  Log:
  o  In _ia64_save_context() clear the return registers except for r8.
     We write 1 for r8 in the context so that _ia64_restore_context()
     will return with a non-zero value. _ia64_save_context() always
     return 0.
  o  In _ia64_restore_context(), don't restore the thread pointer. It
     is not normally part of the context. Also, restore the return
     registers. We get called for contexts created by getcontext(),
     which means we have to restore all the syscall return values.
