Module Name:    syssrc

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

Log Message:
Another big round of pmap fixes/cleanup:

 - Use the PMAP_ASID_* constants from pmap.h

 - Track pmap_pvo_{enter,remove}() depth in the same way as mpc6xx's pmap
   (on which this pmap was originally based).

 - Some misc. tidying up and added commentary.

 - Use the VA/KVA to select whether to use the IPT or PTEG instead of
   checking which pmap is being operated on.

 - Add a handy DDB-callable function which will scan the kernel IPT
   looking for inconsitencies.

 - Finally, when unmapping a pool page, purge the data cache for the
   page. This permits write-back caching to be enabled for kernel
   text/data.
