Update of /cvsroot/src/sys/arch/sparc/sparc
In directory netbsd1:/var/slash-tmp/cvs-serv23354

Modified Files:
        pmap.c 
Log Message:
Since all kernel regions are pre-allocated, we can safely copy kernel
mappings to a user pmap when it's created rather than at context
allocation time.  Also, do not copy the kernel's region administration
to every user pmap, especially since no memory appears to be allocated
to copy it into.

As a result of this, we must now switch to context 0 in both pmap_copy_page()
and pmap_zero_page() (XXX).
