        src/sys/arch/hp700/hp700: mainbus.c
        src/sys/arch/hppa/hppa: pmap.c
        src/sys/arch/hppa/include: pmap.h

Log Message:
add a PMAP_NC flag for pmap_kenter_pa() to specific a non-cached mapping.
use this in mbus_dmamem_map() to fix corruption of DMA memory.
note that this TLB bit is ignored on some CPUs (PA7100 and probably
others of that era), so this doesn't fix the problem in general,
but it does work on newer models and will make things easier later.
