facility bits returned by stfle. The main purpose of that is debugging
aids which allows to test specific kernel behaviour depending on
specific facilities presence. It also affects CPU alternatives.

integer values to be additionally set or cleared (if value is starting
with "!"). Values ranges are also supported. e.g.:
