  Log:
  SVN rev 195779 on 2009-07-20 07:53:07Z by raj
  
  ARM pmap fixes.
  
  a)  nocache-remap problem
  
     When a page is remapped into a non-cacheable virtual memory region there
     was no associated write-back invalidate operation performed. We remove
     writeback of the original buffer size from bus_dmamem_alloc() and add
     appropriate L1/L2 flush operation.
  
  b) missing write-back invalidate operation
  
     In pmap_kremove a page is removed so we must do a write-back
     invalidate operation aligned to the page virtual address.
