mm/shmem.c: zero out unused vma fields in shmem_pseudo_vma_init() shmem/tmpfs uses pseudo vma to allocate page with correct NUMA policy. The pseudo vma doesn't have vm_page_prot set. We are going to encode encryption KeyID in vm_page_prot. Having garbage there causes problems. Zero out all unused fields in the pseudo vma.
