Generate kvm hypercall functions with a macro instead of duplicating the more or less identical code seven times. This also reduces number of lines of code. However the main purpose is to get rid of as many as possible open coded error prone register asm constructs in s390 architecture code. For the only user of kvm_hypercall identical code is created before/after this patch (drivers/s390/virtio/virtio_ccw.c).

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.
