Update of /a/cvsroot/src/sys/arch/sparc/sparc
In directory pain.lcs.mit.edu:/a/tmp/cvs-serv28569

Modified Files:
        pmap.c 
Log Message:
Fix two cases of handling stale page table information:
1. when reading the referenced/modified bits the TLB entry must be flushed
   before reading the in-core version.
2. when wrapping up an entire segment in pmap_page_protect(), flush the PTPs
   from the TLB to prevent a table-walking operation to pick up stale - or
   possibly bogus - PTEs.

(hopefully I'll get a few of my hairs back now..)
