[PATCH v4 12/20] RT: Allow current_cpu to be included in search

[Steven Rostedt <rostedt@goodmis.org>]

From: Gregory Haskins <ghaskins@novell.com>

It doesn't hurt if we allow the current CPU to be included in the
search.  We will just simply skip it later if the current CPU turns out
to be the lowest.

We will use this later in the series
