New Revision: 190590
URL: http://svn.freebsd.org/changeset/base/190590

Log:
  fix a bug that it passed a incorrect flag BUS_DMA_ALLOCNOW to create
  a device specific DMA tag.  On amd64 it could exhaust all of bounce
  pages when bus_dma_tag_create(9) is called at malo_pci_attach() then as
  result in next turn it returns ENOMEM.  This fix a attach fail on amd64.
