The decompressor code is partially compiled with march=z900 so it is possible to print an error message in case a kernel is booted on a machine which misses facilities to execute the kernel. Given that the decompressor code also includes header files from the core kernel this causes problems for inline assemblies and other code where the minimum assumed architecture level is set to z10 in the meantime. If such code is also used in the decompressor (e.g. inline functions) z900 support must be implemented again. In order to avoid this and to keep things simple just raise the minimum architecture level to z10 for the decompressor just like for the kernel.

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.
