Next patch will switch unbound kernel threads mask to housekeeping_cpumask(), a subset of cpu_possible_mask. So in order to ease bisection, lets first switch kthreads default affinity from cpu_all_mask to cpu_possible_mask. It looks safe to do so as cpu_possible_mask seem to be initialized at setup_arch() time, way before kthreadd is created.

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.
