to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz
supplied to bus_dmamap_create). dm_maxsegsz is reset to the value supplied to
bus_dmamap_create when the dmamap is unloaded.
in jazz_bus_dmamap_create() disable BUS_DMA_ALLOCNOW for now
rather than return ENOMEM. Required by some PCI devices (like pciide(4)).
XXX needs re-think how BUS_DMA_ALLOCNOW should be handled.
XXX (we should use another flag for the jazz internal DMAC?)
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
Modify jazz_bus_dmamap_create() to allocate jazz dmatlb
if BUS_DMA_ALLOCNOW flag is specified and nsegment is 1.
In this case, jazz_bus_dmamap_load() just call
jazz_dmatlb_map_va() to map CPU VA space into jazzio
VA space with pre-allocated TLB entries (like dma.c does).
bus_dmamap_load_{mbuf,uio,raw} functions are not allowed
if dmamap is created with BUS_DMA_ALLOCNOW flag.
(i.e. ALLOCNOW is valid only for linear buffers.)
