The following patchset make xenguest save and restore functions
reentrant by moving the global variables into a structure pass
around functions.

Vincent Hanquez (7):
  create a domain_info_context structure to store guest_width and
    p2m_size for macros.
  create a global context structure to record global variables in save
  move restore global variable to a global static context
  move domain_info_context into the save_context
  move the domain_info_context into the restore_context
  pass the suspend_context through function and allocate the context on
    the save function stack.
  pass the restore_context through function and allocate the context on
    the restore function stack.
