The TLFS structures are used for hypervisor-guest communication and must exactly meet the specification. Compilers can add alignment padding to structures or reorder struct members for randomization and optimization, which would break the hypervisor ABI. Mark the structures as packed to prevent this. 'struct hv_vp_assist_page' and 'struct hv_enlightened_vmcs' need to be properly padded to support the change.

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.
