svn commit: r265705 - head/sys/arm/arm

[Ian Lepore]

Author: ian
Date: Thu May  8 20:02:38 2014
New Revision: 265705
URL: http://svnweb.freebsd.org/changeset/base/265705

Log:
  Consolitate all the AP core startup stuff under a single #ifdef SMP block.
  Remove some other ifdefs that came in with a copy/paste that mean basically
  "if this processor supports multicore stuff", because if you're starting up
  an AP core... it does.
