  SVN rev 205923 on 2010-03-30 20:05:22Z by marius
  
  MFC: r203830, r203831
  
  Use the SUNW,{d,i}tlb-load methods for entering locked TLB entries like
  OpenBSD and OpenSolaris do instead of fiddling with the MMUs ourselves.
  Unlike direct access the firmware methods don't automatically use the
  next free (?) TLB slot, instead the slot to be used has to be specified.
  We allocate the TLB slots for the kernel top-down as OpenSolaris suggests
  that the firmware will always allocate the ones for its own use bottom-up.
  Besides being simpler, according to OpenBSD using the firmware methods is
  required to allow booting on Sun Fire E10K with multi-systemboard domains.
