alc 377e76ab83 Optimize pmap_remove()'s handling of PG_G mappings. Specifically, ... instead of calling pmap_invalidate_page() for each PG_G mapping, call pmap_invalidate_range() for each range of PG_G mappings. In addition, eliminate a redundant call to pmap_invalidate_page(). Both pmap_remove_pte() and pmap_remove_page() called pmap_invalidate_page() when the mapping had the PG_G attribute. Now, only pmap_remove_page() calls pmap_invalidate_page(). Altogether, these changes eliminate 53% of the TLB shootdowns for a "buildworld" on a ZFS file system. On FFS, the reduction is 3%.
