In non-protected nVHE mode (non-pKVM) the host can directly access hypervisor memory; and unwinding of the hypervisor stacktrace is done from EL1 to save on memory for shared buffers. To unwind the hypervisor stack from EL1 the host needs to know the starting point for the unwind and information that will allow it to translate hypervisor stack addresses to the corresponding kernel addresses. This patch sets up this book keeping. It is made use of later in the series.

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.
