svn commit: r276165 - head/sys/arm/include

[Ian Lepore]

Author: ian
Date: Wed Dec 24 03:02:12 2014
New Revision: 276165
URL: https://svnweb.freebsd.org/changeset/base/276165

Log:
  Define the old-school arm arch constants we still use internally based on
  the somewhat newer constants predefined by the compiler.  This will allow
  userland apps to use various machine/foo.h headers without CPUTYPE defined.

Modified:
  head/sys/arm/include/cpuconf.h
