["Michael Lorenz" <macallan%netbsd.org@localhost>]

Module Name:    src
Committed By:   macallan

Modified Files:
        src/sys/arch/mips/include: cpu.h cpuregs.h mips3_pte.h pmap.h
        src/sys/arch/mips/mips: bus_space_alignstride_chipdep.c mips_machdep.c
            pmap.c

Log Message:
support BUS_SPACE_MAP_PREFETCH in order to allow mapping device memory and
DMA buffers with cacheing disabled but things like write combining, relaxed
ordering etc. allowed when the CPU supports it
so far enabled only on Loongson, should work on R1xk and probably newer CPUs
