    kernel: Use pmap_invalidate functions
    
    * Matt's commit brutally used invltlb and wbinvd instructions
      everywhere
    
    * These are now contained in pmap_invalidate_range(), which will be
      optimized later
    
    * As a rule of thumb, functions where cache and tlb handling cause
      avoidable performance degradation are tagged with "XXX not optimal"
