svn commit: r206256 - user/jmallett/octeon/sys/mips/mips

[Juli Mallett]

Author: jmallett
Date: Tue Apr  6 09:04:18 2010
New Revision: 206256
URL: http://svn.freebsd.org/changeset/base/206256

Log:
  o) Use CLEAR_STATUS rather than mtc0 zero, cp0_status, since the latter would
     disable all sorts of bits we care about.
