Xen regression and bug fixes for 3.15-rc1.

- - Fix completely broken 32-bit PV guests caused by x86 refactoring
  32-bit thread_info.
- - Only enable ticketlock slow path on Xen (not bare metal).
- - Fix two bugs with PV guests not shutting down when requested.
- - Fix a minor memory leak in xen-pciback error path.

Thanks.

David
