Use LZMA2 options that match the arch-specific alignment of instructions.
This change reduces compressed kernel size 0-2 % depending on the arch.
On 1-byte-aligned x86 it makes no difference and on 4-byte-aligned archs
it helps the most.
Use the ARM-Thumb filter for ARM-Thumb2 kernels. This reduces compressed
kernel size about 5 %.[1] Previously such kernels were compressed using
the ARM filter which didn't do anything useful with ARM-Thumb2 code.
Add BCJ filter support for ARM64 and RISC-V. Compared to unfiltered XZ or
plain LZMA, the compressed kernel size is reduced about 5 % on ARM64 and 7
% on RISC-V. A new enough version of the xz tool is required: 5.4.0 for
ARM64 and 5.6.0 for RISC-V. With an old xz version, a message is printed
to standard error and the kernel is compressed without the filter.
Update lib/decompress_unxz.c to match the changes to xz_wrap.sh.
Update the CONFIG_KERNEL_XZ help text in init/Kconfig:
- Add the RISC-V and ARM64 filters.
- Clarify that the PowerPC filter is for big endian only.
- Omit IA-64.

This only affects kernel image compression, not any other xz usage.
Desktop kernels on x86-64 are already around 60 MiB. Using a dictionary
larger than 32 MiB should have no downsides nowadays as anyone building
the kernel should have plenty of RAM. 128 MiB dictionary needs 1346 MiB
of RAM with xz versions 5.0.x - 5.6.x in single-threaded mode. On archs
that use xz_wrap.sh, kernel decompression is done in single-call mode so a
larger dictionary doesn't affect boot-time memory requirements.
xz >= 5.6.0 uses multithreaded mode by default which compresses slightly
worse than single-threaded mode. Kernel compression rarely used more than
one thread anyway because with 32 MiB dictionary size the default block
size was 96 MiB in multithreaded mode. So only a single thread was used
anyway unless the kernel was over 96 MiB.
Comparison to CONFIG_KERNEL_LZMA: It uses "lzma -9" which mapped to 32 MiB
dictionary in LZMA Utils 4.32.7 (the final release in 2008). Nowadays the
lzma tool on most systems is from XZ Utils where -9 maps to 64 MiB
dictionary. So using a 32 MiB dictionary with CONFIG_KERNEL_XZ may have
compressed big kernels slightly worse than the old LZMA option.
Comparison to CONFIG_KERNEL_ZSTD: zstd uses 128 MiB dictionary.

duplicating the same constant in multiple files. Two months later it was
found to be a bad idea and the definition of CRC32_POLY_LE macro was moved
into xz_private.h to avoid including <linux/crc32poly.h>.
xz_private.h is a wrong place for it too. Revert back to the upstream

Patch series "xz: Updates to license, filters, and compression options",
v2.
XZ Embedded, the upstream project, switched from public domain to the BSD
Zero Clause License (0BSD). Now matching SPDX license identifiers can be
added.
Documentation was revised. Fix syntax errors in kernel-doc comments in
<linux/xz.h>. The xz_dec API docs from <linux/xz.h> are now included in
Documentation/staging/xz.rst.
The new ARM64 and RISC-V filters can be used for kernel decompression if
CONFIG_EFI_ZBOOT=y. The filters can be used by Squashfs too. (Userspace
Squashfs-tools already had the ARM64 filter support committed but it was
reverted due to backdoor fears. I try to get ARM64 and RISC-V filter
support added to Squashfs-tools somewhat soon.)
Account for the default threading change made in the xz command line tool
version 5.6.0. Tweak kernel compression options for archs that support XZ
compressed kernel.
This patch (of 16):
I have been the maintainer of the upstream project since I submitted the
code to Linux in 2010 but I forgot to add myself to MAINTAINERS.

This bug has existed since the initial OCFS2 code. The code logic in
ocfs2_sync_local_to_main() is wrong, as it ignores the last contiguous
free bits, which causes an OCFS2 volume to lose the last free clusters of
LA window on each umount command.

Patch series "mul_u64_u64_div_u64: new implementation", v3.
This provides an implementation for mul_u64_u64_div_u64() that always
produces exact results.
This patch (of 2):
Library facilities must always return exact results. If the caller may be
contented with approximations then it should do the approximation on its
own.
In this particular case the comment in the code says "the algorithm
... below might lose some precision". Well, if you try it with e.g.:
a = 18446462598732840960
b = 18446462598732840960
c = 18446462598732840961
then the produced answer is 0 whereas the exact answer should be
18446462598732840959. This is _some_ precision lost indeed!
Let's reimplement this function so it always produces the exact result
regardless of its inputs while preserving existing fast paths when
possible.
Uwe said:
: My personal interest is to get the calculations in pwm drivers right.
: This function is used in several drivers below drivers/pwm/ . With the
: errors in mul_u64_u64_div_u64(), pwm consumers might not get the
: settings they request. Although I have to admit that I'm not aware it
: breaks real use cases (because typically the periods used are too short
: to make the involved multiplications overflow), but I pretty sure am
: not aware of all usages and it breaks testing.

: Another justification is commits like

: where people start to work around the precision shortcomings of

We had a report of data corruption on nixos when building installer
images.
https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334
It seems that writes are being dropped, but only when issued by QEMU,
and possibly only in snapshot mode. It's undetermined if it's write
calls are being dropped or dirty folios.
Further testing, via minimizing the original patch to just the change
that skips the inode lock on non appends/truncates, reveals that it
really is just not taking the inode lock that causes the corruption: it
has nothing to do with the other logic changes for preserving write
atomicity in corner cases.
It's also kernel config dependent: it doesn't reproduce with the minimal
kernel config that ktest uses, but it does reproduce with nixos's distro
config. Bisection the kernel config initially pointer the finger at page
migration or compaction, but it appears that was erroneous; we haven't
yet determined what kernel config option actually triggers it.
Sadly it appears this will have to be reverted since we're getting too
close to release and my plate is full, but we'd _really_ like to fully
debug it.
My suspicion is that this patch is exposing a preexisting bug - the
inode lock actually covers very little in IO paths, and we have a
different lock (the pagecache add lock) that guards against races with
truncate here.

There is a fairly large number of bug fixes for Qualcomm platforms,
most of them addressing issues with the devicetree files for the
newly added Snapdragon X1 based laptops to make them more reliable.
The Qualcomm driver changes address a few build-time issues as well
as runtime problems in the tzmem and scm firmware, the USB Type-C
driver, and the cmd-db and pmic_glink soc drivers.
The NXP i.MX usually gets a bunch of devicetree fixes that is proportional
to the number of supported machines. This includes both warning fixes
and correctness for the 64-bit i.MX9, i.MX8 and layerscape platforms,
as well as a single fix for a 32-bit i.MX6 based board.
The other changes are the usual minor changes, including an update to the
MAINTAINERS file, an omap3 dts file and a SoC driver for mpfs (risc-v).

copying of iovecs for compat mode applications got broken for certain

- Fix for a bug introduced in 6.10, where if using recv/send bundles

io_provided_buffers_select() returns 0 to indicate success, but it should
be returning 1 to indicate that 1 vec was mapped. This causes peeking
to fail with classic provided buffers, and while that's not a use case
that anyone should use, it should still work correctly.
The end result is that no buffer will be selected, and hence a completion
with '0' as the result will be posted, without a buffer attached.

It is not safe to dereference fl->c.flc_owner without first confirming
fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict()
tests fl_lmops but largely ignores the result and assumes that flc_owner
is an nfs4_delegation anyway. This is wrong.
With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave
as it did before the change mentioned below. This is the same as the
current code, but without any reference to a possible delegation.

For buffer registration (or updates), a userspace iovec is copied in
and updated. If the application is within a compat syscall, then the
iovec type is compat_iovec rather than iovec. However, the type used
in __io_sqe_buffers_update() and io_sqe_buffers_register() is always
struct iovec, and hence the source is incremented by the size of a
non-compat iovec in the loop. This misses every other iovec in the
source, and will run into garbage half way through the copies and
return -EFAULT to the application.
Maintain the source address separately and assign to our user vec
pointer, so that copies always happen from the right source address.
While in there, correct a bad placement of __user which triggered
the following sparse warning prior to this fix:
io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression
io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces)
io_uring/rsrc.c:981:30: expected struct iovec const [noderef] __user *uvec
