Pull dma_*_writecombine rename from Ingo Molnar:
 "Rename dma_*_writecombine() to dma_*_wc()

  This is a tree-wide API rename, to move the dma_*() write-combining
  APIs closer in name to their usual API families.  (The old API names
  are kept as compatibility wrappers to not introduce extra breakage.)

  The patch was Coccinelle generated"
