[PATCH 2/2] mm: oom: show unreclaimable slab info when kernel panic

Kernel may panic when oom happens without killable process sometimes it is caused by huge unreclaimable slabs used by kernel. Although kdump could help debug such problem, however, kdump is not available on all architectures and it might be malfunction sometime. And, since kernel already panic it
