nfit_test overrode the security_show() sysfs attribute function in nvdimm dimm_devs in order to allow testing of security unlock. With the introduction of CXL security commands, the trick to override security_show() becomes significantly more complicated. By introdcing a security flag CONFIG_NVDIMM_SECURITY_TEST, libnvdimm can just toggle the check via a compile option. In addition the original override can can be removed from tools/testing/nvdimm/. The flag will also be used to bypass cpu_cache_invalidate_memregion() when set in a different commit. This allows testing on QEMU with nfit_test or cxl_test since cpu_cache_has_invalidate_memregion() checks whether X86_FEATURE_HYPERVISOR cpu feature flag is set on x86.

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.
