[ Upstream commit 2d2e7075b87181ed0c675e4936e20bdadba02e1f ] The vmcoreinfo of a crashed system is potentially fragmented. Thus the crash kernel has an intermediate step where the vmcoreinfo is copied into a temporary, continuous buffer in the crash kernel memory. This temporary buffer is never freed. Free it now to prevent the memleak. While at it replace all occurrences of "VMCOREINFO" by its corresponding macro to prevent potential renaming issues.

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.
