[Steve Woodford <scw%netbsd.org@localhost>]

Module Name:    syssrc
Committed By:   scw
Date:           Sat Sep 28 10:53:58 UTC 2002

Modified Files:
        syssrc/sys/arch/sh5/include: pmap.h
        syssrc/sys/arch/sh5/sh5: pmap.c

Log Message:
- Add pmap_page_is_cacheable() to allow the bus_dma code to query the
  cacheable attribute of a mapping.
- Honour PMAP_NC in pmap_enter() using NOCACHE, instead of DEVICE.
- No longer need to re-fetch the ptel in pmap_pa_unmap_kva() as
  syncing the cache no longer risks causing a TLB miss.
