Subject: Fix warning "failed to read pageflag_names entry" on Linux 4.6
References: bsc#978601
Git-commit: 7136bf8495948cb059e5595b8503f8ae37019fa1
Patch-mainline: 7.1.6

Fix for Linux commit edf14cdbf9a0e5ab52698ca66d07a76ade0d5c46, which has
appended a NULL entry as the final member of the pageflag_names[] array.

Without the patch, a message that indicates "crash: failed to read
pageflag_names entry" is displayed during session initialization in
Linux 4.6 kernels.
