7 daysdoc: Add CPU Isolation documentationFrederic Weisbecker
nohz_full was introduced in v3.10 in 2013, which means this documentation is overdue for 13 years. Fortunately Paul wrote a part of the needed documentation a while ago, especially concerning nohz_full in Documentation/timers/no_hz.rst and also about per-CPU kthreads in Documentation/admin-guide/kernel-per-CPU-kthreads.rst Introduce a new page that gives an overview of CPU isolation in general.
