Pull powerpc fixes from Michael Ellerman:
 "Fix a kernel crash in spufs_create_root() on Cell machines, since the
  new mount API went in.

  Fix a regression in our KVM code caused by our recent PCR changes.

  Avoid a warning message about a failing hypervisor API on systems that
  don't have that API.

  A couple of minor build fixes.
