New Revision: 219336
URL: http://svn.freebsd.org/changeset/base/219336

Log:
  - Allocate the DMA memory used for the work area as coherent as at least
    the ataahci(4) and atamarvell(4) drivers share it between the host and
    the controller.
  - Spell some zeros as BUS_DMA_WAITOK when used as bus_dmamem_alloc() flags.
