** Description changed:

- hugetlbfs use may crash PV Linux guests
+ Xen and the Linux kernel through 4.5.x do not properly suppress
+ hugetlbfs support in x86 PV guests, which allows local PV guest users to
+ cause a denial of service (guest OS crash) by attempting to access a
+ hugetlbfs mapped area.
