davidg 96/06/13 21:34:37 Branch: sys/i386/i386 RELENG_2_1_0 Modified: sys/i386/i386 pmap.c Log: Brought in a fix from main branch: close a window in pmap_object_init_pt() that has to do with the PG_MAPPED flag not being set at the right time, and PG_BUSY the page rather than doing a vm_page_hold/unhold. This fixes a potential problem where some mapped pages might go unnoticed by other parts of the vm system, which can be a real problem if the page(s) are reclaimed.
