PM/Hibernate: do not count debug pages as savable
When debugging with CONFIG_DEBUG_PAGEALLOC and debug_guardpage_minorder > 0, we have lot of free pages that are not marked so. Snapshot code account them as savable, what cause hibernate memory preallocation failure. It is pretty hard to make hibernate allocation succeed with debug_guardpage_minorder=1. This change at least make it possible when system has relatively big amount of RAM. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Acked-by: Rafael J.
