sys/i386/i386 busdma_machdep.c
Log:
Allow bus_dmamap_load() to pass ENOMEM back to the caller. This puts it into
conformance with the mbuf and uio load routines. ENOMEM can only happen
with BUS_DMA_NOWAIT is passed in, thus the deferals are disabled. I don't
like doing this, but fixing this fixes assumptions in other important drivers,
which is a net benefit for now.
