Looks good to me, but could you please rebase it on top of very latestest -tip, 
which has these bits from Andy included:

  1959a60182f4 x86/dumpstack: Pin the target stack when dumping it
  cb76c9398240 x86/dumpstack: Add get_stack_info() interface

... which create new conflicts with your series.

Thanks,

	Ingo
