Christian Borntraeger a2fd64d6aa [S390] vmemmap: allocate struct pages before 1:1 mapping ... We have seen an oops in an OOM situation, where show_mem tried to access the struct page of a dcss segment. The vmemmap code has already created the 1:1 mapping but failed allocating the struct pages. In the OOM case, show_mem now walks the memory. It uses pfn_valid to detect if it may access the struct page. In the case described above, the mapping was established and pfn_valid returned true. As the struct pages were not allocated, the kernel oopsed. We have to ensure that we have created the struct pages, before we add a mapping pointing to the pages.
