sys/ia64/ia64 pmap.c
Log:
Turn pmap_install_pte() into a critical section. We better not get
interrupted while writing into the VHPT table. While here, make sure
memory accesses a properly ordered. Tag invalidation must happen
first so that the hardware VHPT walker will not be able to match
this entry while we're updating it and we have to make sure the new
new tag gets written only after the PTE is completely updated.
