This pull request contains the following branches:
fixes.2024.12.14a: Misc fixes, check if IRQs are disabled in rcu_exp_need_qs(),
instrument KCSAN exclusive-writer assertions, add extra WARN_ON_ONCE() check,
set the cpu_no_qs.b.exp under lock, warn if callback enqueued on offline CPU.
rcutorture.2024.12.14a: Torture-test updates, add rcutorture.preempt_duration kernel
module parameter, make the TREE03 scenario do preemption, improve pooling timeouts
for rcu_torture_writer(), improve output of "Failure/close-call rcutorture reader
segments", add some reader-state debugging checks, update doc of polled APIs, add
extra diagnostics for per-reader-segment preemption.
srcu.2024.12.14a: SRCU updates, improve doc for srcu_read_lock() in terms of return
value, fix typo in comments, remove redundant GP sequence checks in the
srcu_funnel_gp_start.

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.
