Author: andrew Date: Tue Jun 7 18:50:36 2016 New Revision: 301561 URL: https://svnweb.freebsd.org/changeset/base/301561
Log: Start to clean MIDR values using the CPUID scheme. We don't need to know the exact CPU we are running on to set the cpu functions. Relax the check to ignore the CPU revision. Even so this may still be too specific.
