Pull futex updates from Thomas Gleixner: - Switch the reference counting to a RCU based per-CPU reference to address a performance bottleneck vs the single instance rcuref variant - Make the futex selftest build on 32-bit architectures which only support 64-bit time_t, e.g. RISCV-32 - Cleanups and improvements in selftests and futex bench * tag 'locking-futex-2025-07-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: selftests/futex: Fix spelling mistake "Succeffuly" -> "Successfully" selftests/futex: Define SYS_futex on 32-bit architectures with 64-bit time_t perf bench futex: Remove support for IMMUTABLE selftests/futex: Remove support for IMMUTABLE futex: Remove support for IMMUTABLE futex: Make futex_private_hash_get() static futex: Use RCU-based per-CPU reference counting instead of rcuref_t selftests/futex: Adapt the private hash test to RCU related changes
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
