Subject: [PATCH] realtime: set unboud workqueues cpumask

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

The latest RHEL and RT kernels got support for setting the cpumask of unbound

workqueues in sysfs (https://bugzilla.redhat.com/show_bug.cgi?id=1176155).

This patch sets the unbound workqueues cpumask to the list of non-isolated

cores for the real-time profiles.
