Make the macro maze consistent and prepare it for adding the RT variant for BH accounting. - Use nmi_count() for the NMI portion of preempt count - Introduce in_hardirq() to make the naming consistent and non-ambiguos - Use the macros to create combined checks (e.g. in_task()) so the softirq representation for RT just falls into place. - Update comments and move the deprecated macros aside Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Frederic Weisbecker <frederic@kernel.org> Link: https://lore.kernel.org/r/20201113141733.864469886@linutronix.de
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.
