While the gcc plugin for automatic stack variable initialization (i.e. CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL) performs initialization with 0x00 bytes, the Clang automatic stack variable initialization (i.e. CONFIG_INIT_STACK_ALL) uses various type-specific patterns that are typically 0xAA. Therefore the stackinit selftest has been fixed to check that bytes are no longer the test fill pattern of 0xFF (instead of looking for bytes that have become 0x00). This retains the test coverage for the 0x00 pattern of the gcc plugin while adding coverage for the mostly 0xAA pattern of Clang.

README
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.
