The pages containing these physical addresses will not be added to the free list and thus will effectively be ignored by the VM system. This is mostly useful for the case when one knows of specific physical addresses that have bit errors (such as from a memtest run) so that one can blacklist the bad pages while waiting for the new sticks of RAM to arrive. The physical addresses of any ignored pages are listed in the message buffer as well. Revision Changes Path 1.15 +29 -0 src/sys/vm/vm_pageq.c
