When loading a DMA map, if the page's physical address exceeds the bounce
...
threshold, return an error to the caller (the caller will attempt to
bounce the transfer).

Adjust bus_dmamap_sync() for the R4000; in that case, use the stashed

Store the PA of the framebuffer in the softc. This eliminates the need
...
for the sc_phys callback; we can just store the PA in the grfbus attach
args, rather than a function pointer, which simplifies the code nicely.

Added Manuel Bouyer's recent i386 _bus_dmamap_load_buffer() patch :-

Handle the i386/PMAP_NEW copyout() differently:
...
Don't try to avoid faults when the PTEs are checked. Set pcb_onfault
instead so that trapwrite() is called as if the PTE were RO.
This is faster than explicitely ckecking the PDEs - at least in the
majority of calls where the PT is already present.
Thanks to Stefan Grefen for input and testing.
