Author: rnoland Date: Sun Mar 15 17:22:53 2009 New Revision: 189856 URL: http://svn.freebsd.org/changeset/base/189856
Log: Merge 189559 Fix the flags to bus_dmamem_* to allow the allocation to sleep while waiting for resources. It is really the load that we can't defer. BUS_DMA_NOCACHE belongs on bus_dmamap_load() as well.
