Following this email, I'm sending CVE-2016-3961 fix backport for Precise, taken
from upstream 3.2 stable kernel.  The actual fix is commit 103f6112f253
("x86/mm/xen: Suppress hugetlbfs in PV guests"), but in Precise a few other
commits are required.

Note that commit 7f9be77555bb ("s390/hugetlb: add hugepages_supported define")
is included here for completeness as this platform is actually not supported in

Dominik Dingel (2):
  mm: hugetlb: allow hugepages_supported to be architecture specific
  s390/hugetlb: add hugepages_supported define

Jan Beulich (1):
  x86/mm/xen: Suppress hugetlbfs in PV guests

  hugetlb: ensure hugepage access is denied if hugepages are not
