Although the rcutorture scripting now deals correctly with full-up security-induced pointer obfuscation, it is still counter-productive for kernel hackers who are analyzing console output. This commit therefore sets the debug_boot_weak_hash kernel boot parameter, which enables printing of weak-hashed pointers for torture-test runs. Please note that this change applies only to runs initiated by the kvm.sh scripting. If you are instead using modprobe and rmmod, it is your responsibility to build and boot the underlying kernel to your taste. Please note further that this change does not result in a security hole in normal use. The rcutorture testing runs with a negligible userspace, no networking, and no user interaction. Besides which, there is no data of value that can be extracted from an rcutorture guest OS that could not also be extracted from the host that this guest is running on.

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.
