The .hyp.text section is supposed to be reserved for the nVHE EL2 code.
However, there is currently one occurrence of EL1 executing code located
in .hyp.text when calling __hyp_{re}set_vectors(), which happen to sit
next to the EL2 stub vectors. While not a problem yet, such patterns
will cause issues when removing the host kernel from the TCB, so a
cleaner split would be preferable.
Fix this by delimiting the end of the .hyp.text section in hyp-stub.S.

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.
