Alan Cox 0d2e1c3e39 Clearing a page table entry's accessed bit (PG_A) and setting the ... page's PG_REFERENCED flag in pmap_protect() can't really be justified. In contrast to pmap_remove() or pmap_remove_all(), the mapping is not being destroyed, so the notion that the page was accessed is not lost. Moreover, clearing the page table entry's accessed bit and setting the page's PG_REFERENCED flag can throw off the page daemon's activity count calculation. Finally, in my tests, I found that 15% of the atomic memory operations being performed by pmap_protect() were only to clear PG_A, and not change protection. This could, by itself, be fixed, but I don't see the point given the above argument. Remove a comment from pmap_protect_pde() that is no longer meaningful after the above change.		2010-04-25 20:40:45 +00:00
