Modified files:
sys/amd64/amd64 pmap.c
sys/i386/i386 pmap.c
Log:
Eliminate unnecessary invalidations of the entire TLB by pmap_remove().
Specifically, on mappings with PG_G set pmap_remove() not only performs
the necessary per-page invlpg invalidations but also performs an
unnecessary invalidation of the entire set of non-PG_G entries.
