With the existing implementation of store_rps_map(), packets are queued in the receive path on the backlog queues of other CPUs irrespective of whether they are isolated or not. This could add a latency overhead to any RT workload that is running on the same CPU. Ensure that store_rps_map() only uses available housekeeping CPUs for storing the rps_map.

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.
