Merge tag 'zstd-linus-v6.15-rc1' of https://github.com/terrelln/linux

Pull zstd updates from Nick Terrell:
"Update zstd to the latest upstream release v1.5.7.

The two major motivations for updating Zstandard are to keep the code
up to date, and to expose API's needed by Intel for the QAT
compression accelerator.

Imported cleanly from the upstream tag v1.5.7-kernel, which is signed
by upstream's signing key EF8FE99528B52FFD"

zstd: Import upstream v1.5.7

In addition to keeping the kernel's copy of zstd up to date, this update
was requested by Intel to expose upstream's APIs that allow QAT to accelerate
the LZ match finding stage of Zstd.

This patch is imported from the upstream tag v1.5.7-kernel [0], which is signed
with upstream's signing key EF8FE99528B52FFD [1]. It was imported from upstream
using this command:

export ZSTD=/path/to/repo/zstd/
export LINUX=/path/to/repo/linux/
cd "$ZSTD/contrib/linux-kernel"
git checkout v1.5.7-kernel
make import LINUX="$LINUX"

This patch has been tested on x86-64, and has been boot tested with
a zstd compressed kernel & initramfs on i386 and aarch64. I benchmarked
the patch on x86-64 with gcc-14.2.1 on an Intel i9-9900K by measruing the
performance of compressed filesystem reads and writes.

Component, Level, Size delta, C. time delta, D. time delta
Btrfs , 1, +0.00%, -6.1%, +1.4%
Btrfs , 3, +0.00%, -9.8%, +3.0%
Btrfs , 5, +0.00%, +1.7%, +1.4%
Btrfs , 7, +0.00%, -1.9%, +2.7%
Btrfs , 9, +0.00%, -3.4%, +3.7%
Btrfs , 15, +0.00%, -0.3%, +3.6%
SquashFS , 1, +0.00%, N/A, +1.9%

The major changes that impact the kernel use cases for each version are:

v1.5.7: https://github.com/facebook/zstd/releases/tag/v1.5.7
* Add zstd_compress_sequences_and_literals() for use by Intel's QAT driver
to implement Zstd compression acceleration in the kernel.
* Fix an underflow bug in 32-bit builds that can cause data corruption when
processing more than 4GB of data with a single `ZSTD_CCtx` object, when an
input crosses the 4GB boundry. I don't believe this impacts any current kernel
use cases, because the `ZSTD_CCtx` is typically reconstructed between
compressions.
* Levels 1-4 see 5-10% compression speed improvements for inputs smaller than
128KB.

v1.5.6: https://github.com/facebook/zstd/releases/tag/v1.5.6
* Improved compression ratio for the highest compression levels. I don't expect
these see much use however, due to their slow speeds.

v1.5.5: https://github.com/facebook/zstd/releases/tag/v1.5.5
* Fix a rare corruption bug that can trigger on levels 13 and above.
* Improve compression speed of levels 5-11 on incompressible data.

v1.5.4: https://github.com/facebook/zstd/releases/tag/v1.5.4
* Improve copmression speed of levels 5-11 on ARM.
* Improve dictionary compression speed.
