The following C-state flags are currently mutually-exclusive and should not be combined: * IRQ_ENABLE * IBRS * XSTATE There is a warning for the situation when the IRQ_ENABLE flag is combined with the IBRS flag, but no warnings for other combinations. This is inconsistent and prone to errors. Improve the situation by adding warnings for all the unexpected combinations. Add a couple of helpful commentaries too.

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.
