Update of /cvsroot/src/sys/arch/sparc/sparc
In directory netbsd1:/var/slash-tmp/cvs-serv19688

Modified Files:
        pmap.c 
Log Message:
Fix bug in pmap_page_copy and pmap_page_zero that caused data corruption
when paging on Sun4m machines with SuperSPARC processors. Essentially,
the copy/zero operations were done via uncached memory accesses, which
bypassed the snooping logic of the write-back caches, causing stale data
to be copied or generated.
