Currently, struct snp_guest_msg includes a message header (96 bytes) and a payload (4000 bytes). There is an implicit assumption here that the SNP message header will always be 96 bytes, and with that assumption the payload array size has been set to 4000 bytes - a magic number. If any new member is added to the SNP message header, the SNP guest message will span more than a page. Instead of using a magic number for the payload, declare struct snp_guest_msg in a way that payload plus the message header do not exceed a page.

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 reStructuredText 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.
