Grygorii Strashko f259a7fdeb bus: omap_l3_noc: mark l3 irqs as IRQF_NO_THREAD 
[ Upstream commit 7d7275b3e866cf8092bd12553ec53ba26864f7bb ]

The main purpose of l3 IRQs is to catch OCP bus access errors and identify
corresponding code places by showing call stack, so it's important to
handle L3 interconnect errors as fast as possible. On RT these IRQs will
became threaded and will be scheduled much more late from the moment actual
error occurred so showing completely useless information.

Hence, mark l3 IRQs as IRQF_NO_THREAD so they will not be forced threaded
on RT or if force_irqthreads = true.

Fixes: 0ee7261c92 ("drivers: bus: Move the OMAP interconnect driver to drivers/bus/")

README 

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.
