Fujita Tomonori has already done this in these swiotlb commits:

  bb52196: swiotlb: remove unused swiotlb_alloc()
  3885123: swiotlb: remove unused swiotlb_alloc_boot()

about a month ago. You can find those changes in -tip:

  http://people.redhat.com/mingo/tip.git/README

and in linux-next as well.
