SIZE
risking data corruption. Simply enforce PAGE_SIZE as blocksize for
fuseblk's internal inode for now.
- Prevent out-of-bounds acces in fuse_dev_write() when the number of
bytes to be retrieved is truncated to the fc->max_pages limit.
virtiofs:
- Fix page faults for DAX page addresses.
Misc:
- Tighten file handle decoding from userns.
Check that the decoded dentry itself has a valid idmapping in the
user namespace.
- Fix mount-notify selftests.
- Fix some indentation errors.
- Add an FMODE_ flag to indicate IOCB_HAS_METADATA availability.
This will be moved to an FOP_* flag with a bit more rework needed
for that to happen not suitable for a fix.
- Don't silently ignore metadata for sync read/write.
- Don't pointlessly log warning when reading coredump sysctls"

The kexec_buf structure was previously declared without initialization.
commit bf454ec31a ("kexec_file: allow to place kexec_buf randomly")
added a field that is always read but not consistently populated by all
architectures. This un-initialized field will contain garbage.
This is also triggering a UBSAN warning when the uninitialized data was
accessed:
------------[ cut here ]------------
UBSAN: invalid-load in ./include/linux/kexec.h:210:10
load of value 252 is not a valid value for type '_Bool'
Zero-initializing kexec_buf at declaration ensures all fields are
cleanly set, preventing future instances of uninitialized memory being
used.

The type of the value to write should be determined by the size of the
destination, not by the value itself, which may be a constant. This
aligns the behavior with x86_64, where __typeof__(*(__gu_ptr)) is used
to infer the correct type.
This fixes an issue in put_cmsg, which was only writing 4 out of 8
bytes to the cmsg_len field, causing the glibc tst-socket-timestamp test
to fail.

The largest batch of fixes here is a series of fixes for the Freescale
LPSPI driver which James Clark pulled out of their BSP while looking at
support for the NXP S32G version of the controller. The majority of
this turned out to be bug fixes that affect existing systems with the
actual S32G support being just a small quirk that would be unremarkable
by itself, the whole series has had a good amount of testing and review
and the individual patches are all pretty straightforward by themselves.
We also have a few other driver specific fixes, including a relatively
large but simple one for the Cadence QuadSPI driver.

On arm64, it has been possible for a module's sections to be placed more
than 128M away from each other since commit:
commit 3e35d303ab ("arm64: module: rework module VA range selection")
Due to this, an ftrace callsite in a module's .init.text section can be
out of branch range for the module's ftrace PLT entry (in the module's
.text section). Any attempt to enable tracing of that callsite will
result in a BRK being patched into the callsite, resulting in a fatal
exception when the callsite is later executed.
Fix this by adding an additional trampoline for .init.text, which will
be within range.
No additional trampolines are necessary due to the way a given
module's executable sections are packed together. Any executable
section beginning with ".init" will be placed in MOD_INIT_TEXT,
and any other executable section, including those beginning with ".exit",
will be placed in MOD_TEXT.

Fix a regression caused by my commits that reimplemented the sha1,
sha256, and sha512 crypto_shash algorithms on top of the library API.
Specifically, the export_core and import_core methods stopped being
supported, which broke some hardware offload drivers (such as qat)
that recently started depending on these for fallback functionality.
Later I'd like to make these drivers just use the library API for
their fallback. Then these methods won't be needed anymore. But for
now, this fixes the regression for 6.17.

James Clark caught that the BUILD_NONDISTRO=1 build with libbfd was
broken due to an update to the read_build_id function adding a
blocking argument. Add support for this argument by first opening the
file blocking or non-blocking, then switching from bfd_openr to
bfd_fdopenr and passing the opened fd. bfd_fdopenr closes the fd on
error and when bfd_close are called.

commit edf2cadf01 ("perf test: add test for BPF metadata collection")
fails consistently on the version string check. The perf version
string on some of the constant integration test machines contains
characters with special meaning in grep's extended regular expression
matching algorithm. The output of perf version is:
# perf version
perf version 6.17.0-20250814.rc1.git20.24ea63ea3877.63.fc42.s390x+git
#
and the '+' character has special meaning in egrep command.
Also the use of egrep is deprecated.
Change the perf version string check to fixed character matching
and get rid of egrep's warning being deprecated. Use grep -F instead.
Output before:
# perf test -F 102
Checking BPF metadata collection
egrep: warning: egrep is obsolescent; using grep -E
Basic BPF metadata test [Failed invalid output]
102: BPF metadata collection test : FAILED!
#
Output after:
# perf test -F 102

When building with CONFIG_CMODEL_MEDLOW and CONFIG_LTO_CLANG, there is a
series of errors due to some files being unconditionally compiled with
'-mcmodel=medany', mismatching with the rest of the kernel built with
'-mcmodel=medlow':
ld.lld: error: Function Import: link error: linking module flags 'Code Model': IDs have conflicting values: 'i32 3' from vmlinux.a(init.o at 899908), and 'i32 1' from vmlinux.a(net-traces.o at 1014628)
Only allow LTO to be performed when CONFIG_CMODEL_MEDANY is enabled to
ensure there will be no code model mismatch errors. An alternative
solution would be disabling LTO for the files with a different code
model than the main kernel like some specialized areas of the kernel do
but doing that for individual files is not as sustainable than
forbidding the combination altogether.
