Here's a somewhat experimental patch to improve soft offlining in hwpoison, but allowing hwpoison on free for not directly freeable page types. It should work for nearly all left over page types that get eventually freed, so this makes soft offlining nearly universal. The only non handleable page types are now pages that never get freed. Drawback: It needs an additional page flag. Cannot set hwpoison directly because that would not be "soft" and cause errors. Since the flags are scarce on 32bit I only enabled it on 64bit.
