  +++ This bug was initially created as a clone of Bug #165320 +++

  ---Problem Description---
  Paul Mackerras posted a patch to allow for hugepage backing of Hash guest(s) 
on a Radix host:
  http://patchwork.ozlabs.org/patch/880302/
  " KVM: PPC: Book3S HV: Fix VRMA initialization with 2MB or 1GB memory backing 
"

  With a 1GB backing in the Radix host, this patch allows the Hash guest
  to boot and allocate and use 16MB hugepages if needed (since backing
  page size must be larger than guest hugepage size).

  Once this is accepted upstream we should get it included in Ubuntu so that 
p8compat guests can use hugepages.

  ---Debugger---

  ---Steps to Reproduce---
   Back p8compat guest w/ 1GB hugepages, see that 16MB hugepages are available 
to reserve and use inside the guest.
