Since commit 29d37e5b82f3 ("s390/protvirt: add ultravisor initialization")
vmax is adjusted to the ultravisor secure storage limit. This limit is
currently applied when 4-level paging is used. Later vmax is also used
to align vmemmap address to the top region table entry border. When vmax
is set to the ultravisor secure storage limit this is no longer the case.
Instead of changing vmax, make only MODULES_END be affected by the
secure storage limit, so that vmax stays intact for further vmemmap
address alignment.

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.
