Subject: [PATCH urgent 0/2] x86/unwind: an unwinder fix and debugging improvement

Patch 1 is a fix for an unwinder issue found by Boris.  Patch 2 is a
debugging improvement which helped diagnose the problem.

Patch 1 needs to go into tip/urgent for 4.10.  I'd argue that patch 2
should also go into urgent because it only affects the error path and it
makes the new unwinder warnings much more useful.

Josh Poimboeuf (2):
  x86/unwind: adjust last frame check for aligned function stacks
  x86/unwind: dump stack data on warnings
