Kees Cook ff5d1a4209 sunvdc: Remove VLA usage
In the quest to remove all stack VLA usage from the kernel[1], this moves
the math for cookies calculation into macros and allocates a fixed size
array for the maximum number of cookies and adds a runtime sanity check.
(Note that the size was always fixed, but just hidden from the compiler.)

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
