Modified Files:
      Tag: thorpej-bus-dma
        vm_page.c vm_page.h 
Log Message:
- Add a "boundary" argument to vm_page_alloc_memory(), which specifies
  a power-of-two boundary relative to 0 that no individual segment in
  the allocation may cross.
- While I'm there, fix some questionable logic in the inner allocation
  loop.
