Back in the day, rcutorture was about the only thing that tested off-stack CPU masks, but now any arm64 system with more than 256 CPUs tests it full time. In fact, it is necessary to hack the kernel to prevent such a system from testing off-stack CPU masks. This means that there is no longer much point in rcutorture going out of its way to test this. And given the differences in how CPUMASK_OFFSTACK is enabled in x86 and arm64, rcutorture would need to go out of its way. This commit therefore removes CONFIG_CPUMASK_OFFSTACK=y (and the CONFIG_MAXSMP=y required to enable it on x86) from TREE01. Signed-off-by: Paul E.

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.
