Pull irq fix from Thomas Gleixner: "A last minute fix for a regression introduced in the v6.5 merge window. The conversion of the software based interrupt resend mechanism to hlist missed to add a check whether the descriptor is already enqueued and dropped the interrupt descriptor lookup for nested interrupts. The missing check whether the descriptor is already queued causes hlist corruption and can be observed in the wild. The dropped parent descriptor lookup has not yet caused problems, but it would result in stale interrupt line in the worst case. Add the missing enqueued check and bring the descriptor lookup back to cure this" * tag 'irq-urgent-2023-08-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq: Fix software resend lockup and nested resend
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 Restructured Text 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.
