Hardware poisoned pages need special handling in the VM and shouldn't be touched again. This requires a new page flag. Define it here.Why can't you use PG_reserved ? That already indicates the page may not

Right now a page must be present with PG_reserved, otherwise /dev/mem, /proc/kcore
lots of other things will explode.
