Vincent reported that for states with a NULL startup/teardown function we do not call cpuhp_invoke_callback() (because there is none) and as such we'll not update the cpu_dying() state. The stale cpu_dying() can eventually lead to triggering BUG(). Rectify this by updating cpu_dying() in the exact same places the hotplug machinery tracks its directional state, namely cpuhp_set_state() and cpuhp_reset_state().

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.
