svn commit: r324786 - head/sys/powerpc/booke

New Revision: 324786
URL: https://svnweb.freebsd.org/changeset/base/324786

Log:
  Expand the TLB nest level mask to 3 bits to match the 32-bit mask
  
  This really doesn't change anything right now, because BOOKE_TLB_MAXNEST is only
  3, which fits into the 2 bits currently used.
